Unknown error. SerializationException RequestID when adding workflow to a Collection   When trying to add a workflow to a Collection, or create a new Collection, the following error is observed:   Unknown error. SerializationException RequestID: xxxxxxx     This prevents the workflow from being added to a collection. Additionally, you may notice that when you click on a Collection you see a 'Page Not Found' error.   Environment   Alteryx Server 2019.2   Diagnosis   Confirm you have recently upgraded your Server from version 2019.1 or lower to version 2019.2.     Cause   In 2019.2, a new interface for Collections, as well as some additional functionality for Collections, was added to the Gallery. A hard refresh is needed for this to render properly and your Collections to appear.     Solution   On the home page of your Gallery, perform a hard refresh by clicking Shift + F5 Confirm you now see the new grid interface for collections:     Additional Resources   How To: Manage a Collection

If you are upgrading your Alteryx Server from an older version to 2018.1 or greater, your MongoDB will be migrated from Mongo 3.0 to Mongo 3.4 as part of the process. This article details how to troubleshoot a potentially failed migration. 

Issue   As documented in the Server release notes (Server 2019.3), Alteryx Server version 2019.3 includes a new version of the embedded MongoDB (MongoDB functions as the server's  persistence layer ) . If you are upgrading your Alteryx Server from 2018.1 or greater*, your MongoDB will be migrated from Mongo 3.4 to Mongo 4.0 as part of the process.   *If upgrading from pre-2018.1, you will need to upgrade to a version between 2018.1-2019.2 before upgrading to 2019.3. Some users have reported the following error after the migration :   Inconsistencies between the original data and the new data may indicate a migration error. Check the C:\ProgramData\Alteryx\Service\Persistence\MongoDB_4_0\migration.log for any errors and contact Alteryx Customer Support for assistance. While the server may still run on the MongoDB 3.4, this may cause unexpected behavior in the long term. Should you encounter this error, it is important to troubleshoot it and make sure that your MongoDB is able to successfully migrate.   Environment   Alteryx Server Upgrading from a version  ≥ 2018.1 to version 2019.3   Diagnosis   If this error is encountered, the server itself will upgrade, but fail to start the service.   To determine which troubleshooting steps to take, we first need to check if the migration was actually successful or not :   Is there a MongoDB_4_0 folder under %ProgramData%\Alteryx\Service\Persistence? If there is a MongoDB_4_0 folder, check the migration.log file found under %ProgramData%\Alteryx\Service\Persistence\MongoDB_4_0, check in the spoiler below to see if it matches the successful migration shown here in the Spoiler:   A "successful" migration should have the following:   --Starting: C:\Program Files\Alteryx\bin\mongod3_4.exe --dbpath "C:\ProgramData\Alteryx\Service\Persistence\MongoDB" --port 27018 --Starting: mongo3_4.exe localhost:27018 "C:\ProgramData\Alteryx\Service\Persistence\MongoDB\getstats.js" This section starts up the original 3.0.4 database with the 3.0.4 executable and gets some stats on it. You'll see a list of collections and a count of items in them. --Starting: mongodump3_4.exe --host localhost --port 27018 --username user --password xxxxxxxxxxxxxxxxxxxxxxxxxxx --out "C:\ProgramData\Alteryx\Service\Persistence\MongoDB_PreUpgrade" ... {backup logs} --Stopping MongoDb --Starting: mongo3_4.exe localhost:27018 "C:\ProgramData\Alteryx\Service\Persistence\MongoDB\shutdown.js" ... 2019-09-04T11:21:48.413+0100 I NETWORK [thread1] Socket recv() An existing connection was forcibly closed by the remote host. 127.0.0.1:27018 2019-09-04T11:21:48.413+0100 I NETWORK [thread1] SocketException: remote: (NONE):0 error: 9001 socket exception [RECV_ERROR] server [127.0.0.1:27018] server should be down... This section runs a Mongo dump out to the PreUpgrade folder specified in the migration utility. You should see that the databases get dumped out to bson files. Hopefully, we won't see any errors in there. Once the backup completes the MongoDB service is stopped and the .js script verifies the MongoDB is not responding - any errors referencing the server being down, or the connection being forcibly closed is expected.   --Starting: C:\Program Files\Alteryx\bin\mongod.exe --dbpath "C:\ProgramData\Alteryx\Service\Persistence\MongoDB_4_0" --port 27018 --Starting: mongorestore.exe --host localhost --port 27018 "C:\ProgramData\Alteryx\Service\Persistence\MongoDB_PreUpgrade" ... {restore logs} --Starting: mongo.exe localhost:27019 "C:\ProgramData\Alteryx\Service\Persistence\MongoDB_34\createUsers.js" ... {user creation logs} --Stopping MongoDb --Starting: mongo.exe localhost:27019 "C:\ProgramData\Alteryx\Service\Persistence\MongoDB\shutdown.js" ... server should be down... We then start Mongo 4.0 server, and restore to the new MongoDB_4_0 directory from the previous backup that was just taken. Again, we should not see any errors in here. Then, the createUsers.js re-creates all the user accounts for each database. The MongoDB is then shut down again, and the .js script verifies the service is down.   --Starting: C:\Program Files\Alteryx\bin\mongod.exe --dbpath "C:\ProgramData\Alteryx\Service\Persistence\MongoDB_4_0" --port 27018 --Starting: mongo.exe localhost:27018 "C:\ProgramData\Alteryx\Service\Persistence\MongoDB\getstats.js" The new MongoDB is then started up again with Mongo 4.0, and we run getstats.js again, giving us a list of the collections and the count of the documents, similar to the first step. If everything looks good up to this point, the migration has likely been successful. If not, please see Solution B. Are the Alteryx System Settings pointing to the new MongoDB folder (MongoDB_4_0)? If everything looks good in the logs, but the service didn't start or something happened after this point, we should be able to manually change the persistence directory to point at the new MongoDB_4_0 directory, and in theory, the service should start up fine. See Solution A.   What version of Mongo is running after the attempt? In the persistence directory of the target database, there's an ASMongoDBVersion.bin file that seems to match up with the version of Mongo. If this does now show version 4.0, see Solution B.     Solution A   If the log contains all the information mentioned previously and the migration seems successful, but there’s an error starting the service:   Check that the Data Folder under Controller > Persistence is set to the MongoDB_4_0 folder. If is it not, edit it to point to this new folder. Restart the Alteryx Service.   Solution B   If the migration log doesn’t match the description above, give the migration another attempt:   1. Delete the folders MongoDB_PreUpgrade and MongoDB_4_0 2. Run the MongoDbUpgradeTo30.exe found here:   C:\Program Files\Alteryx\bin\MongoDbUpgradeTo30.exe     As always, don't hesitate to contact us over at Customer Support if you run into any trouble.

How To: Adding a Worker Node   Many customers need to expand their Alteryx Server environment to support a growing number of users, additional departments, increased data sizes, frequent job queuing, or a myriad of other reasons. This document walks through the process of adding a Worker Node to an Alteryx Server environment. These steps apply regardless of the size of the existing Alteryx Server environment.     Prerequisites   Product - Alteryx Server Additional required assets: Controller Hostname Controller Token Alteryx Server and Data installs ODBC Drivers   Procedure   Provision a new physical or virtual machine meeting the Alteryx Server minimum requirements, which are 4 cores, 16GB RAM, and 1 TB Disk. It is recommended to w ork with your Alteryx representative to understand what is an optimal system setup for your use cases, data set sizes, and business requirements.  Install applicable ODBC Drivers and configure System or User DSNs to match the existing Worker(s). In-Database connections should also be created for any data sources where In-Database processing is being used. Install Alteryx Server and any Data packages using the same install files from your existing Alteryx Server environment. This ensures version compatibility between the Controller and the new Worker Node. There are a couple of ways to verify the same version is being used. Check the version reported in Gallery at  https://MyGalleryHostname.com/#!help/version Check the version reported by Alteryx Designer running on the existing Alteryx Server machine. Ensure this matches the version reported by the file name of the Alteryx Server installable on the new Worker node. On the Alteryx Server Controller machine, open the System Settings and navigate to the Controller -> General section. Copy the Controller Token and save it for step 6. On the new Worker Node where Alteryx Server has been installed, launch the System Settings wizard. For the Environment Setup Type, choose Custom - Enable Worker.  Continue to the Controller -> Remote section. Enter your Controller Hostname and paste the Controller Token saved in step 4. Click Test to ensure the Alteryx Server version, Controller Hostname and Token match.  Configure the Worker and Engine settings as desired. Typically this involves matching the settings of an existing Worker but there are situations where it makes sense to have different settings across Workers, such as the number of workflows allowed to run simultaneously, QoS settings, Job tags, Map Rendering, etc... An example Worker Configuration Complete the System Settings wizard and validate the AlteryxService is Running on the new Worker node. Validate the new Worker shows up in the Gallery Admin -> Diagnostics page in the Workers panel.  Ensure the new Worker has access to any locally stored Macros or data sets. It is recommended to move all locally stored Macros and data sets to a network share or similar storage device that is accessible by all Workers, and then update Workflows based on the new locations. Storing files locally and copying to all Workers isn't recommended as it requires a method to keep them all in sync, increases data storage requirements, and introduces version differences across the environment.  Finally, run a few representative workflows through the new Worker to verify everything is working as expected.   Conclusion   With just a few simple steps a new Worker node can be added to an Alteryx Server environment to provide redundancy, higher throughput, shorter job queue times, and many more benefits.      Additional Resources   Worker System Settings Considerations for Scaling Alteryx Server Measuring and Scaling a Private Server Scaling a Private Server: Five steps to greater throughput

Guide to Gallery Data Connections - FAQ   Creating a Gallery Data Connection will allow ease of access for Alteryx users to connect to databases. The feature also allows the Alteryx Gallery and Database Administrators more governance over what connections are being made as well as who are making the connections.   What are the advantages of using a Gallery Data Connection?   Centralized area for Administrators to create and share database connections Avoids the need for IT to create database connections on each users machine individually Easy permissions management - access to the connections can be enabled or disabled instantly Users no longer need to know the connection information to connect to their data   What actually happens when you create the connection on the Gallery?   When you create a Gallery Data Connection, a record is created in MongoDB under the AlteryxGallery > dataConnections collection. { "_id" : ObjectId("5a5882573b910b5758cdd7e2"), "ConnectionString" : "4D35F08105015D7A81E5E274760D1C3529146D9516CACD028F1A353994C7DFB2ABAC8A99B1F284CCB7935B96F0FBD2EC9A9239B3305D4DE60D1C749C4E7BC65A597ED943742FB057EDD0F1882FFF98D6ED7888312215761DB1FA02B0EF425F9F98E645E73FB98481AC130D05F1A0CC0DBD42D4AC1F38E8DF8CA5759A6A4823F86C6FC212BD93263F83B90515DF6926B934FA086466A70992DF984C297A47C1DFFD749A642A6267B9FFC87B766127CE6C3D945FC64A8A25A2414DB2450AD6CAAD8D9202BFEBAF22C91B1371E1BA4C9CEB6E454B46B3BF4417D5280E53BCB5BE6AA734B", "PasswordSecured" : "", "ConnectionName" : "SQL_on_Gallery", "Subscriptions" : [], "Users" : [ "5a56197d3z920b5758cdd5f6", "503bac102031af71f8f8e479" ] } Once the connection is shared, it is also attached to that person's entry in AlteryxGallery > users collection. { "_id" : ObjectId("503bac145031af11f8f8e479"), "Curator" : true, "Anonymous" : false, "LicenseCurator" : false, "Sponsor" : "", "Email" : "aketchum@kantoleague.com", "FirstName" : "Ash", "LastName" : "Ketchum", ], ... ... ... "DataConnections" : [ "5baa469016ba3e2984be805e", "5bb2022216ba3e5ff4b02b38", "5baa5d0516ba3e2984be83ba", "5c1b721c16ba3e26d43ec3a8", "5bb2036b16ba3e5ff4b02be0", "5a5882573b910b5758cdd7e2", "5cfa1b39dd4214299419c703", "5b924bc516ba3e2178e41deb", "5d3f140edd421409506209a2", "5d3f1498dd421409506209a9" ], "CanSchedule" : true, "CanSetPriority" : false, "CanSetWorkerTag" : true, "RecaptchaResponse" : null }   What happens when the connection is used in Designer?   As soon as a user links their Gallery to Designer, a sync takes place that grabs all the connections they have access to and creates a file called GalleryAlias.xml in the user's* profile: C:\Users\USERNAME\AppData\Roaming\Alteryx\Engine *99% of the time this will be the user logged into the machine, but there is also the possibility that the user is right-clicking and running Designer as a different user. This file will be updated/synced when you: Open Designer. Open the Manage Data Connection window from Options > Advanced Settings > Manage Data Connections. Click Sync All in the Manage Data Connections Window:     What happens when you execute a workflow on the gallery that uses a Gallery Data Connection?     The Gallery 'translates' the connection from an XML file. One of the following will be used: GalleryAlias.xml __TemporaryAlias.xml The Gallery performs a permissions check. The permissions check ONLY applies to the user who uploaded the workflow. If the connection has not been shared with the uploader, it will error: Unable to translate alias SQL_on_Gallery The workflow is executed and the connection to the database is attempted. Any further any further errors will be around the connection string/driver itself, i.e. Error SQLDriverConnect: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.     What does 'translate the alias' mean?   This refers to the unpackaging and reading of the XML file to take the alias name (SQL_on_gallery) to the actual connection string. This must first happen before the connection to the database will even be attempted. If this fails for any reason, you get the following error:   Unable to translate alias X       What is the __TemporaryAlias.xml file, and when is it used?   When you publish a workflow to the Gallery that contains one of these connections, a file called __TemporaryAlias.xml is packaged with the workflow. You can see this file when you click Manage workflow assets during publication: By default, this asset is checked - it should be checked so that the workflow can use this XML to translate the alias. Once the workflow runs, it is pulled down and unpackaged into the Staging folder.   Which of the two XML files are used?   The Designer first will try to use the __TemporaryAlias.xml file. This is the preferred way, because as mentioned this XML file is packaged with the workflow,, meaning it can successful translate on whatever machine (worker) it runs on: If you don't package the __TemporaryAlias file, it will then try to use the GalleryAlias.xml file. As mentioned, since this is in the User's profile, you would need the Run As user to have this file synced and available in their profile. This method is not preferred. Another issue with this method is that the file will need to be synced on all worker machines.   What are the most important things to know to make sure my workflow will run successfully on the Gallery?    Always package the connection when publishing to the Gallery. From a permissions perspective, once the workflow is on the Gallery, it doesn't matter who runs the workflow for the translation to happen. Only the uploader of the workflow needs to have the connection shared with them.      

Configuring SAML on Alteryx Server for Active Directory Federation Services (ADFS)   Alteryx Server has the ability to use most identity providers that support the SAML 2.0 standard, and from my testing, ADFS is no exception! The following information will assist with configuring Alteryx Server to be functional with ADFS.   Please note the following information is based on third-party software and processes may be slightly different on older or newer versions of the software. The following was created against ADFS v4.0 running on Windows Server 2016 and Alteryx Server 2019.2.   Prerequisites   AD FS Server Account with access to perform administration tasks All users that will login must have an email address attribute Alteryx Server >= 2018.2 Account with access to perform administration tasks SSL/TLS Certificate Installed on Alteryx Server (Self-Signed certificate is not recommended)   Procedure   Verify that your Alteryx Server's Gallery function has been configured with SSL/TLS enabled on each Gallery node in the environment and that a proper SSL certificate is installed. Instructions are provided in the link above. This and following steps will require an ADFS administrator. Open the AD FD Management utility (Start > Windows Administrative Tools > AD FS Management) Click Relying Party Trusts from the console, then click Add Relying Party Trust... Click Enter data about the relying party manually and click Next. Type a Display name for the trust. I placed "Alteryx Server" here, but you can use a name that best identifies the connection for you, such as a server name or other easily identifiable name. Then click Next. Click Next on the Configure Certificate page. Check the box for Enable support for the SAML 2.0 WebSSO protocol. Type the URL of the Alteryx Server's SAML endpoint in the Relying party SAML 2.0 SSO service URL box, which typically will be the base URL of Alteryx Gallery with the addition of "/aas/Saml2". Once you have added the proper URL, click Next. Note: this endpoint may be case sensitive depending on settings in your environment. I would recommend entering it with the capitalization as shown in the screenshot and example below. Example: Gallery URL: https://trn-srv-07.cs.alteryx.com/gallery SAML Endpoint: https://trn-srv-07.cs.alteryx.com/aas/Saml2 In the Relying party trust identifier, type the same SAML endpoint as the previous step and click Add to add the URL to the list below. Click Next. Select Permit everyone from the Access Control Policy and click Next.

Server licensing and scaling is getting an update! In the past, server scaling has been handled by two separate products: the Alteryx Server Additional Node and the Alteryx Server 2 Core Add-On.  Alteryx Server Additional Node allows for horizontal scaling by licensing separate worker nodes which report to a controller, while Alteryx Server 2 Core Add-On allows for vertical scaling by enabling more computing power on the controller machine. These two separate products to scale server can cause friction for our end users, License Administrators, and IT Administrators alike as the scaling needs of the organization change. To better enable scaling, we're cleaning up our products and removing the friction with the Alteryx Server Additional Capacity product. How Does It Work? The new Alteryx Server Additional Capacity license will act as both a 'base' and an 'add-on' license. This means that during the activation process, the Alteryx Server Additional Capacity license will identify if there is already an Alteryx Server license present, if an Alteryx Server license is being activated simultaneously, or if no Alteryx Server licenses are present.  If a Server License Key (Alteryx Server, Alteryx Server Sandbox, or Alteryx Enterprise Server) is activated before or alongside the Alteryx Server Additional Capacity License Key, the Alteryx Server Additional Capacity license will act as an add-on and license two additional cores on the box. If the Alteryx Server Additional Capacity license is being activated alone, the product will act as a 'base', allowing the licensed machine to function as a worker node. How many cores does the Alteryx Server Additional Capacity license? One seat on the Additional Capacity key will license 2 cores. This applies to either scenario, whether the key is acting as a base product or as an add-on. The key will also automatically activate as many seats as needed to completely license the machine during the initial activation. What versions of Alteryx will the Alteryx Server Additional Capacity key work on? The Alteryx Server Additional Capacity key will work for versions 2019.2 or newer of Alteryx. If you are running a version older than 2019.2 and have been provided this product, reach out to the Fulfillment team (fulfillment@alteryx.com) to exchange the license key for the equivalent legacy product(s). Can I apply multiple seats on the same key or multiple unique keys of Alteryx Server Additional Capacity to the same Server? Yes! When activated, the Alteryx Server Additional Capacity product will identify how many cores are on the controller, and apply as many as needed to fully license the machine. If the number of cores available on the Alteryx Server Additional Capacity is unable to match the number of cores on a machine, the Additional Server Capacity license will activate as many seats as are available. For example, if you have an 8 core worker machine and only 2 seats on the Alteryx Server Additional Capacity key, both seats will be activated to license the device for 4 cores. Will the Alteryx Server Additional Capacity key retroactively replacing existing License Keys? We have no plans to replace the Alteryx Server Additional Node or Alteryx Server 2 Core Add-On License Keys from existing orders. However, all future orders that contain a server scaling product will be licensed with the Alteryx Server Additional Capacity product. All previously purchased server scaling products will continue to work on any version past 11.7. If you would like to upgrade to 2019.2, your previously purchased keys will have no trouble migrating. When is this product going to be available? The Alteryx Server Additional Capacity product will be launched and available for order with the release of 2019.2. Got another licensing question?

How To: Modify Gallery Session Timeout   This article shows how to modify the session timeout for the Gallery.  A session timeout specifies the number of minutes that a Gallery session can remain idle (inactive) before the session will be terminated.  The default session timeout value is 60 minutes.  When the session timeout occurs the user will be returned to the Sign In page:       Note: This setting applies to Built-in or SAML authentication only.  When using Integrated Windows authentication Alteryx does not enforce a session timeout as the user has a valid Windows session.       Prerequisites   Alteryx Server Authentication Type:  Built-in or SAML   Procedure   If you have a multi-machine Server environment, the following steps should be performed on the Gallery node(s) only.   Open Windows File Explorer and navigate to %PROGRAMDATA%\Alteryx\. Create a backup of the RuntimeSettings.xml file.  Open the RuntimeSettings.xml file in an editor and add the following line in the Gallery section: <SessionTimeout>20</SessionTimeout> Example RuntimeSettings.xml file with a 20 minute session timeout. Save the file and restart the AlteryxService.      Additional Resources   Gallery System Settings

How to migrate workflows between multiple Alteryx Server environments.

Alteryx Server System Settings Deep Dive - Engine     Introduction   This is the first in a series of articles to explore the Alteryx Server System Settings in depth to gain a deeper knowledge of what these settings are used for, and to provide a bit more context to help you determine the appropriate settings for your environment.  Every organization's deployment, use cases, and business requirements are different and thus there is no single configuration to fit all.  Having an understanding of the implications of each setting is vital in setting up your Alteryx Server for success.   We’ll explore the system settings for Alteryx Server as of 2019.2, through a series of articles for each component, starting with the Engine. The Alteryx Engine consumes Alteryx workflows and provides high-speed data processing and analytics functionality. This process can be entirely self-contained in Alteryx Designer, scaled across an organization by the Alteryx Service, or deployed in the cloud by the Alteryx Gallery.     Engine Settings   The Alteryx Server System Settings configuration wizard allows end users to modify the Engine configuration settings:   Engine Configuration   Any changes to the configuration settings in the System Settings wizard are applied to the RuntimeSettings.xml file, found at: %ProgramData%\Alteryx\RuntimeSettings.xml   Note, this file should never be modified through an editor unless specifically requested from Alteryx Customer Support.    A few of these settings are self-explanatory and sufficiently described in the Help.  However, many of these can often be confusing, and some have performance implications that aren’t well understood. The subsequent sections will dive into these settings in more detail.     Temporary Directory   “The Engine Temporary Directory is the place where temporary files used in processed workflows and apps will be placed. This setting should point to a location that is safe to write large amounts of files.”    The Engine Temporary directory is a parent directory in which each workflow executed creates a sub directory for storing data needed during the processing of the workflow.  Below is not an exhaustive list, but includes the most common types of data stored in the Engine temporary directory: Browse Tool Support - Every Browse Tool in the workflow creates a separate Alteryx Database file (.yxdb) that stores the contents of the data you see in the Browse’s Results and Configuration windows. The Browse Tool allows you to view all the data as opposed to a sample, and therefore the created .yxdb files could be quite large if the data sets being processed are large.  Therefore, the number of Browse Tools should not be prolific. NOTE: The temporary .yxdb files are only created when an Alteryx Workflow is run in Designer.  When workflows are executed through the Gallery or a schedule, browse tools are disabled. Browse Everywhere Support – The Browse Everywhere features allows you to click on the output anchor of a given tool and see a sample of the data at that point in the workflow.  All the data viewable in the various output anchors across a workflow is stored in one Alteryx Browse Everywhere file (.yxbe).  The size of this file is determined by how many tools are in the workflow multiplied by the “Memory Limit Per Anchor” size which will be discussed later in this article. NOTE: The temporary .yxbe file is only created when an Alteryx Workflow is run in Designer.  When worfklows are executed through the Gallery or a schedule, Browse Everywhere is disabled.  Tool Specific Support – Some tools create temporary files as part of their processing, for example the Download and Spatial Match tools. Paging / Swap Space – When the Engine's memory processing requirements exceed that of the “Default sort/join memory usage” setting (covered later in the article), temporary files (.tmp) are created to retain data that can be quickly retrieved later. The number and size of these temp files is determined by the size of the data sets being processed, and the types of tools in the workflow.  The Engine 101 Basics blog does a great job of describing how certain “blocking” tools need access to all rows of a dataset to process it.  The presence of these blocking tools will drive up the likelihood that the Engine will need to use temporary files to complete its processing.   Example Engine Temp directory for a running workflow where the files described above are evident. These files are all deleted when the workflow processing is complete.  For a Designer user, this means when the Workflow is closed or upon initiating another execution of the Alteryx Workflow in Designer.  For a Server user, this means upon completion of the workflow execution.  Note, the Engine Temporary Directory is used when running workflows from Alteryx Designer.   When running on an Alteryx Server, the Worker’s “Workspace” directory is used to store these temporary files.   Recommendations It is highly recommended to set the Temporary Directory to a different drive than your system boot drive (C:\). If the C:\ drive on Windows fills up, the system can become unresponsive or even unstable.  If an additional drive (D:\) fills up, no harm is done to Windows and the system will remain functional. The Temporary Directory is used for frequent I/O operations to read and write data. Configuring this directory on Flash/SSD storage is a great way to improve performance by minimizing the wait times for those read & write operations to complete.  See the Measuring and Scaling a Private Server blog post for more information.    When running in Designer, minimize the use of Browse Tools when working with large data sets to reduce workflow processing times and keep the Temp directory from filling up. Understand that temporary directories can grow quite large during processing if working with large data sets and doing lots of sorts, joins, or other blocking operations. As an example, we saw a temporary directory grow over 150GB in size processing a 12GB data set.  Your mileage will certainly vary based on data set sizes and tools used.     Memory Limit Per Anchor “Define the maximum amount of memory to use to consume data for each output anchor for tools in a workflow. The default value typically does not need to be changed.”    This setting applies when running in Designer only as mentioned in the Browse Everywhere section.  The Browse Everywhere feature allows a user to see a sample of the data (up to Memory Limit Per Anchor in size) at the output anchor of every tool.  The default value is 1024 KB (1MB).     This workflow would produce a .yxbe file of approximately 12MB. This is a great way to analyze your data without using the Browse tools which will write the entire dataset contents to disk.     A sample of the data can be seen in the output anchor of each tool. In the event of the Temporary Directory not having enough space to create the .yxbe file, the following will be logged: Warning - Alteryx: Disk space on temp drive running low.  No browse everywhere data created.   Recommendations Keeping the default Memory Limit per Anchor setting makes sense for most scenarios. In situations where you are building a workflow with a very large data set, and the 1 MB sample just isn't enough to give you the information you need, but the full Browse tool is too heavy, it might make sense to increase this value. However, make this change on the local Designer (laptop/desktop) and not the Server which is used by many end users.  This change can be made in Designer under Options -> User Settings -> Edit User Settings: Designer users can override the Memory Limit per Anchor in the Advanced User Settings.     Default sort/join memory usage "This is the minimum amount of memory that the Engine will consume while performing operations such as Sorts and Joins within a workflow or app. Generally, this value should not be changed.”    The Engine "Default sort/join memory usage" setting and the Worker “ Maximum sort/join memory usage ” setting have generated a lot of questions that I hope this section clears up. There are three key points to clarify:   If making changes, the Engine "Default sort/join memory usage" is the setting that should always be specified and what we'll focus on in this article. For Designer users, this value can be specified in the Options --> User Settings --> Edit User Settings wizard: The Default Dedicated Sort/Join Memory Usage setting This setting is both a minimum and a maximum.  It's a minimum in that this amount of memory will be "committed" to each Engine process (running workflow)  regardless of how much memory the Engine actually consumes processing the workflow.  Therefore this amount of memory is reserved for each Engine process and not usable by other applications.  It's a maximum in that the Engine process will not consume more memory than this value. If the Engine needs more resources than the setting specified, it will start utilizing the temp (swap) space as described earlier.  If the workflow launches additional processes, such as from the Run Command tool, or R by the use of Predictive Tools, those processes are NOT controlled by this setting. Other processes are not controlled by the Engine Default Sort/Join Memory Usage setting The setting is not specific to Sorts and Joins.   As described in the Engine 101 Basics blog, “blocking” tools require access to all data for execution.  This drives up memory consumption.  Sort, Join, and Summarize operations are the most commonly used blocking tools but there are many others, easily identifiable with a red border in the Periodic Table of Alteryx Tools .  Any workflow executing these blocking tools with high row count data sets (millions of rows) will consume lots of memory.   If the Sort/Join memory setting requested exceeds the amount of physical RAM available, Alteryx will revert to a lower value that is safe to commit.  In that case a message like the following will be logged in the Alteryx Engine logs: 00:00:0.003 - Alteryx: Allocating requested dedicated sort/join memory would be more than available physical memory.  Reverting to 2912MB of memory.                  Recommendations Only make changes to the Engine "Default sort/join memory usage" setting if necessary.  The default value works well for most scenarios, and we routinely see problems occur when this value is changed without understanding when and how to configure it. The below recommendations are just starting points. It is always recommended to configure and then test with representative workflows and usage patterns.  Then reconfigure and repeat the process until the optimum values are identified. To properly calculate a reasonable Sort/Join Memory value, we must know how many workflows will be configured to run simultaneously. This number should be determined by a server sizing exercise, and for existing customers, also take into account data from the Server Usage Report, such as queue times and job execution times.  For Designer only users the number of simultaneous workflows will be 1. For non-predictive workflows, a good starting point would be: The 4GB reservation ensures the OS and other system services are not starved of memory.  If the machine will also be supporting the Gallery and Controller, then that reservation should be increased to at least 8 GB. If the predictive tools will be used then additional memory should be reserved for the R processes.  In that case a good starting point would be: The expectation is that the machine will only be used for Alteryx processing and not shared with other applications. If other applications will also be running, then their memory requirements need to be factored into the equations above. Again, the above recommendations are just starting points. It is always recommended to configure and then test with representative workflows and usage patterns.  Then reconfigure and repeat the process until the optimum values are identified.     Default number of processing threads   “Define the number of processing threads tools or operations can use. The default value is the number of available processor cores plus one. Generally, this value should not be changed.”   This setting is determining the number of processing threads that multi-threaded tools can use.  The multi-threaded tools are identifiable in the  Periodic Table of Alteryx Tools .  (Sort and some Spatial tools highlight the list).  Configuring a higher value here may facilitate more parallelism which may result in faster completion times in the execution of these multi-threaded tools, assuming the machine has the capacity to use the specified number of threads.  Specifying a higher than needed thread pool size can lead to an over-committed system in which the CPU is constantly context switching between threads which may produce longer processing times.    In Windows Task Manager, the "Logical processors" metric shows us the maximum number of concurrent processing threads on that server:       Recommendations To reduce workflow run times using multi-threaded tools, set the Default number of processing threads equal to the number of Logical processors. If the server will be executing multiple workflows simultaneously, consider using a lower value to ensure that no workflows are starved of CPU.     Run engine at a lower priority   “Select if you are running other memory intensive applications simultaneously. It is also recommended that this setting be checked for a machine configured to run the Gallery.” The Windows Scheduling Priorities doc is a great resource to understand why this setting is important.  To summarize, Windows assigns time slices of CPU time to processes based on their priority level.  Applications with a higher priority will be given more CPU time than applications with a lower priority.  This ensures higher priority applications get more processor time when the system is heavily utilized.   Most applications default to “Normal” priority.  Some critical Windows processes have a “High” priority, such as the logon and desktop window manager processes.  Alteryx installs all Server components (AlteryxService, Gallery, Designer, etc…) with the “Normal” priority.  By default, this includes the Engine as well.  This could lead to a scenario where resource intensive workflows are running, and the Alteryx Service layer, the Gallery, or even Designer are struggling to get CPU time since they all share the same priority level.  This also could inhibit mouse & keyboard inputs, and background disk flushing.   Running the Engine at a lower priority will allow these components to remain responsive even during periods of heavy workload processing.   Recommendations This setting should be enabled in all Server deployments (Controller, Worker, Gallery) to ensure Windows components, and the Alteryx Server components always get priority over intensive Engine processes.    Conclusion   The Alteryx Engine has many settings that can impact workflow performance and resource consumption.  Understanding how each of these settings are used by the Engine, and how some settings even impact others, will allow administrators to configure Alteryx Server optimally for their environment and usage.      References https://help.alteryx.com/server/current/admin/Configuration/SystemSettings/Engine.htm https://community.alteryx.com/t5/Alteryx-Knowledge-Base/The-Alteryx-Engine-101-The-Basics/ta-p/405649 https://community.alteryx.com/t5/Engine-Works-Blog/The-Periodic-Table-of-Alteryx-tools/ba-p/64120 https://community.alteryx.com/t5/Engine-Works-Blog/Measuring-and-Scaling-a-Private-Server/ba-p/8786

Issue:  Alteryx Service will not Start and LastStartUpError.txt contains "No suitable servers found: `serverSelectionTimeoutMS` expired: [connection refused calling ismaster on 'localhost:27018']: generic server error" code: <mongodb:13053>   By Default, the LastStartupError text file can be found at C:\ProgramData\Alteryx\Service     Error Code: No suitable servers found: `serverSelectionTimeoutMS` expired: [connection refused calling ismaster on 'localhost:27018']: generic server error" code: <mongodb:13053>   Environment   Product - Alteryx Server Version(s) 11.8+ Diagnosis   Check the mongod.lock file is > 0KB in size   Identify where the MongoDB is installed from the Alteryx System Settings under Controller > Persistence > Data Folder Navigate to that folder in Windows File Explorer Confirm the size of mongod.lock Cause   Alteryx Server had an unclean shutdown.   Solution   If the mongod.lock file does have data inside (1KB usually), we recommend to first  backup your persistence database  (in case of corruption) before proceeding. Alternatively, in step 1 below, rename the file instead of deleting if you do not have a backup.   Delete/rename the mongod.lock file e.g: mongod.lock renames to mongod.old Right-click on a blank space in the window and select New > Text Document Alternatively, if you do not have this option you can create a new text file in Notepad and save the file into this directory. If you run into issues saving into this directory directly, you can save the file to your Desktop and then move into the folder where MongoDB is installed Name the document mongod.lock Make sure that File Extensions are visible, otherwise this file will actually be mongod.lock.txt Open a Windows Command Prompt and navigate to the \Alteryx\bin directory e.g.  cd "\Program files\Alteryx\bin"​ Start up the MongoDB service just to make sure everything is clean: mongod --dbpath "folder path from system settings" --auth --port 27018   With an unclean shutdown it may take a few minutes to reallocate the data.  Look for a line that says "Waiting for connections on port 27018"  When it appears, hit CTRL+C on your keyboard to shutdown the service. Start up the AlteryxService.  This can be done via: Command Prompt with:  sc start AlteryxService​ From the Services window   Next Steps if the Mongod.Lock file was empty (0KB)   Open a Windows Command Prompt and navigate to the \Alteryx\bin directory e.g.  cd "\Program files\Alteryx\bin" Run the AlteryxService in test mode to identify the actual error  AlteryxService test If you are unable to easily identify what is causing the error, send the service log files (path found in System Settings->Controller->General) to Alteryx Support    

Issue   Workflows being run on Gallery or Scheduler return with an error Access is Denied for various file types. The Alteryx Server is not able to perform expected actions (Signing into Gallery, Service unable to start, etc.). The Service or Gallery logs reference that the Service is unable to open/read specific files with Access Denied.   Cause   This issue has multiple potential causes, all related to permissions: The Run As account does not have permission to dependency or file being referenced. The Alteryx Service account does not have permission to dependency or file being referenced. The Alteryx Service account does not have the proper permissions required to run the Alteryx Service.   Diagnosis   Isolating the Run As Account   A workflow being run on the Server will run as whichever account is set up in either workflow credentials, the Worker Run As, or the Alteryx Service Account. The account in workflow credentials will take priority, followed by the Worker Run As, and then the Alteryx Service Account.  For more information on Server Run As accounts and permissions, see this article.      To check the accounts being used at each level, look in the following locations: Workflow credentials are established on Gallery Admin’s page under Workflow Credentials. The Worker Run As account is set under Alteryx System Settings > Worker > Run As. The Alteryx Service account can be found under Services (please see Isolating the Service Account to find which account is running the Service).   A quick test to see if the Run As account will have access to the proper dependencies is to log into the Worker node of the Server as the Run As account, open and run the problematic workflow in Designer.    If the Run As account does not have access to certain locations that should seem accessible by the Server, please go to Solution A.   Isolating the Service Account (error returned from workflow execution)   If workflow credentials are not enabled and there is no Worker Run As account, the Server will run workflows on the account outlined by the Alteryx Service. To find the account that is running the Alteryx Service please follow the steps below:   1. Open Services (Windows menu -> Run -> services.msc)   2. Find Alteryx Service; Right-click on the service and select Properties. Click the Log On tab.     If the Alteryx Service account does not have access to certain locations that should seem accessible by the Server, please go to Solution A.   By default, the Alteryx Service account will be run as the Local System. The Local System account normally has pre-determined permissions. More information on the Local System, see this article.   If the Local System Account does not have access to certain locations that should seem accessible by the Server, please go to Solution B.   Isolating the Service Account (error found in Service logs)   When reviewing the Service or Gallery logs, if the Service account does not have access to required folders and/or files, there will be an Access Denied error. An example is below: Exception caught by ErrorHandler and marshalled to Client,"Alteryx.Cloud.Common.Exceptions.ForbiddenException: Access denied If receiving the above error, please go to Solution B.   Solution A   If the Run As account does not have the proper permissions to access a dependency, either grant the appropriate permission to the account for the dependency or change the Run As account to an account that does have permission.   Solution B   If Service or Gallery logs are displaying Access Denied, ensure that the Alteryx Service account has all the required permissions needed to run the Alteryx Service.   If the Alteryx Service account is set to Local System, please work with IT to enable more permissions for the Local System or assign a Service account to the Alteryx Service that can have all the required permissions.

Workflows have moved to a different Private Studio   This is a hidden feature designed to allow workflows to be moved between studios. It's a holdover from our Public Gallery which is the original base for Alteryx Server.   What happened Workflows disappeared from a Private Studio and are now in another one    Environment   Product - Alteryx Gallery All Versions     Cause The following conditions being met will result in the workflow moving.   Source studio = free Target studio = paid User is last one in source studio User is moved to target studio via access key (admin or user invoked) All workflows move with the user regardless of ownership   Defensive Measures There is no way to reverse the move of these workflows. The best defensive measure is to take regular backups of MongoDB, as restoring the database is the only way to revert the change.   Additional Resources   Alteryx Server Backup and Recovery: Part 1

How To Deactivate Users on Gallery (An Alternative to Deleting Users)   If Gallery Admins would like to rescind access for specific Users on a Gallery, two methods are recommended. Deleting Users from Gallery is not supported and there is no Admin option available to delete Users entirely. The options outlined below will deactivate or revoke access.   Prerequisites   Product - Alteryx Server   Procedure A: Built-In Gallery   1. Navigate to the Subscription page under the Gallery Admin portal -> Subscriptions. Add a new subscription, specific for Deactivated Users.     2.  Add the User to the subscription by click either the Add Artisan or Add Member button.   3. Navigate to the Users page under Gallery Admin portal -> Users. Change the role of the User to No Access. **To see the 2018.4 version layout, select the Profile Button on the User. To revoke access, switch the Active button to No.   Procedure B: Windows Authentication Gallery   1. Navigate to the Subscription page under the Gallery Admin portal -> Subscriptions. Add a new subscription, specific for Deactivated Users.   2. Add the User to the subscription by click either the Add Artisan or Add Member button.   3. Navigate to the Permissions page under Gallery Admin portal -> Permissions. Search for the User and choose No Access.

SAML (Security Assertion Markup Language) is a standardized way for exchanging authentication and authorization credentials between different parties. The most common use for SAML is in web browser single sign ons. Starting in 2018.2, Alteryx Server supports SAML. So far, SAML in Alteryx Server has been specifically validated on two providers; Ping One and Okta. In this article we will review how to configure SAML on your Alteryx Server for   PingOne.
