Using the browser navigation buttons does not correctly change a query

On pages with a query panel (Assets, Calibrated Assets, Reports, etc.), the browser back button does not work as expected. When a user presses the back button, the URL in the browser changes, but the filters do not.

Workaround:

Remove the filter using the X button next to the property selection field instead.

Stored test results can be sent to the incorrect server when client registration is changed while forwarding is in progress

If the store & forward plugin is already loaded and forwarding steps, it continues to forward to the original server connection even if the server is changed.  It will not switch servers while there are current transactions on disk and still successfully forwarding them.  Since simply switching the master does not invalidate the old API key, then if the server is still accessible, the forwarding plugin does not know that it should switch to the new master.

Workaround:

There is currently no known workaround for this issue.

Windows login account cannot be used as TDM User Account

Logging into the Windows SystemLink servers with different user accounts can create issues with TDM services like DataFinder in case when one of these login accounts is also being used as SystemLink TDM User Account.

Workaround:

Assign a specific user/account to SystemLink TDM services.

Installing "NI SystemLink TDM Analysis Add-On" can fail on Windows operating systems with non-western character sets

Especially on Windows operating systems with non-western character sets, the character length of the temp folder can be that long, such that files temporary extracted during (pip) installation can result in a full file path exceeding the max path limit of the operating system.


Workaround:

Change the temp path location to a folder with a shorter name, for instance C:\temp.
Or enable the Long path support for Windows as described here:

Transport Layer Security (TLS) negotiation of SCHANNEL-based SystemLink clients with NI Web Server fails intermittently

When the NI Web Server is configured with a self-signed certificate, some installations seem to have issues with SystemLink clients failing to send HTTPS requests. Clients fail with a generic Secure Socket Layer (SSL) error even though the self-signed certificate on the server is valid, and correctly installed on the client. The client's browser and HTTP clients like cpprest correctly trust NI Web Server. But any .NET-based HTTP client using SCHANNEL will exhibit this behavior. When this happens, all targets registered to the server will fail in all sorts of strange ways, resulting in strange client-side behavior product wide.

We have determined that the behavior above is attributed to unusual TLS version negotiation within .NET Framework 4.6.2 itself, which configures SCHANNEL with unusual version negotiation behavior. Here is the Microsoft documentation explaining the problem: https://docs.microsoft.com/en-us/dotnet/framework/network-programming/tls#configuring-security-via-the-windows-registry. According to this documentation, the behavior was changed in .NET Framework 4.6.3, whereas NI SystemLink uses 4.6.2.

Workaround:

As per Microsoft documentation, there is a set of registry keys which force 4.6.2 version of .NET Framework to default to the OS-level TLS negotiation behavior. We have confirmted that applying the registry keys to affected targets fixes the problem. You can find the set of registry keys along with values to apply in this documentation from Microsoft - https://docs.microsoft.com/en-us/dotnet/framework/network-programming/tls#configuring-security-via-the-windows-registry


Please contact NI if you have trouble with the registry keys.

Steps may incorrectly be marked as failed or timed out when using Store and Forward

Stored requests that do not have a unique timestamp can be incorrectly sorted and forwarded out of order. Depending on the order, different symptoms can occur:
  • If the Main sequence step occurs before the create result step, the step and all of its children fail to be created
  • If the Update step occurs before the create step, the update step will fail and the step will remain in the running stage and will eventually timeout

Workaround:

There is currently no known workaround for this issue.

Store and Forward Service may crash when there are too many items in quarantine

Batch forwarding, a new feature added in the 21.5.1 SystemLink Client reads the entire store directory into memory before forwarding. When the store directory is too large, this results in significant memory consumption, which can crash the service or result in undesirable side effects.

There is currently no known workaround for this issue.

Reports may not be attached to Test Results when using Store and Forward in the TestStand TestMonitorClient

XML, PDF, System Software, and Asset Reports may not be properly attached to the test result when store and forward is being used. This is caused by a race condition that may mark the result update as complete before the reports have been attached, or if the System does not currently have a connection to the SystemLink Server.

SystemLink Client performance degradation over time

The SystemLink TrayApp on the client system starts a tcp-server in order to get job notifications. This mechanism enables pop-up notifications informing the current user that a job started/completed. This has to work for any user that can login to that system and for Windows Server we have to support the use-case of multiple users being logged-in simultaneously; each user has their own tcp-server on its own port.

The ports are persisted on the disk in this location: C:\ProgramData\National Instruments\Systems Management\NIMinionConfig\ports

Over time, this list may grow and will include users that are no longer active on the system. For each port that fails to connect, there is a 2 second timeout when attempting to connect. This results in delays of 2 seconds multiplied by the number of inaccessible ports for each job.

    Workaround:

    Manually delete the files corresponding to the users that are no longer logged in to that system.

    TDM DataFinder Optimize Database function does not reduce database footprint when run after data is deleted from MariaDB

    In version of DataFinder Server Editions prior to 2014, executing the TDM DataFinder Optimize Database function would reduce the database footprint roughly proportional to the volume of records deleted from the database. This function could be used to help cleanup database after archiving old data. This does not function as expected when run after data is deleted from MariaDB

    Workaround:

    Setup multiple DataFinder instances and archive the entirety of the oldest database at a time, cycling through several instances to achieve desired volume of historical data storage.
