Hello,

 This is a new server settings parameter introduced in CU27 for Nav 2017. What is optimum settings for this field "RetainNonInteractiveSession "to prevent a massive amount of entries in the Session Event table.

Thanks,

Neeta

    Hello,

    Thank you for asking. I would say that unless you have the problem that the setting was invented for, just leave it as default.

    The reason for the setting was systems with high numbers of Web Service calls, which ended up creating a lot of entries in the "Session Event" table. This is typically not a problem, as there are jobs that automatically purge the table, but in some cases this cleanup-job would take so long, that users were not able to log in because of locks on the table.

    So if you see errors caused by locks on "Session Event" table. Or if you notice that the table contains a very large number of records, then this setting is for you. Otherwise I would leave it alone.

    I hope this answers your question?

    Hello,

    Thank you for posting on the Forum.

    From feedback from the North America Technical Team for Microsoft Dynamics NAV Support:

    “Optimum” is quite subjective. A client may certainly lower either of these settings if the number of records are too large.  Many environments have these set to 1 day as they generate many session event records.

    Server Configuration Dynamics NAV 2017

    From the config….

    <add key="SessionEventTableRetainInterval" value="90.00:00:00" />

     <!--

       Specifies the time interval that sessions in the Session Events table remain before they are deleted.

       This value has format d.hh:mm:ss.

     -->

     <add key="NonInteractiveSessionsLogRetainInterval" value="5.00:00:00" />

     <!--

       Specifies the time interval that background and web service sessions remain in the Session Event table before they are deleted.

       This value has format d.hh:mm:ss.

     -->

    Thank you again for posting on the Forum.
