  • 1.  DM Server performance with 14 SP2

    Posted Apr 10, 2018 08:17 AM

    After upgrading to 14 SP2, we noticed that DSM Explorer reacts more slowly.

    Also, before SP2 (=GA), we could perform several parallel OSIM installation (beside the OS, a lot of SW packages are being delivered to the clients). Now we notice a general slowness. 

    The MDB is remote, but this is not causing the delays.

    We experience the same issues on all DM's so it cannot be a single's server problem.

     

    Clearing the cam queue seems to help a bit for a while, but then the slowness comes again.

     

    Any tip? Is there maybe some setting which needs to be changed?

    Check the notification server cache file:

    ..\CA\DSM\appdata\cfnotsrvd.dat

     

    This file grows with every DSM Explorer connection, and decreases when DSM Explorer gracefully closes.

     

    The problem is when DSM Explorer does not gracefully close-- it leaves notification subscribers in the cfnotsrvd.dat file, which will cause the DM to push notification messages via CAM messaging, to the remote IP.  If the remote IP is not online/available/responding via CAM, it will cause messages to pile up on CAM on the DM, which will result in an overall application performance issue.

     

    If the file is >50kb, I recommend stopping CAF, deleting the file, and restarting CAF.  This will clear the slate, and perhaps resolve your performance issue.

     

    Performance issues typically require troubleshooting, so I do recommend you log a case with Support.  The above suggestion is common enough, so I figure worthwhile to check.
