  • 1.  Cognos 11.2.4 - Burst reports execution time increased Tremendously

    Posted Mon January 23, 2023 08:28 AM
    Hi, 

    We upgraded to Cognos 11.2.4 from 11.2.2. Since the upgrade, our burst reports that used to take 5 minutes to run are now taking 2+ hours. Is anybody seeing  a similar issue?

    Any help is appreciated. 

    Thank you!

    Hi Ramanpreet,

    Did you try to update (just save) all your burst reports within the new version? Did you check if you are using (if necessary) the correct driver (located in <cognos_installation>/drivers?

    Best regards,

    Hi Patrick,

    Thank you for quick reply.

    I tried opening and saving the report. Also, made sure I have correct driver version but still same issue. 

    Thank you!

    We are sorry to hear that you're experiencing this issue.

    If you are covered under an IBM Support contract, I would recommend opening a support case so our team can review the issue holistically.
