Error description

  • The customer is testing TM1 10.2.2 on an AIX server with 21
    physical cores and 256 GB of RAM.  One of their tests consists
    of creating concurrent sessions of users navigating through TM1
    Applications when using Cognos Security for user authentication.
     ??What the test does: ?- Log into TM1 applications ?- Access to
    a published applications ?- Navigate the budget dimension to the
    fifth level ?- Close the session??When they have more than 15
    concurrent sessions the performance starts to degrade, to over
    30 seconds compared to 15 seconds baseline, and with 30
    concurrent sessions the performance is unacceptable (180 seconds
    compared to the 15 seconds baseline)??They are asking if there
    is a way of tuning TM1 Applications on IBM AIX to have an
    acceptable performance or if this is just the normal behavior.
