APAR status

  • Closed as program error.

Error description

  • Where an MQ Stubs running on a single RIT Agent Engine runs out
    of MQ connections it stops picking up messages from the queue.
    

Local fix

  • This problem can be mitigated by only running one MQ Stub per
    RIT Agent Engine.
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED:                                              *
    * All users of Rational Integration Tester working with        *
    * WebSphere MQ.                                                *
    ****************************************************************
    * PROBLEM DESCRIPTION:                                         *
    * In minimizing the number of WebSphere MQ connections that it *
    * consumed, Rational Integration Tester caused significant     *
    * performance degradation when many MQ-based stubs were run in *
    * the same "engine" simultaneously.                            *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    

Problem conclusion

  • A fix for this issue was provided in version 8.7.0.1 of Rational
    Integration Tester. The "Allow connections to be managed
    automatically" option was added to the Advanced tab of the
    transport. This option tells Rational Integration Tester to use
    more MQ connections than it normally would in order to achieve
    better performance as more MQ stubs are run. If the option is
    cleared, Rational Integration Tester reverts to its previous
    behavior.
