Error description

  • DFHTSPT has not set up stype correctly prior to calling the
    method to create the TSqueue. This means we call tsqueue_init
    with a value of 0 in stype. This results in the method not
    setting tsq_main on, which implies the queue must be aux. Hence
    we end up creating an auxiliary queue.

    ****************************************************************
    DFHTSPT handles the create of temporary storage queues used
    internally for CICS requests such as EXEC CICS START commands.
    Unlike DFHEITS, which handles EXEC CICS WRITEQ commands to
    create queues, DFHTSPT does not set the location attribute of
    the REQID queue from a TSMODEL selected as the best match to use
    when creating it. This means that a default of AUXILIARY
    is used for the queue location, even if the matching TSMODEL
    specifies MAIN. This can lead to under-exploitation of the
    ECDSA, growth of data on DFHTEMP, and the potential for unwanted
    queues to be rebuilt across a warm CICS restart.

Problem conclusion

  • DFHTSPT has been changed to use the location attribute from the
    TSMODEL for the queues it creates. Note - the XTSPTIN GLUE can
    also be used to set a queue location, and this takes
    precedence over a TSMODEL's setting.
