Problem summary


    

  • ****************************************************************
* USERS AFFECTED: All CICS Users.                              *
****************************************************************
* PROBLEM DESCRIPTION: Task priority might be set incorrectly. *
****************************************************************
In SET_PRIORITY the old priority is saved but the new priority
is not updated. The most recent priority value is therefore not
available to later processing.

    



Problem conclusion


    

  • CICS has been changed to set task priority correctly.
