APAR status

  • Closed as program error.

Error description

  • An application that is holding a large number of locks may take
    a long time to complete lock escalation.  As a result, other
    applications may experience lock waits, timeouts, deadlocks.
    Lock escalation is not interruptable, and as a result, the
    system may appear to be hanging.  Currently, the only options
    are to forcibly bring down DB2, or wait until the lock
    escalation completes.
    
    This APAR will add an enhancement to allow the lock escalation
    process to be interrupted, so that an agent that is in lock
    escalation can be forced.
