Problem summary

  • ****************************************************************
    * USERS AFFECTED: All Db2 13 for z/OS users.                   *
    ****************************************************************
    * PROBLEM DESCRIPTION: An ABEND 04E-00F31100 was returned      *
    *                      due to a hash miss.                     *
    ****************************************************************
    * RECOMMENDATION: Apply corrective PTF when available          *
    ****************************************************************
    When Db2 receives a request to associate a disassociated
    thread, Db2 will attempt a hash lookup to verify that the
    associating thread is recognized by Db2. However, in this case,
    there was a hash miss due to a serialization error with
    updates and lookups to the hash. As a result of the hash miss,
    Db2 returned a 00F31100 resulting in a hung Db2 agent which
    could be holding resources that are needed by other threads.
    

Problem conclusion

  • Db2 13 for z/OS has been changed to avoid a hash miss.
