Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of DB2 10 and 11 for z/OS.         *
    ****************************************************************
    * PROBLEM DESCRIPTION: An ABEND0C4 may occur after a WLM       *
    *                      address space has been cancelled while  *
    *                      a stored procedure is in the midst of   *
    *                      a database command. An example is       *
    *                      an ABEND0C4 in CSECT DSNTDCST.          *
    *                      This could also lead to an overlay      *
    *                      of the thread's own stack.              *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    An ABEND0C4 may occur or a thread may overlay its stack during
    DB2 WLM termination processing, due to 64-bit stack being reset
    in the terminating agent after the WLM address space has
    been cancelled.  If a spawned system command task is
    referencing data on that stack, it may become corrupted
    resulting in an ABEND0C4.
    

Problem conclusion

  • DB2 has been modified to not reset stack during termination
    until all spawned tasks have completed.
