Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users issuing DB2 commands via the IFI   *
    *                 interface on DB2 10 for z/OS.                *
    ****************************************************************
    * PROBLEM DESCRIPTION: ECSA storage leak from DB2 command      *
    *                      pools.                                  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    A -CANCEL THREAD command issued against an IFI READA job that is
    in the middle of executing a DB2 command will cause DB2 command
    processor recovery to be called.  The recovery may not free ESCA
    storage obtained during the command processing causing a storage
    leak.
    

Problem conclusion

  • Recovery logic is corrected to free storage obtained during
    execution of DB2 commands.
