Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: CICS stops using DB2 Group Attach when  *
  *                      DB2 is inactive and CICS is cancelled.  *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  A CICS system is using DB2 Group Attach, but following a failure
  of DB2, CICS has an indoubt UOW and the CICS system is then
  shutdown. The indoubt UOW still exists when CICS is AUTO started
  up. Should the DB2 subsystem still be inactive when CICS is AUTO
  started up and the CICS is then cancelled, the next AUTO start
  of CICS (and all subsequent ones) will result in the CICS system
  no longer using DB2 Group Attach, even after the indoubt UOW is
  resolved.
  

Problem conclusion

• DFHD2TM has restored the GLB_GROUP_OVERRIDE bit from the catalog
  when AUTO restarting CICS.
