1. Use the IRLM status command to determine if any DB2® member that is in the data-sharing group has retained locks. If a member has retained locks, reinitialize the associated DB2 member to recover the retained locks.
2. Initiate® a normal shutdown of all DB2 members with the following command:

    STOP DB2 MODE(QUIESCE)

   The DB2 cache structures for the group buffer pools are also deleted automatically.

3. Deletion of the structure may need to be forced. See Deleting structures with SETXCF FORCE for more information on forcing deletion of persistent structures with the SETXCF FORCE,STRUCTURE,STRNAME=strname system command.
