1. Stop all DB2® members in the data sharing group.
   If it is not possible to stop all the DB2 members, see DB2 Data Sharing: Planning and Administration for information. The following command can be used for a normal shutdown of all DB2 members:

   STOP DB2 MODE(QUIESCE)

   DB2 list (SCA) structures are also deleted with the preceding command.

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

Restart DB2 to re-initiate use of the structure.
