1. To delete a CICS® structure for a named counter (NC) pool, stop all named counter pool servers for the structure. If there are no connections to the structure, use the STOP system command to stop the named counter server. If there are connections, issue the MODIFY system command to disconnect active CICS connections: F server, CANCEL where server is the name of the named counter pool server.
2. When all servers are disconnected, if the existing data needs to be saved, unload the structure contents to a sequential data set by running the named counter pool server program DFHNCMN with the FUNCTION=UNLOAD option as described in theCICS System Definition Guide .
3. 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 SETXCF FORCE,STRUCTURE,STRNAME=DFHNCLS_poolname system command.

The saved structure contents can be reloaded later from the sequential data set into a new structure by running the named counter pool server program DFHNCMN with the FUNCTION=RELOAD option.
