Deleting or emptying coupling facility data table pools
You can delete a coupling facility data table pool using the MVS™ SETXCF command to delete its coupling facility list structure.
About this task
For example:
SETXCF FORCE,STRUCTURE,STRNAME=DFHCFLS_poolnameYou can delete a structure only when there are no servers connected to the pool, otherwise MVS rejects the command.
When you attempt to start a server for a pool that has been deleted (or attempt to reload the pool), it is allocated as a new structure. The newly allocated structure uses size and location attributes specified by the currently active CFRM policy, and other values determined by the server initialization parameters (in particular, MAXTABLES).
