Deleting region status server pools

You can delete a region status server pool by deleting its coupling facility list structure. You might do this for a service upgrade, or when a clean sysplex restart is required.

Before you begin

You can delete a structure only when no servers are connected to the pool; otherwise, MVS™ rejects the command.

About this task

For example:

SETXCF FORCE,STRUCTURE,STRNAME=DFHCFLS_poolname

You can verify that the pool has been successfully deleted by issuing the XCF command shown here:

D XCF STRUCTURE,STRNAME=DFHCFLS_poolname

Note that if you delete a region status server structure while CICS® regions and workload are running, you disable CICSPlex® SM WLM optimized functions.

What to do next

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).
