Using the Sysplex Coupling Facility › Coupling Facility Management › Rebuild the Coupling Facility Structure

Rebuild the Coupling Facility Structure

After you have updated the CFRM policy with new structure attributes such as SIZE or INITSIZE, you can use the SETXCF z/OS operator command to rebuild the coupling facility structure characteristics based on the new CFRM policy changes. The rebuild is performed with minimum disruption to the connected systems.

To initiate the rebuild process based on the new CFRM policy structure attributes, while connected systems remain connected to the structure, enter:

SETXCF START,REBUILD,STRNAME=strname

During the rebuild process, the system defers any requests that are issued while the structure is unavailable. These requests are processed after the rebuild process has completed.
