Restarting resource structures

You can cold start a resource structure by shutting down any CQS systems that connect to the resource structure, deleting the resource structure on the coupling facility, and restarting a CQS to reallocate the resource structure.

1. Shut down any CQS systems that connect to the resource structure.
   For example, issue the following command, where cqs_name is the CQS subsystem name.

   P cqs_name

   The response will be shown as follows:

   CQS0021I CQS SHUTDOWN COMPLETE
   CQS0101I CQS CLEANUP SUCCESSFUL

2. Delete the resource structure on the coupling facility.
   For example, issue the following command, where structure_name is the resource structure name.

   SETXCF FORCE,STRUCTURE,STRNAME=structure_name

   The response will be shown as follows:

   IXC353I THE SETXCF FORCE REQUEST FOR STRUCTURE
   structure_name WAS COMPLETED:        
   STRUCTURE WAS DELETED              

3. Restart a CQS. CQS initialization will reallocate the resource structure.
   For example, use the CQS startup procedure.
4. Verify that the resource structure is empty.
   For example, issue the following command, where structure_name is the resource structure name.

   D XCF,STR,STRNAME=structure_name

   The response will be shown as follows:
