After all data sets using a resource pool are closed, delete the resource pool by issuing the DLVRP (delete VSAM resource pool) macro. Failure to delete a local resource pool causes virtual storage to be lost until the end of the job step or TSO/E session. This loss is protected with a global resource pool. If the address space that issued BLDVRP terminates without having issued DLVRP, the system deletes the global resource pool when its use count is 0.

To delete an LSR pool with a SHRPOOL identification number other than SHRPOOL=0, you must use the SHRPOOL parameter to indicate which resource pool you are deleting. If both a data resource pool and an index resource pool have the same SHRPOOL number, both will be deleted.

If the DLVRP parameter list is to reside above 16 MB, the MODE=31 parameter must be coded.
