Requesting a Lock Operation as Part of an IXLLSTM Request

z/OS MVS Programming: Sysplex Services Guide
SA23-1400-00

To perform a serialized operation, one in which a lock operation is performed together with an IXLLSTM operation, specify the LOCKOPER parameter on the IXLLSTM request. If list services cannot perform both the lock operation and the IXLLSTM operation, the request fails.

You can specify the following LOCKOPER values on an IXLLSTM request:
  • NOTHELD
  • HELDBY

See LOCK: Performing a Lock Operation for detailed information about the LOCKOPER parameter.
