Determining Whether to Have User Data Field (UDF) Order Queues z/OS MVS Programming: Sysplex Services Guide SA23-1400-00 |
|
UDF order queues, available only in a cache structure allocated in a coupling facility of CFLEVEL=5 or higher, provide the ability to have a queue associated with each cast-out class, which the coupling facility maintains in order by user-data field. You can use IXLCACHE REQUEST=READ_COSTATS to determine the lowest user-data field for any entry in the cast-out class when UDF order queues are present. |
