Setting the Threshold Counts for List Monitoring z/OS MVS Programming: Sysplex Services Guide SA23-1400-00 |
|
For keyed list structures allocated in a coupling facility of CFLEVEL=9 or higher, use LISTSTATE=DEFINE to set or update the threshold counts that define the empty or not-empty state of a list. LISTEMPTY and LISTNOTEMPTY specify the values to be assigned as the empty and not-empty values. The not-empty value must be greater than the empty value. When the structure is allocated, the threshold count values are initialized to zero for all lists. For structures allocated in a coupling facility at CFLEVEL=8 or lower, LISTSTATE=DEFINE is ignored and the list empty and list not-empty threshold counts are always zero. Use IXLLSTC REQUEST=MONITOR_LIST to register interest in monitoring transitions between the empty and not-empty states. |
