DB2 Version 9.7 for Linux, UNIX, and Windows
The high watermark for the actual rows returned of DML activities at all nesting levels in a service class or work class. For service classes, this monitor element returns -1 when COLLECT AGGREGATE ACTIVITY DATA for the service class is set to NONE. For work classes, this monitor element returns -1 if no COLLECT AGGREGATE ACTIVITY DATA work action is specified for the work class. For workloads, this monitor element returns -1 when COLLECT AGGREGATE ACTIVITY DATA for the workload is set to NONE.
For service classes, when you remap activities between service subclasses with a REMAP ACTIVITY action, only the rows_returned_top high watermark of the service subclass where an activity completes is updated. High watermarks of service subclasses an activity is mapped to but does not complete in are unaffected.
