Dataspace monitoring
If the DB2/VM Data Spaces feature has been installed, the dataspace class
records for each interval and for each monitored database:
-
the number of dataspace reads, writes and pagefaults in each pool
-
the save interval, the target and the current working set
-
the dataspace hit ratio
-
the dataspace access hit ratio
Sample Report
The SQL/MF extended counters provide following additional statistics about
the dataspace subsystem:
-
the number of VM SAVE requests resulting from the SAVEINTV specification and
the average number of pages saved per request
-
the number of VM RELPAGE requests resulting from the TARGETWS specification and
the average number of pages released per request
-
the number of prefetch requests and the average number of pages prefetched
per request
