Dynamic SQL Cache Statistics
This panel provides additional details about the dynamic SQL cache.
The statistical data requires that monitor class 1 and IFCID 318 are started. This might be accomplished by starting the Near Term History collector.
With this panel, you can identify problem statements in the dynamic SQL cache.
One line of output is produced for each unique dynamic SQL statement.
To sort output by display column move the cursor under the display column heading you want and press the sort key (PF10).

- Elapsed Time
- The accumulated elapsed time for the SQL statement.
- Wait Time
- The accumulated time spent waiting in Db2 for all causes.
- Get - Pages
- The number of Getpage requests performed for the SQL statement.
- Sync Reads
- The number of synchronous Buffer Read operations performed for the SQL statement.
- Sync Writes
- The number of synchronous Buffer Write operations performed for the SQL statement.
