New statement cache filter options<br />
IFCID 316 offers a set of improvements that are beneficial for analyzing SAP workloads. The<br />
most important change is the ability to provide filter values for the first table name and the<br />
SAP accounting qualifiers End User ID, ABAP Program Name, and SAP Transaction/Batch<br />
Job. Figure 3-6 shows the redesigned Specify a Filter panel. These filters are passed directly<br />
to the instrumentation facility interface (IFI) and are applied by DB2 when requesting<br />
statement cache data. Therefore, analysis turnaround times can be dramatically reduced,<br />
and the results are not susceptible to IFI memory restrictions.<br />

In addition, the following new qualification and ranking options are now available:<br />
► Qualification (Threshold for ...):<br />
– Number of RID list failures (because of DB2 limits)<br />
– Number of RID list failures (no storage)<br />
► Ranking (Highest ...):<br />
– Accumulated Elapsed Time<br />
– Number of RD list failures (DB2 limits)<br />
– Number of RID list failures (storage)<br />
– Accumulated CPU time<br />
– Accumulated wait time for synchronous I/O<br />
– Accumulated wait time for lock request (lock/latch request for DB2 9)<br />
– Accumulated wait time for asynchronous execution unit switch<br />
