- Use the performance keyword only when tuning cannot improve system
performance and performance is below explicitly stated expectations.
- Record actual performance, expected performance, and the source
of the expected performance criteria. Include the order number and
page of the source document. If you contact the IBM® Support Center, you will be asked for this information.
- Specify the performance keyword as PERFM.
- If the problem is related to a function or module, specify the
function or module name as a modifier keyword.
Example:
If the module is IFG0194A and the function is OPEN, specify the keywords
as follows:
IFG0194A OPEN
- If possible, isolate the probable source of degraded performance
to a specific DFSMSdfp subcomponent.
- See Table 1.
