Percentile response times are only useful if there are sufficient transactions
to make a useful calculation. 90% of 5 transactions is useless, 90% of 100
transactions gives useful measures.

Tommy,
This sounds like the PPRC links might be a bit slow or there are not enough of
them.
What do you have? Direct DASD to DASD or via a single SAN switch or even
cascaded? What settings (Gbps) are all the interfaces running at (you can ask
the switch for the switch and RMF for the DASD)?

Hi,
When using Debug Tool under CICS, every time a CALL statement is encountered
the debugger steps into the called program.
Is there a way to just have the called program called and not show its internal
workings.
We are using Debug Tool v14.1, z/OS v2.2, COBOL v6 and CICS TS v5.4.
Thanks
