Do you want to stress test, or performance measure?
They are two different things. We use Load Runner to stress, and
RMF/SMF to measure. Of couse we are using WAS and not CICS, but we have
WSAM to measure that side.
That I am aware of Load Runner does not have any code that will run on
the mainframe. I know that Load Runner can query any SNMP server to get
information back, but the only SNMP information that I am aware of on
z/OS is network interface type stuff. We have had a Load Runner
consultant ask if DB2, z/OS, or CICS provided and performance
information via SNMP and the answer was no.

There was talk of mainframe connectors? There were tools that could measure
mainframe stress(os, cics, disk, cpu) but no specifics. The mainframe is a
one engine 192mip we handle 1,767,000 transactions during an 8 hour day.
Plus batch, plus DB2, and plus TSO. We run 100% and we want to see where
bottlenecks occur while we ramp up web transactions. We use RMF to measure
things and had it all analyzed it shows we need CPU. My boss wants a second
opinion as to why and how many does it take.

We had a sales pitch from LoadRunner but it was not mainframe oriented.
If it's a web application, why would the tool need to be mainframe
oriented?
You might have to use something like loadrunner to "whip" the
application, while measuring performance with your usual tools.
