You said "CICS," so I have to cover quite a broad range of options here since I'm not sure about the user interface you'd be testing.
For Web and GUI user interfaces: IBM Rational Performance Tester. I particularly like the z/OS version -- z/OS is a very good place to put this kind of stress test tool, even if you're testing non-mainframe servers. That's because the capacity is pretty much free -- you schedule the tests at non-peak hours, but you can get enormous capacity if you need it for a moment -- and because the mainframe is a very, very good generator of lots and lots of IP traffic using a very small footprint (think OSA Express here). If you've heard of WebSphere Workload Simulator, this is the (much enhanced and converged) replacement. Yes, you can subcapacity license to a small LPAR if that's all you need (often the case). Beats setting up racks of servers that get used once a year (or month), that's for sure. http://www.ibm.com/software/awdtools/tester/performance/zos/ For TN3270, SNA, etc.: IBM Workload Simulator and/or Teleprocessing Network Simulator (TPNS). Take a look at both. You might like one or both. http://www.ibm.com/software/awdtools/workloadsimulator http://www.ibm.com/software/network/tpns You may also have interest in CICS Performance Analyzer ("CICS PA") and a monitoring tool like OMEGAMON XE for CICS. Hope that helps. - - - - - Timothy F. Sipples Consulting Enterprise Software Architect, z9/zSeries IBM Japan, Ltd.
