John, Your z9 already has an internal coupling links and theoretically you can run a CF lpar in your z9. Since you have a single engine T01, IBM warns against doing this. You may want to check with your IBM business partner about getting sub-capacity pricing for IMS. You would pay for the amount of usage of IMS as opposed to monthly licensing fees. If you have a CF, it will likely take about a large a machine as you currently have to run it.

In order to save on IMS MLC charges (uses about 3%), we are investigating adding a second 'IMS LPAR' to our configuration (on same CEC). Currently we are running a 2096-T01. We run a production LPAR and occasionally a TECH sandbox LPAR. In 2012 we may be looking at replacing the T01 with a 2 engine z10 or z196 box. When I was discussing these plans with our IBM business partner, they indicated to run a SYSPLEX, we were going to needed to have a Coupling Facility - and that the CF engine was rather expensive. I had been reviewing the MVS Setting up a SYSPLEX manual. I am probably being dense, but it is not obvious that a CF is required. Are there any little z/OS shops out there doing this? Is a CF required? Is there any other special hardware or software required. We already run with XCF, WLM and LOGR datasets. I did see info in the archives in the 2009 thread 'how to - sysplex'. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
