>I am almost ready to issue SETXCF START,MSGBASED and do this in our test Sysplex (2 LPARs). Before we jump in I wanted to know who else has tried this and have you seen any reduction in I/O to the couple data sets? Any problems? How many systems in your Sysplex? We have 7 LPARs currently in our production Sysplex down from 9 after we managed to push a couple sandbox systems into a test only Sysplex. > Hi Sam, We converted our 5 sysplexes to use msgbased event management. We did our largest sysplex (8 way) in January when they were all z/OS 1.8 systems. We did not experience any problems. The volume that has the CFRM couple dataset (also has the OMVS couple dataset) went from an average of I/O rate of 17.3 to 16.5 per second. Since that time we have converted about half of those systems in that sysplex to z/OS 1.9 without any problem. Our z/OS 1.9 systems don't have OA21917 (UA38901) or OA24563 (UA41002) applied. We are doing the other systems in a couple of weeks. Our next maintenance rollout will be RSU0806 which will have UA38901 and UA41002 applied. Per recommendation of XCF level 2 we will being going back to policy based event management to comply with the hold action for UA41002, because we will ipl half of the systems one month and the others the next month for the RSU0806 maintenance.
