I have gotten many problems with the SMF dump process - anything from slow dumping, ENQs accross SysPlex and also during IPL, Timing issues, running out of space, name it. I have gotten all of them and mentioned here on IBM-MAIN... >And parms on the VSAM Define for the MANx files (like STRNO or RLS) that might >help?

All VSAM datasets in the SysPlex are on exclusive Non-SMS volsers. Nothing else are there. This alone reduce fragmentation. All my other SMF datasets are in exclusive SMS management/dataclass/storage group/storage class. These SMFPRMxx settings resolved many other dump timing problems: BUFUSEWARN(25 or 50 depending on LPAR) BUFSIZMAX(512M) (Larger is better. See above) MAXDORM(0500) (Why filling it up?) DDCONS(NO) Depending on speed of filling up, I want to have automation to kick off 'I SMF' automagically as few times as possible. Let z/OS do it (dump/clear VSAM dsn) instead forcing it. The idea is - dump more often in smaller chunks. Then I have activated custom IEFU29 process which are kicked off automatically whenever there is a 'I SMF'. Another tailoring I did was having every 3 - 6 hours a job which forced a 'I SMF' about one minute apart for all LPARs in the SysPlex. Setup your automation software to handle IEE366*, *IEE986E, *IEE985A, IEE979* messages. After midnight, everything written out are then copied and MODded on a monthly dataset. Repeat all actions for having a working backup. Of course, my SMF setup may or may not work in YOUR environment - YMMV. No LOGSTREAM for me for now. Hope that helps you!
