Barry Merrill discussed the reporting aspects, but SMF SID can most definitely affect a running system if--as has been common practice for decades--SID is used implicitly for other non-SMF functions. Various components of z/OS or ISV products may implicitly use SID unless some value is explicitly coded.
We once IPLed a system in which the SID was changed accidentally. It appeared to IPL OK, but tape processing was inoperative. Turns out that MIM, which controlled all tape allocations, was set up to recognize a specific set of systems that were identified by SID. The MIMplex no longer recognized this system and would not allow it to join up. I'd say that if you go through a complete IPL sequence, get everything running with no screw ball anomalies, then you're probably OK until you get to reporting. . .

Our SMF SID parameter is the same for our production Lpar and the corrosponding Test Lpar for one of our boxes. I changed the SID for the Test MVS machine, as that would not affect the production system. We run two sysplexes, which do not talk to each other. DASD is all separate. We have a Prod sysplex, and a Test sysplex. My question is, will this affect anything? Is there any program products that could be affected by changing the SID? I read the whole chapter in the Init & Tuning Reference, and I didn't see anything that would matter to us. We found this out when we were running the SCRT report for January. We just capped both our machines, and are going to variable workload charging. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
