A lot can be automated, but the task is not as simple as it seems. In addition to the issue of order, there's also the issue of symbols and the IPL parameters from the HMC. As others have mentioned, good configuration control processes will help to avoid the need to frequently compare parameters.

BUT.... Most parms can be overridden by commands. If/when a system is IPLed, it will revert to the parms as specified in parmlib. If you have proper change control, those parms have been updated, too. But, if you had that level of change control, you probably would not be in the situation of trying to compare parms from one system to another. So it probably does make sense to start with the easy techniques, but you may still have to slog through checking the parmlibs against each other the hard way. But I have two thoughts on the above: Do you have a sandbox where you can IPL those systems in a test mode and compare the displays with the running systems? Are there (supported?) ways to generate parmlib members from what's actually in effect? (ISTR that JES2 does.) If so, they'll probably be in he same formats and orders, thus easy to compare. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
