APOLOGIES IF THIS IS A DUPLICATE POST - I RECEIVED AN ERROR MESSAGE FROM THE LIST.
Mark, A bit late for your issues but I am only just going back through all the old IBM-MAIN digests. Thanks for posting such a good explanation and I'm glad that our support were able to put you on the right track. Thanks.

In addition to that, the SVC is also used minimally with XCF processing, and that process, which has been in place for several releases, is to use the lowest SVC at the proper release level for this small amount of work. In this case, since both SVC 233 and SVC 246 were at r11 when CA 11 was started, XCF used SVC 233 for its needs. Then, when you reinitialized SVC 233 to version 12.0, control blocks and pointers changed, and XCF was broken, leading to the RC 83(01). You can then note that when CA 11 restarted and reestablished connection across XCF to the MUF, that there was no further problem. This, among other reasons, is why we have indicated for a long time that the CAIRIM process to REINIT should not be used to change release levels of the SVC. The recommendation has been that when introducing a new version SVC, that it be done at IPL time, or that a new SVC be used, and to not reinitialize a current Datacom SVC at a different level." ================================================== Of course "indicated for a long time not to..." means nothing to a new user, which from an MSM standpoint, I am. Also I reviewed the MSM admin manual, release notes and installation considerations and the migration checklist and there was no such warning about choosing a different SVC number. As matter of fact, the MSM install doc specifically says you can use the same number for a migration: SVCNO Specifies an SVC number for CA Datacom/MSM. Note: We do not recommend that you use the same SVC used by a running instance of CA Datacom r11. Limits: 200 through 255 Note: If you are an existing CA MSM customer and perform migration, the parameter value can be the same as in the previous release. Anyway... previous advise stands: Choose a new SVC number. :-) Regards, Mark -- Mark Zelden - Zelden Consulting Services - z/OS, OS/390 and MVS mailto:[email protected] Mark's MVS Utilities: http://www.mzelden.com/mvsutil.html Systems Programming expert at http://expertanswercenter.techtarget.com/ ---------------------------------------------------------------------- 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
