Marcy, Do you do MQ clustering at your shop?

Albert (and others), As another follow-up to yesterday's z/Linux discussion on MQ "HA" alternatives, I've exchanged a few emails with Marcy Cortes from Wells Fargo banking and he/she sent me an IBM link specific to WebSphere MQ and "HA", which looks interesting. http://www.ibm.com/developerworks/linux/library/l-halinux2/ Part 2 specific to MQ http://www-128.ibm.com/developerworks/linux/library/l-halinux/index.html Here's Part 1. This looks like it might be good to test/try on z/Linux with two z/Linux guests running MQ. We already have one running z/Linux guest, zilmqa00, running two test QMGR's. We could close/create zilmqa01 and try the MQ HA above.

There's this http://www.ibm.com/developerworks/linux/library/l-halinux2/ which discusses MQ. We've got a project that wants to try this. Nothing special for z/Linux except that the DASD would be accessible by more than one LPAR and we need to make sure its not r/w on both. Requires minidisk cache off, CSE perhaps to protect having r/w by more than one system by accident. Marcy "This message may contain confidential and/or privileged information.

Your applications need protection from an *unplanned* outage, for a variety of reasons: - loss of power - z/VM abend - "I *meant* to shutdown my 2nd level system" And, of course, there are other reasons you may PLAN to turn off the machine, the LPAR, or VM (service).
