Hi Rebecca, the saveqmgr program does not store the permissions set with the setmqaut command. You need another supportpac (I guess MS0I), to save the authorities too.
Nevertheless, saveqmgr stores only the qmgr configuration, not the qmgr itself. This means, you will be able, to create a qmgr with the same objects. This qmgr may have the same name, but another qmgr ID. This may cause problems when you use MQ clustering (see my mail before).

Bill, if the only reason you're dong the backups nightly is to be sure you have the required object definitions, then why don't you just plan to create a new qmgr with the correct name and reload the objects/security stuff from the definitions? You can back those up using the saveqmgr SupportPac and the amqoamd command (OK, I may have that last one wrong since I did it from memory and I'm too tired/lazy to go look it up -- but it's at least close). Depending on the particular qmgr and application in question and how critical it is, we may use any one of the following: Veritas clustering Two qmgrs with client channel tables Simply create a new qmgr on another box and reload the definitions It all depends.... (Don't you hate it when people respond with that?)

Good thing YOU have the headache, not me! Actually we have hardware clustering already established - the HP High Availability stuff, and we test it every month. The test server(cluster) is in a different location. I initially installed MQ with clustering, but took it out when I had a problem that required a PTF that was only a month old. Too "bleeding edge" for my taste. And it turned out that our development situation got a bit crazy, and on an almost daily basis I was rewiring my channels so the MF test system was sending message to the Unix test server, then production to training, then test to training....you get the picture.... I couldn't have done it with clustering. And we do not store any data on the queues for more than 30 seconds....The only reason for a regular copy is to pick up any changes I make to MQ objects.

Speaking of which.....Why wouldn't you consider CLUSTERING. It would make things simple for you. You would have automatic failover. Another secenario would be to use some sort of Hardware/Software clustering. I have been in installations whee Veratas was used. It worked well and you can (maybe) forget about the clustering. Unfortunatly you have to invest in the technology on a hardwar, software and education level. But it can be used for other critical application other than MQ. You did not mention how people are connecting to the QMGR in question. If it is client you have a channle table failover option and can have the queue manager runing on the other box to accept the work. Not much change necessary there. You mentioned that you would copy the environment over at night. WHY???? Are applications in your group using the QMGR as a storage device or is it a business req. If you think about it. In any good MQ environment the messages should only stay on the queues long enough to get them out the door. Otherwise you have an issue. Restoring a QMGR from an image from a couple of hours (?) ago would imply the QMGR is stale or out of sync. You may have to consider the re-processng of old messages. This could be as devastating as loosing messages. As you can see this discussion can get very complicated.
