My 3.1.1 VM Manager installation which I tried to update to 3.2.1 is broken. I don't know if it's the OracleDB-backed OVS repository or the application itself, but it's broken. I'm waiting on Oracle to tell me how to fix it.
In the meantime I have four Oracle VM Servers. Two are at version 3.1.1 and running four guests each. Two are at version 3.2.1 (installed as 3.1.1 and yum updated) and have no guests yet. Each one is in its own pool. All of them have local repositories on them which contain VM guest disk images (in the case of the 3.1.1 boxes) and installation ISOs. Everything is local storage only. If I run up a new Oracle VM Manager (at version 3.2.1) with a whole new repository (probably a local MySQL in 3.2.1) DB and take ownership of the four VM Servers will I get everything 'back'? That is to say, will I see the pools they're in, their guests and their local repositories, etc.?
I'm running out of patience with Oracle to get my broken-by-update VM Manager working again but am worried that if I abandon it (and the OracleDB repository it was using) I'll lose vital things.
Can someone help me out, please?
Well, in the end I just moved the old Oracle VM Manager 3.1.1->3.2.1 failed installation to one side and installed a fresh 3.2.1 with a MySQL back end (so not reusing the OracleDB 'OVS' database either). I had to do some renaming of things from UUIDs to human-redable names again (required some trawling through "vm.cfg" for disk image and VM names) but otherwise it was just a case of gaining ownership of the VM Servers scanning physical disks and generally rediscovering things and stuff.
Annoying. But in the end at least I know my Manager installation is fresh and clean.
So it turns out you lose mappings between UUIDs and human-readable names for things like VM disk images, pool names, etc. But so long as you know what files to look for on the VM Servers themselves to see what's what it's not terribly hard.
Not that Oracle was any help in the end.
You should be able to use the info in the following doc to make a backup of that info in the event you upgrade again:
Oracle VM Manager 3.2.1 database Migration from Oracle RDBMS to or from MySQL (Doc ID 1522460.1)
I believe there was another note mentioned in 1351518.2 that provides more backup info.
