You can run onclean command to ensure a clean environment. This will cl= ean up any shared memory segments that are required by the server, but migh= t be left over.

Jonathon Wyza Response: Well, you could try to bring it up with oninit -v to possibly get a better idea where the server failed as it was trying to come online. From the online log, it looks as thought it was about to, or did complete logical recovery, and I believe at that point, it would have tried to do a checkpoint and flush the reserve pages to disk. It's possible that's where it's failing. If you want this server up, you are likely going to have to engage tech support. I wouldn't think you are crashing into some other shared memory, as I believe by this point, that should all be done, as it appears the server was trying to do the recovery portion of coming online. You might try and run oncheck -pr/-cr and when doing a -pr look for maybe disabled dbspaces or down chunks, however, I would have thought if you hit a down chunk/disabled dbspace there would be better messages in the online.log, unless maybe its the root chunk.

Did your Systems Administrator allocate enough Shared Memory for this server?
