Qaiser, Did you contact Support, or Sales, for that answer? :-) Admittedly, running non-RAC on a Veritas clustered file-system is unusual (i.e. falls into the "why would you do this?" department), but I can't see why it can't be supported. Except for all the bells and whistles and complications and overhead of a clustered file-system, it's just a file-system, right? You'll need to get rid of all but the first of your threads of redo. An "ALTER DATABASE DROP LOGFILE THREAD" command should help here. Just don't drop thread #1, please. Optionally, you might also want to get rid all but one of your UNDO tablespaces (or all but one of your RBS tablespaces if UNDO_MANAGEMENT=MANUAL), though you don't have to do this. It's just a good idea to reclaim some space. Then, you'll want to get rid of the RAC layer of code by relinking without it. Someone else might want to help here (as I don't have a RAC system handy), but the make script for linking the executables should have a RAC or no-RAC flag somewhere. Finally, make sure that the parameter CLUSTER_DATABASE defaults to FALSE in your remaining database instance. I don't know if the OUI will allow the deinstall of the RAC option (which is probably what the support person was talking about), but you could just reinstall everything without it, I suppose. Although, if the OUI keeps detecting "/dev/odm" then it will just keep reinstalling RAC. So, you might have to ask Veritas how to de-install the cluster, which will probably yield the same answer as from Oracle... :-) Or move the database to a non-clustered server... Oh, did I say to back everything up (i.e. database and ORACLE_BASE) before you start this? I meant to... Hope this helps... -Tim P.S. When all this is done, do you get to pocket the license fees that Oracle returns? I'm going to expect a cut... on 8/30/04 5:31 PM, Q A I S E R at qrasheed@xxxxxxxxx wrote: > - 9.2.0.5 64bit > - RAC > - Solaris 8 > - VERITAS DBE?AC 3.5 > > Does anybody on the list has any experience converting a RAC database > to a single instance Database in Cluster File System configuration? > > I was able to find a Doc. on metalink with step by step instructions > on "How to convert a single instance Database to RAC", but not the > other way round.
