Have you looked at the 9.2 documentation ( RAC Administration guide )?

Chapter 4 "Administering RAC Databasers with the Server Control Utility" which also covers srvconfig?

Basically ( from my hpux centric point of view shouldn't be too far from linux rac I imagine but caveat emptor ) after you have successfully defined a raw partition in a logical volume manager ( varies by os ) and you have /var/opt/oracle/srvConfig.loc ( file varies by os ) pointing to the raw parition you have to do the following when you create a RAC db

srvconfig -init then gsdctl start then dbca etc or do it step by step

You can then "back it up" by srvconfig -exp filename ( whether raw or on a clustered system I guess ) and you can restore it by srvconfig - imp ...

If you lose it entirely and don't have a backup ( try this on a test system not production please ) you should be able to knock everything down ( including gsd etc ), get your raw partition "useable again" ( whatever that means ), initialize it again via srvconfig - init then start up gsd ( not the database yet ) and populate it ( srvctl add database and srvctl add instances ), start up listeners and oracle etc.

But again please don't just believe me work your way thru appropriate sections in the RAC admin guide and plan out the testing you need to do on a test system. Received on Fri Jun 29 2007 - 09:10:56 CDT
