RHEL cluster instead of RAC
Hi people. I asked this question on Generic Linux and Database General topics, but I didn't get an answer. So..
We had an Oracle 11R2 database RAC installed on two nodes and recently we "migrate" to Oracle 11R2 RHEL cluster. As I can see, it's not an online cluster like RAC, but is cheaper and if you don't need super cluster availability, it's ok solution.
The problem is, I don't now how to exactly restart, shutdown and start IS, mean database. If one node fail, other will see that and take all new connections. So, if I assumed correctly, if I say shutdown immediate (or any shutdown ), 2nd node will take connections. Shutdown both or turning off nodes is not nice option.
What will I get if I choose restart, stop/start this cluster trough web interface of luci server?
I saw a interresting command clusvcadm to enable, disable, stop "group" or lock and unlock resource group manager etc, but I cannot find good explanation related to Oracle database.
Can someone, who has system like me, tell me the procedure of stopping and starting this kind of system?
Thank you very much,
Miroslav
