Oracle RAC newbie

I am newbie to RAC. some very basic questions

let's say we have a two nodes RAC, does it means

• Two system tablespaces -Two Temp tablespaces
• Redo logs for each instance in its own disk
• The only thing is shared are User Datafiles and they must be in SAN
• What has to be in both init.ora minimun?
• Database create command is difference or not? Can you send me the script as sample?
• When I connect from sqlplus from another PC what exactly happen?

_ what is differenne in listenetr.ora and =tnsnames?

• AS soon as one node crash what happens?
• Who do the load balance?
• How do you value RAC to Hot Standby honestly?

Sorry too much questions but shed a brief light give me idea. Thanks millions Received on Sun Aug 06 2006 - 13:51:01 CDT
