Chirag, I tried to be nice and tell you to read some papers in a nice way. It is, however, still Monday and I can reformulate my kind advice: go and read the fine manuals on Tahiti. Good luck. There are no stupid questions, that much is true. You definitely don't want to hear the rest. Please, do not insult me by not doing your homework and asking trivial questions which can be readily answered by 10 minutes of reading white papers. Another occurrence of this same question will be understood as an invitation for practicing acidic form of humor. If I read the manual, so can you. If you can't then give notice and relinquish your position to someone more willing to do some reading. Have a nice day. -- Mladen Gogala Ext. 121 _____ From: Chirag DBA [mailto:chiragdba@xxxxxxxxx] Sent: Monday, October 03, 2005 12:00 PM To: Gogala, Mladen Cc: Oracle-L Freelists; askdba@xxxxxxxxxxxxx Subject: Re: Wanna implement RAC. Thanx a lot Dear Santa. Get ready for CHRISTMAS too. ;) As you said, let me go through this site and all the manuals. But I have one question in mind. HOW RAC HELPS FOR HIGHER AVAILABILITY?
