Thanks Zhu for the info & replies Some Questions are IN CAPITALS BELOW:- ________________________________ From: Zhu,Chao [mailto:zhuchao@xxxxxxxxx] Sent: Thursday, August 31, 2006 2:08 PM To: VIVEK_SHARMA Cc: oracle-l@xxxxxxxxxxxxx Subject: Re: Veritas CFS or QFS ? Which for High Hybrid Transaction Load Benchmark on RAC with Solaris 10/Oracle 10g ? Simply use rman to restore your datafiles to raw volumes. OK The most min-downtime solution is; build a standby on the raw volume on rac, do a switch over, and your databsae is running in rac mode within 10 minutes. THERE ARE NO TIME CONSTRAINTS AS NO PRODUCTION DATABASE IS INVOLVED. THE AIM IS TO CHECK THE POSSIBILITY OF CONVERTING A BIG BENCHMARK DATABASE CURRENTLY EXISTING ON A MOUNTED "UFS" FILESYSTEM "TO" RAW DEVICES WITHOUT USING EXPORT/IMPORT & RMAN. You can take anytime you desire to make your standby database onto the raw volume. IS IT POSSIBLE IN SOME MANNER TO COPY THE DATAFILES FROM THE SOURCE DATABASE EXISTING ON MOUNTED "UFS" FILESYSTEM PARTITIONS "TO" THE TARGET DATABASE EXISTING ON PRE-CREATED RAW DEVICES FOR THE 1st TIME FOR THE CREATION OF THE STANDBY DATABASE? CAN "dd" COMMAND BE USED?

Is there any option Other then export from mounted Database & import into RAW Database? Hence RAW is being avoided for now.

Dealing with veritas volume manager, it does not make much difference between creating a datafile on filesystem, and creating a datafile on a volume **************** CAUTION - Disclaimer ***************** This e-mail contains PRIVILEGED AND CONFIDENTIAL INFORMATION intended solely for the use of the addressee(s).
