presenting ASM disks from server in Prod datacentre to another server in DR
801904Aug 22 2012 — edited Aug 27 2012Hello everyone
The environment is * Oracle 11g R2 (11.2.0.3) on Oracle Linux 6.x UEK, X86-64-bit, Oracle Grid and ASM 11.2, note: that RAC and Data Guard are not used at present *
I have a Prod server with database located on 4 ASM Disk Groups (located on 10 ASM disks) and I have identical DR server (i.e. has the same Oracle/Linux software installed on both servers).
I have mirrored all Prod data centre ASM disks to the DR data centre and now I need to present those ASM disks all to the DR server and start up the database there for DR (read only, just to prove that DR works ok).
Is there any Oracle documentation or any Oracle white-papers on the correct process how to do this, step by step?
All database files in Prod server , including all datafiles, undo, tempfile, redo logs, FRA, archived logs, RMAN backups, spfile, controlfiles,etc are located on ASM and the Prod copies of all ASM disks/groups were taken consistently using SAN vendor disk snapshot technology.
Additional question - can this database be started on DR server with a different name and how? Can I start it up first in DR and them rename it after? or rename it prior to starting up in DR ?
Many thanks for any tips or doc pointers.
