Recreate standby controlfile
Date: Tue, 1 Jul 2008 21:15:46 +1000 (EST)
I have a customer using Dataguard with ASM/OMF
Primary 8 node RAC on 10.2.0.3
Standby 8 node RAC on 10.2.0.3
When the files are restored as part of a duplicate database for standby command the file names generated are obviously different
On primary system datafile is system.476.639871213 whilst on standby the same file is restored as system.445.658666449
If for any reason the standby controlfile has to be subsequently recreated what is the fastest/most efficient way to rename all data files since the controlfile will have names from primary.
I could create a database link called dd to standby but I would have to open the standby in read only mode to generate commands from the below script
'alter database rename file'''||
prim.name||''' to '''||stdb.name||''';' from v$datafile prim, v$datafile_at_dd stdb where prim.file# = stdb.file#
Surely they must be a simpler way to do this given I have more than 500 datafiles.
