RE: RMAN question on the copy of the controlfile under $ORACLE_HOME/dbs directory

I think these are controlled within RMAN - at least that's where I have typically configured the settings for them. If you issue the command:
RMAN> show all;
you'll see the below settings.
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO
'/backups/oradata/SID/ctrlfileWWT2_%F';
The default for AUTOBACKUP is typically "OFF" when a database is first registered with RMAN. If it's "ON", then you can specify where the control files go, as well as their format, in the second "AUTOBACKUP FORMAT" line - possibly $ORACLE_HOME/dbs is the default location if no other location is configured? For us, the previous c-files get deleted every night, so if you modified the location, they might get deleted automatically from $ORACLE_HOME/dbs after the next RMAN backups are run...

Subject: RMAN question on the copy of the controlfile under $ORACLE_HOME/dbs
directory
We are having c- files under the ORACLE_HOME/dbs directory on regular basis
and these are pretty big to fill up the filesystem.
-rw-rw---- 1 oracle oinstall 15564800 May 22 18:08
c-3963933903-20110522-03
-rw-rw---- 1 oracle oinstall 15564800 May 22 23:09
c-3963933903-20110522-04
Q1. Are these created by RMAN? Q2. How to stop these files being written to ORACLE_HOME/dbs directory? Q3. What will be the impact if we delete these files from ORACLE_HOME/dbsdirectory?
Q4. Why these c-* files are not generated under ORACLE_HOME/dbs directory for other ORACLE_HOME?
Appreciate your help in advance,
Ashoke
