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/dbs directory?
Q4. Why these c-* files are not generated under ORACLE_HOME/dbs directory for other ORACLE_HOME?

Appreciate your help in advance,
Ashoke
