Some question about cotrol file

Question

Hello,
ALTER DATABASE BACKUP CONTROLFILE TO TRACE
- in my case I have three control files. The above command will generate the SQL
command for regeneration of all three control files?
- is there any way to find in which trace file the SQL script will be written. In my user (udump) and database (bddump) dump directory are many trace files and it is hard to find it. Also it is safe to delete all this trace files?
- RMAN is kepping all it's data ( required for recovery) in control file.
By using the above command I didn't find nothing about those data ( in the trace file ) or maybe I skip it.
Windows 2000, Oracle 9i
Thank you!
Sorry for the two other threads started ( with the same subject) but there was a problem with my Internet connection, my page browser didn't update to indicate that the post have been saved.

Hi,
To get the file, use this select in the session where you executed the backup to trace:SELECT
     'The file you search is: ' ||
     DIR.VALUE || DECODE(SUBSTR(DIR.VALUE,1,1),'/','/','\') || '*' || SPID.VALUE || '*' "Info"
FROM
     (SELECT VALUE
      FROM V$PARAMETER
      WHERE NAME='user_dump_dest'
     ) DIR,
     (SELECT SPID VALUE
      FROM V$PROCESS
      WHERE ADDR=(SELECT PADDR
                FROM V$SESSION
                WHERE SID=(SELECT DISTINCT SID
                     FROM V$MYSTAT)
     ) SPID;You can cat/type this file directly. The file name returned uses wildcards (*) purposely.
I read something about RECOVERY CATALOG and found that it can be created on same database or in a different database:Yes.
If it's created in same database and this is lost, RECOVERY CATALOG will not be lost too ?Yes, it will. That's why we create the RECOVERY CATALOG in a dedicated database (for example the one in which EM Grid Control / OMS has it's repository.
- If it's created in a different database, do I need a RECOVERY CATALOG for this database too? Well, you can do like that. I don't do it though. My RMAN's RECOVERY CATALOG database is backed up online via standard archivelog method (with my dynamic backup script), not using RMAN.
