CRONTAB_RMAN

Question

Hi All,
  I need to take RMAN full backup by every Sunday night and Wednesday night . I have the netbackup script which will take the backup to media.
Question is:
1. We have 15 - backup scripts for 15 DB in that server , so if i configure crontab for backup do i need to give all 15 scripts one by one or (*) will work .
    ie) 00 20 * * 3,7 /app/oracle/rman/scripts/hot_db_<sid>.sh     instead of this if i give  :  00 20 * * 3,7 /app/oracle/rman/scripts/hot_db_*.sh then it will works fine or not ?
2. Already my backup will create .output file in the same location , do i need to give output file location in crontab using( > ) ?
3. Also please tell me is the above crontab timing is correct ? (3,7) for Wednesday and Sunday 8pm? so Sunday is 0(zero) or 7 ?
Thanks in Advance,

Answer 1

We have 15 - backup scripts for 15 DB in that server
Why ? do scripts do different things from each other ? If not so, why not a single script with SID as parameter ? something like
ps -ef  |  grep smon  |  grep -v grep  |  awk -F_ '{print $3}'  |  grep -v +  |  while read SID
do
        <your script> $SID
done
or you can create a file with SIDs, and
cat SIDLIST | while read SID
do
      <your script>  $SID
done
