Home -> Community -> Mailing Lists -> Oracle-L -> RE: General Question about RMAN verification procedures...
Chris,
I agree with Ron.
I use Rman to backup and delete the archive log files. My backup runs in
three steps;
Database Backup
Archive log Switch
Archive Log backups
Control file backups
This way if an archivelog file is needed during recovery, Rman knows about it and asks for it. Right now, if you ever need an archivelog file, you are screwed. And lets face it, who knows what Rman will ask for when it comes to recovery. I think you are taking a slight risk in your current approach.

Chris,
What would happen if the RMAN backup failed and the next step is executed?
The archlogs over 2 days old would be deleted?
You can have rman perform the archiveing of the archivelogs and delete them
after they are archived with a day reference like you have. I don't have my
manual handy right now but it is in the books as how to do it in 8i.

After realizing that I'm the only dba left standing at this company, I've
decided that our backup and recovery procedures need revisiting.
Specifically the way in which we verify our backups ran successfully each
night.
We currently have five 8.1.7.2 oltp's in archivelog mode that are backed up via RMAN using a recovery catalog, and four 9.2.0.4 warehouse/ods databases in noarchivelog mode that are backed up via RMAN using the individual control files.
I am confident in the recoverability of our backups*they've been tested several times*as long as they successfully complete. Currently I am emailed the full output of each backup script for each database. We use 2 separate scripts. 1 for oltp's and 1 for warehouse.
This is all fine and dandy but to really keep up with it all, that means scanning 9 backup logs each morning.
<whew!>
my question is this*for those of you using RMAN as your backup utility, how do you ensure your backups complete successfully and are valid? Do you query the catalog directly? Do you have a script that validates the backups? Do you have a single email with nice discreet output for each database? *.are you willing to share you scripts? *
*and while I'm at it. *can anyone poke any holes in the following scripts? *I know they aren't as elegant as some*but they work and have been tested.
OLTP:
#!/bin/sh
export ORACLE_HOME=/u01/app/oracle/product/8.1.7
export ORACLE_SID={DB SID}
export ARCH_DEST=/u01/app/oracle/admin/$ORACLE_SID/arch/
rm /oracle_backup/$ORACLE_SID/*
$ORACLE_HOME/bin/rman <<EOF
set dbid={db id*so no one can mess with the tnsnames and screw with out
backups*it is well know that the dba group will have to change this in the
event of some event that would change the dbid}
connect target
connect catalog username/password@{recovery catalog db}
run{
allocate channel d1 type disk;
backup database format '/oracle_backup/$ORACLE_SID/%U' include current
controlfile;
}
sql "alter system switch logfile";
sql "alter system archive log all";
sql "alter database backup controlfile to trace";
sql "alter database backup controlfile to
''/oracle_backup/$ORACLE_SID/prd1_ctl''";
exit;
EOF
#
find ${ARCH_DEST}*.arc -type f -mtime +2 | while read ARCH_LOG; do
echo "removing "$ARCH_LOG
rm $ARCH_LOG
done
Warehouse:
#!/bin/sh
export ORACLE_HOME=/u01/app/oracle/product/9.2.0
export ORACLE_SID=PWH1
rm /$ORACLE_SID/_backup/*
$ORACLE_HOME/bin/rman <<EOF
connect target /
shutdown immediate
startup mount
backup database;
alter database open;
sql 'alter database backup controlfile to trace';
exit; <<EOF
*.thanks for any help!!!
