Hi Experts,
Can I give different backup location for backups sets and archive logs with format caomand in the same script.
Currently my RMAN Comand is:-
run {
allocate channel chan1 type disk format '/data2/orabackup/BHI_1/rman/0/%d%U
.rman0';
set limit channel chan1 kbytes=2000000;
backup as compressed backupset incremental level 0 filesperset 1 database;
sql 'alter system switch logfile';
backup archivelog all;
backup current controlfile tag = 'BHI_1-ctl'format = '/data2/orabackup/BHI_
1/rman/0/ctl_%d_%U';
restore database validate check logical;
crosscheck backup;
crosscheck archivelog all;
delete noprompt archivelog all completed before 'sysdate-4' backed up 1 ti
mes to device type disk;
delete noprompt expired backup;
delete noprompt obsolete backup;
# delete noprompt expired archivelog all;
release channel chan1;
}
According to current policy all the backups are getting stored
into '/data2/orabackup/BHI_1/rman/0/%d%U.rman0'
I want archive logs to be stored at different disk due to space
issues on disk /data2.
How can I acheive this in the same script.
Regards,
Varun Punj

Hi Michel,
I have changed the backup plan as suggested by you by allocating three channels.The new backup plan is:-
run {
allocate channel chan1 type disk format '/data3/orabackup/BHI_1/rman/0/%d%U
.rman0';
allocate channel chan2 type disk format '/data2/orabackup/BHI_1/rman/0/%d%U
.rman0';
allocate channel chan3 type disk format '/data4/orabackup/BHI_1/rman/0/%d%U
.rman0';
set limit channel chan1 kbytes=2000000;
set limit channel chan2 kbytes=2000000;
set limit channel chan3 kbytes=2000000;
backup as compressed backupset incremental level 0 filesperset 1 database;
sql 'alter system switch logfile';
backup archivelog all not backed up 1 times;
backup current controlfile tag = 'BHI_1-ctl' format = '/data2/orabackup/BHI
_1/rman/0/ctl_%d_%U';
restore database validate check logical;
delete noprompt archivelog all completed before 'sysdate-4' backed up 1 tim
es to device type disk;
crosscheck backup;
crosscheck archivelog all;
delete noprompt expired backup;
delete noprompt obsolete;
release channel chan1;
release channel chan2;
release channel chan3;
}
Redundancy is set to recovery window of 1 day.
I have one question now.With this backup plan I should be able
to keep 4 days old archive logs on the disk as I am giving
delete noprompt archivelog all completed before 'sysdate-4' backed up 1 times to device type disk.
But I cannot see archive logs older than 2 days on the disk.
Is there anything I am missunderstood.Can You please let me
know what change I can make to keep the archive logs for four
days at the disk on the achive_log_dest location.
Regards,
Varun Punj

Thanks for your reply.I have one more question:-
Is this policy appropriate for stream environment.
Delete Obsolete wont delete if stream needs the required
archive logs.I can not test it because it is production
environment.Please tell me If I my statement is wrong.
