We are having an intermittent problem related to failing RMAN archive log backups. Normally everything works fine but once every fortnight or so the archive log backup starts to fail with the below message. We run two Oracle instances on this windows box, so they are using same oracle and TSM client binaries, but it is only of the instances that have this problem - the largest instance though. Restarting the Oracle instance solves the problem and everything is back to normal, until next time ...
This is the error message in the rman log file

I have the incident file as well if that is of any use.
Could the problem be related to running two backups in parallel?
We run full backups once a week and both this time and last time the archive log backup failed it was in conjunction to when the full backup also was running.
Is there any other solution to the problem than restarting the oracle instance?
Since this is a busy production instance it is a big problem for us to restart it outside of maintenance windows.
I had a production db with archive logging enabled
SQL> select name,status 2 from v$archived_log;

So i need to restore archivelogs by using sequence
RMAN>RESTORE ARCHIVELOG FROM SEQUENCE 20 UNTIL SEQUENCE 28; So the restore is completed successfully So its very hard to monitor archivelog files i feel i should have included all archivelog files while taking RMAN backup
RMAN >backup database plus archivelog all delete input;
but the problem is my RMAN backup is already 360GB in size and it takes 4-5 hrs to complete .so i need to schedule RMAN backup at one time (e.g sunday) ,delete the archivelog files older than sundayand now schedule the archivelog backup at another day (e.g wed &sat)
my question is where i have to change my script to backup all avaialbe archivelog files if old archivelog files are deleted at os level?
RMAN> run { 2> allocate channel c1 type disk; 3> sql 'alter system archive log current'; 4> backup archivelog all format 'D:oracleackuplog_t%t_s%s_p%p' delete input; 5> release channel c1; 6> }
We are going to implement oracle 11g. Now I wanna use rman to take the incremental backup in the follwing way:
Level-0 backup weekly, in the way:
run { allocate channel c1 type disk; allocate channel c2 type disk; BACKUP incremental level 0 DATABASE TAG 'Weekly_full' FORMAT 'E:RMAN_backupweekly_full_%d_%Y%M%D_s%s_p%p.bak'; backup archivelog all not backed up 1 times delete input TAG 'Weekly_full_arc' FORMAT 'E:RMAN_backupweekly_full_arc_%d_%Y%M%D_s%s_p%p.bak';
[code].....
and RETENTION POLICY TO RECOVERY WINDOW is set to 10 days, so that there is no chance that i will delete expired backup before taking backup.
Now my question is,
1) Is the way is correct that there is no wrong configuration. My main concern is about archive log, is it correct?
2) As i am deleting archive log files with the backup and after that the expired archive log backup is also deleted, so is there any chance of failure in recovery.
3) here how archive log backup will work with 10 days retention policy.
I trying to backup archive logs using rman in standby database. I'm able to backup archive logs using simple command it get's successfully completed. rman > BACKUP ARCHIVELOG ALL When i'm trying to do with keep command it's getting failed.I'm trying to do on physical standby databaseBACKUP ARCHIVELOG ALL KEEP UNTIL TIME 'SYSDATE+100' TAG = 'TEST'.
We have a nightly rman backup that was complete and clean.The backup contains a Data File, Control File and a backup Archive Log file.The database server crashed with all the subsequent archive logs lost.
We are trying to recover from the three backup files.We are bumping into the backup piece missing as all the archive logs are done. how to restore with the exising backup files. the lost archive logs are probably salvageable.
If I want to take Rman archive log backup with delete input command , how the archive logs will be copied to standby database
For eg
I am taking archive backup as
RMAN>backup archivelog all delete input;
here consider few archives are not copied to standby database (due to nw issue) then how standby will receives these missing archives as those are deleted by rman backup at primary side.
I am not getting any document related to above query.
Is there any way I can get all the archive log files present in a backup piece. I tried following but it always gives me all the log files for each piece:
**** SQL> select s.set_stamp, s.set_count, s.PIECES, s.backup_type, s.controlfile_included from v$backup_set s, v$backup_piece p where s.set_stamp=p.set_stamp and s.set_count=p.set_count and p.handle='5mjv4do0_1_1';
Actually, i have test database open in read only and i want to apply archive files carry from production database at daily level. When i'm going for recovery, since database is already in consistent state, it is not asking for recovery.
There is a archive log backupset,and the backup set contains many archive log file,and now i want extract to a directory,how can i do?

There is an incident that in production database 1000 archive log files generated.From 1000 files, 100 archive log files have been removed.When i take incremental backup next day , what will happen in database?
How after a re-catalog of an archivelog, RMAN knows that the archivelog will be needed and in the right order?
If the re-catalog and subsequent crosscheck has changed the path of the archivelog will RMAN ignore the path and just recognize the archivelog name and format?

I am trying to remove archive log file on my standby site but I am getting the following message. There are lots of archive logs are present on the storage but rman is unable to displaying that.
RMAN> list archivelog all;

I have 2 seperate rman backup one backup is of only datafile ,spfile and controlfile which i am able to restore and recover without any problem say bkp1 taken at 10 am
other set of backup is of only archive log files of same day but later time than datafile backup say bkp2 taken at 8pm...if i restore and recover bkp1 and try to restore bkp2 it gives error datafile exist (possibly due to fact both backup have control file)
if i just restore bkp1 and try to restore bkp2 so that i can do one recover at time it gives error datafile permission issue (possibly due to fact both backup have control file)
I want to restore database upto 8pm time how can i use both bkp1 and bkp2 to do it(restore datafiles and apply all archive logs on it)
I have Oracle 10gR2 database on a windows server, I have scheduled rman backup for this database from Solaris server
set echo onrun { crosscheck archivelog all; backup check logical database plus archivelog; delete noprompt obsolete device type DISK; } exit;
It is deleting the obsolete backup pieces but it is not deleting old archive logs (obsolete archive logs) and it is not even showing old archives as obsolete when I check thru report obsolete
I am running the following command to backup my archive logs and want to keep at least two hours of .arc files on disk.
rman < connect target login/password connect catalog login/password show all; sql "alter system archive log current"; backup filesperset 5 archivelog until time 'sysdate-2/24' format $FILE_DEST_ARCH delete input ; resync catalog; EOT
On some occassions, there will not be any archive logs that meet this criteria and I get the following error:

Is there anything I can do to the rman command above that will prevent this error from happening but yet keeping same functionality?

We are doing RMAN Duplicate set until time to refresh daily our test database for our developers and it taking long time to finish. We noticed on the restore log that RMAN was using a day old old backup pieces to refresh the test database and don't immediately use the latest backup pieces instead.
For additional details here's the rman duplicate command we are using which we run daily(mon-sat) at 4am once daily full backup on production completed.
RMAN Duplicate commands: run { set until time "to_date(to_char(sysdate,'Mon DD YYYY') || ' 04:00:00', 'Mon DD YYYY HH24:MI:SS')"; allocate auxiliary channel ch1 type disk; duplicate target database to testdb; } exit
Is there a way on how to let RMAN use the latest backup pieces instead?
I am tryign to run a split onlike full backup from the os useign the sap command which is linked to rman..Command that i am useing is ...
