Backup & Recovery :: How To Get All Archive Logs In Backup Piece

Nov 8, 2008

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';

Backup & Recovery :: RMAN Hot Backup Plus Archive Log Files?

Jan 11, 2008

I had a production db with archive logging enabled

SQL> select name,status
2 from v$archived_log;

NAME STATUS
---------------------------------------- -
D:ORACLEARCHIVE_ORCL11_13.DBF A
D:ORACLEARCHIVE_ORCL11_14.DBF A
D:ORACLEARCHIVE_ORCL11_15.DBF A

[code]...

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> }

Backup & Recovery :: Change Archive Log Mode During DB Running?

Aug 24, 2011

changing archive mode during DB running.Before in 9.2, 'ALTER SYSTEM ARCHIVE LOG START/STOP' is available for this job. But, after 10g/11g, it cause 'archive log stop has been deprecated'.

However, for my practice, I need to estimate archived logs size before backup them, so I need to stop archive log for a while and enable it later during DB running.

I check Oracle documents, it only mentions changing archive log mode at DB mounted but not open.

Backup & Recovery :: 2 Separate RMAN Backup One Backup Is Of Only Datafile

Jan 24, 2011

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)

Backup & Recovery :: RMAN Recovery Failing With Incremental Level 0 Backup

Feb 10, 2011

We are trying to restore a database on the different server using RAM incremental level 0 and 1 backups. We have weekly Incremental level 0 backups along with incremental backups on daily basis. During recovery of Incremental level 0 backup, RMAN is expecting/looking for Incremental Level 0 backup of prior week as well. Is this the usual process for RMAN to look for prior level 0 backup though we need to restore from the current level 0 backup and roll forward by a week with subsequent Level 1 backup.?

We intend to restore from the Level 0 of 1/16 and roll forward with daily incrementals till 1/22. RMAN is expecting level 0 backupsets from 1/9 backup as well and keep failing since those backups are not available. quick inputs since we are in middle of recovery and trying to resolve if this is even doable.

Backup & Recovery :: RMAN Backup Deleted Even Within Recovery Window

Oct 18, 2011

I have problem on using "delete obsolete" in RMAN.

First, let describe my backup configuration.

1. Full backup every Monday (17-Oct, 10-Oct, 3-Oct, 26-Sep)
2. Incremental backup for other days
3. Enable autobackup of control file
4. Backup archive log every day
5. RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS
6. Execute "Delete obsolete" every day
7. control file is used instead of catalog

The results observed:
1. Backup of control files older than 30 days will be deleted
2. Backup of archive log files older than 30 days will be deleted.
3. Backup of datafiles older than ~14 days but before 30 days are also DELETED.

In my example, the backup of datafiles created at 26-Sep is deleted at 16-Oct.

I tried "restore database validate until time "sysdate-22"" at 17-Oct. And RMAN reported "datafile xx will be created automatically during restore operation". It seems that RMAN failed to do restoration up to 22 days ago. The retention policy I set seems not effective on datafile backups.

I checked view v$backup_set and the "Keep" is "No" and "Keep until" is empty.

The only thing I can think of, is the settings of "CONTROL_FILE_RECORD_KEEP_TIME". It is marked "7" in the Oracle, which is less than the retention. But I suppose this only causes the backup not deleted, but NOT be deleted earlier.

Backup & Recovery :: RMAN Duplicate Set Until Time Using Wrong Backup Piece Name To Restore?

Feb 26, 2012

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?

Backup & Recovery :: ORA-19870 / Error Reading Backup Piece During Database Cloning

Mar 15, 2011

I am trying to clone a database on another server with different direcory structure. So that path on the source db server are /u04 whereas on on target db server it would be /u03.

Since this I am testing it on small database initially I have kept all datafiles, backup and archivelogs at /u04 and /u03 on the source and target db servers respectively Now I have copied the backups from source db server to target and since path is changed, I cataloged it

However during restore I am getting

Backup & Recovery :: Backing Up / Restoring Oracle Database Via Entire Backup Of Server

Aug 7, 2012

I've read a lot about the different types of backup available with Oracle (hot and cold backup). However, I was thinking of a different way of performing this task. I'm currently using Windows Server 2008 R2 and Oracle 11g Standard Edition. I'd like to schedule an entire backup of my server via the utility "Windows Server Backup" (available for free).That way, I could recover my entire server with all the programs and files in case the latter crashes.I'm wondering if this solution could be used as a way of backing up (and recovering) the Oracle database. Should I still set up a regular hot backup with the Archivelog mode enabled in case some operations/transactions were being done at the time of the crash (for the data integrity)?
