You must complain about why ORACLE does not have archive maintenance tools.

Log in to the database server host as an ORACLE user or. The last step was to run delete obsolete in RMAN and see that the old archive log backups are getting deleted. For the primary after an schedule backup is done, I just keep 1 backup set then purge the old ones immediately using : But this does not work on standby db right? The Next was another MOS search that lead me to bug 29056767. Just imagine if you delete the archive log, Still use delete archivelog all completed before'sysdate-N'.

As I said, I run the RMAN backups on the standby side, while the script executes delete obsolete after the backup (retention is configured to redundancy 2). On this environment, after the upgrade I saw that RMAN keeps a few backup files (not all) of every backup for much longer (at the time I looked it was 2 weeks, and it didnt seem to delete these files at all). Of course, after deleting these physical files under the OS, the. Then I thought maybe there is an issue with the delete obsolete command, so I decided to check what RMAN thinks about the restore process. 7 Use list expired to see if there is an invalid archive log, and prove that there is no invalid archive log: RMAN> list expired archivelog all; it does, not match any archive log in the recovery directory.

I listed them (list backuppiece in RMAN to see the backupset, then list backupset to see the content), all of them were archive logs. The environment has a single instance primary database (with GI+ASM) and a single instance standby database (with GI+ASM) and we run backups on the standby database only (to reduce load from the primary). , it can delete archives and FLASHBACK correctly, but remember, ORACLE archive log is very important for ORACLE data recovery and backup, do not delete archive log as a last resort. 2. rman target sys/@<standbydb> <

LossRecoveryAppliance,commonlyknownasRecoveryAppliance." I do not know which command will auto delete it after applying to the standby. protected-databaseside,nottheRA,obviously)? In an environment Ive upgraded lately from 11.2 to 18c I found out that some backups are not getting deleted from the standby database. I have tried that but it does not delete any? IguessI'mhavingtrustissues. I do not know what type of dataguard they have setup. If this does not work, then you can try deleting them by checking the sequence that was last applied and delete until that sequence using RMAN.

After that I checked and saw that the SCN was getting updated. It doesnt make sense. A file with old SCN requires Oracle to apply all archive logs from that SCN onward. 6 Try to synchronize, see if it works, the result does not work, and the crosscheck still fails: Archive log file name=D:ORACLEORADATATESTARCHIVE1_47.DBF record ID=1 Timestamp=572866, Archive log file name=D:ORACLEORADATATESTARCHIVE11_48.DBF record ID=2 Timestamp=57286.

All rights reserved. DELETEOBSOLETEcommandcannotbeusedwhenbackupsarestoredtoZeroData So did you figure out what was causing this?

The SCN of all the files was the same, but when I compared that to the primary I realized that the SCN of the standby files is much older than the one of the primary files.

Dave, Archivelog deletion w/ ZDLRA - Herring, Dave. If you have never done this action before, we can compare the size of the controlfile before and after the action! Are there different kinds of dataguard setup? It is a small appliance with not a lot of disk space and, Many Oracle databases are running on Linux/UNIX systems, and many DBAs need to write all kind of scripts. I just realized that I havent blogged about it (even though I, Industrial WordPress Theme Liron Amitzi, GotoDBA.com, 2019. somethinglike"DELETEUNTILSYSDATE-1"andhopethatRMANwouldraisean" archivelogall;". 4. we facing this after upgrade database from 10.2.0.5 to 12.1.0,2 rman did not deleted archive log backup along with incremental backups. After this deletion, it is best to perform a full backup of the database immediately, The archived data 7 days ago can be found through FIND and deleted using the EXEC sub-operation. Are the backups configured on standby DB or on primary DB ? SBT_TAPE; does not think that these logs have been deleted, so when deleting archivelog, we need to do some settings in other places.

I do not know also if this is the rman backup from primary thet is being file transferred to the dr server. Archivelog cannot be directly physically deleted from the OS layer, because the relevant information of archivelog is recorded in the controlfile, and the settings of the controlfile will not be changed after the physical deletion. ORACLE correct way to delete archives and reclaim space.

At first I went to the basic idea that something has changed or is broken in 18c RMAN. 3. For example, to enable APPLIED ON STANDBY: RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY; CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY; new RMAN configuration parameters are successfully stored. Is there a command in RMAN for standby db which list the old archivelogs that has been applied and can be deleted? You can schedule a script that would delete the archives on the standby.

If the SCN of the files is old, the recovery process will restore these files with the old SCN and will require all archive logs from this SCN forward, even if there is a full backup of the files from a later time. can use RMAN to remove ARCHIVELOG, specifically the following steps: corresponding archivelog record cannot be found in the. Your email address will not be published.

I set the parameter on the standby database (alter system set _time_based_rcv_ckpt_target=0;) and restarted the redo apply (using dgmgrl: edit database set state=apply-off, then: edit database set state=apply-on). Now it all makes sense. I am just confused with my standby db.

you must create a script to delete old archivelog on standby. For example: allocate channel for maintenance device type disk; delete archivelog until time 'sysdate - 7' ; $ORACLE_HOME/bin/rman target / catalog user/[emailprotected] << EOF. The next step was to see what these backup pieces actually were.

However, the user can still manually delete it by DELETE ARCHIVELOG. backupofarchivelogall;". In versions after 10g, Oracle has added an archive file deletion strategy in RMAN. Do I need to invoke rman backup at standby so that I can auto delete expired backups? delete force noprompt archivelog all completed before 'SYSDATE-4'; This would delete all the archives before SYSDATE-4. In this case I need to remove this by my own script? This bug is for 18c and causes the datafile checkpoint information not to be updated in the standby database. I have a full backup of all files from 2 days ago, but Oracle still needs archives from 2 weeks ago. And when querying related dynamic views (such as v$archived_log), this part of the log is still marked as existing. Required fields are marked *.

I used restore database preview in RMAN to see which backup files RMAN wants to restore and realized that RMAN actually needs the archive logs in these files to restore the database. Is this the expected behavior in 12.1 or some kind of a bug? Your email address will not be published. it is a bug, then only Set deletion at the OS layer, or force deletion with RMAN.
