I am trying to learn about RMAN Incrementally Updated Backups. I created a database on Server A with the parameters and configurations as shown in image attached. I would like to restore full database on Server B (Test DB).The Server B is exactly same in directory structure as the Server A
e.g. ('E:archive','E:incr_backup'). I would like to automate this process so that it updates the Server B on daily basis for R&D purpose.
I run DLY cold backups including controlfile & archivelogs and keep 3 gens of backups and archivelogs to 3 days also. What is the correct procedure to restore back to an old cold backup. Database is backed up Mon,Tue,Wed on Thur we require to bring database back to Tuesday DLY security.
I have tried: startup mount restore database from tag 'DLYTUE' recover database
( this just rolls forward on all archive logs once it restores datafiles, not getting to point to alter database open resetlogs.)
Next tried to :
recover database archivelog tag 'DLYTUE' ( same outcome )
What is the correct rman procedure including should I remove old archive logs from working OS directory ? Also need to know once I restore back and open database to TUE security how do you tidy up the archive logs and dumps which are no longer require i.e. : weds..
I have read about using the set until time option but how to I get absolute time from when cold backup completed if this is the correct procedure.
RMAN is not removing obsolete backups and now the backup directory is nearly full.Retention policy is 1, however, there are backups more than 6 weeks old still in the backup directory.crosscheck and delete obsolete commands run every night, and I have also run these manually, yet the backup files still remain.It is like RMAN is not aware of their existance.How can I confirm that RMAN does not need them and therefore delete them manually using OS commands.
I have taken the RMAN Full database backup through the following command.My database is in no archivelog mode.
AT RMAN prompt Shutdown immediate; Startup mount; run { allocate channel c01 device type disk format 'd: man_bkp est_%U'; allocate channel c02 device type disk format 'd: man_bkp est_%U'; backup full database tag 'full_bkup_test_081111'; backup current controlfile; backup spfile; release channel c01; release channel c02; }
Now i have deleted my all controlfile and spfile/Pfile from the database.So how can i recover my SPfile and controlfile? i do not have autobackup on of SPfile/Controlfile.
I have a live server on which Oracle 10g Database is running. We take full RMAN Backups everyday. Now we want to restore the RMAN Backup file from the Live server to another machine (which is going to be a test system). I want to restore the latest RMAN backup on the test machine (which is not on network).
When I copy the RMAN backup set in the flash recovery area of the test machine and then use "list backup", the backup set is not listed. I also tried "crosscheck backup" and then "list backup" but still the backup set does not appear. how can I register the backup set from live server into test machine and then restore it.
I have a problem in running delete obsolete or report obsolete using rman. Although the retention policy is set to "CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 60 DAYS;", when running delete obsolete or report obsolete it deletes or returns all the backupsets till sysdate. What should I do to solve this issue?
is it possible to have a vss snapshot backup on the top of an RMAN backup. Because the link [URL] says that we can have an incremental level 1 backup on the vss snapshot backup.
So I need to know if interoperability between RMAN and VSS exists or not.
Also is it possible to have mixed backups meaning vss snapshot backups and rman backups. Whenever we take snapshot backup, is it updated in the control file?
Oracle 10gR2 on 64-bit RHEL.Backup Strategy:There will be a level-0 backup of the database every Sunday and level-1 every weekday.Archivelogs will be backed up up every 30 minutes.
Q: How can I delete ALL the archivelog backups that were taken that day (every 30 minutes) right after successful completion of level-0 or level-1 backup?
I want to delete them because they may not be of any use after the level-0 or level-1 backup (am I right)?
We observed that our RMAN backup was taking more time to complete. CROSSCHECK is the main culprit as because of having data in the catalog for more than 3 years.
So in the part of script we added delte obsolete recovery windoe of 14 days. (Redundancey 1).
Here the problem is we are getting error as
RMAN-03002 - failure of delete command RMAN-06091 - NO channel allocated for maintenance (of an appropriate type).
Reason: Till 2 years back the backup was stored in tape and after that it got changed to disk. So allocating channel disk to delete obsolet is not working. How we can over come this.
We tried like allocating channel tape sbt_type. It got failed as no media manager information configured. We dont have that information.
I am going through the Oracle VSS writer , trying out various methods. Just keen to know if this is the right place to ask VSS related questions as I could not find any post related to VSS.
For Volume based VSS shadow copy backups for a logged database, I am unsure about the restore method using VSS writer. Also oracle doc does not mention any steps for volume based restore of a logged (archive log mode db) database.
I've done a crosscheck backup in RMAN and the list of expired objects has actually gone down, in number, from the last time I did this ( 2 weeks prior). We do NOT delete anything from our RMAN catalog on a routine basis (ie. no "DELETE EXPIRED BACKUP commands were issued) so normally the list of expired backup objects increases with each RMAN maintenance task we do. Why the number of expired objects might actually go down in this particular instance ?
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.
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.
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)
While connecting to target database from stand database. I am getting below error.

Backup-Based Duplication Without a Target and a Recovery Catalog Connection?
I have a doubt regarding the process the RMAN follows for restore and recovery of the database.
My Level 0 full backup completes on Saturdays at around 11 am after taking 8 hours (It starts at 3am).On Sunday, I ask RMAN to restore (on a different box) till Saturday 11:30 am.Then, after the restore is successful, I recover it till 11:45 am.
The recovery also goes fine and Iam able to clone to test box.
Till what time is the database restored? I assume its till 11 am since the L0 backup finishes at 11 am though I have asked it to restore till 11:30 am
During the recovery, ONLY the archives generated between Saturday 3 am and till the time i asked for recovery (Saturday 11:45 am ) are required. But, checking the recovery log file, i was surprised to see that RMAN has restored archive files starting from Friday 9:30 pm (Much before the time the Level 0 backup even started).
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 ...
brbackup -u / -c force -t online_split -m full -p initBR1_onlinefull.sap
The backup goes thru but i get this erro on the end...

Is this script is enough to delete the backup pieces older than 2 days.
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 2 DAYS; configure device type disk parallelism 1 backup type to compressed backupset;
run { allocate channel d1 type disk ; backup filesperset 5 format '/u06/backup/EBSDEV/EBSDEV_data_t%t_s%s_p%p' database ; sql 'alter system archive log current' ; backup filesperset 20 format '/u06/backup/EBSDV3/EBSDV3_arch_t%t_s%s_p%p' archivelog all delete input ;
