I have Oracle Database 11g Release 11.2.0.3.0 - 64bit Production With the Real Application Clusters and Automatic Storage Management. OS is Windows server 2008. Database size is approx 273 GB. I am running RMAN full back from a node with archive log all. With only 1 channel. Total backup size is almost 230 GB.
It is taking about 2 hours to complete the backup in the evening, but when i take same backup at midnight its takes about 1:15 hrs.
I'm on a Windows server 2003 R2 64 bit, database is 11.1.0.7. From RMAN connected to the target and the catalog, this is a show all;
RMAN> show all;
RMAN configuration parameters for database with db_unique_name ORCL are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 3 DAYS; CONFIGURE BACKUP OPTIMIZATION OFF; CONFIGURE DEFAULT DEVICE TYPE TO DISK; CONFIGURE CONTROLFILE AUTOBACKUP ON; CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'F:oracleadmin
[code]....
I'm running incremental backups, a level 0 on sunday and a level 1 the other days of the week, this is the ctl file:
LEVEL 0: connect target /@ORCL connect catalog rman/rmanpw@rmancat RUN {
[code]....
The level 0 does delete the archive logs (because of the delete input). Each backupset has two copies of the archive logs (which is what I want), and I expected the logs to be deleted after being backed up 2 days (each day is twice, 2 days = 4 times). But it's not deleting the logs, even after 6 runs.
I am trying to restore a backup from a live server to a dev server. Have moved nackup sets. Created a windows service to match the old sid on live system. copied the pfile from live and changed the locations of the folders to suit dev. set oracle_sid to the new sid(as created to match live)
connected to rman startup nomount set dbid to the live number restore controlfile alter database mount catalog'd all the backupsets
[code]....
but it fails when it tries the restore .. see below ..The path it is showing is the old path from the live server, so it appears to eb ignoring my set newname statements even though they succeeded earlier - should be restoring them to d:oracleoradatasun43dev ? Does the whole thing have to be put inside one run block or can I put bits in one run block and other bits outside of it etc?
RMAN> restore database;

We are exploring Oracle Secure Backup in our environment as legato networker alternative. But RMAN backup in OSB is very slow due to sbt wait event (sbtwrite2). it can backup 5GB/hour. We think this not normal behavior. we have checked network throughput between media server and client server. It can send 50 GB data by 30 min.
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)
I am getting error when i try to restore one tablespace using RMAN.
RMAN> restore tablespace test;

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.

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 ...

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;

We are using Oracle 10g R2 in Windows Server 2003. I'm trying to restore a database in a new server, using RMAN backups.
Our external consultant configured RMAN scripts for full and incremental backups but never tested them . Since he just doesn't show up, I'm forced to tested them, restoring the whole database in a new server.
My instance is named MTDPROD, and I will create all from scratch.
At current server, RMAN files are generated in: //192.168.1.149/g$/XXXSRV4-ArcLogs/MTDPROD/RMAN
At new server, I run all these commands:
C:>oradim -new -sid MTDPROD -intpwd mtdprod Instance created -- I created the relevant folder hierarchy under <ORACLE_BASE> directory -- Then, I created the relevant directories for Oracle Database, as follows: --a. Create BDUMP, CDUMP, and UDUMP directories under '<ORACLE_ BASE>
[code]....
By instance, I see a lot of this kind of files:
- FULL_MTDPROD_20110529_386_1.BAK - INCR_MTDPROD_20110621_480_7.BAK And only see these two files: - C-2169285856-20110527-03 - C-2169285856-20110527-04
It seems that this C-2169285856-.... files only were on 27/05/2011 and then no more. However, the FULL_... and INCR_.. files are generated every day. The FULL is generated at the end of each month and INCR is generated every day.
This is the backfull.sql:
run { allocate channel c1 type disk maxpiecesize=4G; CROSSCHECK archivelog all; backup incremental level 0 format '\192.168.1.149g$XXXSRV4-arclogsMTDPRODRMANFULL_

Tape streaming is not happening while performing RMAN tape backup. On investigation, you find that it is not because of the incremental backup or the empty file backup and that RMAN is sending data blocks to the tape drive fast enough.What could be a solution to make tape streaming happen during the backup?
A.Configure backup optimization
B.Configure the channel to increase MAXOPENFILES
C.Configure the channel to increase the capacity with the RATE parameter
D.Configure the channel to adjust the tape buffer size with the BLKSIZE option
We have the requirement of performance testing of our proposed production platform, for this i am asked to take RMAN backup of clean position (Say Day0 or baseline backup) and restore it multiple times for few rounds of testing. My question is after 1st restore (with set until time of day0 position) if i open the database with resetlogs, would i be able to restore same clean backup again? I am using control file in the environment instead of RMAN catalog database. What i can do to make this scenario work? I am already in preperation of setting rman catalog database.
