Suppose I take a multi stream backup, say 3 streams.
So if a control file is backed up in say backup set 1, so is the whole control file is backed up in one backup piece or it may span multiple pieces?
A backup set may have multiple backup pieces.
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 ;

I want to ask if I restore a control file from backup of say day2 and I recover till day1 using RMAN script, then what will be the state of my database? I mean day2 control file may be having SCN-Day2, and I am instructing RMAN to recover till past point in time that is SCN-Day1.

So /dd_oraback is a Data Domain mount. Not sure if that makes any difference or not.
I have an oracle autoback of controlfile and spfile. I am trying to restore the production database using this backup, into a new server with a different directory structure.
I have completed the following steps in the restore process.
1. Creating a pfile from spfile
2. Changing the the location of cdump, udump, bdump and the control files ( there are three )
3. Then creating a spfile from this pfile
I am stuck on the next step where to rename all the datafiles and tempfile and restore the database. Following is what I did.
After mounting the database in RMAN, tried to run the following.

I take hot backup of database at 10:00 am.After taking the hot backup 50 archived logs are created.Out of 50 i have backed up first 25 of them and at 5:00pm i lose complete database including control,data and the last 25 archived log files that were not backed up.So I am using latest hot backup to recover
I restore the control file backup and datafile backup taken during ho tbackup(10 am) and i issue the command
.......startup mount
>>>>>>>Recover database until cancel
!!!!!!! Apply the available 25 archive logs
then i give "cancel" since I dont have the next redo log .Now in which mode will the database open(Reset logs or no reset logs)
I want to restore control file from backup set,just as the flowing command,where location does the control file be restored to? how can i specify the location when restore control file?
restore controlfile from '/u01/rman_backup/mybak/df_768589733_7_1.bak';

At first i have executed the statement
sql> alter database backup control file to trace;
then i have removed the control files and enterd some data in a table and committed it.As my oracle is not shutting down, so i shut aborted it. Now after saving the last file from the udump as obkp.sql i am unable to edit this file and use.
how to edit and use this file, so that i can startup my database normally.
When i issue this command ,how many times to backup controlfile?

1. Why aren't my data files backed up to the location I specified when I backup using PLUS ARCHIVELOG syntax?

3. Is there a way to combine backup of all files (data files, control file, spfile, redo logs & arch redo's) in one backup set, one file?

The 01:40 record will come from our nightly command:

DATABASE INCLUDE CURRENT CONTROLFILE
The 11AM records will come from the command:
BACKUP INCREMENTAL LEVEL=0 FORMAT 'ctl_%t_%s_%p' CURRENT CONTROLFILE;
(I know backups shouldn't still be running at 11am and we don't need level 0 backups every night, that's a seperate issue I'll be addressing! ) I see there's been a similar entry here in v$backup_datafile for all backups that there's records for. The database is up and running just fine. There are no unusual errors being reported by the database in OEM or the alert log.I tried looking at both our control files (yes, should have 3 - something else I've listed to change!) with dbverify which showed no issues - though I'm not sure if this is designed to work with control files.
If so, how could I confirm whether it's an issue with a specific controlfile (I'm assuming it's not an issue with the backup to tape itself, as it's reporting the same corruption every day)?I'd obviously like to diagnose this now while the db is up and running, rather than at 4am some morning during a crash and finding out my backup control files are no good!
We're running 10.2.0.4 Database on AIX with no catalog Database.We keep all the backup info in controlfiles only.When we do that backup, we're able to successfully back it up (including archivelogs). But I'm unable to find any records in the controlfiles.

I've pasted some of the results of an RMAN backup that I ran. It says that it's backing up both the Control File and the SPFILE, but it appears that only one file is being created. Is this correct? How does this work? Are both files combined into the C-3843121877-20120619-00 file?

I want to create binary copy of control file every time I do backup. I am using sql "alter database backup controlfile to ''+FRADG/TESTDB/controlfile/controlfile.ctl'' "; in my rman backup script. If I run it second time I got errors as it does does not allow to overwrite existing one.

I faced one strange behaviour of rman backup after adding new file system for datafiles . I have OMF datafiles . 4 days ago i had only one file system /data01 and my DB_CREATE_FILE_DEST is set to /data01. my rman backup was creating 14 to 15 bacup pieces with parallelism 5 . which is normal with 84 datafiles .Now i added one more file system /data02 . but after adding this file system rman backup is creating so many backup-pieces around (40-45) with same rman configuration . nothing changes at rman script .
View 3 Replies View RelatedI am having a issue, we are trying to restore our db from control files using Symantec Backup exec, but job fails giving me error go to table spaces select all table spaces and unchecked roll forward.
i am unable to find way to uncheck the table spaces. Here is the complete description.
Cause
The system catalog tablespace "syscatspace" contains all of the system catalog information for the tables. Syscatspace needs to be rolled forward first, and then the other tablespaces must be rolled forward.
Solution
Workaround:
When the restore operation is run from a tablespace level backup, perform the rollforward for the syscatspace tablespace first and then for other tablespaces.
Execute the rollforward operation as a DBA operation. The sequence of the recovery process should be as follows:
1. Select all tablespaces, uncheck the rollforward option and run the restore job.
2. Run the rollforward operation as a DBA initiated operation:
rollforward syscatspace to point in time / end of logs. e.g. db2 => rollforward database UEXIT to end of logs and complete Tablespace (SYSCATSPACE) online
3. Perform rollforward of all other tablespaces.
e.g. db2 => rollforward database UEXIT to end of logs and complete tablespace (SYSTOO LSPACE,USERSPACE1) online
Refer to IBM DB2 documentation for more information on DBA-initiated operations.
We are trying to restore a database to a cold backup DBID.However while our datafiles were backuped up for 6 months retention we found out subsequent delete obsolete command wiped out the Control file related to this backup piece..Now what is left with this backup piece is just datafiles..
Can we still recover the database with a subsequent controlfile autobackup for the same DBID.?
Can the control file be used to store scripts which are used to perform backups? I know the RMAN recovery catalog can.
Does the SHOW command display detailed reporting on the RMAN catalog contents other than configuration information?
I've got a legacy SAP system with oracle 8i on Tru64. No changes at all are made but for legal reasons we have to keep it up and running.
we currently do a full backup monthly by shutting down oracle and doing a backup of all the files to tape and that takes around 12 hours.
If I stop doing the full backup and I only backup the control file and the archived redo log files every month and I had to restore the full database years from now, would I be able to restore the database using the last full monthly backup and use the latest control file and archived redo log files?
Is it possible to un-delete the deleted backup pieces, then catalog them to RMAN?

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.
View 3 Replies View RelatedI am designing the scripts for RMAN backup.
Currently we have 14 days retention policy for daily and weekly backup. but we will have 186days retention for monthly backup, that's mean its should be recoverable around that 3 month (for monthly).
My question is, What should I put the scripts for monthly backup ?
I saw some example its for offline backup:
BACKUP DATABASE UNTIL 'SYSDATE+365' NOLOGS;
But I want the backup should be online ?
Currently our weekly backup like this
#!/bin/bash
# SID= env | grep ORACLE_SID | cut -c12-15
export ORACLE_HOME=/oracle/BWD/112_64
export ORACLE_SID=BWD
LOGFILE=/tmp/BWD-weekly-`date +%y%m%d%H%M`.out

And Daily backup:
#!/bin/bash
SID=EPD
export ORACLE_HOME=/oracle/$SID/112_64
export ORACLE_SID=$SID
#LOGFILE=/tmp/EPD-weekly-`date +%y%m%d%H%M`.out
