Undo tablespace recovery from RMAN backup

Hi,
Lets's assume we have RMAN backup and archivelog backups, and now
my undo tablespace's disk crashed ,how can i recover?
Can i recover while database is up?
Thanks,
Kumar.

to recover UNDO tablespace from RMAN backup you must shutdown the database and start it in the MOUNT state to recover the missing files as follows
rman target /
RUN
STARTUP MOUNT;
ALLOCATE CHANNEL ch3 TYPE Disk;
RESTORE datafile 'c:\u01\prod3\undo01.dbf';
RECOVER datafile 'c:\u01\prod3\undo01.dbf';
ALTER DATABASE OPEN;
RELEASE CHANNEL ch3;
hope this will help you

Problem in recovery from RMAN backup in case of disk failure

Hi
I have Oracle 9.2.0.1.0 on Windows. Full Hot RMAN backup of database is scheduled on daily basis. I am taking backup on disks. And then i do manually copy them on tapes. If any disk failure occurs than can i recover database completely in this scenario. If tried restoing that backup on different machine as given below
set ORACLE_SID=<name>
rman target sys/<pwd>@ORACLE_SID nocatalog
startup nomount
restore spfile
create pfile from spfile
startup nomount pfile
alter database mount
restore database
Everything worked fine till above steps. Now i will execute last step.
recover database
Here it gives error:-RMAN-06054: media recovery requesting unknown log: thread 1 scn 264750
Still i typed
alter database open resetlogs
Now i can open my database, But is it recovered completely? Or there is loss of some data? Why it is giving this error?
Thanks in advance. Waiting for reply.

I can understand the confusion with this whole concept.
What I meant by all archivelogs is all the archivelogs that were backed up with the backup itself. Again, it is essential to ensure that you archive the current redo log AFTER the backup is performed and then back those archivelogs too. Good thing is, RMAN will take care of this for you if you backup the archivelogs with the BACKUP DATABASE command and/or backup the archivelogs AFTER you run the BACKUP DATABASE command.
Once you've mounted the controlfile and CATALOG the archivelogs, you can go into SQL*Plus and issue the following query:
select SEQUENCE#, FIRST_CHANGE#, NEXT_CHANGE# from v$archived_log
order by FIRST_TIME;This will tell you what archivelog is the latest. Logs generated during the backup may also provide the necessary information. Performing Disaster Recovery should help to understand the full process.
The ONLINELOG directory in FRA is only populated if you've configured your redo logs to be stored there. However, you are on 9i...right? If so 9i doesn't utilize a FRA.

Recovery from RMAN backup.

Hi ,
i have rman level 0 backup on sunday, and level 1 backup monday to friday.
if i want to recover from these backups until friday , which archivelogs will be required?
To be more specific i require archivelogs of only friday or all archivelogs from sunday through friday?
Thanks

How to estimate recovery time from rman backup

how to estimate recovery time from rman backup?
The database is of size 800GB.
the approximate time to backup is 8- 10 hours.

"Recovery time" is : RESTORE DATABASE time + RECOVER DATABASE time.
RESTORE can be done
a. in parallel with multiple channels if your backup was created as multiple backupsets
b. using incremental backups
c. whether the backups are on
i. disk
ii. tape
Alternatively, if you have a Recovery Area with an Incrementally Update backup of the database, you can SWITCH DATABASE almost immediately
RECOVER depends on
a. how many archivelogs (in terms of size, not necessarily number) need to be applied
-- this depends on
i. transaction volume
ii. the "freshness" of the backups (how recent the backups are)
b. whether required archivelogs are available on disk (which can be the case if the database backup itself is a very recent backup and archivelogs since then haven't been deleted {whether they have been backed up or not}) OR whether they need to be restored from
i. disk backup
ii. tape backup

Completeness of Prerequisites for Recovering Tables for PDBs from RMAN Backups

Could you verify the completeness of following prerequisities on pag. 441 of the "Backup and Recovery User's Guide 12c Release 1 (12.1) E17630-14"
Prerequisites for Recovering Tables and Table Partitions from RMAN Backups
■ The target database must be in read-write mode.
■ The target database must be in ARCHIVELOG mode.
■ You must have RMAN backups of the tables or table partitions as they existed at the point in time to which you want recover these objects.
■ To recover single table partitions, the COMPATIBLE initialization parameter for target database must be set to 11.1.0 or higher.
According to my test Database administrator workshop: How to recover a table in a pluggable database from a backup
those prerequisities are valid for CDBs or non-CBDs, but if you want to recover tables or table partitions in PDBs a different prerequisite is needed.
Indeed if you have a backup of only the pluggable database including the missing table (the third prerequisite above), but you don't have any backup of the container database the command...
recover table ... of pluggable database ... until scn ... auxiliary destination ...
will fail with the following errors:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of recover command at 02/12/2014 12:22:18
RMAN-03015: error occurred in stored script Memory Script
RMAN-06026: some targets not found - aborting restore
RMAN-06023: no backup or copy of datafile 3 found to restore
RMAN-06023: no backup or copy of datafile 4 found to restore
RMAN-06023: no backup or copy of datafile 1 found to restore
So to recover table in PDBs you must have also the RMAN backups of the CDB or in the opposite way it's not sufficient to have only the backups of the pluggable database, because during the creation of the auxiliary database the SYS, SYSAUX and the UNDO tablespace are required.

Hi,
Before dropping a DB we had taken an RMAN backup.I hope you were in mount mode.
Will RMAN automatically recognize the FORMAT of the backup piece and restore ?No it won't.
First you have to restore a controlfile in nomount mode with:
restore controlfile from '/u04/backup/rmanbkp /02mo9fnc_1_1';
and do alter database mount.
Than you have to run "catalog start with '/u04/backup/rmanbkp'; " so the instance now knows where to find the pieces.
Now you can run a restore database command.
Than open the database with resetlogs.
Regards,
Tycho

I am not able to restore spfile from rman backup ;;;

Hi,
I would like to know few things
1. How are you setting the db_name ? you can set db_id at RMAN, how are you setting the db_name ?
2. Do you have any default init file at default location ? if yes, is the db_name parameter set correctly in that file ?
Since spfile is yet to be restored, you must set the db_name parameter correctly before you start spfile restore.This can be done with init file at default location which can even contain just one paremeter i.e db_name.

how can i prevent rman setting db_name=orcl which is already exists in the db.. i need to create db from rman backups with different dbname...
whould someone help me out, how can i create database from another database rman backups with different dbname/sid on same host..
My pfile has new db_name , but while db creation rman setting to db_name to source dbname.. it should be new db name that i want create with new db name...
is there any RMAN command to specify new DB name it should set while running
sql statement: alter system set db_name = newdbname -- as part rman script execution...
it appears to be i should not touch the soruce db.. i have access to only source db rman backups and need to create another db with different dbname/sid.. please do help...

When you performing RMAN duplicate why you making your script so complicated?
Your instance name and DB name can be different, But what is the contents in your pfile "D:\TESTDELETE\initclonedb1.ora" ? please do post
Have you started any other services related to ORACLE? check in start --> run --> services.msc any other active oracles services, Make sure you have clonedb1.
Startup in nomount
check the connectivity to target server.
SET NEWNAME FOR TEMPFILE 1 TO 'F:\app\HOME\oradata\clonedb1\TEMP01.DBF';Why you mentioning SET NEWNAME FOR DATAFILE ? You have option of db_file_name_convert/log_file_name_convert in case if your file system different in Target & auxiliary.
BACKUP LOCATION 'F:\app\HOME\flash_recovery_area\orcl\'When you have backup in same location why you are mentioning this clause?
First run duplicate from auxiliary server as
rman target sys/*****@prod auxiliary /
RMAN> duplicate target database to "db_name";
Am not sure what you are trying to do. is it 11gR1 or 11gR2?
You have option of duplicate from active database without having backup also..
here some links please check it.

Windows Server 2012 - Backup failing with Exchange - The application will not be available for recovery from this backup. the consistency check failed

Hi
We have a Windows 2012 server with Exchange 2013, all is working fine except now i am getting issues with the backup.
'Exchange - The application will not be available for recovery from this backup. the consistency check failed for the component Microsoft Exchange Server'
I have checked the database all is fine, i have created a new db and move all mailbox;s over and then removed the old db, i have enabled circular logging and then disabled it, it seems no matter what i do i cannot get a full backup!
i did have to restore the server once and the backups still worked for about 4 days after that and then stopped, i have also tried to remove and re add the backup role!
i am stumped, any advice would be great!

Hi
Ok, i created a test db and tried to back it up right away, it failed, i did not add any mailbox's to it either. i got quite a few events in the windows logs, as well as the same event above i got the following:

Recovery from Online backup

Hai All,
I regularly take hot backup via a script. In script copy all datafiles and archivelogs to the backup destination. One conrolfile is created using 'alter database backup control file to c:/backup.ctl' . Thus controlfile is also generated.
I copy the backup files (includes datafiles and controlfiles) to a test machine . In test machine I created a database with the same name of production database. I replace the present files with the hot backup files (keep existing redo log files). When I open the database, recovery asked... I apply the backup archive log files. Even when reach the maximum archive files in my hand. recvery not stop... . This is the problem .. How It happened ? How to open the database with the backup files in my hand only.
I copy the remaining archive log files and redo log files from production database and apply. then I open the database with resetlogs . It works fine......
How to resolve the mentioning problem in second paragraph?
Please help?

How do you backup your database? Do you using RMAN to backup your database? or you use ALTER TABLESPACE BEGING BCKUP method to backup your database?
Which version of Oracle are you using? Is there anything wrong configure autobackup of controlfile to avoid explicitly taking controlefile bakup?
If you want to test your bakcup or wanted to create another copy (clone) of the database using your valid backup, why did you create the second database and did the other fuss?
You can simply, bring up the instance, restore and recovery using your backups.
I guess, the problem was with redo log files. You have overwritten all the datafiles, controlfile, but not redo log files, may be the redo log sequence mismatch cuased this behaviour.

Recovery from hot backup

I have a problem with recovery hot backup from production database to test database and open it to use.
I have 'hot backup' without temporary tablespace and roll tablespace, I cant shut down production database (24x7), please give me a regulations how to recover database from hot backup, without online redo logs, temp tablespace, roll tablespace only with archive logs, and.....after this ..rename database sid.
Every time when I recovered database, it's still want to recover...and recover from archive logs and I cant open it, it's still inconsistent.Please send me an answer for [email protected]
thanks!

Hi,
What is the OS and version of Oracle?
Do you have all the archivelogs after the hot backup? Is the backup a valid backup? Is it a RMAN backup or normal file system backup of the datafiles?
Regards,
Badri.

Standby database from RMAN backup

I have been assigned to create a standby database from our RMAN backups in a different machine, as this is my first attempt at recovering, I am struggling a bit. I would appreciate if someone can throw any light on what dumb mistakeI am doing here. I ahve absolutely no control over the back up script which is done by my vendor, but can do anything in the reocvery portion. I did try going through the documentaiton and other help available for the last 2 days.
Database : Oracle 10G R2
OS : Windows Server 2003
My backup script is
configure channel device type disk format 'J:\RMAN\RMAN_df_%U' maxpiecesize 2048M;
SQL "ALTER SYSTEM SWITCH LOGFILE";
SQL "ALTER SYSTEM SWITCH LOGFILE";
backup database;
SQL "ALTER SYSTEM SWITCH LOGFILE";
SQL "ALTER SYSTEM SWITCH LOGFILE";
backup current controlfile for standby FORMAT='J:\RMAN\RMAN_sc_%U';
For recovery of a standby database,
I have copied the the back up pieces and the archive logs to the standby server where I have just created an instance with the same name as production db.

Here's the standard dcoumentation on the procedure :
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/rcmbackp.htm#i636377
Appendix "F Creating a Standby Database with Recovery Manager" of the "Oracle® Data Guard Concepts and Administration" guide.
I don't see ArchiveLog backups being done by the vendor's script. How do you backup the ArchiveLogs ?
In your post you state that you have copied the ArchiveLogs. Are they copied to the same log_archive_dest location ? RMAN needs to be "aware" of them. You can use the "CATALOG" command in RMAN to register them into the controlfile.
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta011.htm#sthref230
A Standby Database uses a Standby Controlfile which is created from the Primary (with the "ALTER DATABASE CREATE STANDBY CONTROLFILE AS 'locaion';" command) and then copied over to the Standby server.

How to do media recovery from cold backup?????????/

Hi
i take cold backup of my 9i database ....
in case my database is up .....
how will i recover my database if i lose a single database file and i want to recover it from cold backup......
Thanks in advance
Gagan

Here you go
These are the steps:
1. Restore the lost file from a backup.
2. If the database is down, mount it.
SVRMGR> STARTUP MOUNT PFILE=<location_of_pfile>;
3. Issue the following query:
SVRMGR> SELECT V1.GROUP#, MEMBER, SEQUENCE#,
FIRST_CHANGE#
FROM V$LOG V1, V$LOGFILE V2
WHERE V1.GROUP# = V2.GROUP# ;
This will list all your online redolog files and their respective
sequence and first change numbers.
4. If the database is in NOARCHIVELOG mode, issue the query:
SVRMGR> SELECT FILE#, CHANGE# FROM V$RECOVER_FILE;
If the CHANGE# is GREATER than the minimum FIRST_CHANGE# of your logs,
the datafile can be recovered. Just keep in mind that all the logs to
applied will be online logs, and move on to step 5.
If the CHANGE# is LESS than the minimum FIRST_CHANGE# of your logs, the
file cannot be recovered. Your options at this point would be to restore
the most recent full backup (and thus lose all changes to the database
since) or recreate the tablespace as explained in scenario a.
5. Recover the datafile:
SVRMGR> RECOVER DATAFILE '<full_path_file_name>'
6. Confirm each of the logs that you are prompted for until you receive the
message "Media recovery complete". If you are prompted for a non-existing
archived log, Oracle probably needs one or more of the online logs to
proceed with the recovery. Compare the sequence number referenced in the
ORA-280 message with the sequence numbers of your online logs. Then enter
the full path name of one of the members of the redo group whose sequence
number matches the one you are being asked for. Keep entering online logs
as requested until you receive the message "Media recovery complete"
7. If the database is at mount point, open it.

Unable to restore and recover my Database from RMAN Backup

Dear All,
Iam practicing RMAN in Windows environment.
My configurations are
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION ON; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON; # default
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'F:\Backup\%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'E:\ORACLE\DATABASE\SNCFORCL.ORA';
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'F:\Backup\%U.bak';
Then i took the RMAN backup, now iam shutdown my DB and removed one logfile..
then i tried to startup the DB but it is saying
ORA-00313: open failed for members of log group 3 of thread 1
ORA-00312: online log 3 thread 1: 'E:\ORADATA\ORCL\REDO03.LOG'
So i tried to restore the Database with my rman backup
RMAN> restore database;
But i am unable to restore my logfile in the Datafiles location where as all other datafiles are restored but redo logfiles are not restored.
So, i am unable to recover my DB
Please tell me whether i am doing any mistake, what is the solution for my problem.
Thanks in advance
Mahi

All you restored was your datafiles.
Now issue recover database and that will apply the archive logs.
This is in the oracle documentation.
"You must restore backups of these archived logs for recovery to proceed. You can restore either to the default or nondefault location. If you do not have backups, then you must performing incomplete recovery up to an SCN before the first missing redo log and open RESETLOGS."
http://download.oracle.com/docs/cd/B28359_01/backup.111/b28270/osrecvry.htm
In this case after issuing restore database in RMAN, then issue this.
"Recover database"
It will then be an incomplete recovery. They should have been multiplexed. Did you restore your controlfile with this backup? You may have to issue an "Alter database open resetlogs;"
