RMAN Cold Backup FINAL

We are upgrading our production database in 2 weeks. We will be using datapump to export the source and then import to the new target database. As a final backup before the source export I want an RMAN cold backup to get a consistent point-in-time backup. The database is in archivelog mode. After shutting down and using RMAN to perform the cold backup, I will have to open the database to do the export. So how would RMAN restore the production source database back to the time the database was down if additional archive logs are generated during the export? Would I have to specify a time or SCN or would I have SCN gap issues in the recovery of the source database? This is for the source database that will no longer be used once the import to the target and subsequent ERP upgrades are applied. However, I need to preserve the source for a month or so. I could also continue to take hot RMAN backups after the export is completed, but I need the point-in-time recovery to the exact time of the export. I currently only use online RMAN backups since this is a 24/7 database, but I have a short window to upgrade to the new production database.
Thank you,
Curt Swartzlander

TTo do an incomplete recovery with RMAN requires to specify a date/time or SCN or log sequence because by default RMAN will try to do complete recovery: http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta065.htm#RCMRF160

1) Where do i need to place the prod RMAN COLD backup files in test server?
2) If i ran below command how RMAN will know where did i placed the backup in test server?
In Test Server

User managed coldbkp vs rman cold backup

Hi,
I confused about rman cold backup in no catalog mode while restore the backup.please anyone clarify it.
1,I am not confused about user manged cold backup.I took the backup (spfile,control file,redo file,datafile,password file.)Is it right one?
2,In rman cold backup in no catalog mod, we used backup sets for backup,control file is autobackup is enabled.
The backup set format is not OS format.The backup stored at flash recovery area.
Just assume,
I lost all files(spfile,control file,redo file,datafile,password file.)How to recover that.
I am not able to identity spfile & control file in backupset in flash recovery area.
How to identity the spfile,control file during the restoration?
3,Rman takes the copy of online redo file in cold backup?
If it's not,How to recover the database & in user managed backup,copy of online redo log file is must?
4,What is the difference between dbid & sid?when it is used?
5,Can i specifty format for spfile when i take the backup? can i use trace file(control file ) for restoration?
I read the oracle documents, but I am not understand the above things clearly.please anyone rectify it.

Yes,you are right,but first need SHUTDOWN IMMEDIATE;

If you do not explicitly configured rman then yes it will backup to FRA.
Just assume,
I lost all files(spfile,control file,redo file,datafile,password file.)How to recover that.
First need SET (EXPORT) ORACLE_SID and then
rman target /
startup force nomount;
restore spfile from 'autobackuplocation';
startup force nomount;
restore controlfile from 'autobackuplocation';
catalog start with 'backupandarchiveloglocation';
restore database;
recover database;
alter database open resetlogs;
I am not able to identity spfile & control file in backupset in flash recovery area.
From rman you can execute LIST BACKUP or LIST BACKUP OF CONTROLFILE;
How to identity the spfile,control file during the restoration?
3,Rman takes the copy of online redo file in cold backup?No,RMAN do not backup online logs,due to this do not need.
If it's not,How to recover the database & in user managed backup,copy of online redo log file is must?
If cold backup then you can open database with resetlogs option and online logs will create automatically(if you did not copy this logs)
>
4,What is the difference between dbid & sid?when it is used?
DBID is unique identify database in recovery catalog and using this you can restore controlfile easily.But SID is ORACLE_SID and identify instance.This is environment variable like ORACLE_HOME
5,Can i specifty format for spfile when i take the backup? can i use trace file(control file ) for restoration?
Yes you can identify format manually for spfile. ALTER DATABASE BACKUP CONTROLFILE TO TRACE ... this statement use to getting script for recreating controlfile again.So this is not backup and you can notuse for restoring controlfile.If you do not have a backup of controlfile and all datafilesd available then you can use this statement.
I read the oracle documents, but I am not understand the above things clearly.please anyone rectify it.All these and with all situation clearly explained below doc

RMAN Restore using RMAN COLD Backup!!

Hi All,
I Need to restore a database using rman cold backup taken a month back.
Can i use Duplicate database option until time/scn just like we do for hotbackup or is there any other procedure for cloning/refreshing the database using RMAN COLD BACKUP of source.
Thanks & Regards,
Pdev

This may be used to clone db
connect target sys/sys@<dba>
connect catalog rman/rman@<dba>
connect auxiliary sys/sys<new>
run {
set newname for datafile 1 to 'e:\oracle\oradata\giri\system01.dbf';

set newname for datafile 3 to 'e:\oracle\oradata\giri\users01.dbf';
set newname for datafile 4 to 'e:\oracle\oradata\giri\indx01.dbf';
set newname for datafile 5 to 'e:\oracle\oradata\giri\example01.dbf';
allocate auxiliary channel dupdb1 type disk;
set until sequence 2 thread 1;
duplicate target database to dupdb
logfile

RMAN Cold backup script

DB version :10.2.0.4
Do you find anything wrong in the below mentioned RMAN cold backup script? Any enhancements, corrections required?
shutdown immediate;
startup mount;
backup database including current controlfile tag='full_bkp';
startup;
crosscheck backup;
delete noprompt obsolete device type disk;
resync catalog;
}

Since you are doing a SHUTDOWN IMMEDIATE and STARTUP MOUNT before the BACKUP, there will be no ArchiveLogs generated while the backup is running --- as the database is not OPEN.
However, the PLUS ARCHIVELOG can include ArchiveLogs that had been generated from the previous STARTUP or ALTER DATABASE OPEN.
(In that case, I would suggest an SQL 'ALTER SYSTEM ARCHIVE LOG CURRENT' before the SHUTDOWN IMMEDIATE).
Is your database running in ARCHIVELOG mode ? If not, then this discussion is moot.
If yes, the next question is, obviously : Why not take a Hot Backup while the database is running (in which case you MUST backup archivelogs !)

RMAN cold backup taking more time than usual

Hi everybody.. please help me resolving below issue..
I have configured the RMAN in one of the production database with separate catalogue database six months earlier. I have sceduled weekly cold backup through RMAN on sunday 6pm. Normally it used to take one hour to complete the cold backup and database goes down soon as the job starts.
But since from then every week the time taken to just initiate the database shutdown continuosly increasing and recently when i checked it is taking 1 hour to initiate the database shutdown. Once the initiation starts it hardly take 1 to 3 min to shutdown.
Database is up and running during that one Hour. I was in the assumption that RMAN takes some time to execute its internal packages.
Please help
Regards,
Arun Kumar

Hi John and Tychos,
Thank you very much for your valuable inputs.
Yesterday there was cold backup and i have monitored the CPU usage. But there was no load on the CPU at that time and CPU usage was 0%
I have tried connecting to RMAN manually and it connects within a second. And also noticed in prstat -a that rman connects as soon as the job starts.
So i think that its taking time at the deleting obsolete backups.
But I have observerd following observation.
Before executing the delete obsolete command as mentioned before
RMAN> REPORT OBSOLETE RECOVERY WINDOW OF 35 DAYS DEVICE TYPE 'SBT_TAPE';
Report of obsolete backups and copies
Type Key Completion Time Filename/Handle
Backup Set 83409 25-JUL-09

Backup Set 83411 25-JUL-09
Backup Piece 83589 25-JUL-09 arc_SID_20090725_559_1
After executing the delete obsolete command
RMAN> REPORT OBSOLETE RECOVERY WINDOW OF 35 DAYS DEVICE TYPE 'SBT_TAPE';
Report of obsolete backups and copies
Type Key Completion Time Filename/Handle
Backup Set 83409 25-JUL-09

Backup Set 83411 25-JUL-09
Backup Piece 83589 25-JUL-09 arc_SID_20090725_559_1
Please advice me on the following.
1. Why its not deleting the obsolete BACKUP SETS?
2. Is it normal that RMAN takes this much deleting obsolete backup sets? How can i minimize the time taking for deleting obsolete files.
Thanks and Regards,
Arun Kumar

or after cold backup, go to mount ,
create trace file of controlfile becuase you are chaning database name
recreate the controlfile

RMAN cold backup without shuting down R12 application services?

Hi,
Due to some reasons I can't shutdown appstier bcz every time I have to regenrate JAR files.I want to take RMAN cold database backup with stopping all services or I want to shutdown only concurrent manager(adcmctl stop) and apps listener(adalnctl.sh stop).Please comment if this is workable.
Thanks

RAC to RAC CLONE FROM RMAN Cold Backup

Hi All,
I need your kind assistance in Cloning my Oracle RAC 11.2.0.2 Environment to remote host. Following is Disk layout
DGVOT (ASM Disk group holding OCR and Voting Disk)
DGDATA (ASM Disk Group Holding Data FIles)
DGFRA (ASM Disk Group Holding Fast Recovery FIles)
Remote Host is on different location so cannot use RMAN duplicate with auxiliary channel.
Have luxury of downtime so I want to take RMAN Consistent( Cold Backup)
SAME Disk layout is available to remote hosts.
11.2.0.2 CLusterware (GI) Plus the oracle binaries are already installed.
Can any body tell me the steps to
1) How to take cold backup to disk so that I can tar and copy to remote host
2) clone the database on remote host
3) How i will add the database listener and other resources of this databasee to clusterware.
actually this is my first RAC clone so i am not much aware of detail steps.
I have gone though many metalink notes but no one is matching with my requirements. your expert advice will help me a lot
Regards,

Hi
1) How to take cold backup to disk so that I can tar and copy to remote host.
Use Rman for cold backupIn mount stage execute
RMAN>backup database plus archivelog format '<disk_path>/dbp%U';
RMAN> backup current controlfile format '<disk_path>/ctl%U';
Copy thse backup sets to remote host
2) clone the database on remote host
Create Similar ASM Disk groups as on source
create pfile/spifile, startup instance in nomount mode
catalog backup set
RMAN> catalog start with '<backup_set location>';
Restore controlfile
RMAN>restore controlfile;
RMAN> restore database;
RMAN> recover database;
On successfull recovery
RMAN>sql 'alter database open';
3) How i will add the database listener and other resources of this databasee to clusterware.
User srvctl to add resources
Usage: srvctl <command> <object> [<options>]
commands: enable|disable|start|stop|relocate|status|add|remove|modify|getenv|setenv|unsetenv|config|convert|upgrade

Rman cold backup for oracle rac

Hi experts;
I want to create a cold backup for an oracle 10g rac DB.
It has 2 nodes, it's not in archive log, this will be the next step.
But now, I want to backup before to proceed.
My doubts are:
I need to shutdown the both nodes?
If yes:
I need to startup nomount just in one node?
If there any document with this specifics steps?
Thanks for your help.
Al

Cold backups are done with the DB completely shut down.
For RAC the data files are used by all nodes in the cluster.
You need to shut down all instances in the RAC.
Then use your OS utilities or RMAN to do the backup.
Here is an 'Ask Tom' topic that discusses this:

RMAN cold backup vs hot

To apply a patch it taking around 3 hours including backing up database.
My question is why should i take cold backup, why not hot backup that can be taken online by placing tablespace into backup mode. Then we can reduce the downtime of backup.
oracle 10.2.4

If you are talking about Oracle Database patch set/interim patch/CPU patch, you don't need to do a cold backup of the database: if you are doing a hot backup with archived redo logs backups, you can restore database to a point in time just before applying patch (incomplete recovery). Of course, this hot backup must be run before patch installation and not during patch installation.
Note that :
- you must also backup ORACLE_HOME installation directories to be able to restore ORACLE_HOME in this case
- you must also backup Oracle Inventory
- if you using RMAN, you don't need to put tablespace in backup mode when doing a hot backup.

Restore 11g rman cold backup on same server.

Hi All,
I have a requirement , where we have to clone one development database's to other database's sitting on the same host.
I have taken the cold rman backup and copy it different database's local folder.
I changed the db_name in target pfile and did the nomount , but when I tries to restore the controlfile , it throws me below errors.
Just to add to to it, I was ale to restore the controlfile to the location specified in pfile.

Restoring and Recovering from RMAN cold backup

DB Version: 11gR2
os : Solaris
Before dropping a DB we had taken an RMAN backup of the DB using
RMAN> backup database;We hadn't set a FORMAT (like db_%d_S_%s_P_%p_T_%t) for this DB , so the backups went to ORACLE_HOME/dbs directory. The 2 backup files are
/u02/app/oracle/11.2/db/dbs/01mo9fms_1_1
/u02/app/oracle/11.2/db/dbs/02mo9fnc_1_1 -- spfile and control fileNow we need to recreate this DB on a new server.
In the new server, we've placed the backup files in /u04/backup/rmanbkp .
Since We hadn't set a FORMAT parameter for the original DB which we have dropped what format i will give during restore?
Will RMAN automatically recognize the FORMAT of the backup piece and restore ?
RMAN> run
allocate channel c1 device type disk format 'i_dont_know_the_format';
allocate channel c2 device type disk format 'i_dont_know_the_format';
restore controlfile;
restore database;
}This the SHOW ALL output from the DB we have dropped .
RMAN> show all;
RMAN configuration parameters for database with db_unique_name BRCFTST are:

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

Rman cold backup on Standby

10.2.0.4 + RMAN + catalog + Data Guard
Hi, I am confused about couple of things here :) Wondering if anyone has faced the same issues.
1. Documentation states the following about taking backups on standby, rather then on primary:
Only the backups that have been written to tape are available to the primary database for restoration and recovery.So if I took a backup to disk and then it went to tape (not directly to tape via RMAN), I cannot use this backup to restore my primary? This doesn't make sense.
2. Oracle recommends to use incrementally-updateable image copy backups as the best practice of backing up standby database. Does anyone have a link to a good explanation of this? Thank you!

Oracle documentation reads:
The accessibility of a backup is different from its association. In a Data Guard environment, the recovery catalog considers disk backups as accessible only to the database with which it is associated, whereas tape backups created on one database are accessible to all databases. If a backup file is not associated with any database, then the row describing it in the recovery catalog view shows null for the SITE_KEY column. By default, RMAN associates files whose SITE_KEY is null with the target database.

If I take backups to disk on the standby and they don't go to FRA (due to space limitations there) and I then move those disk backups to tape (outside of RMAN), can I use those backups to restore on primary?
Oracle documentation further reads (same site):
When deciding on your backup strategy, Oracle recommends that you take advantage of daily incremental backups. Datafile image copies can be rolled forward with the latest incremental backups, thereby providing up-to-date datafile image copies at all times. RMAN uses the resulting image copy for media recovery just as it would use a full image copy taken at that system change number (SCN), without the overhead of performing a full image copy of the database every day. An additional advantage is that the time-to-recover is reduced because the image copy is updated with the latest block changes and fewer redo logs are required to bring the database back to the current state.
When you take a backup on standby, you still have to take a control backup on BOTH.
