RMAN Alternate host restore, Source database on ASM

I need to restore a tablespace to a remote host. The source Database is on ASM. I'm fairly new to ASM, but I have experience with RMAN. I have a database that's on ASM and I would like to restore one of its tablespaces to a remote host. Any help would be appreciated.
Thanks,
Alex

Hi user12345,
one way would be to use Transportable Tablespace.
This would utilize expdp resp. exp.
There is something new in 10gR2 call transportable tablespace from backup.
Here expdp is intergerated into an RMAN command.
For more see my post:
http://sysdba.wordpress.com/2006/04/11/transportable-tablespaces-from-backup-with-rman-in-oracle-10g-release-2/
Hope it hleps,

Using RMAN restore the database on a new host in ASM

Hello All,
I am trying to restore a database without using RMAN database duplicate. I want to do set new name for datafile and rename log file for online logs and change database name at last using NID.
here are details
source database - APSPROD / server - X
target database - EMERALD / Server -Y
Compressed backup is copied to destination server and I am trying to restore database using RMAN. Here is my init.ora file
cat initAPSPROD1.ora
DB_NAME=APSPROD
compatible=11.2.0.3
sga_target=8G
CONTROL_FILES='+DATA_DM01/EMERALD/controlfile/cntrl01.dbf','+RECO_DM01/EMERALD/controlfile/cntrl02.dbf','+DATA_DM01/EMERALD/controlfile/cntrl03.dbf'
DB_BLOCK_SIZE=8192
db_file_name_convert=(+DATA_DM01/APSPROD,+DATA_DM01/EMERALD)
log_file_name_convert=(+DATA_DM01/APSPROD,+DATA_DM01/EMERALD,+RECO_DM01/APSPROD,+RECO_DM01/EMERALD)
DB_RECOVERY_FILE_DEST='+RECO_DM01'
DB_RECOVERY_FILE_DEST_SIZE=5500G
So from above you can see that control file should be restored to +DATA_DM01/EMERALD and +RECO_DM01/EMERALD path.
Question -
when I am trying to restore control file. It creates an ASM alias name in +DATA_DM01/EMERALD/controlfile/cntrl01.dbf',+RECO_DM01/EMERALD/controlfile/cntrl02.dbf',' and +DATA_DM01/EMERALD/controlfile/cntrl03.dbf' but It creates fully Qualified ASM Filename under +DATA_DM01/APSPROD and +RECO_DM01/
Here is output

How to restore a database from host A to host B by using RMAN

Hi there
I wanted to restore 1 database from machine A to machine B with the differente files systemes. I did these steps below, but I have a problem when I restore the controlfile from machine A to machine B.
1-copy the controlfile from machine A to machine B by using OS utility.
2-startup nomount the database on machine B.
3-connect target and catalog RMAN.
4-I have to restore the controlfile from last full backup of the machine A to machine B (see the procedure RMAN).
I have the error messages like:

Hi there
I'm also trying to restore a full RMAN backup to our DR site using Netbackup as MML
My scenario is:
We have one tape library at our PROD data center and another one at our DR site both using Netbackup as Storage manager
I performed a full RMAN backup on 4 DLT tapes with recovery catalog at our PROD datacenter, then I removed the 4 tapes and place it in our tape lib at DR site
I tried to import the tapes using bpimport from Netbackup which has been successful up to now
But when I tried to restore controlfile from RMAN, I get the following error:

Restore single datafile from source database to target database.

Here's my issue:
Database Release : 11.2.0.3 across both the source and targets. (ARCHIVELOG mode)
O/S: RHEL 5 (Tikanga)
Database Storage: Using ASM on a stand-alone server (NOT RAC)
Using Oracle GG to replicate changes on the Source to the Targets.
My scenario:
We utilize sequences to keep the primary key in tact and these are replicated utilizing GG. All of my schema tables are located in one tablespace and datafile and all of my indexes are in seperate tablespace (nothing is being partitioned).
In the event of media failure on the Target or my target schema being completely out of whack, is there a method where I can copy the datafile/tablespace from my source (which is intact) to my target?
I know there are possibilites of
1) restore/recover the tablespace to a SCN or timestamp in the past and then I could use GoldenGate to run the transactions in (but this could take time depending on how far back I need to recover the tablespace and how many transactions have processed with GG) (This is not fool-proof).
2) Could use DataPump to move the data from the Source schema to the Target schema (but the sequences are usually out of order if they haven't fired on the source, get that 'sequence is defined for this session message'). I've tried this scenario.
3) I could alter the sequences to get them to proper number using the start and increment by feature (again this could take time depending on how many sequences are out of order).
I would think you could
1) back up the datafile/tablespace on the source,
2)then copy the datafile to the target.
3) startup mount;
4) Newname the new file copied from the source (this is ASM)
5) Restore the datafile/tablespace
6) Recover the datafile/tablespace
7) alter database open;
Question 1: Do I need to also copy the backup piece from the source when I execute the backup tablespace on the source as indicated in my step 1?
Question 2: Do I need to include "plus archivelog" when I execute the backup tablespace on the source as indicated in my step 1?
Question 3: Do I need to execute an 'alter system switch logfile' on the Target when the recover in step 6 is completed?
My scenario sounds like a Cold Backup but running with Archivelog mode, so the source could be online while the database is running.
Just looking for alternate methods of recovery.
Thanks,
Jason

Let me take another stab at sticking a fork into this myth about separating tables and indexes.
Let's assume you have a production Oracle database environment with multiple users making multiple requests and the exact same time. This assumption mirrors reality everywhere except in a classroom where a student is running a simple demo.
Let's further assume that the system looks anything like a real Oracle database system where the operating system has caching, the SAN has caching, and the blocks you are trying to read are split between memory and disk.
Now you want to do some simple piece of work and assume there is an index on the ename column...
SELECT * FROM emp WHERE ename = 'KING';The myth is that Oracle is going to, in parallel, read the index and read the table segments better, faster, whatever, if they are in separate physical files mapped by separate logical tablespaces somehow to separate physical spindles.
Apply some synapses to this myth and it falls apart.
You issue your SQL statement and Oracle does what? It looks for those index blocks where? In memory. If it finds them it never goes to disk. If it does not it goes to disk.
While all this is happening the hundreds or thousands of other users on the database are also making requests. Oracle is not going to stop doing work while it tries to find your index blocks.
Now it finds the index block and decides to use the ROWID value to read the block containing the row with KING's data. Did it freeze the system? Did it lock out everyone else while it did this? Of course not. It puts your read request into the queue and, again, first checks memory to see if it needs to go to disk.
Where in here is there anything that indicates an advantage to having separate physical files?
And even if there was some theoretical reason why separate files might be better ... are they separate in the SAN's cache? No. Are they definitely located on separate stripes or separate physical disks? Of course not.
Oracle uses logical mappings (tables and tablespaces) and SANS use logical mappings so you, the DBA or developer, have no clue as to where anything physically is located.
PS: Ouija Boards don't work either.

Restore 9i database from tape to 10g ASM

We have a plan to upgrade 9i database to 10g ASM. The current 9i database is using file systems on AIX5L. This is a VLDB of size >3TB. I want to restore production copy to test environment. There is no test environment for this database now. So, if I want to restore to test, we need 3TB for file systems and another 3TB for ASM disk groups for migration. Instead, Is there any way I can restore production Oracle 9i backup directly into Oracle 10g ASM disk groups. So that, we can save 3TB of space allocation for file systems. Also, it will save time instead restore 9i database to test, upgrade to 10g and then migrate to ASM.
I agree that this is the space to be allocated temporarily. But, as per our company standards, the project needs to procure temporary space too.

You cannot restore a 9i RMAN backup into 10G.
You can use either export/import or transportable tablespace.
You can use below method:
1. Use transportable tablespace to migrate 9i to 10G.
2. Initially migrate all datafiles to filesystem.
3. Then migrate all datafiles to ASM.
Apart from this , you have one more option . upgrade existing 9i database to 10G and the use RMAN to restore it to 10G ASM database.

Restoring Database to ASM from tape

We're restoring a database from tape using Oracle 10.2.0.5. We explcitely specify the location for every single file with SET NEWNAME FOR DATAFILE X. The files that get restored don't match the NEWNAME format we set it to even though the log says it restored the file to that name. I don't know what's occuring under the hood of ASM, but it appears OMF is coming into play and generating names for the files. it's becoming a problem because when we restart the restore (which occurs often due to size of the database, length of time it takes, and drives going down) we start all over because RMAN doesn't know of the existing files. This doesn't seem to be normal behavior, and I know it's not like this during file based restores.
Does anyone know what's going on within ASM itself? It appears to be normal behavior when restoring to ASM and the names are later set appropriately after the SWITCH DATAFILE ALL. That's what I think would happen. It's currently a problem restarting restores.
Any insight or help is appreciated. Thank you

then if you restore database from tape/disk, it will place all the datafiles as '+data/db_unique_name/datafiles';

RMAN can backup/restore diferent versions of Oracle DataBases regardless OS

Hi,
I am evaluating Recovery Manager to backup and restore Oracle databases.
I have to backup/restore diferents versions of Oracle database, these databases are running in diferents operating systems (AIX, LINUX, Windows)
For example:
Oracle DataBase 9 in AIX 5.3 system
Oracle DataBase 10 in Lunix system
Oracle DataBase 9 in Windows system
I want to have a single RMAN server in order to backup/restore all my Oracle DataBases, is it possible?
A single RMAN server can backup/restore diferent versions of Oracle DataBases regardless the operating system?
If the answer is yes, do I need to have an specif operting system in my RMAN server? (AIX, Linux, Windows, etc.)
Thanks for your help;

Hi,
Your question:
I want to have a single RMAN server in order to backup/restore all my Oracle DataBases, is it possible?
Sounds more like a machine.
If you would have asked:
I want to have a single RMAN recovery catalog in order to backup/restore all my Oracle DataBases, is it possible?
I would have confirmed as like the other two.
Be aware the catalog version needs to be equal or higher as the highest database version.

Error During restoring a database through RMAN in Oracle 9i

Hi all,
I have taken a full backup in oracle 9i through RMAN in one server(Solaris).
After that moved that backupset to another server. Server Locations are same. I need to restore the backup in the new server.
I am using pfile.
Steps I followed:
1. Using pfile i have started the db in nomount.
2. Then restored the controlfile from backup and mounted the database.
3. then tried to restore the database - I have to restore three of my datafiles to different location, hence i used "set new name "
But RMAN threw an error while restoring.
RMAN-00558:
RMAN-01009:
File not found.
Can anyone help to resolve this error.
Thanks in Advance.

Hi,
Thanks, but I took the backup of the database using the command:
backup database;Only this command i issued.
In the new server, I tried to list the backup using list backup command by putting the db in mount stage.
I m not able to view the backup information.
Is there any command to register the backup information using the catalog?

Migrate entire database to ASM on another server via RMAN minimal downtime

Hi
I was looking for a procedure to migrate non ASM production databases to ASM via RMAN on a separate server with minimal downtime (backup as copy/switch database to copy technique). We have TDPO for tape backup and I normally rman clone test databases between servers but this involves too much downtime for production. The procedure in the ASM Admin Guide (Chapter 8) assumes the databases are on the same server.
Thanks

Tom CullenDear Tom. Why you think you'll have downtime in the production database? The database will be running while the clone will be processing. Check the following link:

You need to use "set newname" before you restore your database.
You can refer this http://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmdupad.htm
RMAN> connect target /

5> alter database mount;
6> restore database;
7> recover database;
8> alter database open resetlogs;
9> }Also, you have connected to the database TEST, so is the TEST database the new database that you want to create using restore method ?
If yes, then how the status of the database is OPEN ? The database status should be nomount before you restore the controlfile.
If the database is not started, then:
RMAN shows as "connected to target database: TEST (not started)
If the database is in nomount stage, then
RMAN shows as "connected to target database: TEST (not mounted)
If the database is in mount stage, then
RMAN shows as "connected to target database: TEST (DBID=xxxxxxxx, not open)
If the database is open mode, then
RMAN shows as "connected to target database: TEST (DBID=xxxxxx)
In the output you mentioned, RMAN is showing the status of the database as opened. So if TEST is the database you are creating, then it has to be in nomount stage. In your case, it looks like TEST is the primary database from which you have taken the backup.

Migrate VLDB(30TB) NonRAC database to ASM

My customer is running 10.2.0.5 database which is 30TB in size. Its HACMP/PowerHA with active/passive configuration.
Customer would like to migrate this database to ASM. They dont take rman backups because of the size of the database and rely on bcv backup technology. Customer would like to know what is the best possible way of doing this migration with minimal downtime and risk.

BCV uses copy on write technology and advanced mirroring techniques. A BCVs can be used to resync data or it can be detached from the active data storage and mounted separately for offline processing.
If a complete restore of an object or previous device clone is sufficient then it can be a quick disaster recovery. However, certain implementations, like EMC Timefinder/Snapshot are not suitable for disaster recovery since they rely on the existence of the original data source.
Anyway, I think BCV technology provides only a very limited way for Oracle database backup since it duplicates data errors and is not suitable for advanced rman database or tablespace restore and recovery. A 30 TB database can be time consuming for RMAN, which also depends on what kind of database it is and, for instance, how frequent a full backup is required, but it can be done.
Regarding NAS, it is just an example to show that affordable storage solutions exist and that it does not have to be expensive EMC storage. I do not see why such a solution cannot meet very strict data center controls in terms of technical aspects.

RMAN Hot backup Restore in new Server

Hi,
Our Current Environment:
Source: Current Production
Database: 11.1.0.7
OS: Windows server 2003 R2
Target Environemnt:
Database 11.2.0.1
OS:windows server 2008 R2
Here my scenario is need to take RMAN Hot backup in Prod Instance and need to restore in New Server with smae SID which is going to use as Prod instance.
Please suggest the detailed steps in order to achive the goal.
Waiting for your thoughts.
Thanks
Shaik

RMAN can make it easy to restore a database to a new host.
Notice that: Using RMAN RESTORE and RECOVER commands to move a database permanently to another host, will keep the original database identifier (DBID) and will therefore cause a conflict in the RMAN repository, because the restored database with the same DBID will be considered the current target database.
Below you may find the steps:
Preparing the New Host
Record the DBID of the source database.
Copy the initialization parameter file from the source database to the new host.
Make sure that all source database backups are available to the new host. Do not connect to the recovery catalog.
Restoring and Recovering on the New Host
Configure environment variables on the new host.
Connect to the new target database with NOCATALOG.
Set the DBID.
Start the instance with NOMOUNT.
Restore the SPFILE from backup.
Shut down the new instance.
Edit the PFILE.
Start the instance with NOMOUNT (again).
Create an RMAN RUN block to restore the control file.
Create an RMAN RUN block to restore and recover the database.
Open the database with RESETLOGS.

RMAN backup and restore for Disaster Recovery

Hi Guys,
I am very new to Oracle and have a question about RMAN backup and restore feature. I am simulating a disaster recovery scenario by having two VMs running oracle 11g, say hosta and hostb, hosta is sort of production db and the other a disaster recovery db (one that will be made primary when disaster occurs). My goal is to backup production db using RMAN and restore it on the other machine. For some reason when I restore the db on hostb, the command restores the previous backup but not the most recent one e.g. I took a backup yesterday (09/20) and applied it to the hostb that worked fine, but when I try to apply a fresh backup from today (09/21) it always picks up the old backup. Here's a dump of the screen:

Any help will be greatly appreciated.
Thanks,

Thanks guys, I really appreciate all your help here. I redid everything all over again to get all the information you guys wanted. Since I noticed that more eyes are looking into this I am going to reiterate my steps one more time followed by specific answers to questions. My first backup on Host B is located under ..../restore_db/backupset whereas the subsequent one is under .../restore_db/backupset/backupset2.
I take backup on Host A using:
rman target /
backup as compressed backupset database plus archivelog;
backup spfile;
quit;
I restore the backup on Host B using:
set dbid=13732232063;
startup force nomount;
restore spfile to '/oracle/app/dev/product/11.2.0/dbhome_1/dbs/spfileforums.ora' from '/export/home/dev/restore_db/backupset/o1_mf_nnsnf_TAG20110928T171830_787gbpxh_.bkp'
shutdown immediate;
startup force nomount;
restore controlfile from '/export/home/dev/restore_db/backupset/o1_mf_ncsnf_TAG20110928T171638_787gbkxn_.bkp'
quit;
/* restart rman here */
alter database mount;
catalog start with '/export/home/dev/restore_db/backupset' noprompt;
restore database;
recover database;
alter database open resetlogs;
quit;
I take another backup on Host A using (notice no spfile backup this time):
backup as compressed backupset database plus archivelog;
quit;
I restore the database on Host B using:
alter database mount;
catalog start with '/export/home/dev/restore_db/backupset/backupset2' noprompt;
recover database;
alter database open;
quit;
Output of List Backup of database (I have done this after I recovered the second time, also note that it is referring to backupset2 which is were my second backup is stored)

Restore Rac database in another cluster

Hello, I have a rac database in a clusterware compose by two node, for example node_1 and node_2, but now I need to pass the rac database from this original cluster to another that already exist.
I have two idea but I do not know if they are correct. One is create a template from my Rac database, and then in the second cluster create a rac database from it. The second idea is to make a copy of the pfile and level 0 RMAN backup in one node of the second cluster and then restore the database there.
Maybe twice idea are bad or maybe exist a better form to do it. I hope you can help me.

Hi,
Well, I believe that I was not clear in my last explanation.
The hypothetical scenario is:
One database using ASM (database name orcl) , two inatances in two separated servers (nodes serv1 and serv2) and two instances ( orcl1 and orcl1).
In this scenary I lost everything and just have the backups of spfile, controlfile, database and archives.
So the steps to recovery is (using serv1):
1- Create the cluster (install clusteware, create CRS/Vdisk, create ASM instance)
2 - Just install the oracle files in all nodes serv1 and serv2, but don't create the instance orcl1 and orcl2.
3 - restore/recover spfile - rman
4 - restore/recover controlfile - rman
5 - restore/recover database with until clause - rman
After these steps the instance orcl1 will be restored by RMAN in the serv1 and the database orcl was created in the ASM.
But, plese correct if I'm wrong, the instance and database will not be registered in CRS (RMAN not register the instance).
So I need to registry the instance and database with srvctl, doing:
1 - create PFILE in serv1 for orcl1 (that point to SPFILE in ASM) and ORAPWD file.
2 - add the database orcl to CRS
3 - add the instance orcl1 to CRS
4 - add the dependency about ASM and orcl1 from the node serv1 (using srvclt)
But after this I have the instance orcl2 in serv2 to create.
Just the instance, because the binaries already installed and the database was already created.
TO complete I need to do the steps:
1 - Copy/Create PFILE for instance orcl2 in serv2
2 - add the instance orcl2 to CRS (using srvctl add instance)
3 - add the dependency about ASM instance (that exists in server2) and Instance orcl2 from the node serv2 (using srvctl)
4 - create PFILE and ORAPWD file.
The question is, RMAN will registry the instanci and database in CRS?
Another question, the RMAN will create PFILE and registry all instances of the original cluster?
I believe that not for two questions, correct?
Exists another path to restore/recover the RAC in this scenary?
Thanks.
