How to restore a single instance database to RAC (10g) using RMAN ?

Hi all,
I have a single instance database configured using file system in a unique server, so now I need to restore this database using RMAN to a new RAC environment with two nodes and ASM also.
Does anyone can help with this documentation or a link about any information about this restore using rman ?
I tryied found on metalink but threres isn´t this specific case. Only how to convert single instance to 10g RAC, but without how to use with rman information.
System: Windows 2003
Oracle 10g R2
Thanks.

In essense you are really doing nothing more than restoring a backup on a new host. If you want a blow by blow detail of how to accomplish it take at http://www.oracledistilled.com/oracle-database/restore-database-to-another-host-using-rman
In order to write the files to the ASM Disk groups you will use the SET NEWNAME FOR DATAFILE in your restore script. You will also need to create the ORACLE_BASE/admin/<DBSID> structure on all of node. Once you get the database completely restore you will need to edit the SPFILE to include the proper value for the CLUSTER* parameters and each the node specific parameters. Sorry that it is kind of higher level than what you are probably looking for but the link above and what I put here should get you were want to go.

10gR2 single instance to 11gR2 rac upgrade

Can someone tell me some good approach for upgrading a single instance 10.2.0.2 database of approx size 2TB to 11.2.0.3 rac 2 node db on linux.

Hi;
1. You can upgrade your db to 11gr2 first than convert it to rac
2. You can use RMAN and restore it to new 11gR2 server
3. You can use expdp/impdp to new 11gR2 server

MAIN STEPS IN MOVING 9i single instance TO 10 g RAC

Hello Guys,
colud you give me some basic steps, general idea how to move normal single instance database 9i (windows platform) to 10g RAC (linux)?
Maybe these are correct steps ?:
1 Migrate database to 10g ?
2. Migrate to ASM
3. Duplicate this db twith RMAN to 10g RAC databasE?
Best Regards
Radek

Since you are moving from one OS to another - is export/import an option for the move from Windows to Linux? If yes then here are high level steps:
Export/Import Option:
1) Install and configure CRS/RAC on Linux
2) Create a RAC database on Linux
3) Pre-create tablespaces as it exists in your Oracle9i database
4) Export from 9i and import into 10g.
If not:
On Windows:
1) Install Oracle10g
2) Upgrade your Oracle9i to Oracle10g
3) Install/Configure CRS/RAC on your Linux
4) Create a RAC database.
5) Use RMAN's CONVERT option for cross-platform move of tablespaces from win to linux (check this http://download.oracle.com/docs/cd/B19306_01/backup.102/b14191/dbxptrn001.htm#sthref1383 for more information on this)
You almost got all the steps for the second option, except that I have just included step 5.

Converting single instance database(11gr2) supporting EBS 12.1.3 to 2 node RAC on RHEL.

Hi We are in the process of converting single instance database(11gr2) supporting EBS 12.1.3 to 2 node RAC on RHEL. Which version of RHEL is better? if its 6.x then x?? The oracle document only says RHEL update 6.
thanks in advance.

Hi,
Yes you can use any version but i recommend you to use 6.2
Also refer my post for RAC migration in EBS

Creating a RAC standby database for a single instance database

Dear All,
I have a task of migrating a 500GB single instance database to a two-node RAC database with a little downtime at hand. My migration strategy is to:
1) Create a RAC physical standby for the Single Instance database
2) Switchover to RAC standby.
Primary and Standby OS and DB configurations:
OS: Windows Server EE 2003 (64-bit)
DB: Oracle 10g Database Release 2 (10.2.0.4)
Oracle 10g Clusterware Release 2 (10.2.0.4)
To create a RAC standby, I will:
a) Install Clusterware (10.2.0.1)
b) Install Database (10.2.0.1)
c) Patch both Clusterware and Database (10.2.0.4)
d) Create ASM instance for both the nodes (+ASM1 & +ASM2)
e) create standby controlfile on primary
f) Move standby controlfile, RMAN backup of primary, pfile, listener.ora, tnsnames.ora, password file to standby host-1
g) make necessary changes to the pfile on standby host-1 like cluster_database, instance_name, thread, ...
h) mount standby database and restore backup
Kindly validate my steps and if there already exists such a document then please do provide me with a link.
Regards

Can we use Grid Infrastructure 11.2 to protect a single instance database?

Hi all,
I would like to use Oracle Grid Infrastructure to protect a single-instance database.
I found these docs:
http://www.oracle.com/technetwork/products/clusterware/overview/em-db-failover-128585.pdf (for 10.2)
http://www.oracle.com/technetwork/products/clusterware/overview/si-db-failover-11g-134623.pdf (for 11.1)
I was unable to find a similar document for GI 11.2 . Do you know if such a document exists?
At the moment I only know that the GI is free if used for an Oracle Product, but I am not shure whether it can be used to protext external applications or single-instance databases
Andrea

Hi,
while this still works (the scripts for failover you find in the demo folder $GI_HOME7/crs/demo/coldfailover), the document does not exists, since with 11gR2 there is a supported solution called RAC ONE Node, hence rendering the manual setup obsolete.
For more information see:
Oracle Clusterware and Application Failover Management (Doc ID 790189.1)

Configuring multiple services in a single instance database

Dear All,
I would like to create multiple service names for a single instance oracle database (10.2.0.3 on IBM - AIX 6.1). I tried searching on the net, reading documentation, and also on the metalink but couldn't find anything relevant to single instance database.
Say I have two users, userA and userB, for which I would like to use two services (ServA and ServB) to connect to the same single instance database.
Any help in this direction is appreciated.

Thanks for your quick solution.
By the time you answered I was able to locate it in the documentation. I have tested it and its working perfectly. Here's the documenation link.
http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/initparams188.htm#i1133481
It is very hard to believe you didn't find this in the documentation, and my suspicion is you didn't search for it at all.It is very hard to believe that you don't trust others and end up in suspicion. I wish you were sitting next to me while I was searching for the link/document.It is because the vast majority of doc questions are asked by people who don't read the docs at all.
Now, I'm curious about your requirement. While it can be done, it is pretty unusual. That always leads me to want to step back from the technical question and ask What business problem is this solving?

Single-Instance ASM to RAC ASM !!

At the moment i am in process to create a RAC ASM instance on two nodes. When i was creating ASM instance it gave me error that unable to connect to crsd on Node2.
So i manually added asm instance using srvctl on node2. It is registered with CRS but it is not online. I tried starting up by using crs_start or srvctl start asm but asm resource is down on both the nodes.
I have started up manually both the ASM instance and created some Diskgroups, Now i have to create a RAC enabled DB for which it is showing convert single-instance ASM to RAC ASM.
What needs to be done.

Hi
because the service ASM was added individually the crs stack is unable to recognise the clustering of ASM. In fact this has just made the ASM on two nodes function as two seperate ASM instances. They were never clustered. So i think convertion is one option. I came here while looking for one such doc. My 10.2.0.1 RAC install on windows 2003 went on a toss.. while dbca was trying to set up the clustered ASM and configure the instance, the primary node crashed and when it was recovered, i could notice the ASM instance is created on one node only.. When i try to invoke dbca again, neither am allowed to create an ASM instance for RAC/convert the existing one to RAC. Until now what I have found is that if such case arise, the quicker way is to revert everything back, clean up the server of clusterware and re install every thing... but before am looking for my options..
does any body have an idea? please share

Converting Single Instance database into Oracle Fail-Safe on Linux

Hi All,
We have single instance Oracle10g database running on Linux RHEL4. We are looking to convert this database into Oracle Fail-Safe (Active-Passive). Does any one have document for Oracle fail-safe setup?
Regards,
Tushar

Tushar,
you can't use software for windows on Linux.
However, there's number of ways to implement high-availability solution on Linux Oracle.
You can go with Active-Active (RAC) - which means that you'll have two servers attached to the same database at the same time. You can use either, and if one goes down(due to power failure for instance), the second will still be available.
You can go with Active-Passive (Data Guard) - which means that you'll have one of the nodes being active and the second passive, but synchronized with the first one, so in case of failure of the first node you can activate the second one.
You can also go with linux clustering - which is most similar to MCS + fail-safe - you'll have two nodes clustered with linux clustering software (RH cluseter suite for instance) and connected to shared storage. One node is active, and in case of crash database instance will be automatically started on the second node. This is beneficial because you can use your resources more efficiently. In case if you have two databases you can run each of them on dedicated server and then, in case of node failure move to another one. However, the setup of such configuration is quite cumbersome.

Creating a new single instance on a RAC structure

I have a RAC with 2 nodes using ASM, it's perfect running.I don't have any problems with that.
Now I need to create a new instance in one of the RAC the nodes.
So my question is, I need to create a new ASM instance for this new single instance that I will create?
What will be the best practice in this case?

But i will have to create a new ASM instance to control the storage of this new instance?
I have the ASM1(node 1) and ASM2(node 2) I will have to create de +ASM3 on the node 1 to control this new instance?

Do we require HBA card for single instance database.

Hi All,
I have doubt that we are going to implement a single instance with ASM.
Db version will 11gR2 as it is asm. My concern HBA is required for single instance oracle database.
Please suggest.
Thanks and Regards,

The question is : do you want your user to be able ti use their application offline ?
If yes, then you may provide them a local database and use a JDBC type4 driver. (The application is fetch directly from the server when first connected and then is able to lauch the applicaiton off-line) Such a network listen is allowed by the JNLP security model without any application sign !
If no, then why not having a single database and some user debedant table that store the user specific data (as usual), and using a login dialog-bon (or an auto-logon mechanism) to restric identify and access your database thru some business logic via RMI or any ligh-webservice technology.
Anyway you have plenty of solutions ..... it only depends of what are the exact needs.

I doubt Oracle 10g R2 , is certified with CentOS !!!

It is good,to install patch set 10.2.0.3 , before setting DG.
