Single Instance to RAC on P570

I am looking for some help in the form of a best practice or how to document for migrating a single instance Oracle Env from HP-UX (I think it is HP Unix) to a multi-Node RAC Env on IBM P570 series servers. Current version is 9i and we will be going to 10gR2 and then potentially to 11g as well. I understand when going to P Series Servers that there are several considerations.

That's the easiest option. It will require the most down time when compared to others. Depending on the size, database, and requirements, it might be a viable option for you. Normally the amount of downtime required would not make it an option in most large shops.
I'm not sure why you would need to do any conversion to RAC after. You can directly import to a RAC database.

Convert single instance in Rac

Hello experts, I have already configured a cluster database between two nodes with a RAC database named Cars. Also I have a single instance database named Persons in the first of the nodes. Now I need convert this single instance(Persons) in a Rac database, that is I want to have two RAC database(Cars and the new Persons).
Thank you very much in advance.

Adjust parameters from single instance to RAC

Hi
I am carrying out a migration from single instance to RAC. I know there are a list of parameters that We have to adjust to keep the same or better performance moving from single instance to RAC. Can you post any link or something like that, that help to adjust the parameters ?
Thanks

How to convert from single instance to RAC?

Hi, I have one environment it is version is 10.2.0.4 in linux SUSE.
I decided to move this environment to 10.2.0.4 Real applicaiton cluster has two nodes in linux red-hat.
Firstly,
I install 10.2.0.1 rac on two new machine in linux red hat.
Then I upgrade my rac to 10.2.0.4 from 10.2.0.
Now I want to move the single instance to RAC,
Is there an anathoer way that different from export , import?

Besides the obvious Export-Import which do not want to consider (although it would be the neatest method !), look the 4th conversion scenario under paragraph D.3.2 "Single-Instance to RAC Conversion Scenarios" at
http://download.oracle.com/docs/cd/B19306_01/install.102/b14203/cvrt2rac.htm#BABFCAHF
The 4th conversion scenario is "Converting a single-instance Oracle Database 10g Release 2 (10.2) to an 10g Release 2 (10.2) RAC database, running out of a different Oracle home, and where the host where the single-instance database is running is not one of the nodes of the RAC database".

Migrate from single instance to RAC manually

Hi,
I have a 10g database running in single instance.I have installed grid 11.2.0.2 in two nodes including the node where current instance is running,I have installed 10g again in a seperate mount point in both the nodes .It has the same patches as single instance 10g home.Now how to migrate from single instance to RAC manually.
Thanks,
Sekar

-restore this database into 11g ASM if its not already on ASM.
-upgrade this database to 11g from 10g on single instance.
-Now Converting Single Instance on a Cluster to Oracle RAC ,here you have different option to perform this once its 11g database after upgrade.
using rconfig
using dbca or manually.

Convert ASM single instance to RAC ASM instance...

Hi, all
Im installing OracleDatabase with RAC and I got an error on the Database Configuration Assistant that says "The ASM instance configured on the local node is a single instance. To manage this instance as a single-instance ASM restart DBCA and select the single instance database option. To manage this instance as RAC ASM, convert it to RAC ASM first".
How I can convert it??
Thanks

See the link below for converting a single instance ASM to RAC ASM. The link is to the Oracle® Database Oracle Clusterware and Oracle Real Application Clusters Installation Guide for Linux. If your platform is not Linux, check the Install Guide for your OS.

Migrate single instance to rac

Hi all
Currently i have installation Oracle SE (10.2.0.1) i want migrate to rac 2 x Oracle SE (10.2.0.3) ?
Can i use RMAN? or i must use exp/imp ? i have difrent version of oracle so i dont knew
Thanks

Hi,
well there are two ways to do that.
A) use the existing infrastructure and the database and adding additional nodes.
B) setup up new SYSTEM/HARWARE RAC environment and move single database instance to RAC.
which OS you are using.
why dont you upgrade your ORACLE or you can make use to transpotable tablespce also.

Rconfig: converting a single instance to RAC instance

Hi,
I am trying to use the "rconfig" utility to convert a single instance to a RAC instance in an existing RAC cluster.
I have modified the .xml file, and am trying to run the conversion from the 1st node in the 2 node cluster (where the single instance resides).
The only error message i seem to be getting is below:
<Response>
<Result code="1" >
Operation Failed
</Result>
<ErrorDetails>
ORCL_DATA_ORCLCLN The specified diskgroup is not mounted.
</ErrorDetails>
</Response>
</Convert>
</ConvertToRAC></RConfig>
Now I dont really understand why I would be getting that message as the instance is up and running and ASM disk group is mounted on node1 at the time i run the rconfig command, though its not clear to me if I also need to somehow mount the ASM disk group on the second node prior to running the rconfig command??
node1:
bash-3.00$ asmcmd -p
ASMCMD [+] > lsdg
State Type Rebal Unbal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Name

node2:

State Type Rebal Unbal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Name
I have attached the output of the alert log during the rconfig conversion of the target database, but it all looks pretty standard to me (keep in mind i am an oracle novice!).

IBM's GPFS for REHL4/5 and a single instance (non RAC) 10gR2 environment

I've looked high and low for a clear support statement of IBM's GPFS for RHEL4 or RHEL5 in a non RAC 10gR2 implementation. Does anybody have a pointer that would explain Oracle's support or lack there of?
Thank you,
Martha C.

For RHEL O/S level issues, there would be no support. You would need a ULN support license for generic O/S questions and you would need to switch to OEL.
For non-ULN customers with a database CSI, O/S level support is provided only on issues specifically related to the OCFS2 or ASMLib packages; for generic O/S questions you would need a ULN license.
Perhaps folk over in the DATABASE forum could clarify Oracle's RDBMS support policy for this environment, but succinctly: no O/S support without a ULN license, subject to directly-related OCFS2/ASMLib issues.

Restore single instance rman backup to rac database

Hello all. I have a 10gR2 single instance database that I have been taking backups using the oracle's suggested backup strategy, that is, once full database backup and incremental backups here and there. That's is all fine as I have (many times) being requested to rollback the database resulting in all operations being sucessfull.
However, since this is somehow a pre-certification database, I am now being tasked to restore this database to what is going to be our production database, which is a 10gR2 rac database. I have already set up the RAC database sucessfull.
Now, my question is: How can I take one of the backups that I have on the single-instance database and restore onto my RAC database ?
Some information about the infraestructure:
Both operating systems are HP-UX. Single instance is 11.23, RAC database is 11.31.
Both database are using ASM as datafiles storage and flash recovery area storage.
Any help will be appreciated!
Thanks!

In general terms, there are several ways you can convert a single instance into a rac intance, and it involves much more activities than just adding redo threads.
Use of DBCA
Enterprise Manager Grid Control
rconfig utility
Considering your case, if you don't currently have Grid Control, the first option is rconfig.
1. Migrate your database from the current environment to the target environment by a regular cloning procedure, this will create a single instance into your rac environment. Your regular rdbms rac installation allows you to manage both, single instance and rac instances. Use this procedure to clone your database to the target RAC environment using recovery manager --> http://madrid9999.googlepages.com/rmancloneadatabase
2. Once you have started your database in the RAC environment proceed with the rconfig tool, this requires some files to perform the conversion, the ConvertToRAC.xml file which is located at $ORACLE_HOME/assistants/rconfig/sampleXMLs
3. Once you copied/edited the ConvertToRAC.xml file, you have to run the rconfig. Save the ConvertToRAC.xml under a different file name.
rconfig editedConvertToRAC.xml
4. For further reference on the rconfig command, you may refer to this page Oracle® Real Application Clusters Installation Guide

CONVERTING TWO NODE RAC ON WINDOWS TO SINGLE INSTANCE

I got question about a two node RAC on Windows.
One of our vendors is hosting our oracle enviroment and we are planning to bring in the datacenter in house and manage it ourselves.
Current they have a two node RACon windows
The new enviroment we are building here , we want to get rid of RAC and bring it back to a single instance environment.
How do i approach this?
1. My first option was to create a new database server and do the export dp from one of the node and import to the new single instance enviroment.
My conncern is can you do export from RAC database and import it to a non RAC enviroment?
2. My second option is to delete one node on the two node RAC and then do export dump or cold backup and copy the database files and necessary config files.
let me know how i can approach this.....

Okay guys after digging aroung i found the following approach.....
Cloning Oracle 10gR2 from RAC Environment to Single Instance Environment will raise the following error
ORA-29702: Error occurred in Cluster Group Service Operation.
The new instance is looking for CRS on new single instance non RAC environment.
For UNIX platform follow the following steps:
- Shutdown the instance which is cloned to non RAC.
- Shutdown all the listeners.
- Relink Oracle executable with rac_off option.
$ make -f ins_rdbms.mk rac_off
$ make -f ins_rdbms.mk ioracle
- Remove all the parameters from init.ora which points to second instance
and it is on other node.
- Remove cluster_database parameter
- Remove undo_tablespace parameter which points to second instance
For Windows Platform follow the following steps:
