Migrating single instance SAP and Oracle 11.2.0.1 database to Oracle RAC

We have a single instance SAP Netweaver environment on Oracle 11.2.0.1 database and want to migrate to Oracle 11.2.0.1 RAC and ASM. The documents are for 11.2.0.2 and later but we want a way to:
1. Migrate single instance SAP and Oracle 11.2.0.1 instance to ASM
2. Configure the environment as four node Oracle 11.2.0.1 cluster
Thus far, I have:
1. Installed clusterware 11.2.0.1
2. Installed four ASM instances
My questions:
1. We want to migrate the single instance database to same server and extend to four node cluster and ASM
However, current SID for SAP and Oracle must remain the same. The problem I have is that the target database name needs to be same as source on same physical host.
2. How would I use RMAN to migrate the single instance database to ASM for 11.2.0.1?
3. How would I use rconfig after this step?

2- We have four available Oracle 11.2.0.1 ASM instances on four RHEL5 Linux hosts
3- We have installed four node Oracle 11.2.0.1 clusterware on the above nodesAnd what is the shared storage? For RAC, all shared storage devices for the cluster need to be available and usable by all ASM instances in that cluster.
Issue- we have RAC 11.2 clusterware listener using SCAN and listeners for all four clusterware nodes.
When we try to run the following RMAN command to migrate the single instance Oracle 11.2.0.1 datafiles it fails:The failure says: "+RMAN-10038: database session for channel ORA_DISK_1 terminated unexpectedly+". And this in itself does not tell you what the actual problem encountered is.
4- How to register the single instance with all four ASM instances and network services to resolve the above issue?Register what instance? ASM does not need databases or instances to be registered. It is a storage management layer. The cluster (grid infrastructure) layer is the one that deals with the registration (and management) of the various services and resources on that grid (e.g. ASM instances, database instances, SCAN and VIP, Listener services, etc).
5- Do we need to first run rconfig utility against single Oracle 11.2.0.1 instance to register with clusterware services BEFORE using RMAN to perform the datafile migration to ASM?Never used rconfig. See Support Note +RCONFIG : Frequently Asked Questions [ID 387046.1]+ for details.

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 fails for migrate single ASM instance to Oracle RAC 11.2.0.3

We completed the following steps thus far to migrate single instance with ASM 11.2.0.3 on Oracle Linux to RAC:
1. Install RAC CRS 11.2.0.3 in GRID_HOME
2. Install RAC database 11.2.0.3 software in new ORACLE_HOME
3. Added ASM diskgroups to two node ASM instances
4. run rconfig from target RAC ORACLE_HOME
It fails on:

Has anyone seen this issue before with migrating with rconfig and if so, how did you resolve it?

good to know. thanks for updating the thread with what was wrong, this will help the community if someone faces this issue.

How can I stop the shared mode service after install a single instance DB ?

I installed a single instance DB and don't use the dispatcher ,
is there a way to stop the service as below?

Error initiating process in single instance mode

We have implemented Guided Procedures and have included a visual approval step to review an employee's supporting documentation before an Admin makes changes based on the approval request, and also KM documentation steps and iViews. Lately in the Alerts monitoring area I am seeing multiple errors.
I have checked the callable objects and all pass the check (including input and output parameters, results states, process exceptions and configuration parameters) however the error keeps showing up. Within the process instatiation tab the process is set to 'single running process is permitted for each user'.
Does anyone know what may be causing these alerts, and how do you repair them?
The full alert is below:

Hello,
The GP SingleInstanceProcessException is normal when using
Single instance process instances which for example ESS uses.
If you have single instance processes and you try to start an already
started instance, the exception will appear but will not cause problems.
It notifies the UI to redirect to the previous process instance.
It is expected behaviour.
Thanks and best regards,

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:
- Shutdown the instance which is cloned to non RAC.
- Shutdown all the listeners.
- Rename following file in %ORACLE_HOME%/bin directory: orarac10.dll to orarac10.dll.bak
Give me your thoughts, there is nothing on Metalink....

Restoring RAC database to single instance

We run a 2-node RAC instance on 11g (Standard Edition) under SuSE 10 but our remote disaster recovery machine just runs a single instance.
Is it possible to restore from RMAN in this case and how should we go about it?
Thanks!

It is always possible to restore a RAC database backup to single instance. Infact restores are generally made to a single instance. After the restore we convert the database to RAC with required number of instances. Depending on the procedure you use the steps vary.

Single DB Engine and multiple DB Instances approach

Hi Tech Arch gurus,
Need some advice from all of you. We are currently planning to install SAP training systems to latest versions.
We are getting recommendations to goahead with Dedicated host for Oracle Installation where we have Single DB Engine and multiple DB Instances for all different 7 SAP Servers (ECC6, CRM7, BI/NW7.3, SOLMAN7.01, SRM7, EP/NW7.3, PI7.1).
Certain things that need to be clarified before we go ahead with this:
1.     How complex/simple is this approach ?
2.     If there are some issues noticed in the future (Performance issues etc) in this landscape , how much effort will be required to migrate out a DB instance for an SAP product to another machine. We would be having both ABAP and Java stack for our systems.
3.     We would later plan for adding some more systems into the landscape like SAP MDM, SAP CE, SAP BPC etc. If we add all these systems with a single DB engine, would there be performance issues etc. (We are operating under assumption that underlying hardware of the DB engine will be powerful enough)
Can you please provide some expert guidance on this approach?
Your response would be much appreciated.
Thanks,
MD

As a consultant I never dared to do different from what SAP says in guides or notes, at least when it comes to PRD systems.
For QA and Test Systems, discussions might be needed with the customer, depending on how important these systems are,
and for sandboxes I already did some stuff, that will even scare some Oracle guys
As Stefan says, the technical setup is not that complicate at all.
But I never had to fight for a support call in a non-supported Environment, so I can't say.
I always decided to be on the safe side.
If you have your Oracle License directly from Oracle you might disscuss such special support issues with these guys.
The problem is: If you get a call, and the first level support guy from SAP spots the non-supported environment, it MIGHT be possible that you need to escalate and may be pay for the support, but I suppose they will not let your system die
May be some of the SAP moderator guys can throw a comment in on this.
