Multiple Single Instance DB Conversion to Cluster Database RAC
Hi,
Good Day.
we are in planning phase to perform an activity, in which 8 existing (Single Instance) and 1 new database will be consolidated in ONE Oracle RAC Cluster database.
Kindly share your ideas, to perform the consolidation smoothly with minimal downtime.
can any one share the cons/pros, what if we create MULTIPLE RAC cluster databases instead of one cluster database?
Thank You.
Regards,
The cons are pretty much the same as running multiple instances on a single server: Tuning will be much harder because you will have to look for bottleneck and depletion of common resources (CPU, RAM, IO) across all your instances instead of one (where you have lots of nice and integrated features). There is the potential for contention between resources and since each instance/database has its own SGA (and they are not shared) you will potentially waste a lot of ram for stuff that is redundant between the instances.
But if you still think this is something you want to do, you should take a look at the 'server pool' feature. It will give you some more control over how your databases/instances should be ditributed across your rac (there is propably no need for all databases to be running on all servers at the same time)

Duplicate single instance (11.2.0.2) database to RAC (11.2.0.3)
Hi Experts,
I have to duplicate my PROD database which is a single instance in to RAC TEST database. Please give me procedure to do that.
Prod database - Single Instance - 11.2.0.2
TEST Database - Need to create dummy instance in RAC and restore the PROD data - 11.2.0.3
Note: RMAN duplicate failed due to different patch level.
Regards,
SalaiYou CAN restore an 11.2.0.2 database backup into an 11.2.0.3 ORACLE_HOME. You will need to upgrade the database (data dictionary) using catupgrd.sql from the 11.2.0.3.
Conversion to RAC will be done after completing the upgrade. Essentially, this consists of adding one more Redo Log Thread and one more Undo tablespace.

Single Instance 10.2.0.1 Database using 10.2.0.4 ASM
Hi,
I have ASM running from one ORACLE_HOME1 which is upgraded to 10.2.0.4 version.
I want to install new 10.2.0.1 database in another ORACLE_HOME2 which uses ASM storage from ORACLE_HOME1.
Is this supported? Is it possible to place 10.2.0.1 DB on 10.2.0.4 ASM storage while installing?
Thanks,
RahulHi,
Yes i think its will support.
May i know is there any specific reason that you want to install new oracle_home(10.2.0.1)

CloudControl 12c: when adding cluster-database single instances are missing
Hello ,
I'e have installed the agent 12c on every single host of our RAC. When adding a database to CloudControl 12c just the RAC-instance gets discovered - but not the single database instances on each host.
Due to this when clicking targets -> databases I just see the cluster-database - but not every single instance of the database.
Compared to another RAC database this is totally different behaviour.
Any help will be appreciated
Rgds
JHHello ,
maybe I should try to explain the issue a little bit clearer...
We have one RAC database called PROD02. When clicking "targets -> databases" I see the following:
PROD02 of type Cluster Database
PROD021 of type Database Instance
PROD022 of type Database Instance
That's the way it shoudl be - that's the way I expected it...
For the newly cofgured RAC database, called PREP02, it looks different when clicking "targets -> databases"
PREP02 of type Cluster Database
The single instances don't show up. Of course I see the single instances when clicking on "PREP02" under the item "Instances".
Now I wonder why these two RAC databases are differently displayed when clicking "targets -> databases". When trying to add the single instances (clicking "Add" under "targets -> databases") and selecting then either "only on the host <hostname>" or "on all hosts in the cluster" no single instances are found or displayed...

Single instance standby for 2-node RAC
Hi,
Oracle Version:11.2.0.1
Operating system:Linux
Here i am planing to create single instance standby for my 2-node RAC database.Here i am creating my single instance standby database on 1-node of my 2-node RAC DB.
1.) Do i need to configure any separate listener for my single instance standby in $ORACLE_HOME/network/admin in ORACLE user or need to change in Grid user login.
2.) Below is the error when i am duplicating my primary 2-Node RAC to single instance DB. And it is shutting down my auxiliary instance.

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
Please see:
Minimizing Downtime During Production Upgrade [ID 478308.1]

Hi,
We are in the process of consolidating several databases on a single instance of SQL Server 2012.
Databases are developed by outside vendors; they have to be able to install and support their databases but they shouldn't be able to do any thing with the other databases.
When I tried to migrate the first database, the vendor told me that on the former server he used the sa account in some batch.
On a previous thread
https://social.technet.microsoft.com/Forums/sqlserver/en-US/dc1f802f-d8de-4e2b-87e5-ccb289593fb7/security-for-multiple-applications-on-a-single-sql-server-2012-instance?forum=sqlsecurity
it was suggested to me that I create a login for each vendor and that this login should map a user in their respective databases.
To test, I simulated the process in a test database:
1 - I create the login and I scripted the command:
USE [master]
GO
/* For security reasons the login is created disabled and with a random password. */
/****** Object: Login [M02_Test] Script Date: 2014-12-02 16:23:58 ******/
CREATE LOGIN [M02_Test] WITH PASSWORD=N'ÈS^y¡¶=Å€"+y¤j|úªhÖféÎЕœEu
c', DEFAULT_DATABASE=[M02], DEFAULT_LANGUAGE=[us_english], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
GO
ALTER LOGIN [M02_Test] DISABLE
GO
2 - I create the user and scripted it
USE [M02]
GO
/****** Object: User [M02_Test] Script Date: 2014-12-02 16:29:41 ******/
CREATE USER [M02_Test] FOR LOGIN [M02_Test] WITH DEFAULT_SCHEMA=[dbo]
GO
Questions:
What should we do with te scrambled password: is it saved as it was entered and should it be kept somewhere in a safe place?
Would that do the job for the vendor who used sa before?
Thanks for your adviceI'm not sure why you would save the script. Why not create the login, in one way or another give the vendor the password. Keep the login disabled until needed.
I don't recall exactly what we said last time, but it occurs to me that the application setup things on server level. Jobs is the prime thing that comes to mind, but there could be other things.
Now, here is an important observation. As long as the vendor's application was alone on the server, that was OK, and it was OK to give the vendor sysadmin rights. In this situation this is less OK, and as we said, you should only give the vendor db_owner
in the database.
But the vendor will need to tell you what they do on server-level. They should know this - unless they sell their app as a "alone-on-a-server application". (And there are indeed such applications out there, even from Microsoft.) But there is a
risk that they will bill you extra if you make their installation more difficult.
Maybe you will have to give some vendors sysadmin for the installation, but in such case, you should ask them why they need it. If they don't, give them db_owner, and they will have to find out their hard way. (And you don't pay them for learning
their own application.)

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? -
Multiple ASM instances using single cluster install - Is it possible??
Hi,
I have 2 node RAC cluster installed on Linux. All the storage is on EMC. I need to setup another environment using HP storage on the same hosts. Is it possible to created second ASM instance using the same cluster install?? I wanted to have clear separation b/w EMC and HP environments and that's wondering if it's feasible to do that.
Haven't tried it yet to see if it complains.
Thx
AnithaAnitha,
The data migration won't happen (at least not aggressively) until you do step 2 in your list where you remove the EMC disks. That removal operation will take a long time as Oracle will have to move the data before it can complete the operation. If you want to be sure, I'd recommend creating a new disk group with one of your new disks, put a small tablespace in it, create some data in it, then add a disk to that new group and remove the original disk. Then you'll have some confidence in the procedure and verify that it works without risking your production data. After you test, you can drop the disk group and use the disks for their intended purposes.
To answer your question, yes, that's the process exactly as I suggested it above. Should work fine--but will probably take a while to do the remove, so be prepared to leave that running for quite a while (i.e. don't expect to close the terminal and go home right after running the remove).

Can there be multiple ASM instances on single node?
Hi,
Can there be multiple ASM instances on single node?
This one says No : http://www.freelists.org/archives/oracle-l/02-2008/msg00317.html
And This one says Yes : http://www.databasejournal.com/features/oracle/article.php/3571371
Thanks in advance.
Thanks,
Harsha
Edited by: user498756 on Sep 11, 2008 2:23 AM...that document doesnt say you cannot have multiple ASM instances on a node. It says "...ASM, +you only need one ASM+ instance for that computer, to manage the two database instances that use ASM."
The fact that you only need one - and I cannot think of a good reason to have more than one - does not preclude the fact that you do seem to be able to have multiple ASM instances on a single node, each looking after its own set of disks and diskgroups.
Again - I cannot think of a good reason to do so though!

Multiple ASM Instances on single node
Hi All,
After going through some threads it seems to me that multiple ASM instances on a node is not supported and recommended by ORACLE but i coudn't find any ORACLE document or support matrix mentioning this. Can any one give me a pointer to this. Please correct me if i am wrong and Multiple ASM instances are fully supported by ORACLE.
Thanks,Multiple ASM instances on a single node are supported but not recommended due to several issues you could encounter during that kind of configuration.
Possible interraction between those instances for identification of each disk area usage,each disk area permissions , database instance to asm instance mapping and so on, could result in unwanted behaviour, as ASM is in some way just oracle's representation of LVM.
Intention is that any kind of distinction/separation of oracle related data under the ASM should be done through the disk groups.
So it seems it would be better to apply this kind of logic rather than doing suspiciously magical and rare configurations that could bring you similiary strange and unexpected problems. -
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. -
How does a RAC DB 'spread' from single instance to multiple instances ?
GI/RDBMS Version: 11.2.0.3
OS: Oracle Linux 6.3
Filesystem : ASM
When a RAC database is created using dbca , Manually , or RMAN restore, the DB is created in the Node1 first with cluster_Database=FALSE .
Then you run the following commands (for 3-node RAC) from Node1
srvctl add database -d lmnprod -o $ORACLE_HOME -p +LMNPROD_DATA01/lmnprod/spfilelmnprod.ora
srvctl add instance -d lmnprod -i lmnprod1 -n hwcarser290
srvctl add instance -d lmnprod -i lmnprod2 -n hwcarser291
srvctl add instance -d lmnprod -i lmnprod3 -n hwcarser292
Once the DB is created,mounted and opened in Node1 and the above commands are executed , you set cluster_Database=TRUE and startup the Instance2 and Instance 3 in Node2 and Node3.
I just want to know how does Node2 and Node3 becomes aware of the DB and joins the DB cluster ? What happens internally ?Generally speaking, registering in OCR is not required for database to be a cluster database.
Migration from single-instance database to cluster consists of creating redo logs and undo tablespace for new instance and enabling this instance (thread). If database is policy-managed, this is done automatically for new node. -
10.2.0.4 patch on single instance standby database
Hi All,
We have production database 10.2.0.3 running with RAC having 2 nodes on Solaris 10. We have patched this
databases to 10.2.0.4 (both nodes) on production without any issue.
We have a physical standby database (10.2.0.3) with 2 nodes on solaris 10. But we have stopped node2 sometime
back and currently it's a single instance standby database. Whe nwe are trying to apply patch to standby dataabse
it's showing both node during installation and installation fails when it tries to search for node2.
What's the solution for this problem? Any document on how to patch the single instance standby database when
production is running in RAC.I think you are basically saying that you have a 2 node RAC cluster with 1 node down (possibly permanently) and you want to just patch 1 of the nodes?
It's not overly a surprise the installer is trying to patch the other node, when as far as your inventory is concerned you have a 2 node cluster.
Have you tried running the installer with the -local option?
This should just patch your local node. Obviously the dictionary changes will get applied via MRP from the primary db.
