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.
Regards

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.

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?

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

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.

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:

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.

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.

Request help for confusion over Oracle single instance database

Hello all,
Following Oracle version was installed at the client site @ the moment
Oracle Database 11g Release 1 (11.1.0.6.0) for Microsoft Windows (x64) on Non-Clustered enviornment.
The clients are going to arrange another identical server and wants to configure it with 2 nodes windows cluster enviornement.
The current server where Oracle server was installed will become active node of the cluster.
The confusion is if we should install the following version on node 2
Oracle Clusterware 11g Release 1 (11.1.0.6.0) for Microsoft Windows (x64)
or
node 2 should also be installed with
Oracle Database 11g Release 1 (11.1.0.6.0) for Microsoft Windows (x64) version ?
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/111060-win64soft-099656.html
Any help for removing confusion would be appreciated
Thanks,

I think it's first needed to think about what kind of configuration you want; Failsafe, DataGuard or even RAC? But you talk about clustered and an active node, so I take it the object is to create a Failsafe cluster.
If you want to use FailSafe first read about it, for example use http://www.oracle.com/technetwork/database/windows/index-082893.html (Resources: Documentation)

Single-instance manual standby for a three-node RAC database

Hi all,
I am wondering how it is possible to create a manual standby database for a rac primary database.
Oracle versione is standard edition 11.1.
I have experience creating and managing manual standby for single-instance database; I am wondering if and how I can instruct the single-instance standby database to discover and apply the three redo threads that I will copy from the primary site to the standby site.
Should I use rman to catalog all the archived log on the standby site ?
Should I configure many LOG_ARCHIVE_DEST_n parameters to point to many different path, one for each primary instance (i.e. one for each redo thread), and let rman automagically discover all the archived logs ?
Should I configure only LOG_ARCHIVE_DEST_1 , put archivelogs from all threads in the same folder, and let rman automagically discover all the archived logs ?
Thanks for every answer!
Andrea

Hi,
indeed i catalog all transfered archive logs in front of the recover process.
During the tests i believe (iirc) i was unable to recover from transfered archivelogs without catalog them first. But this statement is out of my mind, i am not 100% sure for this, sorry.
Some more details.
Because it is a standard edition, i have to use on the RAC side ASM. So our normal scripts to transfer archivelogs from primary to standby are obsolete.
So i decided to put the whole standby thing into the database. Now the primary database uses external scheduler jobs to do the work. The standby side is not using ASM, so there is no need to handle the logs in any special way.
The steps are:
1. Get SCN from primary and standby
2. Transfer the logs for the gap from ASM to "normal" filesystem.
3. Transfer (and compress, if not in LAN) to standby archive dest
4. Catalog on standby side
5. Recover on standby side
6. Delete on normal filesystem (on both sides, but on standby with a delay of 2 days just to be sure)
The steps on the standby side are both using the primary scn from step 1 as a parameter to avoid error messages during the catalog or recover call.

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.

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?

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.

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
