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

Hope this helps
thanks,

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.

Oracle 11gR2 RAC (convert single instance to RAC)

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:

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)

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.

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.

Oracle provides following methods to convert a single instance database to RAC:

DBCA
Manual
RCONFIG(from 10gR2)

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.

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?

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.

Please let me know if have any good doc.
thanks

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.

11gR2- webutil upload file to AS on two nodes RAC?

Hellow experts plz help with the following issue,
we are using 11gR2 forms on two node rac,webutil configured on both nodes. upload/download files to AS folder(UP_FILES) using our forms. node 2 is actually replica of node 1(forms,reports,UP_FILES). we are now facing a problem that the form which upload file to AS, only upload that to the node from where it is running say if it is running from node1 then it upload files to folder UP_FILES on that node( as the entry in webutil.cfg file) but we want that UP_FILES folder should be synced with each other on both nodes and a form running whether from node1 or node2 upload the file to both nodes at time.
How this will be accomplished?
--------webutil.cfg entry
transfer.appsrv.read.3=D:\UP_FILES
transfer.appsrv.write.3=D:\UP_FILES
-----FORM UPLOAD CODE
      IF :CONTROL.FILE_LOC IS NOT NULL THEN
        acyr3 := :CONTROL.TXTVOUCHERNO||'-'||acyr2 ;
       FILE_RESULT := WEBUTIL_FILE_TRANSFER.CLIENT_TO_AS_WITH_PROGRESS(CLIENTFILE=>:CONTROL.FILE_LOC,
       SERVERFILE =>'D:\UP_FILES\'||acyr3||'.PDF',
      PROGRESSTITLE=>'UPLOAD TO DATABASE IN PROGRESS',
      PROGRESSSUBTITLE=>'PLEASE WAIT' );
      END IF;
--FORM DOWNLOAD CODE
        FILE_RESULT := WEBUTIL_FILE_TRANSFER.AS_TO_CLIENT_WITH_PROGRESS
             CLIENTFILE=>'D:\UP_FILES\'||acyr3||'.PDF',
        SERVERFILE =>'D:\UP_FILES\'||acyr3||'.PDF',
      PROGRESSTITLE=>'DOWNLOAD FROM DATABASE IN PROGRESS',
      PROGRESSSUBTITLE=>'PLEASE WAIT'
             CLIENT_HOST('rundll32.exe url.dll,FileProtocolHandler D:\UP_FILES\'||acyr3||'.PDF');
             IF FILE_RESULT THEN
message('File downloaded successfully from the Application Server');
END IF;

Well, you're uploading the file to one node, so this is no surprise. What you can do is to store your file on a shared folder (which might be a bit tricky on windows) or synchronize a folder between your nodes. Unfortunately Forms can't access ASM directly (assuming you are using ASM), so you can't store your files directly in ASM where it would be accessible from both nodes.
