Convert 11gR1 to RAC using 11gR2 GRID

Hi everyone,
I have the following scenario.
I have 2 servers running RHEL 5: server1 and server2
on server1 I have an active database running 11gR1 single instance.
I'm going to install 11gR2 GRID across server1 and server2.
Then migrate the 11gR1 DB on server1 into ASM.
My question is, if I want to create a second instance on server2 can I install another single instance 11gR1(software only) and do the necessary RAC conversions or will I have to do a new 11gR1 cluster DB install across the 2 nodes and do RAC conversions then?
Thanks in advance.

Well mate, for once, you should've known that a RAC is not created by plugging two single instances together and then rebooting the machine, vrooooommm you go.... No, it doesn't work that way... You gotta do some good reading....
I guess you need to have your final configuration as
Clusterware + ASM - 11gR2
Database - 11gR1
Below are the likely steps to acheive it:
Backup the current 11gR1 database
Set up 11gR2 cluster using the two nodes
Do 11gR1 oracle binaries cluster install
Startup ASM isntances on 11gR2 clusterhome & configure disks.
Using the newly installed 11gR1 binaries on one of the nodes, restore/move the database backup taken in the first step to use ASM
Convert the single instance 11gR1 database (running on new 11gR1 binaries) with ASM to RAC. - Suggest doing manual conversion than using dbca for better control.
Cookbooks available in metalink and clear procedures are available with a simple search on oracle documentation.
Cheers.

How to install Oracle RAC using 11gR2 on Win 7 32 bit from scratch?

Hiii,
I am a fresher and I have a win 7 system 32 bit with oracle 11gR2.
I want to install RAC using two or more servers but I dont know too much about it.
I tried to search on google but all they are giving information in pieces(for win 7) or about Linux(Please tell me why its all Linux everywhere not windows).
Please let me know if there any site where I can find step by step installation from scratch.
What are basic requirements(/software if needed).
Thank you.

Hi,
First of all forget about Windows!! Oracle is mainly designed for Linux systems. Oracle runs as real multi-process on Linux machines whereas on Windows it runs as a single process with multi-thread.
Memory usage - huge pages,single CPU run queue, dnfs, storage systems... etc. lots of concepts exists.
Besides Windows is one of the most poorly designed operating systems, you should use it only to watch cute kitten movies on youtube... Believe me, you wouldn't want to learn Oracle on Windows...
So, install virtualbox and then setup Oracle Enterprise Linux on it as a first step... By the way you have to deal with DNS server for release 11.X, RAC, you may start with 10g for now.
ORACLE-BASE has all the installation steps explained detailly, search for "oracle base rac install" on google.
I also explained on my blog, but it is a little bit advanced installation using ZFS storage simulator. DNS server installation is also explained: http://ilkertaysi.com/2013/11/11/oracle-rac-installation-with-zfs-storage/

Re: How to install Oracle RAC using 11gR2 on Win 7 32 bit from scratch?

Hi,
I'd suggest to use the Virtual box(Free download from Oracle) and use the steps mentioned in the link.. for RAC Setup for your practice
http://www.oracle-base.com/articles/11g/oracle-db-11gr2-rac-installation-on-oel5-using-virtualbox.php
HTH

Thank you DK2010,
Your answer was very helpful to me but please tell me why everybody suggest about virtual box? Is is very important? and what is the benefit?
And I was checking that testing that branch option thats why this post become branch of my discussion.

How to convert single instance10g db to 11gR2 RAC with ASM

Hi,
I need your help to decide the plan about how to convert single instance 10g database to 11gr2 rac with asm.
I can have about 6 to 8 hours of downtime to upgrade and move to rac with asm.
db size is about 1.5tb and on AIX.
here is my plan....
1) install 11gr2 rac with asm on two nodes
2) verify rac installation and clustered asm
3)install 10g oracle binaries( yes 10g )
4) shutdown production db ( machine prod )
5) make copy of production and restore on 1st node ( using shadow image , so it's quick and its file system )
6) upgrade db to 11g ( still of file system )
7) after successful upgrade, move to asm ( rman backup )
8) add another node
does it look okay ? OR is there a better approach to save time?
can someone help me ?
Thanks...

Thanks ...
So here is what I thought... suggest if something is not right...
1) install 11gr2 grid infra on node A and B with ASM
2) stop CLUSTER ON BOTH NODES.
3) shutdown prod db on 10g ( downtime starts )
4) take rman cold backup
5) restore rman backup on node A on ASM ( as if single instance 11g , no rac parameters )
6) mount and run upgrade script for 11g, then open db with 11
7) after successful upgrade, shutdown db node A
8) change all rac related parameters, spfile,undo,redo for rac environment on both nodes
9) open db in rac environment
can I do this way ?
My only question is, even though I installed rac on node A and B, in step 5 and 6 I'm using only node A as if it is single instance. Is it possible ?
if it is then I'm good to go...
Thanks for all suggestions.

11gR2 Grid Infrastructure and 11gR2 RAC install as separate users (RH 5)

We are about to set up a few new RH 5 clusters and are trying to make a decision if we should install 11gR2 Grid Infrastructure and 11gR2 RAC as the same user (oracle) or as separate users (grid and oracle) as per Oracle documentation.
I would like to know what other people are doing and their experiences with this.
Here are some concerns that we have:
1) Does Oracle support has an 11gR2 cluster environment where grid infrastructure and oracle database are installed as separate users ? I have been to a few Oracle 11gR2 demos and they always have a simple install where everything is installed as a single user.
2) Potential permission issues that we might hit iif we use separate users, for example
- grid control agent - which user do we install it as and will it be able to access both grid and oracle files ?
- database listener will run as grid user. Is this going to cause any permission issues ?
Thanks in advance for your answers

It is all dependent on your business whether your business needs to separate between privileged user for storage administrator (ASM) or database level. It is recommended to have user separation but not mandatory.
see http://download.oracle.com/docs/cd/E11882_01/install.112/e17212/toc.htm for the details
permission issues might happen if the configuration is not correct. for example you might see ORA-12537 when configuring the system
Hope this helps

Cannot Startup Grid in 11gR2 RAC after Install Grid Successfully

Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 VMs (main VM rac1 and slave VM rac2) with Oracle Linux 5.6 according to the website http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
Grid and RAC database have been installed successfully for both VMs rac1 and rac2.
I am using the slave VM rac2 to test Grid and RAC database because rac1 disk is full.
The problem is that OCR file is not available or currupted in the slave VM rac2.
I have created a pfile and add entry in the file sqlnet.ora in the slave VM rac2. By now, I still cannot startup Grid as below:
[ora11g@rac2 /]$ cd u01/app/grid/bin/

I have checked that there is no the file init+ASM2.ora in the directory '/u02/11g_db/ora11g/dbs'.
As we see the outputs above, my question is:

Thanks.

Folks,
Hello. Thanks a lot for replying. Let's analyze 3 cases as follows:

Case 3:
Now, as you indicated, I export ORACLE_SID=racdb2, the output is below:
[ora11g@rac2 bin]$ pwd

As we see the ouputs above, export ORACLE_SID=racdb2 doesn't have any effect. My question is:
Can any folk help to solve the above 3 issues to start up Grid ?
Thanks.

Can you use 11gR2 database for 11gR1 standalone?

Do to the fact that Oracle has not released 11gR2 standalone on windows, our users want us to install the 11gR1 OWB components
I would like to keep the database version 11gR2, so installed the standalone 11gR1 on the server.
When I try to create the workspace I get the following error
Process element SeedData.xml 99%
(X)
The warehouse builder workspace owner installation failed on user OWBSYS
INS0017: Installation of the seeded data failed.MMM1064: Value 11.2 not valid in domain VERSION2
So can we install the 11gR1 repository in the 11gR2 database? Having lots of trouble finding the certification info in the new metalink

..the OWB 11gR1 and 10gR2 versions are not certified with database 11gR2 today.
Cheers

Hi,
One of the recommended solution for this issue by Oracle.
Have the DISPLAY variable set when running root.sh. This is the th recommendation by oracle to a SR opened by another vendor for this issue.

Install 11gr2 grid question

Hi I will be installing 11gr2 on rhel6 and have a question.
Since I need to install the gird infrastructure for before the rdbms and the grid infrastructure will be installed using the user grid as opposed to the oracle user id I am wanting to know if I need to configured multiple Oracle_base directories?
I usually would just create /u01/app/oracle and set that as the oracle_base. Can I use that for grid(infrastructure) and oracle (rdbms) for both installations. I have read the install guides and unfortunately it is still unclear to me. I am planning to install rac database.
Thanks for any hekp it is greatly appreciated.

In 11gr2, Grid infrastructure software contains both clusterware and ASM.
Prior to 11g, we used to have 3 ORACLE_HOMES one for cluster, ASM and rdbms.
For eg:
In 11g r2, Your RAC binaries set up could be like this:
Grid Infrastructure Software (Clusterware + ASM 11.2.0.1):
Server: on all RAC nodes
ORACLE_BASE: /u01/app/grid
ORACLE_HOME: /u01/app/grid112
Owner: grid (Primary Group: oinstall, Secondary Group: asmadmin, asmdba)
Oracle Database Software (RAC 11.2.0.1):
Server: on all RAC nodes
ORACLE_BASE: /u01/app/oracle
ORACLE_HOME: /u01/app/oracle/db112
Owner: oracle (Primary Group: oinstall, Secondary Group: dba)

How to install oracle 11gR2 Grid Infrastructure for standalond server

Hi Experts,
we do not want to install ASM. under this condition, does any expert install oracle 11gR2 Grid Infrastructure for standalone server in Linux 5 at file system?
Please share tip and experiences of installed oracle 11gR2 as single instance include install oracle 11gR2 Grid Infrastructure for standalone server in Linux 5. no one node RAC configuration.
If we do not install 11gR2 Grid Infrastructure for standalone server . which function will be lost? restat server only?
Thanks
Jim

Grid Infrastructure automatically uses Oracle Restart as default if you're installing Standalone. You can turn this off using crsctl ('disable has', I believe).
According to the inference in the install docs (http://download.oracle.com/docs/cd/E11882_01/install.112/e16763/oraclerestart.htm#CIHCBGCC), you can install 11gR2 without Grid Infrastructure, but you lose ASM and Restart.
