Hi,
GPFS is not free, and needs to be purchased.
ONLY GPFS 2.3 is certified with RAC as for today.
Certification for 3.1 ion under way.
About 9iRAC and HACMP on AIX 5.3, ONLY HACMP 5.1,5.2 and 5.3 are supported, not yet HACMP 5.4. For info, 10gRAC is only supported with HACMP 5.1 and 5.2.
To find out how to setup HACMP for a 9iRAC installation, you can use the following document, available on http://www.oracleracsig.org :
CookBook V3.2 - Oracle 9iRAC on IBM@server pSeries running AIX5L
(Step-by-step installation guide for 9iRAC on AIX5L. Whith HACMP for database on concurrent raw devices And IBM GPFS for database on shared cluster filesystem. Including HACMP and GPFS setup.
The document covers HACMP 5.1 or 5.2, not 5.3 release, but it should be nearly the same with some screen changes.
Point which is different with the cookbook for now, it's the way to create the lv (logical volume), you should use the "-T O" options for it.
Hope it will help.
Regards.
Fred.

We're running CRS on AIX. No ASM or HACMP.
We do have the db datafiles on GPFS. We've also got one voting disk on GPFS and two on raw devices.

RAC on AIX 6.1 with HACMP

Hi
Can I have installation procedure and documents to Install 10gR2 RAC on AIX 6.1 using HACMP(for cluster control) instead of Oracle Clusterware. Is that possible ? anyone tried it before and share the experience.
Regards,
Akthar

Do you have any particular reason for using HACMP cluster control instead of CRS?
As you are going to install 10GR2 RAC So there is no need to use HACMP because 10G CRS can be installed without OS clusterware.
However CRS can be installed along with HACMP but oracle services should be controlled with CRS inly.
Regards
Rajesh

Oracle 10g RAC 2节点不定期重启

Oracle 10g RAC 2节点不定期重启
oracle数据库版本10.2.0.5，两个节点的RAC， AIX 6.1 + PowerHA 5.5
近期2节点操作系统不定期重启，表象是心跳网络出了问题，但查找不到具体原因，
但我发现了一个奇怪的问题
$ crsctl get css misscount

按Oracle的说法，使用第三方的集群软件，misscount为600s，
请教大家，crs的这个misscount，启动的时候，是在哪儿读取的？为什么会出现值不一致呢？

Oracle 10.2 on AIX 6.1

Hi all,
I have to install oracle 10.2 on AIX 6.1 , first I installed 10.2.0.1 and after I upgraded it to 10.2.0.3.
I forgot to run the patch 6613550 before installing (10.2.0.1) and upgrading to 10.2.0.3.
Should I recommence the installation from scratch OR can install it after upgrading to 10.2.0.3 ??
thanks in advance.
S. Hage

For installation on AIX it is mandatory that you run rootpre.sh before you commence installation. As you have not run it i suggest you to reinstall. The below are set when you run rootpre.sh and it is required for Oracle.
1. Async IO has to be configured.
2. Post/Wait Kernel extension should be installed.
3. Kernel Statistics extension should be installed
Do you happen to have a higher version of Oracle i.e. 11g installed on this server? If you will not have to run rootpre.sh

Oracle 9i rac interconnect

Hai,
I need clarification in oracle 9i rac internetconnect. Recently we have done installation of oracle 9i rac (9.2.0.4) on aix 5.3 with hacmp cluster for 2 nodes. We are not able to mount the second instance of the database after starting the first instance.
The problem was solved after adding cluster_interconnect parameter in the init.ora file. In all other servers, it is not given and oracle is selecting the interconnect automatically. For this new server alone this problem. I want to know from whether oracle is taking this interconnect if we dont mention the cluster_interconnect paramter. Even i have verified /etc/hosts file and entries are available in it. Requeting your help in this regard.

Where the IP information is stored and managed from depends on your implementation such as are you using a third party clusterware. If you are using Oracle clusterware its stored in the OCR.
You can check this using the following query...
SELECT * FROM GV$CLUSTER_INTERCONNECTS;
The source column will tell you where the interconnect information was obtained from.
BTW, if you are using the CLUSTER_INTERCONNECTS parameter you may loose some of the HA features here is something from the 10gR2 documentation..
" Failover and Failback and CLUSTER_INTERCONNECTS
Some operating systems support run-time failover and failback. However, if you use the CLUSTER_INTERCONNECTS initialization parameter, then failover and failback are disabled."
Question, have you tried other options such as NIC pairing and bonding to have dual interconnects instead of using the CLUSTER_INTERCONNECTS parameter.
Please check Metalink Note # 298891.1 talks about configuring NIC bonding on Linux there are similar options for other operating systems.
answered by Murali Vallath refer the link: this will be very useful to you.http://kr.forums.oracle.com/forums/thread.jspa?threadID=625931
hope, this will helps you.

Thanks
Saiprasath

If by "advantages of installation of oracle 10g rac on open solaris on x86 machine" you mean advantages over RAC on Linux or AIX or HP/UX there aren't any.
If you want to know the advantages of RAC over stand-alone they generally relate to:
1. Eliminating the server as a single point of failure
2. Transparent fail-over
2. Incremental horizontal scalability

Install oracle 9i rac access from both node problem

Hai,
Recently we have planned to move oracle 9i rac databases to new servers. Our current configuration is oracle 9i rac (9.2.0.4) and aix 5.3 with hacmp 5.4
mksysb backup has been taken from old machine and restored in the new machine. For oracle binarys, tar have been done and restored in the new machine.
Now after restoring the database, i am able to mount and open from the one server at a time. If i try to mount the database from second machine it is hanging. Kindly help us to solve the problem.

10g R2 RAC in AIX

Hello,
I always work with Linux (red hat) to build our RAC clusters, and I never have seen "abnormal" performance and stability issues.
Well, now I'm in a project to build a RAC in AIX 5.3. Somebody please can share the experience on this plataform? What is the "best practice" use or not HACMP? I've search in metalink and there's a lot of bugs related to Clusterware in AIX, the system is stable with RAC?
Thanks.

Hi user572788,
HACMP is optional option for RAC on AIX, start with 10g, Oracle Clusterware doesn't depends on vendor cluster. I have a RAC 10g on AIX running with HACMP too, as long as you configured correctly and in certification matrix, you shouldn't see any problems. For me RAC on AIX is quite stable but still has a small issues. No system is perfect in this world
Cheers

RAC Newbie: Does RAC on AIX require HACMP?

I've never installed/configured RAC before, and the documentation I'm finding has conflicts on whether HACMP needs to be installed. One FAQ states the following:
Is HACMP needed for RAC on AIX 5.2 using GPFS file system?
The newest version of GPFS can be used without HACMP, if it is available for AIX 5.2 then you do not need HACMP
Another documentation article states HACMP is REQUIRED for 9i RAC on AIX.
Does anyone know the real answer to this question? Our configuration is AIX 5.3, GPFS 2.1, Oracle 9.2.0.4. Thanks in advance!!

The latest information from Oracle says:
Oracle9i RAC always requires HACMP.
HACMP is optional for Oracle Database 10g RAC.
See details in metalink note
IBM General Parallel File System (GPFS) and Oracle RAC on AIX 5L and IBM eServer pSeries
