RAC Install

We are in the process of RAC install. The Oracle requirements state that a crossover cable cannot be used for the private network. The requirement states that each server must be cabled through a switch (1GB port each) and then separated on a private VLAN. It creates actually 2 more points of failure and I am curious as to why it is necessary?
Does anyone have a technical explanation, other than Oracle requires it?

1GB switch requirement is to have a stable and fast network connection for the cluster interconnect.
The interconnect will be used to all the critical messages and heart beats packets between the nodes. So any delay or drop of packets int he interconnect could cause performance issues or node evictions in the cluster.
You can go for redundancy at the hardware level to avoid a single point of failure.
Thx,Jomon

RAC Instalation Problem (shared accross all the nodes in the cluster)

All experts
I am trying for installing Oracle 10.2.0 RAC on Redhat 4.7
reff : http://www.oracle-base.com/articles/10g/OracleDB10gR2RACInstallationOnLinux
All steps successfully completed on all nodes (rac1,rac2) every thing is okey for each node
on single node rac instalation successfull.
when i try to install on two nodes
on specify Oracle Cluster Registry (OCR) location showing error
the location /nfsmounta/crs.configuration is not shared accross all the nodes in the cluster. Specify a shared raw partation or cluster file system file that is visible by the same name on all nodes of the cluster.
I create shared disks on all nodes as:
1 First we need to set up some NFS shares. Create shared disks on NAS or a third server if you have one available. Otherwise create the following directories on the RAC1 node.
mkdir /nfssharea
mkdir /nfsshareb
2. Add the following lines to the /etc/exports file. (edit /etc/exports)
/nfssharea *(rw,sync,no_wdelay,insecure_locks,no_root_squash)
/nfsshareb *(rw,sync,no_wdelay,insecure_locks,no_root_squash)
3. Run the following command to export the NFS shares.
chkconfig nfs on
service nfs restart
4. On both RAC1 and RAC2 create some mount points to mount the NFS shares to.
mkdir /nfsmounta
mkdir /nfsmountb
5. Add the following lines to the "/etc/fstab" file. The mount options are suggestions from Kevin Closson.
nas:/nfssharea /nfsmounta nfs rw,bg,hard,nointr,tcp,vers=3,timeo=300,rsize=32768,wsize=32768,actimeo=0 0 0
nas:/nfsshareb /nfsmountb nfs rw,bg,hard,nointr,tcp,vers=3,timeo=300,rsize=32768,wsize=32768,actimeo=0 0 0
6. Mount the NFS shares on both servers.
mount /mount1
mount /mount2
7. Create the shared CRS Configuration and Voting Disk files.
touch /nfsmounta/crs.configuration
touch /nfsmountb/voting.disk
Please guide me what is wrong

I think you did not really mount it on the second server. what is the output of 'ls /nfsmounta'.
step 6 should be 'mount /nfsmounta', not 'mount 1'. I also don't know if simply creating a zero-size file is sufficient for ocr (i have always used raw devices, not nfs for this)

Need 11gr2 RAC install Guide on Solaris 10 x86 using containers and NFS

I'm looking for an 11gr2 RAC install Guide on Solaris 10 x86 using 2-3 containers. I need to have the NFS server reside in the global zone or on a 3rd container visable to the two rac containers.
Please share me installation guide!
Thank you!
PS - I currently have run into an install issue -
Can't change ownership on /oracle/products/11.2.0/ocr/: not owner at /oracle/app/11.2.0/grid/crs/install/crsconfig_lib.pm line 5014.
I suspect the NFS share params from the NFS server in the global zone are not 100% correct to the two rac zones/containers.

Have you visited Oracle Support Services website (formerly metalink) to determine if your desired configuration is supported?
Last time I looked it was not.
That said Oracle database installation guides are fully documented online.

Clone RAC Install - CRS and RDBMS Homes

Hi All,
I have used the clone option with oui to clone an existing Oracle RDBMS home as per Metalink article 300062.1.
I am interested in cloning a RAC install , including CRS nd RDBMS homes , and can see that the clone directory exists , so assume it must be possible, does anyone know if there are specfic instructions on how to clone a CRS/RAC install ?
Thanks,
Darrell

What does choosing interface as public or private during rac install mean?

What does choosing interface as public or private during rac install mean? You see the option on the OUI screen in the step after adding nodes on which you need the install.

Public: Is the interfacce where the connection to the db is done (user, application server etc).
Private: Used for communication between the nodes in the cluster and is done by the instances. No one should be able to connect via this interface.

11gR2 RAC Install Doc on HP-UX

Hi ,
My client is planning to go for 11gR2 on RAC ASM.I know the normal steps how we will follow for RAC install on Linux.
In the case of HP-UX , It does need some packages before going for install.
Please guide me the steps and procedure how we will follow the 11gR2 RAC on HP-UX.
Sharing any real time or oracle doc is helpful to me.
Thanks & Regards,
Sunand

I raised the same thread under Grid->Install
Thanks to all

Please verify my RAC install with ASM procedure with a question.

Good morning.
My installation procedure on RAC with ASM (ASM will be on separate home from DB):
1. Install clusterware 10.2.0.1
2. Apply database patchset 6810189 upgrade clusterware to 10.2.0.4
3. Apply CRS patch bundle #4 8436582 to clusterware
4. Install oracle DB home 10.2.0.1
5. Apply database patchset 6810189 upgrade to 10.2.0.4
6. Apply DB PSU (patch# 8576156) 10.2.0.4.1 (includes CPUJUL2009) to the oracle home
(steps 7-9 are similar as step 4-5, except for ASM home. Or should I install ASM home before installing DB home? )
7. Install oracle DB home 10.2.0.1 for ASM and configure ASM
8. Apply database patchset 6810189 upgrade to 10.2.0.4 for ASM
9. Apply DB PSU (patch# 8576156) 10.2.0.4.1 (includes CPUJUL2009) to the oracle home for ASM
10. Run DBCA to create database.
Can I apply DB PSU (patch# 8576156) 10.2.0.4.1 (INCLUDES CPUJUL2009) to DB while the clusterware is 10.2.0.4, as I know DB version should not be higher than clusterware version? Or can I upgrade clusterware to 10.2.0.4.1?
Thanks for advice,

Hi,
Applying PSU (10.2.0.4.1) does not mean that you are moving to higher version of Oracle. Oracle releases will be like 10.2.0.4 , 10.2.0.5 like that.
10.2.0.4.1 is the PSU version for Jul 2009 PSU.
10.2.0.4.2 is the PSU version for Oct 2009 PST.
Like CPUs PSUs are also quarterly. It is not necessary oracle should release the PSU/CPU for every oracle home/CRS home every quarter.
For now, the PSU (Patch no: 8576156) is only applicable as shown below.
PSU 10.2.0.4.1 includes the following previously released bundle patches:
- Generic Recommended Bundle #4 (Patch 8362683)
- RAC Recommended Bundle #3 (Patch 8344348)
- Data Guard Broker Recommended Bundle #1 (Patch 7936793)
- Data Guard Physical/Recovery Recommended Bundle #1 (Patch 7936993)
- Data Guard Logical Recommended Bundle #1 (Patch 7937113)
Refer to the installation types of this patch (download README of this patch bundle).
Table 1 Installation Types and Security Content
Server homes - PSU 10.2.0.4.1
Client-Only Installations - None
Instant Client Installations - None
(The Instant Client installation is not the same as the client-only Installation.
For additional information about Instant Client installations, see Oracle Database Concepts.)
ASM (Automatic Storage - PSU 10.2.0.4.1
Management) homes
CRS (Cluster Ready Services) - None
homes
So, there is no PSU patch for this quarter for CRS Home. You may check the previous CPU/PSUs to make your home secured/updated with all patches.
Regards,
Vasu

In the first place a 'blue screen' has to be analyzed on the OS side, Oracle COULD be the reason, but who knows? More likely a hardware problem (RAM,disk storage). So you have to ask your system administrator and/or call Microsoft support. Or you try to find an answer in one of the many articles in the web, for example this:

Oracle10G RAC install on Solaris 10

Please suggest some good and simple install document for Oracle 10G RAC on Solaris 10 Sparc?

In my opinion I would not use physical shared storage at all.
Get VMWare Server, a suitable OS and a big hard disk and one PC with lots of RAM.
Use this to create your RAC environment. It works perfectly and is much easier than using multiple devices which require multiple network cards and suitable storage.
I have a Dual Core PC running XP with 2GB RAM. You can get RAC working with 2 VM's each allocated 512MB which will do for learning purposes. This also has an advantage I can take it with me when I am away from home.

Oracle Database 10g - RAC install

1)
I am trying to install Oracle 10g RAC (for Solaris Operating System (SPARC)) using 'Enterprise/Standard Edition for Solaris Operating System (SPARC, 64-bit) - ship_rel10_sol64_db.cpio.gz' downloaded installation. There is no separate installation for RAC, so I assume this is the right install to use for RAC, right?
Since I don't have cabeling for Interconnect done yet, I tried to install Database/RAC prior CRS installation, but no option has been offered for RAC. Do I need to have clustering software installed first in order to be able to installl Oracle Database RAC?
2)
Why is Oracle Database 10g release 10.1.0.3 patch set (for Solaris Operating System (SPARC)) so large - 648 MB?
Do I need to install 10.1.0.2 first?

Hello,
there's no extra RAC software package, but the option is only offered, if one of the supported cluster layers for the respective OS has been installed before.
10.1.0.3 looks like a complete redesign, but anyway it is a patch, you have to install 10.1.0.2 first.

11g RAC install on virtual box hangs

Host - windows 7 64bit
guest - Oracle Enterprise linux 5.2 32bit
Virtualbox 3.2.6
Hi all,
I really need some help. I'm trying to install 11gr1 rac on Oracle Enterprise linux 5.2 32bit with nfs. The crs install goes fine, but when I want to install the database software, it just hangs, sometimes at 2%, sometimes at 45%. I can't open another terminal window or nothing, but the tick still goes black and white.
I'm using the following doc, and followed it exactly.I gave both nodes 1280 ram, 30 gig disk size, to grow as it's being used.
Any help will be welcome, I have been sitting with this issue for a month now, and have tried reinstalling from the os level numerus times.

Hi,
as far as I remember VirtualBox 3.2.6 does not support shared disks, therefore it's not possibe to set up RAC on it.
3.2.8 supports shared disks, and there's also information available on how to set RUC up on it: [http://www.oracle-base.com/articles/11g/OracleDB11gR2RACInstallationOnOEL5UsingVirtualBox.php]

RAC Install fails with "OCR upgrade failed with (-1073741819) on 10.2.0

I am trying to install RAC 10.2.0 with two Server 2003 R2 nodes connected to a fiber channel SAN. I have set up the shared storage, created the extended partitions, and setup the unformatted no drive letter volumes. Both servers see the unformatted volumes (and no others do). The preinstallation checks work fine and the installations works fine until the first configuration assistant runs. That would be the "Oracle Clusterware Configuration Assistant". It tries to run crssetup.config.bat and fails on step 3 (configuring OCR Repository) with
ocr upgrade failed with (-1073741819)
If I uninstall clusterware and try again it will not show the OCR and Voting disks as available disks until I delete the volumes and partitions and recreate them. I have run the precheck batch files and they show everything as good as well. When I define the OCR and Voting drives in the clusterware setup I do not select format or assign drive letter. Every time I try to do the install I get the exact same error.
Is there anything I am missing or some trick or patch I may not have done?

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

Permission Denied error on RAC Install Sun SPARC Solaris-NetApps

Our RAC Installation is failing when installing in silent mode the base install of Oracle RDBMS 10.2.0.1. During the process file emtgtctl is copied from node1 to node2. On node1 the file has the following permissions:
-rwsr-s--x (note the user group and set-id "s" is on).
Oracle user is performing the intsall and he is a member of oinstall.
We get the error:
"Permission Denied" and the install fails.
We try and do the copy manually as well and this fails also.
Any one ever run accross something like this?

is oinstall the primary group for that user ?
