Veritas Cluster 6 + Solaris 11 + Oracle RAC 11g2 = OCR trouble

I trying new version of Veritas Cluster and Solaris.
Experienced trouble with clustered VxFS for OCR file.
Grid installer refuse VxFS with message - not support the storage type.
After installation I tryed to add new OCR file on VxFS got message in crsd.log:

What can be the reason for this error?

Trouble was solved by VCS patch 6.0.3
Version 6.0.1 does not support Solaris 11.1

Encountered ora-29701 during Sun Cluster for Oracle RAC 9.2.0.7 startup (UR

Hi all,
Need some help from all out there
In our Sun Cluster 3.1 Data Service for Oracle RAC 9.2.0.7 (Solaris 9) configuration, my team had encountered
ora-29701 *Unable to connect to Cluster Manager*
during the startup of the Oracle RAC database instances on the Oracle RAC Server resources.
We tried the attached workaround by Oracle. This workaround works well for the 1^st time but it doesnt work anymore when the server is rebooted.
Kindly help me to check whether anyone encounter the same problem as the above and able to resolve. Thanks.

Problem statement:
ORA-29701 DURING DATABASE CREATION AFTER APPLYING 9.2.0.6 PATCHSET
*** 03/25/05 07:32 am ***
TAR:
PROBLEM:
Customer applied 9.2.0.6 patchset over 9.2.0.4 patchset.
While creating the database, customer receives following error:
ORA-29701: unable to connect to Cluster Manager
However, if customer goes from 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the problem does not occur.
DIAGNOSTIC ANALYSIS:
It seems that the problem is with libskgxn9.so shared library.
For 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the install log shows the following:
installActions2005-03-22_03-44-42PM.log:,

For 9.2.0.4 -> 9.2.0.6, install log shows:
installActions2005-03-22_04-13-03PM.log:, [libcmdll.so ->%ORACLE_HOME%/lib/libskgxn9.so 64274 plats=1=>[46] langs=-554696704=>[en]] does not exist.
This means that while patching from 9.2.0.4 -> 9.2.0.5, Installer copies the libcmdll.so library into libskgxn9.so, while patching from 9.2.0.4 -> 9.2.0.6 does not.
ORACM is located in /app/oracle/ORACM which is different than ORACLE_HOME in customer's environment.
WORKAROUND:
Customer is using the following workaround:
cd $ORACLE_HOME/rdbms/lib make -f ins_rdbms.mk rac_on ioracle ipc_udp

Sun cluster and oracle RAC

my client is insisting on putting oracle RAC on top of sun cluster, the thing is i don't know what is the benifit of creating such an architecture, i tries to search on the internet but couldn't understand the benifits nor the advantage, Kindly if some one has implemented such an architecture to let us know the use and the benifits

Hi,
Here on my environment, there is SUNCluster only for single instances. The Clusterware Oracle is complete providing high availability and load balance for your database, you don't need sun cluster with this case, no advantages gained. The only thing controlled by SUNCluster on my RAC environment is QFS (Cluster file system from SUN).
If search on this forum, there are many discussion by this topic (suncluster X RAC) like this post Re: Sun Cluster.. Why?

Where to download Oracle RAC 11g2 CRS/clusterware?

Hello experts.
I'm building a home/test Oracle RAC environment on 11g2 and I can't seem to find the CRS/Clusterware for download?
I've been able to download the CVU and verify all of the server/OS/systems configuration work that was needed upfront.
I'm running on CentOS 5.5 (RHEL 5.5), on a Sun Sunfire v20z, that has FC disk array and FC HBA's connected over fiber (LC/LC connections).
I've downloaded the Oracle 11g2 software 1&2, and also the Grid software, and the CVU software.
CVU shows all configurations passed... can anyone point me in the right direction? I'm assuming Oracle allows people to download CRS/Clusterware for non-commercial (personal education) purposes without license?
Please advise.
Thank you.

Hi,

I'm assuming Oracle allows people to download CRS/Clusterware for non-commercial (personal education) purposes without license?Oracle Clusterware and Oracle ASM binaries are installed as a single binary called the grid infrastructure. So, If you downloaded Grid Infrastructure you already have the CRS and ASM installation.
All software downloads are free, and most come with a Developer License that allows you to use full versions of the products at no charge while developing and prototyping your applications, or for strictly self-educational purposes.

Veritas required for Oracle RAC on Sun Cluster v3?

Hi,
We are planning a 2 node Oracle 9i RAC cluster on Sun Cluster 3.
Can you please explain these 2 questions?
1)
If we have a hardware disk array RAID controller with LUNs etc, then why do we need to have Veritas Volume Manager (VxVM) if all the LUNS are configured at a hardware level?
2)
Do we need to have VxFS? All our Oracle database files will be on raw partitions.
Thanks,
Steve

> We are planning a 2 node Oracle 9i RAC cluster on Sun
Cluster 3.Good. This is a popular configuration.
Can you please explain these 2 questions?
1)
If we have a hardware disk array RAID controller with
LUNs etc, then why do we need to have Veritas Volume
Manager (VxVM) if all the LUNS are configured at a
hardware level?VxVM is not required to run RAC. VxVM has an option (separately
licensable) which is specifically designed for OPS/RAC. But if
you have a highly reliable, multi-pathed, hardware RAID platform,
you are not required to have VxVM.
2)
Do we need to have VxFS? All our Oracle database
files will be on raw partitions.No.
IMHO, simplify is a good philosophy. Adding more software
and layers into a highly available design will tend to reduce
the availability. So, if you are going for maximum availabiliity,
you will want to avoid over-complicating the design. KISS.
In the case of RAC, or Oracle in general, many people do use
raw and Oracle has the ability to manage data in raw devices
pretty well. Oracle 10g further improves along these lines.
A tenet in the design of highly available systems is to keep
the data management as close to the application as possible.
Oracle, and especially 10g, are following this tenet. The only
danger here is that they could try to get too clever, and end up
following policies which are suboptimal as the underlying
technologies change. But even in this case, the policy is
coming from the application rather than the supporting platform.

Oracle RAC on solaris Cluster - advantages

Hi,
I wonder what are the advantages of installing Oracle Rac on solaris Cluster.
Oracle Rac is a cluster solution by itself and puting it to solaris Cluster will complicate a whole system a lot.
One advantage I know iis that solaris cluster will secure a voting disks but those could be also secure by using NFS.
Please give me your opinion if its worth in general to iinstall RAC 11g in solaris cluster 3.2.
How do you think, will Oracle extend the solaris cluster solution for databases in the future ?
Many thanks in advance.

CRS is built to manage RAC. Using any other cluster software for RAC will complicate the solution without adding benefit.
But if you are building a cluster to run application servers etc, then it would be better to use a more flexible cluster solution. (e.g NOT crs)

Oracle RAC one node

why Oracle introduced Oracle RAC one node in 11gR2?
I have gone through oracle documents on oracle rac one node, but i couldn't find much added advantage than instance failover. We have already some technologies like datagaurd and some third party softwares for instance failover.
Then why oracle introduced this RAC one node in the new release i.e 11gR2?
What exactly oracle wants to provide from oracle RAC one node?
Thanks...
Bharath

Why RAC one node?
Oracle RAC one node is a single instance of Oracle RAC that runs on the node in a cluster. The benefit of the RAC one node option is that it allows you to consolidate many databases into one cluster without a lot of overhead, while also providing high availbilty benefits of failover protection, as well as for Online rolling patch application and rolling upgrades for the Oracle clusterware.
Another aspect of RAC one node allows you to limit th CPU utilization of individual database instances within the cluster through a feature called resource manager instance caging, which gives you the ability to dynamilcally change the limit as required.
Furhtermore , with RAC one node there is no limitation for server scalabilty such that if applications outgrow the current resources than a single node can supply, you can then upgrade the applications online to Oracle RAC.
In tthe event that the node which is runnig Oracle RAc one node becomes saturated and out of resources, you can migrate the instance to another node in the cluster using Oracle rac one node and another new utilty called OMOTION feature.OMOTION feature for Oracle RAC 11g R2 rac allows you to migrate a running instance to another server without downtime or distrubtion in service for your enviornment.
Hope you're understand.

Domain migration of Oracle RAC nodes on windows 2008

Hello masters,
We are planning to migrate servers from old domain to a new domain due to company name change. That is, our DB servers named like db-node-x.old-domain.com will be migrated to db-node-x.new-domain.com. The servers are all on Windows 2008 R2 and Oracle RAC 11g2. As dba, i have no idea about what will happen to DBs. Please let me know any possible solutions?
Thanks in advance.

which documentation you have followed?

Changing oracle_home(standalone to ORACLE RAC).

Customer has two oracle environments on the same envioronments.
1) Standalone database running on Standalone oracle_home.
2) RAC databases running on RAC ORACLE_HOME.
Now customer would like to change standalone database to RAC ORACLE_HOME. What is the procedure for this.
Oracle version is 11.2.0.3.4 on both environments. Just i need to change the oracle_home only. If any additional clarifications...happy to reply with more details....
Thanks in-advance.

Please use the below link, its helpful
http://docs.oracle.com/database/121/RACAD/cvt2rac.htm
Single-Instance Database on a Cluster Running from an Oracle RAC-Disabled Home
You can create a single-instance database on a cluster running from an Oracle home with the Oracle RAC option disabled. To create an Oracle home on a cluster with Oracle RAC disabled, you can select local and non-cluster on the Node Selection Page of Oracle Universal Installer when installing the Oracle Database software. You can also performed a one-node cluster (with Oracle RAC) installation, but later disable the Oracle RAC option.
Perform the following procedures to convert this type of single-instance database to an Oracle RAC or Oracle RAC One Node database:
1.    Use DBCA to create a preconfigured image of your single-instance database as described in "Use DBCA to Create an Image of the Single-Instance Database" To perform the conversion manually, shut down the single-instance database.
2.    Change the directory to the lib subdirectory in the rdbms directory under the Oracle home.
3.    Relink the oracle binary by running the following commands:
4. make -f ins_rdbms.mk rac_on
5. make -f ins_rdbms.mk ioracle

VIP failover in Oracle RAC

Dear all,
I am using Oracle Rac 10gR2 running on top of Sun Cluster 3.2u3.
I have a test to check the failover ability of VIP in Oracle RAC, however the result was not as I expected.
The test scenario was:
- Turn on the 02 nodes and wait for all services including both Sun Cluster and Oracle RAC online.
- Using SQL Navigator to connect to the database using the VIP on node1. (VIP1)
- Shutdown the node1.
- All services and resources on node2 still online, however after a long time (about 10 mins), I did not see the VIP1 failover to the alive node.
- The "crs_stat -t" command did not show the VIP1 online on node2 (alice node).
- The SQL Navigator could not establish the connection to the databasse using the VIP1 any more.
The output of "crs_stat -t" command before shutting down the node1:
oracle@t5120-02 $ crs_stat -t
Name Type Target State Host
ora.orcl.db application ONLINE ONLINE t5120-02

So my questions are:
- Was my test scenario correct to check the failover ability of VIP in Oracle RAC?
- Is there any additional configuration needed to perform on the system to achieve the VIP failover?
Please help me in this case as I am new to Oracle RAC.
Thanks.
HuyNQ.

Dear Rajesh,
Sorry for late reply.
I have already tested 02 cases: shutting down a node and crashing a node. Below are the output of the log files in the 2 test cases.
Once again, when shutting down a node, the VIP did not failover although the CRS on that node was shutdown before all other services and resources of Sun Cluster shutdown.
Please help to check the log files and give me advise if you see anything abnormally.
Thanks.

Is Veritas- or Sun Cluster needed for RAC in a Solaris Environment

Is a Veritas- or Sun Cluster needed for RAC in a Solaris Environment?
Does anyone know, when OCFS will be available for Solaris?

You don't need Veritas Cluster File System, but until OCFS comes out for Solaris you need to think about backups. If you've not got a backup solution that can integrate with rman for an SBT device then backups become more tricky.
If you use ASM then you can take a backup to a "cluster filesystem" (although ASM is raw partitions think of it as a cluster filesystem), that both nodes can see. BUT you then need to get these to tape somehow, unless you've got NetBackup et al. that support RMAN and can backup direct to tape you're more stuck.
Too many people don't think about this. You could create an NFS mount and backup to this from the nodes.

2=> Sun Cluster 3.1
3=> Veritas Volume Manager
4=> Veritas Cluster File System
Can i deploy Oracle RAC using the above listed Software.
Here we have not purchase any of the Cluster Volume Manager.
Is the CVM required to install Oracle RAC.
Is there any alternative wherein we can install Oracle RAC without using CVM like for example using the RAW device where the VM will manage storage from a single node rather than buying the CVM that will allow to manage the storage from multiple nodes.
Also i would like to highlight is suggestion for using ASM is rule out hence ASM would not be used.
Can anyone suggest me some solution to the above problem.

Well, my impression is that you don't really know what your requirements are and you are trying to fit the technologies somehow. Worse yet, there is no clear understanding how those technologies fit together and as long as you explain what your vendor is saying you (which vendor?) they don't have clear idea either.
I would also suggest to review your decision to use Sun Network Data Replicator for DR site. Consider Oracle Physical Standby database instead - it's more flexible solution and doesn't limit your choice of storage stack.
1) Do Oracle RAC 10gR2 requires any Veritas Cluster Volume Manager
Words "any" and "Veritas" contradict in your question. But the answer is no. RAC require shared storage which can generally be one of those:
- raw devices with or without some kind of cluster volume manager
- cluster file system
- NAS storage (NFS mounted)
- ASM with raw devices for CRS files (OCR and voting disks)
2) Does Oracle RAC 10g R2 require any Vertias Cluster File System or it can sit on normal Vertias File System
Again, Oracle database files MUST reside on shared storage and non-clustered file system is not an option.
3) Is there any solution where we can use the Sun Cluster with Veritas Componets to configure RAC.
If I recall correctly, Sun Cluster includes in it's license some of component of Veritas storage stack. So you might be all set. You should turn to documentation on that stage and see exactly what you have licensed and if your stack allows shared storage. You might want to have a look at http://www.sun.com/software/whitepapers/solaris10/solaris_cluster.pdf
and Oracle Certification Matrix on Metalink.

Veritas Cluster (SFRAC) and oracle CRS

We have oracle 9i RAC running on Solaris 9 with over veritas cluster.
We want to run 10g RAC on the same same servers which will use the
veritas cluster file system
While trying to install 10g CRS the node selection list doesnt show node
information.Entered information using response file .After the installation
root.sh fails to start CRS.
Is it ok to run 9i and 10g RAC on same servers.

Chandra/Vishwa
We have a libskgxn2.so in /opt/ORCLcluster/lib directory. But the size of the file is
different from /opt/VRTSvcs/rac/lib/libskgxn2_64.so.1 file
Since we already have 9i rac running, I am not sure if copying the file from
/opt/VRTSvcs/rac/lib directory if it will affect 9i rac.
I went ahead with installation of CRS. I am getting following error while running root.sh
Checking to see if Oracle CRS stack is already configured
Checking to see if any 9i GSD is up
/oracle/crshome/AUTEST/bin/lsdb: Failed to initialize Cluster Context
skgxn error number 1311719766

Oracle Cluster Registry configuration upgraded successfully

[-hn hostA,hostAnum,hostB,hostBnum...]
With CRS and veritas running on the same server , will CRS always communicate
across nodes using VCS since we will be using veritas cluster file system
for database.

Recommendations - Oracle RAC 10g on Solaris 10 Containers Logical/Local..

Dear Oracle Experts et all
I have a couple of questions for Oracle 10g RAC implementation on Solaris and seek your advice. we are attempting to implement oracle 10g RAC on Solaris OS and SPARC Platform.
1 We are wondering if Oracle 10g RAC could be implemented on Solaris Local/Logical Containers? I was assuming that Oracle will always link it self with OS binaries and Libraries while S/W installation and hence will need an OS image/Root Disk over which it could go. However, in containers, I assume we have a single solaris installation and configuration which will thus be shared to the containers which will be further configured in it. In such situations how does Oracle instalation proceed? Do I need to look at a scenario where, the global Container/Zone will have Oracle install and this image be shared across to zones/containers accordingly? If it is so, what all filesystems from OS will need to be shared across to these zones/containers?
Additionally, even if this approach is supported, is it a recommended approach? I am unsure about the stability and functionality of Oracle in such cases and am not able to completly conceptualize. However, I assume there could be certain items which needs to be approprietly taken care off. It will help if you could share observations from your experiences.
2 The idea of RAC we are looking at is to have multiple Oracle Installations on top of native clustering solution say veritas clusters/Sun Clusters. Do we still need to have Oracle Cluster solution Clusterware (ORACRS) on top of this to achieve Oracle Clustering? Will I be able to install Oracle as a standalone installation on top of native clustering solution say veritas clusters/Sun Clusters?
Our requirement is to have the above mentioned multiple Oracle installations spread across two (2) seperate H/W platforms,say Node A and Node B, and configure our Cluster Solution to behave as active-passive across Node A and Node B. In other words, I will configure Clustering Solution like VRTS/SunCluster in Active-Passive, then have 3 Oracle installations on Node A, another 3 on Node B. I will configure one database each for each of these Oracle S/W installation (with an idea not to have Clusterware between clustering solution VRTS/SunCluster and Oracle installation, if it works). Now I will run 3 databases thus on each of these nodes. If any downtime happens on any one of the nodes, say Node A, I will fail all oracle databases and S/W accordingly to the alternate available node, Node B in this case, using native clustering solution and I will want the database to behave as it was behaving earlier, on Node A. I am not sure though if I will be able to bring the database up on Node B when resources in OS perspective are failed over.
we want to use Oracle 10g RAC Release 2 EE on Solaris 10 OS latest/one before the latest release.
Please share your thoughts.
Regards!

1 We are wondering if Oracle 10g RAC could be implemented on Solaris Local/Logical Containers? My understanding is that RAC in a Zone (Container) is not supported by Oracle, and will not work anyway. Regardless of installation, RAC needs to do cluster level stuff about the cluster configuration, changing network addresses dynamically, and sending guaranteed messages over the cluster interconnect. None of this stuff can be done in a Local Zone in Solaris, because Local Zones have fewer permissions that the Global Zone. This is part of the design of Solaris Zones, and nothing to do with how Oracle RAC itself works on them.
This is all down to the security model of Zones, and Local Zones lack the ability to do certain things, to stop them reconfiguring themselves and impacting other Zones. Hence RAC cannot do dynamic cluster reconfiguration in a Local Zone, such as changing virtual network addresses when a node fails.
My understanding is that RAC just cannot work in a Local Zone. This was certainly true 5 years ago (mid 2005), and was a result of the inherent design and implementation of Zones in Solaris. Things may have changed, so check the Solaris documentation, and check if Oracle RAC is supported in Local Zones. However, as I said, this limitation was inherent in the design of Zones, so I do not see how Sun could possibly have changed it so that RAC would work in a Local Zone.
To me, your only option is the Global Zone. Which pretty much destroys the argument for having Zones on a Solaris system, unless you can host other non-Oracle application on the other Zones.
2 The idea of RAC we are looking at is to have multiple Oracle Installations on top of native clustering solution say veritas clusters/Sun Clusters. Do we still need to have Oracle Cluster solution Clusterware (ORACRS) on top of this to achieve Oracle Clustering? Will I be able to install Oracle as a standalone installation on top of native clustering solution say veritas clusters/Sun Clusters?I am not sure the term 'native' is correct. All 'Cluster' software is low level, and has components that run within the operating system. Whether this is Sun Cluster, Veritas Cluster Server, or Oracle Clusterware. They are all as 'native' to Solaris as each other. They all perform the same function for Oracle RAC around Cluster management - which nodes are members of the cluster, heartbeats between nodes, reliable fast message delivery, etc.
You only need one piece of Cluster software. So pick one and use it. If you use the Sun or Veritas cluster products, then you do not need the Oracle Clusterware software. But I would use it, because it is free (included with RAC), is from Oracle themselves and so guaranteed to work, is fully supported, and is one less third party product to deal with. Having an all Oracle software stack makes things simpler and more reliable, as far as I am concerned. You can be sure that Oracle will have fully tested RAC on their own Clusterware, and be able to replicate any issues in their own support environments.
Officially the Sun and Veritas products will work and are supported. But when you get a problem with your Cluster environment, who are you going to call? You really want to avoid "finger pointing" when you have a problem, with each vendor blaming the cause of the problem on another vendor. Using an all Oracle stack is simpler, and ensures Oracle will "own" all your support problems.
Also future upgrades between versions will be simpler, as Oracle will release all their software together, and have tested it together. When using third party Cluster software, you have to wait for all vendors to release new versions of their own software, and then wait again while it is tested against all the different third party software that runs on it. I have heard of customers stuck on old versions of certain cluster products, who cannot upgrade because there are no compatible combinations in the support matrices between the cluster product and Oracle database versions.
I will configure Clustering Solution like VRTS/SunCluster in Active-Passive, then have 3 Oracle installations on Node A, another 3 on Node B. As I said before, these 3 Oracle installations will actually all be on the same Global Zone, because RAC will not go into Local Zones.

Oracle RAC 10g on Solaris x86 using vmware

Guys,
I am practising 10g RAC installation on my laptop, wherein I have vmware workstation and

Can you provide some sort of clue what could be done to resolve the above error?

Refer to http://www.oracleracsig.org/ Under documents section select OS=Solaris. You will find a document on Oracle RAC on Solaris10 using Vmware.
