Oracle RAC v Veritas HA

Hello.
We currently use Veritas for high availability in our SAP environment. A two node cluster.
I am confused in regards to the capabilities of RAC. Is that not just a high availability solution just for Oracle? Why would I think about going to RAC if I have Veritas HA?
Thanks in advance for any thoughts shared.

> I am confused in regards to the capabilities of RAC. Is that not just a high availability solution just for Oracle?
Hi there,
RAC is not just a HA solution but a active/active cluster that makes scaling of the database in terms of processing capacity possible.
If you add a node to a RAC cluster all nodes work on the same database at the same time.
That way it is possible to have more processes working on the database in parallel.
Since this is a rather broad topic you may review your requirements before considering a move to RAC.
regards,
Lars

CRS10g patchset을 적용한 이후 Veritas SF Oracle RAC 관련 MODULE

Problem Description
다음은 SF(Storage Foundation) Oracle RAC를 구성하기 위하여 Oracle CRS
PATCHSET 등을 적용하기 전에 SF Oracle RAC Veritas libraries 를 ORACLE_HOME에 설치해야 한다는 내용입니다.
또한, ORACLE CRS 패치 Version 을 올리면서 Veritas 쪽 관련하여 필요한
Veritas skgxp module 등이 설치 과정에 빠져 있거나 Veritas library file들이 overwrite되어 에러를 만나는 경우를 볼 수 있습니다.
이런 관점에서 Veritas storage foundation 을 설치하고 oracle CRS stack을
설치 또는 갱신하는 과정에서 만날 수 있는 에러에 대해 원인 및 해결방안을 알아봅니다.
에러 증상
다음은 CRS 10.2.0.3.0 Patchset이 설치되면서 Veritas library가 overwrite 되면서 발생하는 에러임.
Veritas clusterware 5.0 not recognized by Oracle due to the fact that Veritas libraries over written with crs 10.2.0.3.0 patchset installation.
The cssd.log shows:

원인
새로운 CRS patch 관련 변경이 있은 이후에 Veritas SFRAC 관련 module이 인식되지 못하는 문제 야기됨.
Installing and Configuring SF Oracle RAC Software
Veritas 에서 제공하는 Storage/Clusterware 관련한 절차는 이 문서에서 생략합니다.
Install CD 안의 installsfrac 스크립트 수행 session 에서 RAC software installation을 하는 과정이 들어갑니다.
Veritas가 제공하는 SF Oracle RAC 5.0 installation 문서를 보면 다음과 같은 내용이 포함되어 있습니다.
아래 내용에는 SF Oracle RAC component 들을 설치하는 과정만 기술합니다.
# cd /cdrom/storage_foundation_for_oracle_rac
# .installsfrac -configure
Note: Do not run root.sh yet, but return to the installsfrac session from step 15.
19 In the installsfrac session, press Return. The installsfrac utility now verifies
the database software installation, copies the SF Oracle RAC libraries to $ORACLE_HOME, and relinks Oracle on each node in the cluster.
다음은 위와 같은 installsfrac 스크립트를 수행한 이후에 Installer가 5.0 SF Oracle RAC library file들을 ORACLE_HOME으로 Copy하는 과정이고, Oracle library file들을 relink합니다.

Before you run the root.sh script, you need to add the init.cssd.patch.
a. Open another window on the system where you are running the installer
b. Log in as superuser
c. Change to the directory where the patch is to be copied:
For Oracle 10gR1:
# cd $CRS_HOME/css/admin
# cp /opt/VRTSvcs/rac/patch /init.cssd-10gR1.patch .
For Oracle 10gR2:
# cd $CRS_HOME/css/admin
# cp /opt/VRTSvcs/rac/patch /init.cssd-10gR2.patch .
d. Run the following command to install the patch:
For Oracle 10gR1:
# patch < init.cssd-10gR1.patch init.cssd
For Oracle 10gR2:
# patch < init.cssd-10gR2.patch init.cssd
e. Run the root.sh script. For example:
# cd $CRS_HOME
# ./root.sh
This starts the CRS daemons on the node where you enter the command.

Oracle Upgrade from Oracle RAC 9.2.0.6 to Oracle 10.2.0.4

Hi All,
Currently, we are running 4 node Oracle RAC environment with below mentioned configuration.
OS: Sun Solaris 5.9
Hardware: Sun E2900
Oracle Version: 9.2.0.6
Veritas Cluster Server: 4.1
We want to upgrade Oracle version to 10g, and currently analyzing the options to perform this. The current database size is 1TB appx and we want to spend minimum application shutdown time running on this database.
As part of upgrade, we also need to upgrade Veritas Cluster Server from 4.1 to 5.1 to support Oracle 10g. It would be great help,, if someone can pass some guideline to perform this task.
We are currently thinking about piecemeal approach, where we can upgrade each node individually and then put them back to cluster. There are some complexities involved, and its really high risk approach.
Thanks a lot in advance for help
Regards,
Manoj

Orcale 10g RAC requires you to install Oracle Clusterware. Oracle Supports running it along side a 3rd party clustering software. Not sure why you're so anxious to upgrade Veritas Clusterware when it will be trivial on the 10g db hosts.

SAP R/3 on Oracle RAC

Hi,
I would like to know some info about configuring SAP R/3 for Use with Oracle Real Application Clusters, especially on Veritas Advanced cluster, any doc link provided will be appreciated.
Thanks.

Hi,
I believe Veritas Advanced Cluster 4.0 is available in Solaris (Fujitsu Siemens) or Solaris (SUN), both Oracle 9i and 10g support it. For more related docs, you can go to:
http://service.sap.com/dbaora -> Media Library -> Oracle RAC
And go to Cluster documentations for your specific Platform partner, also otn.oracle.com.
Hope this helps,
George

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 on Solarais Configuration Issue

Hi,
We are trying to install Oracle RAC 10g R2 on Solaris 10.
Following are the products
1=> Soalris 10 OS
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.

Does oracle clusterware and oracle RAC require sun cluster

Hi,
I have to setup oracle RAC on solaris 10 SPARC. so is it necessary to install sun cluster 3.2, QFS file system on solaris
I have 2 sun sparc servers with solaris 10 installed on it and shared LUN setup(SAN disk RAID 5 partitions)
Have to have 2 node setup for RAC load balancing.
Regards
Prakash

Hi Prakash,
very interesting point:
As per oracle clusterware documents the cluster manager support is only for windows and linux.
In case of solaris SPARC will the cluster manager get configured ???
The term "Cluster Manager" refers to a "cluster manager" that Oracle used in 9i times and this one was indeed only available on Linux / Windows.
Therefore, let me, please, ask you something: Which version of Oracle RAC do you plan to use?
Because for 9i RAC, you would need Sun or Veritas Cluster on Solaris. The answers given here that Sun Cluster would not be required assume 10g RAC or higher.
Now, you might see other dependencies which can be resolved by Sun Cluster. I cannot comment on those.
For the RAW setup: having RAW disks (not raw logical volumes) will be fine without Veritas and ASM on top.
Hope that helps. Thanks,
Markus

dont think you need nb_ora_serv unless the NBU software didnt know where to send the backups but it should.
in netbackup admin console, look at the job activity and watch and see does a connection come in from the NBU client, the client being the server where the database resides
have you ever succesfully backed anything else from RAC to NBU? Took me ages first time to get it right.

In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?

In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?

The query is re-issued as a flashback query and the client process can continue to fetch from the cursor. This is described in the Net Services Administrators Guide, the section on Transparent Application Failover.

I had this problem and resolved it by transporting the file to the installation server with the correct ftp datatype (binary).
On page 54 of the install guide (..Server\Oracle_Business_Intelligence\doc\doc\bi.1013\b31765.pdf) that comes with the installation files, there is an instruction to make sure that any ftp activity is done in binary.
This may not have occured with the license.xml file if you use a tool which offers the "feature" of automatic datatype recognition.
Hope this helps.

Try this. It worked for me.
Please keep in mind that you will need wait till each step finishes successfully before move to next one
For Step1 and 2, you can skip node(s) on which you didn't execute root.sh yet.
Step 1: As root, run "$GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force" on all nodes, except the last one.
Step 2: As root, run "$GRID_HOME/crs/install/rootcrs.pl -verbose -deconfig -force -lastnode" on last node. This command will zero out OCR and VD disk also.
Step 3: As root, run $GRID_HOME/root.sh on all node one by one

Hi Andreas,
Thanks you for your help. I am trying to implement third party external LDAP authentication for APEX and Forms.
So I started with OID and SSO setup to create external Partner Applications. Some reason my oid and sso web login links are not working. I didn't find any errors. I need some help in finding the problem and direction, I already read docs on web but no proper direction. I appreciate your help.
Thanks

Oracle RAC with ASM install failure

Hi Guy's
I've just rebuilt an Oracle RAC system, i've built this system many times and have the build documented. I usually follow the build doc to the tee and everything works fine. I have now been asked to rebuild the system to go into the production evironment. This is a two server standard RAC setup using ASM. We have a HP MSA500 shared storage setup. I've run the cluster verification tool and all the checks have come out fine. Whilst installing the clusterware i get a failed error message whilst it try's to confiure the Oracle Clusterware Configuration Assistant.
The error message i get is:
Command = C:\Windows\system 32\cmd\C Call E:\Oracle\Product\10.2.0\crs\install\crssetup.config.bat
PROT-1:Failed to intialize OCR Config
STEP 1 Checking status of CRS cluster
STEP 2 Creating directories (E:\Oracle\Product\10.2.0\Crs
STEP 3 Configuring OCR repository
ocr upgrade failed with (-1)
I've done this build many times and never seen this error. From what i've read on the internet it looks like it could be something up with my shared storage but i dont know what.
Any help would be greatly appreciated
Thanks
Lee

ASM instances on 2 node Oracle RAC 10g r2 on Red Hat 4 u1

Hi all
I'm experiencing a problem in configuring diskgroups under +ASM instances on a two node Oracle RAC.
I followed the official guide and also official documents from metalink site, but i'm stuck with the visibility of asm disks.
I created fake disks on nfs with Netapp certified storage binding them to block device with the usual trick "losetup /dev/loopX /nfs/disk1 " ,
run "oracleasm createdisk DISKX /dev/loopX" on one node and
"oracleasm scandisks" on the other one.
With "oracleasm listdisks" i can see the disks at OS level in both nodes , but , when i try to create and mount diskgroup in the ASM instances , on the instance on which i create the diskgroup all is well, but the other one doesn't see the disks at all, and diskgroup mount fails with :
ERROR: no PST quorum in group 1: required 2, found 0
Tue Sep 20 16:22:32 2005
NOTE: cache dismounting group 1/0x6F88595E (DG1)
NOTE: dbwr not being msg'd to dismount
ERROR: diskgroup DG1 was not mounted
any help would be appreciated
thanks a lot.
