SAP on Oracle RAC+ASM 11g - SWPM installation Option

Dear Experts,
I came across SAP Note 1977393 which is describing the installation steps of a RAC installation with SWPM with an example.
However, the note is not describing the exact preparation steps to be performed on the cluster nodes.
For example, the note doesn't describe if it's required to install the Oracle Grid Infrastructure on the Cluster Nodes before using the SWPM with the RAC+ASM option.
Thanks in advance.

Install SAP cluster ORACLE RAC and SCS

I need to install SAP ECC SR3 in an environment in cluster.

My doubt is the following one: Which the steps that I have that to follow so that everything of certain.
When I go to install ORACLE RAC? Before, later or during the installation of SAP?

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,

Does /sapmnt need in cluster file system(SAP ECC 6.0 with oracle RAC)

We are going to be installing SAP with Oracle 10.2.0.4 RAC on Linux SuSE 10 and OCFS2. The Oracle RAC documentation states:
You must store the following components in the cluster file system when you use RAC
in the SAP environment:
- Oracle Clusterware (CRS) Home
- Oracle RDBMS Home
- SAP Home (also /sapmnt)
- Voting Disks
- OCR
- Database
What I want to ask is if I really need put SAP Home(also /sapmnt) on cluster file system? I will build a two nodes oracel 10g RAC and I also have another two nodes to install SAP CI and DI. My orginial think is sapmnt is a NFS share, and mount to all four nodes(RAC node and CI/DI), and all oracle stuff was on OCFS2(only two rac nodes are OCFS), anybody can tell me if SAP Home(also /sapmnt) can be NFS mount not OCFS2, thanks.
Best regards,
Peter

Hi Peter,
I don't think you need to keep /sapmnt in ocfs2 . Reason any file system need to be in cluster is,in RAC environment, data stored in the cache of one Oracle instance to be accessed by any other instance by transferring it across the private network and preserves data integrity and cache coherency by transmitting locking and other synchronization information across cluster nodes.
AS this applies to redo files, datafiles and control files only , you should be fine with nfs mount of /sapmnt sharing across and not having ocfs2.

Oracle RAC + Clusterware and another Cluster with Clusterware for SAP

Hi,
I have some questions about implementation of Oracle RAC and Clusterware with SAP
For exemple, an architecture with 4 servers ( 2 real and 2 vritual ).
I would like to know if i can do this
2 servers for the first cluster.
First cluster is with Clusterware and Oracle RAC
This is for all the SAP Oracle databases environment
I think there is no problem here.
Now, with 2 others servers il would like to make another cluster (with also clusterware ) for SAP Central services (SCS) and enque replication server (ERS)
Because all architecture is for only one SAP environment with separate services.
1 for Database (cluster 1)
1 for Central services ( cluster 2, virtual machine )
1 for Dialogue Instance (no cluster)
To be clear, the second cluster is to make HA of central services SAP (SCS and ERS )
My question 2 are :
Is it a good job to do this ? or there is anything wrong ?
Do i have to install antoher clusterware for this 2 servers or i have to make anything with the existing clusterware + oracle RAC ??
Thank you very much for you help

Hi Givre,
have you checked: Providing High Availability for SAP Resources (http://www.oracle.com/technology/products/database/clusterware/pdf/sap-availability-on-rac-twp.pdf) available on otn.oracle.com/clusterware? Not being an SAP expert myself, I still think, this paper describes the configuration - at least partially - that you are trying to set up.
Just an idea. Thanks,
Markus

SAP ECC6.0 installation with Oracle RAC

Hi Expert,
Current we working on SAP ECC6.0 installation with Oracle 10G RAC on AIX 5.3. The RAC are running on two nodes (servers). And we are using GPFS filesystem (not running on HACMP).
Overall we had completed the Oracle RAC installation (CRS+RDBMS) and tested the oracle failover and it work find. Now we want to start with the SAP installation (with HA). In the SAP installation documentation, it did request to create a virtual hostname on the node and execute the sapinst scripts with below command line.
#./sapinst SAPINST_USE_HOSTNAME=ascs00
But if we are running on Oracle RAC + GPFS do we need to specify the virtual hostname? If not, which hostname i should use to install the HA for SAP? Please advice.
Regards.

And then I'd continue with the documentation at:
SAP on Oracle => SAP on Oracle Real Application Clusters (RAC)
There you can find several installation guides for windows/UNIX/Linux

Configure RAC for SAP on Oracle database

My client has SAP installed on oracle 10g database, they want me to configure RAC so that 4 other servers will share the same database as the the production database.
can anyone guide me on how to go about it
I have already installed SAP on the 4 other servers and exported the database into the new server. can anyone guide me on how to configure RAC for oracle 10g database?

Hi,
You can find the related information, under the link below;

I recommend you to read the document, Oracle 10g RAC on SAP Netweaver;

SAP - Oracle RAC - Linux - VMware

Hi,
we would like to install SAP on a virtual environment (VMware) on Linux RedHat platform.
For the database, Oracle RAC is certified with OCFS2 (1.6) only with Oracle Linux and not RedHat Linux 5.
Can we intstall Oracle RAC database on 2 nodes with Oracle Linux and OCFS2 and other SAP components on Redhat Linux 5 ?
Are there any issues with SAP matrix compatibility ?
Thank you!
Dan

Hi Audun,
Thank you for the links.
I can see the ASM support is new (2.2.2011)
On Note 527843 from 25.01.2011 - Oracle RAC support in the SAP environment
Using raw devices and ASM (Automatic Storage Management) is not supported in the SAP environment. In the case of ASM, there is an exception regarding the Oracle Cluster Registry (OCR) and the voting disks
and
on Note 1550133 - Oracle Automatic Storage Management (ASM) from 2 Feb 2011 they support ASM but with restrictions:
ACFS is required for RAC installations with ASM
To use ASM now, you have to migrate your database to ASM manually
Some important functions of SAP BR*Tools like backup, restore, recovery, tablespace and datafile management are not supported at the moment
Support for tablespace and datafile management is planned for Q2/2011
Also ASM instance will introduce another layer in the system with its problems, failures and resources consumption. I see on the Oracle Metalink alot of problems related to ASM. From the marketin point of view is ok, let's oracle do everything but I think if you will keep it simple it will be better.
I didn't figure out if you can directly install Oracle 11.2.0.2, they say "Allows direct SAP system installations with Oracle 11.2"
We have a vBlock hardware with flash disks as FAST Cache so I believe with 1TB of cache IO will not be a problem.
Thank you!

Oracle RAC One with SAP?

Hello,
are there any plans to release RAC One with SAP?
Will it be included in the general Oracle RAC 11.2 release for SAP?
Who can tell me the (list) price for Oracle RAC One for SAP systems?
The note 527843 doesn't help with any of these questions.
Regards,
Mark

Hello,
I am especially interested in the licence policy of RAC One.
Will it be part of standard or extended licence ???
Generally RAC One is an Oracle Option that just limits the RAC with 2 nodes.
If SAP makes certification for "RAC" generally and not for "RAC One" this would be
no technical reason.
If somebody authorized can answer my question this would be great.
Best Regards
Andreas

Migrating single instance SAP and Oracle 11.2.0.1 database to Oracle RAC

We have a single instance SAP Netweaver environment on Oracle 11.2.0.1 database and want to migrate to Oracle 11.2.0.1 RAC and ASM. The documents are for 11.2.0.2 and later but we want a way to:
1. Migrate single instance SAP and Oracle 11.2.0.1 instance to ASM
2. Configure the environment as four node Oracle 11.2.0.1 cluster
Thus far, I have:
1. Installed clusterware 11.2.0.1
2. Installed four ASM instances
My questions:
1. We want to migrate the single instance database to same server and extend to four node cluster and ASM
However, current SID for SAP and Oracle must remain the same. The problem I have is that the target database name needs to be same as source on same physical host.
2. How would I use RMAN to migrate the single instance database to ASM for 11.2.0.1?
3. How would I use rconfig after this step?

1- We have single instance Oracle 11.2.0.1 database using file based datafiles, archivelogs, controlfiles, etc on single RHEL5 Linux host
2- We have four available Oracle 11.2.0.1 ASM instances on four RHEL5 Linux hosts
3- We have installed four node Oracle 11.2.0.1 clusterware on the above nodesAnd what is the shared storage? For RAC, all shared storage devices for the cluster need to be available and usable by all ASM instances in that cluster.
Issue- we have RAC 11.2 clusterware listener using SCAN and listeners for all four clusterware nodes.
When we try to run the following RMAN command to migrate the single instance Oracle 11.2.0.1 datafiles it fails:The failure says: "+RMAN-10038: database session for channel ORA_DISK_1 terminated unexpectedly+". And this in itself does not tell you what the actual problem encountered is.
4- How to register the single instance with all four ASM instances and network services to resolve the above issue?Register what instance? ASM does not need databases or instances to be registered. It is a storage management layer. The cluster (grid infrastructure) layer is the one that deals with the registration (and management) of the various services and resources on that grid (e.g. ASM instances, database instances, SCAN and VIP, Listener services, etc).
5- Do we need to first run rconfig utility against single Oracle 11.2.0.1 instance to register with clusterware services BEFORE using RMAN to perform the datafile migration to ASM?Never used rconfig. See Support Note +RCONFIG : Frequently Asked Questions [ID 387046.1]+ for details.

Usin Oracle RAC for SAP

Hi All,
Can Oracle RAC be used for SAP ECC 6.0 and if so is it recommended?
Thanks and regards.
Iqbal

Did you search a little bit? Check the follwing link here in the SDN:
SAP on Oracle
First line on that page:
"Oracle RAC with SAP is generally available"
SAP does neither recommend an operating system nor a database or any other technology. They either "support it" or "do not support it".
What is the purpose you want to implement RAC? Availibility? Scalability?

Oracle RAC for SAP on Linux and OCFS

We are going to be installing SAP with Oracle 10.2.0.4 RAC on Linux RHEL 5.2 and OCFS. The Oracle RAC documentation states:
You must store the following components in the cluster file system when you use RAC
in the SAP environment:
- Oracle Clusterware (CRS) Home
- Oracle RDBMS Home
- SAP Home (also /sapmnt)
- Voting Disks
- OCR
- Database
I'm curious about the requirement of installing the Oracle Home on shared clustered filesystem. In other RAC installations I've built, I installed the binaries on local filesystems on each node. This is to facilitate the concept of rolling patches. With the SAP's requirement, it appears rolling patches are out of the question. Can someone enlighten me on why SAP requires the Oracle Home reside on shared filesystem.
Thanks

We have even put /oracle/SID on OCFS, because the brtools cannot cope with local FS. If you take a backup on node1, then you cannot restore it from node2. Or you could start multiple brconnects at the same time (this is normally prevented with a lock file). Of course you could run all your all your br commands on a dedicated node, but this doesn't fit the RAC idea much.
Just my two cents, of course this does not fully explain, why the ORACLE_HOME has to be shared as well.
Best regards, Michael
Edit: Ahh, now i recall, i really think it is because of the BR*Tools, they need the initSID.sap file in ORACLE_HOME/dbs. This implies that it won't be a big thing to get SAP on RAC running with local ORACLE_HOME's, but that doesn't help a lot as long as SAP does not officially support it...

Install SAP ERP 6.0 with Linux and Oracle RAC

Hi Guru,
I want to install SAP ERP 6.0 with Linux and Oracle RAC. Is this possible?
Where do I find information?
Thanks,
Hugo.

Hello Hugo,
You can use either RAC or dataguard. On note [105047|http://service.sap.com/sap/support/notes/105047]:
14. Data Guard
    o You can use "Physical Standby".
    o You cannot use "Logical Standby".
    o You can use Data Guard Broker.
    o You can use Maximum Performance Mode, Maximum Availability Mode and Maximum Protection Mode.
    o In the case of Maximum Availability and Maximum Protection, you must pay particular attention to a fast network connection in order to avoid performance problems.
    o Maximum Protection causes the primary database to terminate if problems occur in the standby database.
60. Real Application Cluster (RAC)
    o You can use this feature in accordance with Note 527843.
Regards,
Eduardo Rezende
