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...

When is Oracle Adapter for SAP 10.1.2.0.2 released?

Hi,
I'm desperately waiting for the release of the Oracle Adapter for SAP
10.1.2.0.2. It is stated as Projected on the Download site.
I do still have serious problems with bug 2574376. This bug was fixed already
in July 2004. In that bug is stated that it is fixed in 10.1.2.
I am using the workaround to kill the process. But when I kill the process while the
adapter is processing data for update in SAP, I am losing that data. So the
update does not take place in SAP and the data is not in the persistence
anymore.
So please release this version!
Regards,
Aard-Jan

Yes, but not for HPUX jet. And that is what I need.
Via Metalink I heard that it will be available around august.

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;

RAC for SAP

Hi,
Many of the job requirement are asking for Oracle RAC experience on SAP.
Does any one have experience on that.
If so please share their experience.
Few years back I attended course on SAP Basis and as I remember most of the DBA tasks will be done through SAP interface.Not sure how it can be done for a RAC database.
Please advice.
Thanks in advance.

Hi,
Well, I worked in a shop that used OPS (predecessor to RAC) with SAP, and it did not work out too well, we went back to a single instance configuration . . . . .
I think that OSS has a note on using RAC with SAP, I would start there . . . .
Hope this helps. . . .

Configuration of Oracle RAC for windows

Hi all
We are planning to test a RAC solution for our NW04S solution.
We want to install RAC for oracle database and use the RAC HA solution to implement enqueue service replication.
I ve found a document for installation on Unix which make a reference to a windows document guide.
i wasnt able to find it.
Any clues about this installation ?
thanks a lot

Yes, I do
Here is an exceprt of the SAP note 971289 (Protection of Enqueue Replication through Oracle Clusterware) :
"Use of Oracle 10.2 with the Real Application Clusters (RAC) option and Oracle 10.2 clusterware on a clustered Linux or AIX platform."
P.S. You can anyway use MSCS for replicated enqueue

How to configure Oracle RAC for Wiki and Blog

Has anyone done Oracle RAC configuration for Oracle Wiki and Blogs?
Thanks,

Hi Andreas,

Set events parameter in oracle 11g for SAP

Hi All,
Recently we have upgraded 10.2.0.4 oracle database to 11.2.0.3 (AIX 7.1) for SAP application.
Some non-default event parameters were set when Database was running with 10.2.0.4 version. After upgrade to 11.2.0.3, those events were not seen in pfile/spfile. However, post_upgrade log shows that those events were set (and log displays the list of the events as well).
Now, my concern is whether those event parameters were set already by default (if it is already set after upgrade, not sure why pfile not reflecting them) or do I need to set the parameters manually.
Thanks in advance for all your help.
Regards,
Prakash

Yes, they seem to be part of the upgrade itself, and SAP seems to set them in multiple places:
1) During the dbua.sap.sh run, post-processing calls custom scripts which set these events (check the CustomScript.log in $ORACLE_BASE/cfgtoollogs/dbua/SID/upgrade1 and you can see where it is set)
2) The post_upgrade_status.sql script in $ORACLE_HOME/sap/ora_upgrade/post_upgrade sets them when you run it as directed after the upgrade
3) The SBP post-patch instructions specify a command to run that sets these in the spfile
I don't think any of the upgrade steps regenerate the pfile, so if you're looking at one you generated pre-upgrade (like I did earlier today to pull out underscore parameters and user/background_dump_dest) that you then used to startup the database, SAP is definitely changing stuff behind your back. I'd just regenerate the pfile to avoid confusion.

Oracle Adapter for SAP

Respected Guys
I have an oracle-9i database connected with SAP and wants to transfer data from oracle9i database connected with SAP to an another oracle-9i database which is connected with a GPRS system.
Data about only sales has to be transfered from SAP to GPRS database (Oracle9i). I want to know the procudre of transfering data from SAP to GPRS database.
I know there is an Oracle9i Adapter which is used for this purpose. Anyone know about how to use the Idocs or ALE for this purpose.Or if anyone is aware of use of Oracle9i Adapeter. We are using Oralce9i with SAP4.6 and the database connected with GPRS is also oracle9i.

Hi,
I checked the following document under the section: Adapter Features / Supported Versions and Platforms.
Oracle® Application Server Adapter for SAP User's Guide 10g Release 3 (10.1.3.1.0)
I could find that the SAP 6.0 is supported by the adapter that comes with OAS 10.1.3.1

Just started supporting Oracle Databases for SAP Systems

Hello Guys/Girls,
I am working as oracle dba for the past 7 years, but this is the first time, I got an opportunity to adminster databases supporting SAP systems. I am doing search on SAP Network, and gathered information on BRTOOLS, SAPGUI etc., but could not find the details what I am looking for like, database objects growth rate, sap-oracle database performance specific details, as a oracle dba what are the DOs&DONTs etc., After made a lot of search on google, I found a book from O'Reilly, but that book covers older SAP, and Oracle versions. Our Client uses oracle 9i, and 10g primarily.
I am confident as a Oracle DBA supporting non-sap systems, but not SAPsystems. Is any one of you pls., suggest me or provide me some guide lines in terms of Database Management.
Appreciate your time!

Abhi
Greate to meet another DBA in forum.The big problem we will face is SQL Tune.
Nothing much Diffnt supporting SAP.SAP PRovided some ready made tools to monitor and to solve.Reg tuning still we can follow same methoda but with approval from SAP or by ref SAP notes.Which u can find at service market place.
You can find some PDfs in sap market place and sdn.Which are ex'ly for DBas.
Reg Growth rate you can have a look on sap transactions and there are some notes also.I dont think there is specific Book or Doc which will say Dos and donts.
Performance we used to follow same methoda as a Dbas with ref of sap notes and support for any side effects.
let me know if are in need of any specific info

Oracle Client for SAP NetWeaver 7

I am pretty new in this area and wondering whether a new installation of SAP NetWeaver 7.0 Central Instance on Linux needs Oracle RDBMS 10g Client from SAP or it can be obtained from Oracle (Instantclient)?
Thanks.

Hi,
The instantclient from Oracle and from SAP are the same (note, only the instantclient, 10g, no other previous oracle client version)

If you do not have the file OCL10264.SAR, then you can download the file from SAP, no need to download it from Oracle (why that need of downloading from Oracle?)
You can take a look at your installation CDs, the file is also located there. No need to download it from anywhere.
Recommendation, unless for an explicity reason (like a note indicating it or a message with the same indication) do not download/install anything that is not available in an SAP website

Recommended Oracle version for SAP 4.7 and for BW 3.5

Hi,
where I can find the SAP's recommended version of Oracle for SAP ERP 4.7 and BW 3.5?
Thanks
Message was edited by:
giovanni maria maccioni

Hi,
Recommended would be 10.2.0.2
Oracle has ended the customer care support for 9.2 in July 2007:
Note 925871 - Discontinuation of 'Customer Care Support' for Oracle 9.2
At the same time, SAP customers have a "free" year of Extended Support for Version 9.2.
9.2.0.8 is the latest patch set provided for 9.2. (see note 1021844)
I think that, if you are planning to perform a new installation, it would be better to do it in 10.2

Hi Elmar,
I have checked the packages and the XFree86-libs-4.3.99 is not installed. I guess I will have to install it.
Now your question about oracle user. I am not sure if you have performed any SAP MDM installation with ORACLE RDBMS but the installation guide is totally different than the normal SAP inst guides. Indeed someone needs to install separately SAP MDM and ORACLE and in my installation I do not install NetWeaver since it is not mandatory for the testing phase of the project. You can have a look at the guide (it is very poor -no reference to ORACLE details):
https://websmp105.sap-ag.de/~sapidb/011000358700000271882007E
So the official ORACLE inst gudie says to install the ORACLE software with the oracle user.
Rgds,
Louka

OracleAS Adapter for SAP

my plan is to extract data from the current Oracle sales and distribution Legacy system into txt file with IDOC format, my question is (since I do not have the SAP experience), how this file will get uploaded into the SAP system through the Oracle AS Adapter .

I have resolved this issue with the help of Mr Hugo Garzon through metalink.
Re-installed (As my installation was worng):
1.Oracle SOA Suite 10.1.3.1.0
2.Oracle Adapter 10.1.3.1.0
Follow the below mentioned steps to resolve the Jdeveloper issue:
1. Modify the collaxa-config.xml ($SOA_ORACLE_HOME/bpel/system/config/) the "ApplicationsWSDLHome" property
before you restart
the server. This property must to be equal to $SOA_ORACLE_HOME/adapters/application/wsdls/
2. This issue is documented in this bug, the Bug 6153919 UNABLE TO BROWSE THE OEM ADAPTERS WSDL IN THE
10.1.3.3 JDEV, in there appears a workaround: In JDeveloper please expand the
created Integration Server Connection before browse the WSDL, after his action,
you will see the Adapter services.
Thanks a lot Hugo for your valuable help.
Cheers,
Shanty
