MSCS for 4.6C and Oracle10 on winx86_64

Hello guys

We have to install SAP R/3 4.6C clustered by MSCS.


SAP R/3 4.6C

SAP Kernel 4.6D EXT 32 bits


Windows x86_64

We did preparations regarding to MSCS

We have already installed succesfully SAP R/3 4.6C in one of nodes of cluster. SAP system is ok.

Now we have doubts in phase Clustering. Documentation is confuse...

As per note 975467 - Oracle 10g Support on Windows: 4.6D-Based SAP Systems, we find:


o Do not use the following chapters from the installation guides for

your 4.6D-based system:

"Installing the Oracle Database Software",

"Installing the Oracle Failsafe Software",

"Converting the DB to a Fail Safe DB"

Use the respective chapters from the installation guide for SAP

Netweaver 2004s SR1 instead:

"Installing the Oracle Database Software",

"Installing the Oracle Failsafe Software",

"Additional Steps for the Oracle Fail Safe Configuration",

"Creating the Oracle Fail Safe Group",

"Setting Up a Shared Database Directory in Oracle Home",

"Adding the Oracle Database Resource to the Fail Safe Group".


So ,it seems is necessary use Chapters of guide of Netweaver...

and then, in last point we find:


If you plan to set up a Microsoft Cluster Service (MSCS)

configuration of 4.6D on X86_64, refer to SAP Note 955785 for more



So , we read note 955785 and we find:


Do not use the "Start - Programs" entries to start the clustering

steps: "Configuring MSCS Node A", "Configuring MSCS Node B",

"Completing MSCS".

Use "R3Sedit.exe" instead and load the templates NTCMIGNA.R3S,



So it seems clustering must be done using secuence of 4.6C guide, but some points must be replaced by tasks of Netweaver guide.

But The thing is that sequence of steps to Clustering in release 4.6C is not the same than in Netweaver.... all of this is confused...

Please could you tell me which steps are necessary to clustering SAP R/3 4.6C , Oracle 10, with MSCS and in which order?

Thanks and regards

    that is correct:

    1) you use "guide of Netweaver" to install and cluster Oracle software.

    The difference to 32-bit is that you install 64-bit Oracle and OFS software, but you will install 32-bit OFS client.

    2) you use notes 814834 and 955785 to install CI, load data and cluster the CI.
