Installing 4 SAP R/3 instances on one Windows host.

[Former Member]

Hi Experts,

I have been assigned task to install 4 SAP R/3 instances on one Windows host in which 2 instances are already installed successfully & running with no issues. I need to install another 2 instances for DEV & QA on the same system by upgrading the RAM & Storage.

Below are the configuration of my system.

Processor: - Intel Xeon 3.4 Ghz 2 Quad Core

Storage: - Existing 146*4=584 GB

Upgrading to 146*8= 1168GB

RAM: - Existing 4GB

Upgrading to 12 GB.

Operating System: - Windows 2003 Standard Server Edition 64bit R2

SAP Application: - SAP R/3 4.7 Enterprise Edition SR1

Database: - Oracle 10g

I want know is this possible ? can 4 instances run on one Windows host ?

Thanks,

Shambo

As long as you don't expect great performance... I can't see why not. I't will be a logistic nightmare to try restarting the DB.

Why don't you just get another box?... seems like you have budget for spare hardware.

This is certainly not recomended for a production environment.

Hi Juan,

Thanks for quick repy.

This is for Development System. As there are some budget contraints. I know it is not recommended but just want to check about the possiblity on given hardware configuration.

I am planning to install the 4 Central Instances 2 for DEV & 2 for QA. I am worried about the Database instance as 4 different Oracle Homes will be installed....

Thanks,

Hi,

We do have some servers with 4 R/3 4.7 system on Windows 2003 IA64 with Oracle 9.2.0.7.

We have 32 GB of RAM on the server.

We install 4 separate Oracle databases.

It works great. The only problem is that we have "all eggs in the same basket". when the server is down, we have 4 systems down...

But we were required to lower the number of physical servers.

We also installl now all oour application servers on VMWARE virtual servers.

Hi Olivier,

Thanks for your reply!

Can you give me the hardware configuration which you have??

I have installed Windows 2003 Standard Server edition 64bit R2 will it support this kind of installation on AMD64 processor??

Hi again,

For 4 SAP R/3 4.7 systems on the same server

we have 2 different kinds of servers :

8 Itanium processors, 32 GB RAM, 5 TG disks, Windows 2003 IA64

4 Xeon quadri-core (16 cpu cores) , 32 or 64 GB RAM, 5 TB disks, Windows 2003 x64

>Windows 2003 Standard Server edition 64bit R2

Check the PAM, I think I remember that Enterprise edition is needed...

Check the PAM, I think I remember that Enterprise edition is needed.

not anymore. Standard edition in 64-bit mode supports up to 32GB of RAM.
