SAP Cluster Installation instance number issue

[Former Member]

Hi,

We had some problem about the sap cluster installation .

OS : AIX 6.1

Database : DB2

We are trying to install the sap cluster under AIX + DB2.

But we are not sure whether we have

CI instance = 00

DI instance = 03

will it have problem . ( e.g. will we need to adjust the transport

configuration eachange due to the instance number different )

Because we had saw other case on window which is

CI instance = 00

DI instance = 00

So which is working fine and no problem.

Please help and give some recommendations. We would like to confirm is window / aix the same , are there any concern here( CI instance is need to different

with DI or not , if not what will be affect. ) .

Regards

Hello!

You CANNOT run two instances with the same instance number at the same server!

If you have two different servers, one instance per server, then it's OK to use the same instance number.

Hi,

It is recommended to choose different system number for each instance of single SAP system.

You can use as follow:

for ASCS = 00

CI = 01

DI = 02

I have used it many times without any problem.

Hi,

You can choose different system numbers for CI and DI. It will work perfectly fine.

Scenario in case of window where system numbers are same also fine.

Thanks
