High Availiability

Hi

We are planning for HA in our project. Our SAP setup is as below..

I have gone thru the Installtion manual and collective note on HA

-- it is a 3 system landscape with HA for production server.

-- AIX - 5.3, ORACLE 10G, SAP SR3, dual stack (ABAP + JAVA)

We are going for 2 sytems for production. We want simple HA solution.

I have planned as below.. Pls. correct me if I am wrong..

1. On one node ( Node -A) - I will choose HA Installation from "sapisnt" , it will install ASCS ( standalone enque and message server), I will configure Enque Replication Server (ERS)

2. Dialog instance on other node (Node - B) -

3. IBM HA will sit on Node - A

4. OS guys will help in maping the failover clusters..

Is my understading is correct ?..

Nick

    Hi Nick,

    As per my knowledge for HA you can plan as follows:

    Assuming at least two nodes for HA.

    on first node install

    ASCS and SCS

    then Install DB on second node

    then Install CI on first node

    If you want you can install dialog instance in additional application server other than this two nodes

    As per your requiremnts you can install as much as Dialog instance.

    Regards,

    Nitin Salunkhe.

      Hi Nitin,

      I have completed HA installtion on 1st Node.

      Now, I started DI installtion on the second node. I am struck up with this. Afte giving profile path /sapmnt/P01/profile ( it is NFS mounted) _. It is asking for password for the P01adm I supplied P01adm password. ( P01adm is node 1 user)

      In ABAP Schema I have maintained standard SAPSR3.

      In the mid of the installtion, it says can't create P01adm. it is already exist. It is not allowing me to create an user "P02adm" ( for the second node).

      Pls. give me your valuable suggestion.

      Thanks

      Nick
