SAP PI 7.1 High Availability, Active-Active or Active-Passive

[Former Member]

We are planning go to HA system for PI 7.11

I've few doubts/questions regarding this.

Can we make Active-Active clustering or Active-Passive? Or itu2019s our choice?

If it is our choice, then is at Configuration level (Application level)? or hardware level?

What are additional steps we need to take for Active-Active clustering? (Which we are looking for)

What is recommended by SAP?

Any Pros & Cons.

Please reply me if you have any information regarding this, any information regards to this is greatly appreciated

Thanks

Sagar

Hi Sagar,

Please use Active-Passive for your SAP PI 7.1 High Availability system.

For more details, please refer to the sdn link:

->High Availability FAQ

->What is an "active-active cluster"?

An active-active cluster consists of two independent server nodes at a minimum. The workload within a cluster resource is shared between the server nodes. If a cluster node crashes the processes are resumed by the remaining cluster nodes. An active-active cluster configuration means that a cluster resource is active on all cluster nodes. The aim of an active-active cluster is not only to provide high availability system but to distribute the workload between the cluster nodes. Applications with a very high workload like databases benefit from an active-active setup. Due to the SAP Central Services Instance is a light component an active-active setup does not make any sense. Therefore the SCS is implemented as an active-passive cluster resource.

Hi ,

If there is requirement of ACTIVE ACTIVE clustering , then you can achive by creating sperate Zones on OS level.

1. will be for DB and CS

2. will be for CI.

There no concept of SAP recommendation , If there is a customer requirement , they can configure.

You will get detail of Active active clusturing information on Installtion Guide in HIGH AVAILABILITY section.
