How to Register and Configure the Sun Cluster HA for SAP Web Application Server by Using `clsetup`

The procedures in this section describe the registration and configuration of the following components of the SAP Web Application Server by using clsetup utility.

SAP central services, which include these services:
- SAP enqueue server
- SAP replica server
- SAP message server

Note –

If you have already created the logical hosts for the SAP central services and SAP replica server resource groups, select those logical hosts when you run clsetup. The clsetup utility will then add SAP central services and SAP replica server resources to the existing resource groups containing these logical hosts.
