The guidelines for configuring SAP WebAS for high availability are as follows:

• In a service group, keep the single point of failure as minimal as possible and watch the application startup time.

• Assign a virtual hostname to the component within the switchover environment. Since the physical hostname changes with the switchover, this is a must have requirement.

• Based on the expected failover time configure the reconnection parameters for all software components and enable its automatic reconnection.

• Configure sapcpe to copy the instance specific executables and binaries from a central file system to the instance executable directory, during the instance startup.
