With SGeSAP Version 3.03 it is possible to configure an SAP
Application Server within a MC/ServiceGuard package. For example, Figure 1-3 “Adoptive Node as Application Server” illustrates that in a 2 node cluster it is
common to configure the adoptive node to run as an additional application
server.
Whenever a failover of the DBCI-package happens, this application server
package will be shut down to free up resources for the DBCI-package.
When the failed primary node is afterwards repaired the application
server package can be easily brought up on this repaired node. The
advantage is that the DBCI package can remain running on the former
adoptive node without additional downtime for the application.
An additional example for the need of this SAP Application
Server package is to protect dedicated batch servers against hardware
failures.
Refer to Chapter 2, page 79 to get detailed information on
how to configure Application Server Packages.
