Managing Serviceguard Extension for SAP Version B.05.10, December 2012

3 SGeSAP Cluster Administration

SGeSAP clusters follow characteristic hardware and software setups. An SAP application is no

longer treated as though it runs on a dedicated host. It is wrapped up inside one or more

Serviceguard packages and packages can be moved to any of the hosts that are inside of the

Serviceguard cluster. The Serviceguard packages provide a virtualization layer that keeps the

application independent of specific server hardware. The virtualization is transparent in many

aspects, but in some areas special considerations apply. This affects the way a system gets

administered. Topics presented in this chapter include:

• Performing standard tasks in System Management Homepage

• Performing standard tasks with SAP's startup framework

• Change Management

• Mixed clusters

on the right hand side of a page, move your cursor over a package icon to display the package

information pop-up window. Each SGeSAP toolkit package is identified as such in the package

pop-up information under the Toolkits heading. In the Table view, the toolkit is listed in the Type

column of the Package Status table.
