and configured to autostart the SAP instance, SGeSAP will monitor the operation to make sure that
the instance startup succeeds.
1. In most situations, Serviceguard Manager Auto-Discovery can discover the SAP instances in
the cluster. If Serviceguard Manager can discover the SAP instances, you can either select an
SAP instance from the drop-down list, or enter one manually. If Serviceguard Manager cannot
auto-discover SAP instances in the cluster, the Select or Enter SAP Instance feature will not
appear. Instead, a field labeled, SAP instance is shown—you must enter an SAP instance
name into the SAP instance field.
2. The left side of the screen shows a list of SAP instances that are to be configured in the package.
To remove an SAP instance from this list, click Remove.
To edit a configured SAP instance, click on the radio button adjacent to the SAP instance you want
to edit, and click Edit>> — the instance information will move to the SAP Instance, Virtual Hostname,
and Replicated Instance input fields, where you can make changes. Click Update and the edited
SAP instance information will be returned to the Configured SAP Instances list.
To add an SAP instance to the Configured SAP Instances list, enter information into the SAP Instance,
Virtual Hostname, and Replicated Instance input fields, and then click <<Add to move this information
to the Configured SAP Instances list.
To clear the input fields, click Reset Input Fields.

A SAP Instance defines any SAP Netweaver Application Server instance based on the SAP ABAP
technology-stack, the SAP JAVA technology-stack or a combination of both. All parts of the instance
are packaged together as a single entity. This includes instance parts like icman, workprocesses,
SAP JVMs or an IGS. System Central Service instances or the corresponding Enqueue Replication
Service instances can also be specified. SAP instances are defined by specifying the instance name
and instance number.
