Before you perform operations on instances, ensure that the general prerequisites are met.

When you prepare instances, you bind virtual host names of an instance or a set of instances to network interfaces, and you mount remote memory locations to the local file system. For SAP instances, you register and start the instance agents. For database instances, you attach the database instance to the host and start the database listener.

You bind virtual host names of an instance to network interfaces, you mount remote memory locations to the local file system, and then you start an instance.

You start an instance or a set of instances. When you start an SAP system, you start the logical database, one or more application server instances (ABAP and/or Java), central services (such as a message server and enqueue server), and optional components (such as TREX and liveCache).

You restart an instance or a set of instances for example, after a power failure.

You can stop an instance or a set of instances. When you stop an SAP system, you stop the logical database, one or more application server instances (ABAP and/or Java), central services (such as a message server and enqueue server), and optional components (such as TREX and liveCache).

You can stop an instance, unmount remote memory locations from the local file system, and unbind virtual host names from the network interfaces.

You unmount remote memory locations from the local file system and unbind virtual host names from the network interfaces. For SAP instances, you stop and deregister the instance agent. For database instances, your detach the database and stop the database listeners.

You relocate an instance or a set of instances from one host to another, either physically, or virtually in either direction. The operation retains the status of the instances. Not running instances are unprepared and prepared.

You relocate an instance or a set of instances from one host to another, either physically, or virtually in either direction. The operation retains the status of the instances. Running instances are stopped, unprepared, prepared, and started.

You switch the status of a set of instances to Not running status.

The graceful shutdown allows an ABAP application server instance to be stopped in the timeout specified and all logged users to be informed for shutdown.

You restart the Java instance of your SAP NetWeaver dual-stack (ABAP + Java) system in a single or in a mass operation.

You restart and reregister an instance agent without unmounting/mounting remote memory locations and without unbinding/binding the virtual host name in a single or in a mass operation.

You register and start an instance agent in a single or in a mass operation.

You perform operations on systems that have an SAP Solution Manager system assigned to them.

You perform operations on systems that have a Focused Run system assigned to them.
