Server Functions
Use
The server functions are used to deactivate or close down SAP servers without jeopardizing the requests the server is currently processing. They enable the server to complete all the requests it is currently processing without accepting any new requests.
Integration
These functions allow the state of an SAP server to be changed. The possible server states are described under
SAP Application Server States.Prerequisites
The functions in question are system administration functions that may only be used when a valid username and password are given.
Features
The following functions can be used on the selected servers.
Hard-terminate server
A hard termination is equivalent to a signal 2 on the operating system level. The dispatcher and all its work processes are terminated; requests in the queue are ignored; and requests that are currently being processed are terminated.
Soft-terminate server
This function is new in SAP Web Application Server 6.10. All services that the application server provides (updates, batch, and so on) are no longer available, but all requests that are still in the queue are completed by the work processes. Once all requests are completed, the application server terminates.
The server state is then
shutdown.The activate function can no longer be used to activate the server.
Close connection
In this case, the connection between the selected server and the message server is terminated. No more requests from other application servers can reach the server.
This function tests the connection to the message server, because normally the connection has to be re-established.
Deactivate
This has the same effect as soft terminate, except that the server does not shut down when it has finished processing all requests. Instead, it enters the
passive state and can be re-started at any time by means of the activate function.Activate
This is used to re-activate servers in the
passive state. The state then returns to active.Activities
