Use the SAP Listeners screen to add or edit listeners.
You can also display the following screens from this screen:
Program ID
The Program ID that you specified when creating the corresponding RFC destination
on the SAP server. This field is case-sensitive.
Gateway Host
The application server host on which SAP BC registers.
Note: It is important to use the same gateway host as with the RFC destination in the SAP system.
Gateway Service
This corresponds to your SAP system number. If your SAP system number is
"01" then your gateway service is "sapgw01."
Threads
The number of simultaneous incoming RFCs handled by this Listener. The
information is given as a group of two paired numbers: (currentBusy)/(peakBusy)
(currentActive)/(maxThreads)
currentBusy
Number of threads that are currently used by an application.peakBusy
Maximum number of threads used simultaneously by applications.currentActive
Number of threads that are currently active, i.e. that could accept a request if they are not busy. If there are inactive threads, they will be restarted by the Listener restarter.maxThreads
Number of threads as configured. This is the maximum number of active threads for this Listener.
Started?
Specifies the status of your listener: started (green ball) or stopped
(red ball). By clicking on the ball the Listener can be stopped/started.
State
This field shows the current state of the Listener. There are five possible
states:
State |
Description |
---|---|
|
|
Stopped (red ball) |
The Listener is stopped and cannot accept requests. |
Started (blue ball) |
First state after starting a Listener. As soon as a thread is active the state switches to alive. |
Alive (green ball) |
There is at least one active thread for that
Listener. |
StartupError (yellow ball) |
If a startup error occurs the listener will be in this state. It's possible to click on the yellow ball to get details about the error. When clicking a second time the state will switch to either dead or alive depending on the number of active threads. |
Dead (red ball) |
The listener is started, but all threads are inactive. As a consequence, the listener cannot accept requests. |
Delete
Click the Delete symbol
to remove the selected listener.
