Issue regarding JCo SAP Server out of Network

When you encounter network issues with your JCo SAP Server, you need to properly clean up resources and references before stopping the server instance. This prevents memory leaks and ensures graceful shutdown of your SAP connectivity components.

Required Actions for JCo Server Cleanup

You need to perform the following actions when you are stopping the JCo server instance ?

• Delete server references: Remove all references of your server from the ServerDataEventListener instance. If you need to use the reference later, you can use the registered ServerDataProvider object to fetch the reference of the ServerDataEventListener instance.
• Delete destination references: Remove all references of your destination from the DestinationDataEventListener instance. If you need to use the reference later, you can use the registered DestinationDataProvider object to fetch the DestinationDataEventListener instance.

Example Implementation

Here's how to properly clean up JCo server resources ?

// Clean up server references
if (serverDataProvider != null) {
    ServerDataEventListener serverListener = serverDataProvider.getServerDataEventListener();
    if (serverListener != null) {
        serverListener.deleted("YOUR_SERVER_NAME");
    }
    serverDataProvider = null;
}

// Clean up destination references  
if (destinationDataProvider != null) {
    DestinationDataEventListener destListener = destinationDataProvider.getDestinationDataEventListener();
    if (destListener != null) {
        destListener.deleted("YOUR_DESTINATION_NAME");
    }
    destinationDataProvider = null;
}

// Stop the JCo server
JCoServer server = JCoServerFactory.getServer("YOUR_SERVER_NAME");
if (server != null) {
    server.stop();
}

Conclusion

Proper cleanup of ServerDataEventListener and DestinationDataEventListener references is essential when handling JCo SAP Server network issues. This ensures resources are freed correctly and prevents connectivity problems during server restarts.
