• What is the cause and solution for SAP error message GW068 - Socket option keep-alive has been activated for remote gateway(s) ?

  The SAP error message GW068 indicates that the socket option "keep-alive" has been activated for remote gateways. This message typically arises in the context of SAP Gateway communication, where the keep-alive option is used to maintain a persistent connection between the client and server.
  Cause:
  The error message GW068 is generally caused by the following factors:
  
  
  Network Configuration: The keep-alive option is enabled in the network configuration, which can lead to issues if the network is unstable or if there are firewalls or routers that drop idle connections.
  
  
  Timeout Settings: If the timeout settings on the server or client side are not aligned, it can lead to premature disconnections, triggering the keep-alive mechanism.
  
  
  Resource Constraints: If the server is under heavy load or if there are resource constraints, it may not be able to handle keep-alive packets effectively.
  
  
  Gateway Configuration: The SAP Gateway configuration may have been altered, leading to the activation of the keep-alive option.
  
  
  Solution:
  To resolve the GW068 error, you can consider the following solutions:
  
  
  Check Network Stability: Ensure that the network connection between the SAP system and the remote gateway is stable. Look for any intermittent connectivity issues.
  
  
  Adjust Timeout Settings: Review and adjust the timeout settings on both the client and server sides to ensure they are compatible. This may involve increasing the timeout values to prevent premature disconnections.
  
  
  Review Gateway Configuration: Check the configuration of the SAP Gateway. You may need to disable the keep-alive option if it is not necessary for your use case. This can typically be done in the SAP Gateway settings.
  
  
  Monitor Resource Usage: Monitor the server's resource usage (CPU, memory, etc.) to ensure it is not overloaded. If necessary, optimize the server performance or scale resources.
  
  
  Firewall and Router Settings: If there are firewalls or routers in the network path, check their settings to ensure they are not configured to drop idle connections too aggressively.
  
  
  SAP Notes: Check for any relevant SAP Notes or updates that may address this issue. SAP frequently releases patches and updates that can resolve known issues.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for more details on configuring the SAP Gateway and understanding socket options.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
