• What is the cause and solution for SAP error message DB6PM287 - Database connection &1 already existing ?

  The SAP error message DB6PM287, which states "Database connection &1 already existing," typically indicates that there is an attempt to create a database connection that already exists in the system. This can occur in various scenarios, such as when configuring database connections in SAP or when trying to establish a connection to a database that is already active.
  Cause:
  
  Duplicate Connection Attempt: The most common cause is that there is already an active connection to the database with the same identifier (e.g., connection name).
  Configuration Issues: There may be misconfigurations in the database connection settings, leading to attempts to create a connection that is already defined.
  Session Persistence: If a previous session was not properly closed, it might still hold onto the connection, causing conflicts when trying to establish a new one.
  
  Solution:
  
  Check Existing Connections: Verify the list of existing database connections in the SAP system. You can do this through transaction codes like DBACOCKPIT or DB02 to see if the connection already exists.
  Remove or Rename: If the connection is indeed duplicated, you can either remove the existing connection or rename the new connection you are trying to create.
  Restart Services: If you suspect that a session is hanging, consider restarting the relevant SAP services or the database itself to clear any stale connections.
  Review Configuration: Go through the configuration settings for the database connections in the SAP system to ensure there are no errors or duplications.
  Check Logs: Look into the system logs (transaction SM21) for any additional error messages or warnings that might provide more context about the issue.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to database connections. You can search for specific notes using the SAP Support Portal.
