• What is the cause and solution for SAP error message DB6PM344 - Database connection &1 is still in use by NLS connection &2 ?

  The SAP error message DB6PM344 indicates that a database connection is still in use by a Non-Local System (NLS) connection. This typically occurs in environments where multiple database connections are managed, and it suggests that a particular database connection cannot be released or terminated because it is still being utilized by another process or connection.
  Cause:
  
  Active Connections: The database connection is actively being used by an NLS connection, which means that there are ongoing transactions or operations that have not yet completed.
  Resource Locking: There may be locks on the database resources that prevent the connection from being released.
  Configuration Issues: Misconfiguration in the database or SAP system settings can lead to improper handling of connections.
  Long-Running Queries: If there are long-running queries or transactions, they may hold onto the connection longer than expected.
  
  Solution:
  
  Identify Active Connections: Use database management tools or SQL queries to identify which NLS connection is using the database connection. This can help you understand what processes are still active.
  Terminate Unused Connections: If you find that there are connections that are no longer needed, you can terminate them safely. Ensure that you do not disrupt any critical processes.
  Check for Locks: Investigate if there are any locks on the database that are preventing the connection from being released. You may need to resolve these locks.
  Review Configuration: Check the configuration settings for both the SAP system and the database to ensure that they are set up correctly for handling connections.
  Optimize Queries: If long-running queries are the issue, consider optimizing them to reduce their execution time and free up connections more quickly.
  Restart Services: In some cases, restarting the database or the SAP application server may help clear up any lingering connections.
