  The SAP error message DB6PM823: No deadlocks have been recorded typically indicates that the database system has not detected any deadlocks during its operation. This message is not necessarily an error but rather an informational message that can be useful for monitoring and troubleshooting database performance.
  Cause:
  
  
  No Deadlocks Occurred: The primary cause of this message is simply that there have been no deadlocks in the database at the time of the check. Deadlocks occur when two or more transactions are waiting for each other to release locks, and this message indicates that the database has not encountered such a situation.
  
  
  Database Configuration: The database may be configured in a way that minimizes the chances of deadlocks occurring, such as using appropriate isolation levels or lock management strategies.
  
  
  Application Logic: The application logic may be designed to avoid deadlocks by ensuring that transactions acquire locks in a consistent order.
  
  
  Solution:
  Since this message indicates that no deadlocks have been recorded, there is typically no action required. However, if you are concerned about potential deadlocks or if you are experiencing performance issues, consider the following:
  
  
  Monitor Database Performance: Continue to monitor the database for any signs of performance issues or deadlocks. Use database monitoring tools to analyze transaction behavior.
  
  
  Review Application Logic: Ensure that the application logic is designed to minimize the risk of deadlocks. This can include:
  
  Acquiring locks in a consistent order.
  Keeping transactions short and efficient.
  Avoiding long-running transactions that hold locks for extended periods.
  
  
  
  Database Configuration: Review the database configuration settings related to locking and transaction management. Adjust settings if necessary to optimize performance.
  
  
  Consult Documentation: Refer to the SAP and database documentation for best practices on managing transactions and locks.
  
  
  Related Information:
  
  
  Deadlock Detection: Most modern databases have built-in mechanisms to detect and resolve deadlocks automatically. Understanding how your specific database handles deadlocks can provide insights into performance tuning.
  
  
  Transaction Isolation Levels: Different isolation levels can affect the likelihood of deadlocks. Familiarize yourself with how these levels work and choose the appropriate one for your application.
  
  
  SAP Notes and Community: Check SAP Notes and the SAP Community for any specific recommendations or updates related to this message or deadlock management in your version of SAP.
