• What is the cause and solution for SAP error message /SDF/DB6019 - The DLCHKTIME parameter value should be lower than LOCKTIMEOUT ?

  The SAP error message /SDF/DB6019 indicates that there is a configuration issue related to the database locking parameters in your SAP system. Specifically, the error states that the DLCHKTIME parameter value should be lower than the LOCKTIMEOUT parameter value. 
  Cause:
  
  Parameter Misconfiguration: The DLCHKTIME parameter defines the time interval for checking deadlocks, while the LOCKTIMEOUT parameter specifies the maximum time a transaction will wait for a lock to be released. If DLCHKTIME is set to a value greater than or equal to LOCKTIMEOUT, it can lead to situations where the system may not handle deadlocks effectively, as it would check for deadlocks after the timeout has already occurred.
  
  Solution:
  To resolve this error, you need to adjust the values of the DLCHKTIME and LOCKTIMEOUT parameters in your SAP system configuration. Here are the steps to do this:
  
  
  Access the SAP System: Log in to your SAP system with appropriate administrative privileges.
  
  
  Transaction Code RZ10: Use transaction code RZ10 to change the profile parameters.
  
  
  Edit Profile Parameters:
  
  Find the profile that is currently active (usually the instance profile).
  Look for the parameters DLCHKTIME and LOCKTIMEOUT.
  Ensure that the value of DLCHKTIME is set to a value lower than LOCKTIMEOUT. For example, if LOCKTIMEOUT is set to 10 seconds, DLCHKTIME should be set to a value less than 10 seconds (e.g., 5 seconds).
  
  
  
  Save Changes: After making the necessary changes, save the profile.
  
  
  Restart the Instance: For the changes to take effect, you may need to restart the SAP instance.
  
  
  Related Information:
  
  
  Parameter Definitions:
  
  DLCHKTIME: This parameter defines the time interval (in seconds) for checking deadlocks in the database.
  LOCKTIMEOUT: This parameter defines the maximum time (in seconds) that a transaction will wait for a lock to be released before timing out.
  
  
  
  Best Practices: It is generally recommended to set DLCHKTIME to a value that is significantly lower than LOCKTIMEOUT to ensure that deadlocks are detected and handled promptly.
  
  
  Monitoring: After making changes, monitor the system for any further locking issues or deadlocks to ensure that the adjustments have resolved the problem.
  
  
  Documentation: Always refer to the official SAP documentation or consult with your SAP Basis team for specific recommendations based on your system's configuration and workload.
  
  
  By following these steps, you should be able to resolve the error message /SDF/DB6019 and ensure that your SAP system handles locking and deadlocks appropriately.
