• What is the cause and solution for SAP error message DB6PM408 - No history data available as WLM event monitors haven't yet been created ?

  The SAP error message DB6PM408 indicates that there is no history data available because Workload Management (WLM) event monitors have not yet been created. This typically occurs in the context of SAP systems that utilize a database management system (DBMS) with workload management capabilities, such as IBM Db2.
  Cause:
  The error arises when you attempt to access historical performance data or workload statistics, but the necessary WLM event monitors have not been set up. WLM event monitors are essential for tracking and recording workload performance metrics over time. Without these monitors, the system cannot collect or store historical data, leading to the error message.
  Solution:
  To resolve this issue, you need to create the necessary WLM event monitors. Here are the steps to do so:
  
  
  Access the Database Management System: Log in to your database management system (e.g., IBM Db2).
  
  
  Create WLM Event Monitors:
  
  Use the appropriate SQL commands or database management tools to create the WLM event monitors. The specific commands may vary depending on the version of the database you are using.
  For example, in Db2, you can create an event monitor using the following SQL command:
  CREATE EVENT MONITOR <monitor_name> FOR WLM
  
  Replace <monitor_name> with a suitable name for your event monitor.
  
  
  
  Configure the Event Monitors: Ensure that the event monitors are configured correctly to capture the desired metrics. You may need to specify options such as the data collection interval and the types of events to monitor.
  
  
  Start the Event Monitors: After creating the event monitors, make sure they are started and running. You can check their status using the appropriate commands or tools.
  
  
  Wait for Data Collection: Once the event monitors are active, they will begin collecting data. However, it may take some time before historical data is available, as the monitors need to gather information over a period.
  
  
  Check for Errors: After setting up the event monitors, monitor the system for any errors or issues that may arise during data collection.
  
  
  Related Information:
  
  Documentation: Refer to the official documentation for your specific database management system for detailed instructions on creating and managing WLM event monitors.
  Performance Monitoring: Familiarize yourself with performance monitoring best practices to ensure that you are capturing the right metrics and that your system is optimized for workload management.
  SAP Notes: Check SAP Notes and Knowledge Base Articles for any specific guidance or updates related to this error message and WLM configuration.
  
  By following these steps, you should be able to resolve the DB6PM408 error and start collecting historical data for your SAP system's performance monitoring needs.
