• What is the cause and solution for SAP error message RT405 - CCMS self-monitoring: &1 alerts in cache invalidated ?

  The SAP error message RT405 indicates that there are alerts in the CCMS (Computing Center Management System) self-monitoring cache that have been invalidated. This typically occurs when the monitoring data has changed, and the cached alerts are no longer valid or relevant.
  Cause:
  
  Data Changes: The underlying data that the alerts are based on has changed, which can happen due to system updates, configuration changes, or other monitoring adjustments.
  Cache Invalidation: The CCMS uses caching to improve performance. When certain conditions are met (like changes in monitored parameters), the cache may be invalidated to ensure that the most current data is being used.
  System Performance: High system load or performance issues can also lead to cache invalidation as the system attempts to refresh its monitoring data.
  
  Solution:
  
  Refresh the Cache: You can manually refresh the CCMS cache to ensure that the latest monitoring data is being used. This can often be done through the SAP GUI or by using specific transaction codes related to CCMS.
  Check Monitoring Configuration: Review the configuration of your CCMS monitoring setup to ensure that it is correctly set up and that there are no misconfigurations that could lead to frequent cache invalidation.
  System Performance Tuning: If the issue is related to system performance, consider tuning the system to handle the load better. This may involve optimizing database performance, adjusting system parameters, or increasing hardware resources.
  Review Alert Definitions: Check the definitions of the alerts that are being invalidated. Ensure that they are still relevant and correctly configured.
  Consult SAP Notes: Look for any relevant SAP Notes that may address this specific issue. SAP frequently updates its knowledge base with solutions for known issues.
