• What is the cause and solution for SAP error message RT091 - CCMS self-monitoring: Runtime of the SAPMSSY8 &1 &3 exceeds &2 &3 ?

  The SAP error message RT091 is related to the CCMS (Computing Center Management System) self-monitoring feature in SAP. This specific message indicates that the runtime of the SAPMSSY8 process (which is a background job) has exceeded a predefined threshold. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Long Running Job: The SAPMSSY8 job is taking longer to execute than expected. This could be due to various reasons such as:
  
  High system load or resource contention.
  Inefficient processing logic or queries within the job.
  Large volumes of data being processed.
  Database performance issues.
  
  
  
  Configuration Settings: The thresholds for acceptable runtimes may be set too low for the current workload or system performance capabilities.
  
  
  Solution:
  
  
  Analyze Job Performance:
  
  Check the job logs for SAPMSSY8 to identify any specific issues or bottlenecks.
  Use transaction codes like SM37 to monitor the job status and analyze its execution time.
  
  
  
  Optimize the Job:
  
  If the job is processing large volumes of data, consider optimizing the underlying logic or queries.
  Review any recent changes in the system that might have affected performance.
  
  
  
  Adjust Thresholds:
  
  If the job is expected to take longer due to increased data volume or processing requirements, consider adjusting the monitoring thresholds in the CCMS configuration.
  This can be done in transaction RZ20 or RZ21, where you can modify the alert thresholds for the job.
  
  
  
  System Performance Tuning:
  
  Check the overall system performance, including CPU, memory, and database performance.
  Consider performing database tuning or increasing system resources if necessary.
  
  
  
  Schedule Jobs Appropriately:
  
  If the job is running during peak hours, consider rescheduling it to a time when the system load is lower.
  
  
  
  Related Information:
  
  Monitoring Tools: Use tools like ST03N (Workload Analysis) and ST22 (Dump Analysis) to gather more insights into system performance and job execution.
  SAP Notes: Check for any relevant SAP Notes that might address known issues or provide additional guidance on optimizing the SAPMSSY8 job.
  Documentation: Review SAP documentation related to CCMS and background job management for best practices and configuration options.
  
  By following these steps, you should be able to identify the cause of the RT091 error and implement a solution to mitigate the issue.
