Smart SAP Assistant

• What is the cause and solution for SAP error message /SOMO/JOBMON156 - &2 parallel jobs were started. ?

  The SAP error message /SOMO/JOBMON156 &2 parallel jobs were started typically indicates that a certain limit on the number of parallel jobs that can be executed simultaneously has been reached or exceeded. This message is often related to background processing in SAP, particularly in the context of job scheduling and monitoring.
  Cause:
  
  Parallel Job Limit Exceeded: The system has a predefined limit on the number of parallel jobs that can be executed at the same time. If this limit is reached, any additional jobs that are attempted to be started will trigger this error message.
  Configuration Settings: The configuration settings for background processing may not be optimized for the current workload, leading to bottlenecks.
  Resource Constraints: The system may be experiencing resource constraints (CPU, memory, etc.) that prevent additional jobs from being processed.
  
  Solution:
  
  Check Job Configuration: Review the configuration settings for background jobs in transaction SM37 (Job Monitoring) or SM36 (Job Scheduling). Ensure that the maximum number of parallel jobs is set appropriately for your system's capacity.
  Adjust Parallel Processing Settings: You can adjust the settings for parallel processing in the SAP system. This can be done in transaction RZ10 (Profile Parameters) by modifying the parameter rdisp/wp_no_dia (for dialog work processes) and rdisp/wp_no_btc (for background work processes).
  Monitor and Optimize Jobs: Use transaction SM37 to monitor running jobs and identify any long-running or stuck jobs that may be consuming resources. Consider optimizing these jobs or rescheduling them to off-peak hours.
  Increase System Resources: If the system is consistently hitting the limit, consider increasing the hardware resources (CPU, memory) allocated to the SAP system.
  Review Job Scheduling: If you have a large number of jobs scheduled to run at the same time, consider staggering their execution times to avoid hitting the parallel job limit.
