• What is the cause and solution for SAP error message ARUN_RELEASE_CHECK026 - No parallel background task resources are available in system ?

  The SAP error message ARUN_RELEASE_CHECK026 indicates that there are no available parallel background task resources in the system. This typically occurs when the system has reached its limit for background processing tasks, which can happen due to various reasons such as high system load, configuration settings, or resource constraints.
  Causes:
  
  Max Background Jobs Reached: The system has reached the maximum number of background jobs that can be executed simultaneously.
  System Load: High system load or resource contention can lead to a situation where all available background processing resources are occupied.
  Configuration Settings: The configuration for background processing may be set too low, limiting the number of parallel jobs that can run.
  Job Scheduling: There may be a large number of jobs scheduled to run at the same time, leading to resource exhaustion.
  System Performance Issues: Underlying performance issues in the system can also contribute to this error.
  
  Solutions:
  
  
  Check Background Job Status:
  
  Use transaction SM37 to check the status of background jobs. Identify if there are any long-running or stuck jobs that can be canceled or rescheduled.
  
  
  
  Increase Background Job Limits:
  
  You can increase the number of parallel background jobs allowed in the system. This can be done by adjusting the profile parameters:
  
  rdisp/wp_no_btc: This parameter controls the number of background work processes. Increase this value if necessary.
  
  
  After making changes, restart the instance for the changes to take effect.
  
  
  
  Optimize Job Scheduling:
  
  Review the scheduling of background jobs to avoid peak times. Stagger job execution times to reduce contention for resources.
  
  
  
  Monitor System Performance:
  
  Use transaction ST03N or ST06 to monitor system performance and identify any bottlenecks. Address any performance issues that may be affecting background processing.
  
  
  
  Check for Resource Contention:
  
  Ensure that there are sufficient system resources (CPU, memory, etc.) available for background processing. If necessary, consider scaling up the hardware or optimizing resource usage.
  
  
  
  Review Job Priorities:
  
  Adjust the priorities of background jobs to ensure that critical jobs have the resources they need to run.
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SM37: Monitor background jobs.
  SM50: Monitor work processes.
  ST03N: Analyze workload and performance.
  ST06: Monitor system performance metrics.
  
  
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or patches related to background processing issues.
  
  
  Documentation: Refer to SAP documentation for detailed information on configuring background processing and managing job scheduling.
  
  
  By following these steps, you should be able to resolve the ARUN_RELEASE_CHECK026 error and ensure that your SAP system can handle background processing tasks effectively.
