How To Fix RSDBMAN015 - - Maximum parallelism set to default (&1)

SAP Error Message - Details

• Message type: E = Error

• Message class: RSDBMAN -

• Message number: 015

• Message text: - Maximum parallelism set to default (&1)

What causes this issue?

This message explains the execution of InfoProvider read access for the
analytic engine.
The maximum parallelism for execution was set to the default value. If a
different parallelism value is required, you can set the value
explicitly using the RSADMIN parameter QUERY_MAX_WP_DIAG.

• What is the cause and solution for SAP error message RSDBMAN015 - - Maximum parallelism set to default (&1) ?

  The SAP error message RSDBMAN015 - "Maximum parallelism set to default (&1)" typically occurs in the context of database operations, particularly when dealing with data extraction or loading processes in SAP BW (Business Warehouse) or other SAP systems that utilize database management.
  Cause:
  This error message indicates that the system has reached the maximum limit of parallel processes that can be executed for a particular operation. The value &1 represents the default maximum parallelism level that the system has set. This can happen due to various reasons, including:
  
  System Configuration: The system may have a default setting for maximum parallelism that is lower than what is required for the current operation.
  Resource Constraints: The database or application server may be under heavy load, leading to a restriction on the number of parallel processes that can be executed.
  Database Settings: The database configuration may limit the number of concurrent connections or processes.
  
  Solution:
  To resolve the RSDBMAN015 error, you can consider the following steps:
  
  
  Check System Settings:
  
  Review the settings for maximum parallelism in your SAP system. This can typically be found in the configuration settings for the database or the BW system.
  You may need to adjust the parameters related to parallel processing. This can often be done in transaction codes like RZ10 (for profile parameters) or RZ11 (for dynamic parameters).
  
  
  
  Increase Parallelism:
  
  If the default value is too low for your operations, consider increasing the maximum parallelism setting. This may involve changing the configuration in the database or SAP BW settings.
  
  
  
  Monitor System Load:
  
  Check the current load on the database and application servers. If the system is under heavy load, consider scheduling the operation during off-peak hours or optimizing the workload.
  
  
  
  Database Configuration:
  
  Review the database configuration settings to ensure that they allow for sufficient parallel connections. This may involve consulting your database administrator.
  
  
  
  Consult SAP Notes:
  
  Look for relevant SAP Notes that may provide additional guidance or patches related to this error message. SAP Notes can often provide specific solutions or workarounds.
  
  
  
  Testing:
  
  After making changes, test the operation again to see if the error persists. Monitor the system performance to ensure that the changes have had the desired effect.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for your specific version of SAP BW or the database you are using for detailed configuration instructions.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have implemented.
  Performance Tuning: Consider performance tuning for your SAP system to optimize resource usage and improve overall efficiency.
  
  By following these steps, you should be able to address the RSDBMAN015 error and improve the parallel processing capabilities of your SAP system.
