• What is the cause and solution for SAP error message S_ORA_MON002 - Please increase oracle parameter "parallel_min_servers" (see note 716000) ?

  The SAP error message S_ORA_MON002 indicates that the Oracle database is unable to allocate the required number of parallel servers for a query or operation because the parallel_min_servers parameter is set too low. This can occur when a query is executed that requires parallel processing, but the database configuration does not allow for enough parallel server processes to be allocated.
  Cause:
  The error is caused by the parallel_min_servers parameter being set to a value that is insufficient for the workload being executed. This parameter defines the minimum number of parallel server processes that Oracle will allocate for parallel execution. If the workload demands more parallel processes than are available, this error will occur.
  Solution:
  To resolve this error, you need to increase the value of the parallel_min_servers parameter in your Oracle database configuration. Here are the steps to do this:
  
  
  Connect to the Oracle Database:
  Use a tool like SQL*Plus or any database management tool to connect to your Oracle database as a user with administrative privileges.
  
  
  Check the Current Value:
  You can check the current value of the parallel_min_servers parameter by executing the following SQL command:
  SHOW PARAMETER parallel_min_servers;
  
  
  Increase the Parameter Value:
  To increase the value, you can use the following command. Replace new_value with the desired number of minimum parallel servers:
  ALTER SYSTEM SET parallel_min_servers = new_value SCOPE=BOTH;
  
  SCOPE=BOTH means the change will take effect immediately and will also persist after a database restart. You can also use SCOPE=SPFILE if you want to make the change permanent but not immediate.
  
  
  
  Restart the Database (if necessary):
  If you set the parameter using SCOPE=SPFILE, you will need to restart the database for the changes to take effect.
  
  
  Monitor the Changes:
  After making the changes, monitor the performance and check if the error persists.
