• What is the cause and solution for SAP error message Q2029 - DB parameter &1 successfully changed - change is not permanent ?

  The SAP error message Q2029 indicates that a database parameter has been successfully changed, but the change is not permanent. This typically means that the parameter was modified in the current session or instance of the database, but the change will not persist after the database is restarted.
  Cause:
  
  Dynamic Change: The parameter was changed dynamically, meaning it was altered while the database was running. Such changes are often temporary and will revert to their original values upon a restart.
  Configuration: The parameter may not have been set in the database configuration files (like init.ora for Oracle or postgresql.conf for PostgreSQL), which means that the change will not be saved permanently.
  User Permissions: The user may not have the necessary permissions to make permanent changes to the database configuration.
  
  Solution:
  
  
  Make Permanent Changes:
  
  Identify the parameter that was changed and locate the appropriate configuration file for your database.
  Edit the configuration file to include the new value for the parameter.
  Save the changes and restart the database for the changes to take effect permanently.
  
  
  
  Use Database Management Tools:
  
  If you are using a database management tool or interface, look for options to make changes permanent or to save the configuration.
  
  
  
  Check User Permissions:
  
  Ensure that the user account making the changes has the necessary permissions to modify the database configuration files.
  
  
  
  Consult Documentation:
  
  Refer to the specific database documentation for instructions on how to change parameters permanently, as the process may vary depending on the database system (e.g., Oracle, SQL Server, PostgreSQL).
