Viewing GUC Parameters

GaussDB(DWS) GUC parameters can control database system behaviors. You can check and adjust the GUC parameters based on your business scenario and data volume.

  • After a cluster is installed, you can check common database parameters on the GaussDB(DWS) management console.

  • You can also connect to a cluster and run SQL commands to check the GUC parameters.
    • Run the SHOW command.
      To view a certain parameter, run the following command: 
      1
      		 
      SHOW server_version;

      server_version indicates the database version.

      Run the following command to view all the parameters: 
      1
      		 
      SHOW ALL;
    • Use the pg_settings view.
      To view a certain parameter, run the following command: 
      1
      		 
      SELECT * FROM pg_settings WHERE NAME='server_version';
      Run the following command to view values of all parameters: 
      1
      		 
      SELECT * FROM pg_settings;
