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 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.

      Method 2 can only be used to check the GUC parameter values of CNs, while the GUC parameter values of DNs can be viewed through Method 1: by using the management console.

      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 values of all 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;
