Viewing Parameter Values

GaussDB uses a set of default running parameters after it is installed. You can modify the parameters to better fit your application scenarios and data volume.

Procedure

  1. Connect to a database. For details, see Connecting to a Database.
  2. View the parameter values in the database.

    • Method 1: Run the SHOW command.
      • Run the following command to view the value of a certain parameter: 
        1
        		 
        openGauss=# SHOW server_version;

        server_version indicates the database version.

      • Run the following command to view values of all parameters: 
        1
        		 
        openGauss=# SHOW ALL;
    • Method 2: Query the pg_settings view.
      • Run the following command to view the value of a certain parameter: 
        1
        		 
        openGauss=# SELECT * FROM pg_settings WHERE NAME='server_version';
      • Run the following command to view values of all parameters: 
        1
