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.
NOTE:

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:

        
           SELECT * FROM pg_settings WHERE NAME='server_version';

Run the following command to view values of all parameters:

        
           SELECT * FROM pg_settings;
