24.2.7 Controlling the Debug Level for an Instance

Change the default instance-wide Debug Level using the APEX_INSTANCE_ADMIN API

For example, to set the Debug Level to Application Trace (LEVEL6), execute a statement similar to the following as SYS or the database user who has been granted the APEX_ADMINISTRATOR_ROLE database role.

BEGIN
    APEX_INSTANCE_ADMIN.SET_PARAMETER(
        p_parameter => 'SYSTEM_DEBUG_LEVEL',
        p_value     => '6');
    COMMIT;
END;
