P6 enables you to access data from different P6 EPPM databases. When you configure P6 to support multiple database instances, the Login page displays a Database list that enables users to choose the database instance where they want to connect.
Through the Primavera P6 Administrator, you can configure the server for P6 to manage user access to specific databases by requiring a database parameter in the URL. The database parameter, which is the name of a database instance, connects to the P6 server URL and points to that specific database instance. When users access the URL you specify, the Database list does not display in the Login page and they have login access only to the database instance defined by the database parameter. If users attempt to access the login page URL without specifying the required database parameter, a message displays to indicate that the URL is invalid and directs them to the administrator of P6.
For example, the following URL would log a user in to the database instance named Sample:
http://serverIP:listenport/login?db=Sample
As the administrator, you can specify a keyword that bypasses the database parameter requirement, so that you can access all databases through the Login page database list.
Follow instructions for the database dropdown key in Configuring Application Settings in the Primavera P6 Administrator to require a database parameter for the URL and to set a keyword to bypass the database parameter requirement.
