- Configuring connectivity parameters for an external Pega Platform database
External database connections through a Java Database Connectivity (JDBC) URL are managed by Pega Platform and use connection pools to handle connection traffic. You can modify the default parameters of the connection pools to limit or increase connections, edit their timeout value, and create a new schema name for each database user to optimize connectivity for your external database connection. You can also request to add additional connectivity parameters specific to your external database vendor through My Support Portal.
