3.7.1 Overview of connections using DB Connector for Cosminexus RM and Cosminexus RM

DB Connector for Cosminexus RM is a resource adapter that is integrated with Cosminexus RM and uses the JMS interface to connect to a database.

By integrating with Cosminexus RM, you can use the JMS interface to access the database queue from the servlets, JSPs, and Enterprise Beans (Session Beans, Entity Beans, and Message-driven Beans). You can also use the JDBC interface to access the database tables.

When you use the JMS interface and JDBC interface to access the same database, you can process the global transaction using a single-phase commit. Due to this, the processing performance improves. Also, the JMS interface and JDBC interface can share the physical connection used for the database connection, so the resources can be utilized effectively.

The following figure gives an overview of connections using DB Connector for Cosminexus RM and Cosminexus RM.
