IMS Universal drivers: WebSphere Application Server type-4 connections

Java™ applications that run on WebSphere Application Server can access IMS databases by using the type-4 connectivity provided by the IMS Universal drivers. The type-4 connectivity of the IMS Universal drivers enables Java application programs to access IMS databases from a wide variety of distributed and mainframe environments, either in stand-alone mode or under an application server, with or without XA support for global transactions.

The following figure provides an overview of a configuration that uses the type-4 connectivity of an IMS Universal Database resource adapter to connect to IMS from WebSphere Application Server for distributed platforms.

Figure 1. A WebSphere Application Server EJB application using a type-4 IMS Universal Database resource adapter
Begin figure description. An EJB application, running on a non-z/OS platform in WebSphere Application Server, uses a type-4 IMS Universal Database resource adapter to access IMS DB through a TCP/IP connection, IMS Connect, and ODBM. End figure description.

The following procedures apply to both WebSphere Application Server for distributed platforms and WebSphere Application Server for z/OS®.
