IMS Universal drivers: configuring connections to IMS

The IMS Universal drivers include the following adapters and drivers:

• The IMS Universal Database resource adapters, which take advantage of Java™ Platform, Enterprise Edition (Java EE) services.
• The IMS Universal JDBC driver, which support SQL calls that directly access your IMS data.
• The IMS Universal DL/I driver, which provides calls that are similar to DL/I in a Java programming interface.

When running in a distributed environment on a server such as WebSphere Application Server for distributed platforms, or in a remote z/OS environments on a server such as WebSphere Application Server for z/OS, or in WebSphere Application Server Liberty, the IMS Universal drivers connect to IMS using a type-4 connection architecture, which supports TCP/IP communications and socket management.

When running locally on the same logical partition (LPAR) as IMS, the IMS Universal drivers connect to IMS by using a type-2 connection architecture, which supports direct communication with IMS through the IMS Open Database Access (ODBA) and IMS database resource adapter (DRA) interfaces.

WebSphere Application Server supports all of the IMS Universal drivers in both distributed and z/OS environments.
