The IMS Universal drivers: CICS connections

Java™ applications that run on IBM® CICS® Transaction Server for z/OS® can access IMS databases by using the type-2 connectivity provided by the IMS Universal drivers. Other than the Java layer, access to IMS from a Java application is the same as for a non-Java application.

Note: Type-2 connectivity support will be delivered through the IMS service process.

CICS supports the following IMS Universal drivers:

  • IMS Universal JDBC driver
  • IMS Universal DL/I driver

The following figure shows a JCICS application that is accessing an IMS database by using the IMS database resource adapter (DRA) interface and the type-2 connectivity of an IMS Universal driver.

Figure 1. CICS application using a type-2 IMS Universal driver
Begin figure description. The Java application, running on CICS, uses the type-2IMS Universal driver and DRA layers to access DL/I on IMS DB. End figure description.
