IMS Universal drivers: WebSphere Application Server for z/OS type-2 connections
When WebSphere Application Server for z/OS and IMS are on the same logical partition (LPAR), Java™ applications running in WebSphere Application Server for z/OS can access IMS databases by using the type-2 connectivity provided by the IMS Universal Database resource adapters.
The type-2 connectivity of the IMS Universal Database resource adapters provides local, non-TCP/IP access to IMS databases.
To deploy an application that uses the type-2 connectivity, you must install one of the IMS Universal Database resource adapters in WebSphere Application Server for z/OS and configure the IMS Open Database Access (ODBA) interface.
IMS Universal Database resource adapter type-2 connectivity supports both bean-managed bean methods and container-managed bean methods. Optionally, transaction applications can be managed by the z/OS Resource Recovery Services local option.
The following figure shows an EJB application that is accessing IMS data. The database requests are passed to a type-2 IMS Universal Database resource adapter, which converts the requests to DL/I calls. The IMS Universal Database resource adapter passes these calls to ODBA, which uses the IMS database resource adapter (DRA) interface to access the DL/I region in IMS.
