21 Chapter 21. IMS Remote Database Services IBM IMS provides the capability to allow Java programs to access IMS resources. In this chapter, we focus on IMS Java Remote Database Services (RDS), which is introduced on IMS Version 9. With IMS RDS, you can develop and deploy applications that run on WebSphere Application Server on non-z/OS platforms and access IMS databases remotely through an IBM-provided EJB on WebSphere Application Server for z/OS. In this chapter, we provide the information about the infrastructure of IMS RDS, how to work with the DL/I model utility, considerations about making SQL calls, and the step-by-step procedure for creating the Web application to access the IMS database through IMS RDS.
