8 Chapter 8. Reference application In this section, we describe the reference application that we created for the use cases. The application source code is available as softcopy on the Internet from the IBM Redbooks web server. Point your web browser at this location: ftp://www.redbooks.ibm.com/redbooks/SG247868 The reference application is a scaled-down facsimile of a production application, and it includes the following components: Job control language (JCL) COBOL programs and copybooks IBM WebSphere MQ for z/OS DB2 tables CICS online programs Queued sequential access method (QSAM) and Virtual Storage Access Method (VSAM) files Most of the application is batch (JCL). We based the application design on our combined experiences. The domain is a health insurance model. Important: This application is not actually a production application. We use it in this book only for illustrative purposes. © Copyright IBM Corp. 2011. All rights reserved. 407
