DATES:

1. CICS TS Overview
   • Examine the concepts and terminology of CICS Transaction Server and web support programming.
   • Understand the ways in which a web browser can be connected to a web server.
   • A web browser can be connected on a machine outboard to the CICS host and then connected to the CICS host.
   • A web browser can be connected directly to a CICS region on a z/OS host.
   • A web browser can be connected to a z/OS webserver, which in turn can connect to a designated CICS region on that z/OS image.
2. RDO - CEDA Changes
   • Use CEDA to manipulate CICS web resources.
   • Enable web support.
3. Application Programming Interface
   • Enable web browsers to invoke CICS applications using standard HTTP and IIOP protocols.
   • Code an Internet program which invokes a CICS application and passes data back to the web application.
4. Supplied Transaction Changes
   • Use CEMT transaction for extending support to the new resource types.
   • Redirect HTTP requests to another URL.
5. Databases and Files
   • Examine the access and updating of a database.
   • Code an application which maintains a table in a database.
   • Practice coding programs with commits and rollbacks.
6. Invoking CICS from the Web
   • Code and implement a web application.
   • Given a web data entry application, code a CICS program to retrieve, edit, and verify the data, and send back a response.
7. CICS Transaction Server Document
   • How to handle large documents.
   • Code a chunked response using a sequence of WEB SEND commands.
8. State Management
   • Save and retrieve state information.
   • Invoke state management sample programs, DFH$WBST and DFH$WBSR, as a transaction for saving data for retrieval later by the same transaction or by another transaction.
   • Recognize that state management and its associated token management, which were previously controlled by the terminal, will require additional techniques to save and retrieve data.
9. CICS and Java
   • Code a program using CICS-Java.
   • Invoke a Java procedure from a CICS application.
   • JCICS Classes
   • Examine JCICS, which is the Java class library for CICS.
   • Learn that JCICS supports most of the functions of the EXEC CICS API commands.
   • Create and demonstrate a Java class called Employee that calls a COBOL server program named EMPPGM.
10. JavaBeans
    • Code and use a JavaBean.
    • Use a JavaBean to perform specialized editing of the input data.
11. CICS Web Support
    • Develop a Java JCICS class which creates a simple web application.
    • Examine sample programs which access CICS resources.
    • Create TCP/IPSERVICE resource definitions for CICS web support.
