20 Feb 2008 Traditional application developers can use IBM Rational® Developer for System z to significantly increase their productivity and efficiency when creating and maintaining traditional mainframe applications. This tutorial shows you how. You download and use example code in a variety of typical development scenarios. The examples include programs that use CICS, VSAM, and DB2 including syntax checking and compiling. You also see the configuration steps to perform either local or remote syntax checking of COBOL programs. The program and associated assets (such as copybooks) can be stored on either z/OS or the local workstation. Even though the configurations shown are for COBOL applications, PL/I programmers could follow this tutorial and then apply similar steps to their PL/I programs.
Objectives - Work with COBOL batch code and with CICS statements that access either VSAM or DB2.
- Work with COBOL/CICS/DB2 code on the local workstation.
- Work with COBOL/CICS code on z/OS.
- Check syntax of COBOL code on your local workstation.
- Compile COBOL code on your local workstation.
- Check syntax of COBOL code stored on z/OS.
- Compile COBOL code stored on z/OS.
Prerequisites
To get the most out of this tutorial, you should be comfortable with COBOL programming on z/OS and have some familiarity with Rational Developer for System z.
System requirements
On your workstation you need Rational Developer for System z Version 7.1 and IBM TXSeries for Multiplatforms Version 6.1 installed to work with the sample code. TXSeries is included in Rational Developer for System z V7.1.
Because you will need to connect and submit jobs for remote execution, you must also have the Rational Developer for System z components installed and configured on the mainframe. You need to have already defined on your workstation a remote system and you should be connected to that system. For detailed help in creating this connection, see the IBM Rational Developer for System z Version 7.1.1 information center. For the scenario that uses a local database, you will also need DB2 installed on your workstation and the database name SAMPLE created. This tutorial was tested with DB2 Version 8.2, but you could use a later version, if desired.
Duration
The four scenarios in this tutorial takes about one hour to complete after your system is configured to meet the system requirements.
