This is an intermediate course for individuals who write programs in Common Business Oriented Language (COBOL), or Programming Language One (PL/I), or Assembler language using DL/I to navigate through and process IMS databases.
Delegates should be able to:
- Construct a non-DL/I application program in COBOL or PL/I.
- List the basic components of the IMS database system - this knowledge can be gained by attending the IMS Fundamentals - CM01G course.
This course teaches delegates to write application programs that use Data Language One (DL/I) to process Information Management System (IMS) databases.
Course objectives include:
- Describe the basic differences between files and IMS databases as they relate to application program coding and logic.
- Describe the terms and processing characteristics of IMS hierarchic data structures.
- Construct DL/I calls for either COBOL or PL/I language programs.
- Write, test and debug a batch application program that uses the DL/I call functions.
- Use the IMS Test Program to prototype application program calls, and to perform ad-hoc read and update access to an IMS database.
- Describe the applications and uses of other DL/I features.
- Program for recovery and restart using DL/I calls to establish synchronization points.
- Describe the functions provided by High Availability Large Database (HALDB), and any program differences when accessing a Full Function database or a HALDB.
