CMDBID: 54949 | Course Code: CM17G | Duration: 3 Days
Overview>
Learn how to write application programs that use Data Language One (DL/I) to process Information Management System (IMS) databases.
Audience>
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 an process IMS databases.
Skills Gained>
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
