Learn how to write application programs that use Data Language One (DL/I) to process Information Management System (IMS) databases.

• 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

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.

You should complete:

• IMS Fundamentals (CM010) or IMS Fundamentals - Web - ILO(CMW01)

and a COBOL or PL/I language course, or be able to:

• List the basic components of the IMS database system
• Construct a non-DL/I application program in COBOL or PL/I

• DL/I Environment
• DL/I Call Processing
• DL/I Rtrieval Calls
• DL/I Update Calls
• DL/I Programming Techniques: Part 1
• DL/I Advanced Segment Search Arguments SSAs: Part 1
• DL/I Test Program
• DL/I Programming Techniques: Part 2
• DL/I Advanced Segment Search Arguments SSAs: Part 2
• System Service Calls
• Programming Standards
• High Availability Large Database (HALDB) Access

Prior to enrolling, IBM Employees must follow their Division/Department processes to obtain approval to attend this public training class. Failure to follow Division/Department approval processes may result in the IBM Employee being personally responsible for the class charges.

GBS practitioners that use the EViTA system for requesting external training should use that same process for this course. Go to the EViTA site to start this process:http://w3.ibm.com/services/gbs/evita/BCSVTEnrl.nsf

Once you enroll in a GTP class, you will receive a confirmation letter that should show:

• The current GTP list price
• The 20% discounted price available to IBMers. This is the price you will be invoiced for the class.
