DB14 - DB2 z/OS for Assembler Developers - 5 Days

Course Description

This course provides the applications programmer with an in-depth knowledge of the DB2 development process. It is aimed at programmers who need to code or support DB2 application programs written in Assembler.

Pre-requisites

The delegate should be familiar with the z/OS host environment, together with a working knowledge of Assembler program development using TSO / ISPF.

Objectives

The aim of this course is to provide the programmer, unfamiliar with DB2, with the necessary skills required to define, access and manipulate DB2 data, either via an application program or using SPUFI.

On completion of this course the student will be able to:

  • set up a DB2 test environment, using correctly defined tables, views, indexes, synonyms and aliases
  • use both permanent and temporary tables
  • use the DB2I toolset, including SPUFI
  • code SQL statements to read and manipulate DB2 data
  • develop, prepare and execute DB2 programs
  • bind packages and plans
  • use non-scrollable and scrollable cursors
  • use multi-row INSERT and FETCH processing
  • describe the locking process used by DB2
  • define and use Referential Integrity
  • use Identity Columns and Sequences
  • produce EXPLAIN output using a PLAN_TABLE
  • use the LOAD utility to populate tables

Environment

Development will be performed using:

  • IBM Mainframe
  • DB2 for z/OS Versions 10, 111 or 12

Customisation

For on-site courses (i.e. at your premises), we are more than happy to tailor the course agenda to suit your exact requirements. In many cases, we are able to build your in-house standards and naming conventions into the delivered course.
