About this course

Course code TPDBI
Duration 2 Days

This course provides attendees with an effective introduction to the skills and knowledge required to implement a DB2 system. The planning, installation and setting up of a DB2 subsystem are discussed in detail, along with an overview of operational issues.<br>Regularly revised and updated, this course also provides valuable information regarding the migration to new releases.

Prerequisites

A general understanding of DB2 is required. In addition, familiarity with either CICS or IMS would also be of use. The course assumes knowledge and use of TSO and ISPF.

Delegates will learn how to

  • describe the planning considerations for installing, migrating, or updating a DB2 for z/OS system
  • list additional considerations when using distributed data facility or shared data
  • explain the installation process using the DSNTINS0 or DSNTINST CLIST, and the jobs it produces
  • define the additional considerations when migrating between DB2 releases
  • describe DB2 attachment installation, and implications with other non-DB2 systems
  • manage the general day to day operation of the DB2 system.

Installation & Migration Review

The major steps; loading DB2 libraries (the SMP process); msys for setup; DB2 Customization Center; the install CLISTs; invoking the install CLIST; install main panel; installation panels; the customised jobs.

Installation CLIST

Installation Jobs

The installation jobs; job DSNTIJMV - define DB2 to z/OS; job DSNTIJCA - define ICF catalog; jobs DSNTIJIN & DSNTIJID - define & initialise system data sets; job DSNTIJUZ - define initialisation parameters; optional jobs; job DSNTIJTC - tailor the DB2 catalog; jobs DSNTIJTM, DSNTIJSG - Defining DB2 Objects, etc.; job DSNTIJRX - REXX support (optional); jobs DSNTIJIC & DSNTEJxx - back-up and verification.

Connecting to DB2

DB2 connections (attachments); TSO attachment; job DSNTIJVC - build the CLIST library; make libraries available to TSO; connect DB2I panels to main panel; invoking TSO attachment; CICS attachment; Resource Control Table; DB2CONN using CEDA; DB2ENTRY using CEDA; DB2TRAN using CEDA; controlling CICS attachment; IMS attachment; IMS Subsystem Member (SSM); Subsystem Member relationships; Resource Translation Table (RTT); controlling IMS attachment.

Migration & Updating
