DB2 Application Data Recovery

Case Training
Bristol, Edinburgh, Leeds, London, United Kingdom

Course Format: Classroom | E-learning | Virtual Class | Online | On-site | Blended | Self-paced

Course Description:

'' This course is aimed at Developers and Database Administrators who need to be able to back-up and recover DB2 data and understand Application COMMIT, ROLLBACK and restart design issues.

Pre-requisites
Delegates attending this course must already have a working DB2 knowledge, either in the role of a DBA or as a DB2 Applications Programmer. This experience can be gained by attending courses DB01 or DB05.

Course Objectives
The aim of this course is to provide the programmer, with the necessary skills required to backup and recover DB2 data. The course also covers design issues relating to Application Program restart and recovery. On completion of this course the student will be able to:

describe the DB2 objects that may be copied and recovered
understand and run the COPY Utility
understand and run the RECOVER Utility
understand and run the QUIESCE Utility
understand and run the COPYTOCOPY Utility
understand and run the MERGECOPY Utility
describe the recovery implications where RI is used
understand and run the CHECK DATA Utility
design Application Programs with restart capability
use Utility Lists and Dynamic Allocation
Course Environment
Development will be performed using:

IBM Mainframe
