UD04 - DB2 LUW Transition for existing DBAs - 3 Days

Course Description

This training course is aimed at Database Administrators, already familiar with Database Administration on other platforms, who require an in-depth knowledge of the key tasks normally performed by a DB2 for LUW DBA.


An existing knowledge of Database Administration is expected (e.g. in z/OS, Oracle etc).

  • use the DB2 Toolset
  • define / maintain DB2 objects using DDL statements CREATE, ALTER and DROP
  • define partitioning databases and tables
  • use IBM Data Studio and the Data Studio Web Console
  • run IMPORT, EXPORT and LOAD statements
  • use High Availability Disaster Recovery (HADR)
  • define Referential Integrity constraints and Table Check constraints
  • resolve integrity violations
  • understand the application development process
  • bind plans and packages
  • set up database security
  • understand and resolve locking issues
  • monitor database activity
  • investigate system, application and SQL performance issues
  • perform database replication tasks


The aim of this course is to cross train a Database Administrator with the necessary skills required to function as a DB2 DBA within a LUW environment.

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


The course applies to DB2 (up to v12) running in a Linux, Unix or Windows environment.


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.
