Course description: DB2 9 for Linux, UNIX and Windows Quickstart for Experienced Relational DBAs - Instructor-led online

ILO classes are closed to further enrollment 5 business days before the start of class so that we can ensure students will have their materials on time. Please enroll in the next offering if the class start date is less than 5 days from today.

This is an online course. Please do not make travel arrangements for this course.After you receive confirmation that you are enrolled, you will be sent further instructions to access audio, video and remote labs.

This course teaches you to perform basic and advanced database administrative tasks using DB2 9 for Linux, UNIX, and Windows. These tasks include creating and populating databases and implementing a logical design to support recovery requirements. The access strategies selected by the DB2 optimizer will be examined using the DB2 Explain tools. Various diagnostic methods will be presented, including using the db2diag.log file messages to direct your investigation of problems, as well as using the commands db2pd, INSPECT, and db2support and DB2 traces. Students will learn how to implement automatic archival for database logs and how to plan a redirected database restore to relocate either selected table spaces or an entire database. This course provides a quick start to DB2 database administration skills for experienced relational Database Administrators (DBA).

You will get practical experience in the basic and advanced database administrative tasks of a wide variety of DB2 LUW utilities and functions by performing a series of lab exercises on a Linux platform. The exercises build skills that can be applied to DB2 database servers on any Linux, UNIX or Windows environment.
