Audience

    This intermediate course is for System administrators, database administrators, and technical personnel involved in planning, implementing, and maintaining DB2 databases.

This course is appropriate for students using DB2 in a z/Linux environment.

Prerequisites

You should be able to:

    Use basic OS functions such as utilities, file permissions, hierarchical file system, commands, and editor

    State the functions of the Structured Query Language (SQL), and be able to construct DDL, DML, and authorization statements

    Windows Operating System Training

    Linux Operating System Training

    AIX Operating System Training

    or have equivalent administration experience

    SQL and relational database basics

    DB2 SQL Workshop (CE12), (3E12)

    or have equivalent knowledge of SQL basics

Skills taught

    Administer a DB2 database system using commands and GUI tools

    Manage System Managed Storage (SMS) and Database Managed Storage (DMS) databases and apply data placement principles

    Implement a given logical database design using DB2 to support integrity and concurrency requirements

    List and describe the components of DB2

    Define a DB2 recovery strategy and perform the tasks necessary to support the strategy
