  2. DB2 for LUW: Administration in Linux/UNIX/Windows Environments


    The course is designed for those applications programmers, designers, analysts and DBAs responsible for developing and maintaining an efficient Db2 LUW environment. The presentation combines formal classroom tuition with hands-on, practical workshop sessions, which will introduce all aspects of relational technology as implemented by Db2 for Linux, UNIX or MS Windows.


    Delegates will learn how to

    • use Command Center or other SQL execution environments (e.g. WinSQL) to code SQL statements
    • use the System Catalog
    • describe and control the locking strategy used by Db2 to maintain data integrity
    • list the different development environments available
    • explain the use and implementation of Stored Procedures and UDFs using the Development Center
    • list the different types of indexes and the use of Index Advisor
    • use Visual Explain
    • use and understand the Health Center
    • describe the development and execution of Utilities
    • explain the use of Journals
    • describe the Replication Center
    • explain the use of the Task Center
    • describe the use the Event Analyzer
    • explain the Indoubt Transaction Manager
    • use the Memory Visualizer
    • describe the Configuration Assistant.



    All those who are exposed to, or are required to write and perform activities associated with application development and implementation, in a Db2 for Linux, UNIX, AIX or Windows environment.
