IBM DB2 for Linux, UNIX, and Windows Performance Tu ning and Monitoring Workshop

Duración: 4 Días Código del Curso: CL412G

Temario:

This course enables you to learn how to tune for optimum performance the IBM DB2 9 for Linux, UNIX, and Windows relational databasemanagement system and associated applications written for this environment. You will also learn about DB2 9 for Linux, UNIX, and Windows ina single partition database environment. Explore performance issues affecting the design of the database and applications using the database,the major database performance parameters, and the different tools that assist in performance monitoring and tuning.In this course, you will also use tools that are common across the Linux, UNIX, and Windows environments. During labs running on DB2 9.7,you will enhance your ability to use monitoring tools, explain tools and DB2 utilities like RUNSTATS, REORG and db2batch to tune a databaserunning on your local LINUX workstation.

Dirigido a:

This is an advanced course for database designers, database administrators, and application developers working with DB2 for Linux, UNIX,and Windows who are concerned about performance.This course is appropriate for students using DB2 in a z/Linux environment.

Objetivos:

Define the impact of database design (tables, indexes, and dataplacement) on database performance

Tune parameters to achieve optimum performance

Describe database application programming considerations andhow they affect performance Identify and use the tools that assist in monitoring and tuning of a

database

Identify and describe the parameters (database andnon-database) that affect performance

Prerequisitos:

You should complete:

DB2 9 Database Administration Workshop for Linux, UNIX, andWindows (CL2X2) orDB2 9 for Linux, UNIX, and Windows Quickstart for ExperiencedRelational DBAs (CL482)or have equivalent experience
