IBM DB2 LUW Performance Tuning and Monitoring for S ingle and Multiple Partition DBs

Längd: 5 Days Kurskod: CL442G

Sammanfattning:

Learn how to tune for optimum performance the IBM DB2 9 for Linux, UNIX, and Windows relational database management system andassociated applications written for this environment. Learn about DB2 9 for Linux, UNIX, and Windows in support of single partition and multiplepartition (DPF) database environments. 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. Use tools that are common across the Linux, UNIX, and Windows environments. During labs running on DB2 9.7, develop your ability to usemonitoring tools, Explain tools and DB2 utilities like RUNSTATS, REORG and db2batch to tune a database running on your local LINUXworkstation. Course Materials The course materials cover DB2 9.7 for Linux, UNIX, and Windows. Hands-On Labs The twelve labs use the DB2 9.7 Linux, UNIX, and Windows tools and commands to monitor, configure and analyze performance. The labs areperformed using one DB2 9.7 for Linux system per student.

Målgrupp:

This is an advanced course for database designers, database administrators, and application developers working with DB2 9 for Linux, UNIX,and Windows who are concerned about performance in both single and multiple partition databases.

Målsättning:
