DB2 9 for LUW Advanced Database Administration for Experts CL462CZ

This is the classroom version of Instructor led online course DB2 9 for LUW Advanced Database Administration for Experts - ILO (3L462)

This course is designed to teach you how to:

• Fully use the advanced technical functions and features of DB2 LUW.
• Perform advanced monitoring using the DB2 administrative views and routines in SQL queries. Use the db2diag.log file messages to direct your investigation of problems using db2pd, INSPECT, db2support, and DB2 traces. Use DB2's health monitoring and Health Center to review the health indicator status for the instance, database, and table spaces. The type of problems monitored and resolved include buffer pool activity, lock contention, long running SQL statements, and log space utilization. Understand how automatic and manual first occurrence data capture can help to collect the diagnostic information needed to solve problems.
• Configure and manage the implementation of DB2 instance or database level auditing, including using the db2audit command and creation of audit policies which can be assigned to specific tables, users or database roles to perform selective collection of audit records.
• Explore DB2's management of disk space usage in Database Managed Storage (DMS) table spaces, including the activities of the rebalancer. Use DB2 commands and utilities to check the high water mark on table spaces and to monitor the rebalance operation. Move data from one table to another or from one database to another using utilities, such as db2move and db2relocatedb.
• Implement automatic storage management for table spaces or enable automatic resize options for DMS managed table spaces to reduce administration requirements and complexity.
• Exploit and monitor the REORG utility processing for offline and online table, and index reorganization This includes planning for the disk space and database log space necessary for reorganization. Configure the options and policies to automate the collection of table and index statistics or the reorganization of DB2 tables and indexes to improve performance and provide efficient disk space utilization. Monitor and review DB2's automated operations using health monitoring and diagnostic log messages.
• Utilize the REORG Utility to implement row compression for large tables, to reduce disk utilization and improve I/O performance for a DB2 database and understand the automatic creation of compression dictionaries.
• For Multidimensional Clustering (MDC) tables, determine how to select the dimension columns and table space extent size for efficient implementation of MDC tables. Compare the block indexes used for MDC table with rows based indexes. Select the MDC rollout option that best matches application needs and achieves the best performance results.
• Determine configuration options to use for connecting DB2 clients to DB2 LUW database servers using TCP/IP using the configuration assistant. Implement DB2 support for Lightweight Directory Access Protocol (LDAP) or DB2 thin client support to reduce administration requirements. Enablement of remote administration through use of DB2 Administration Server (DAS).
• Plan and implement range based table partitioning for large DB2 tables. Utilize the ALTER TABLE ATTACH and DETACH options to support roll-in and roll-out operations for range-partitioned tables. Compare the advantages of selecting or combining range partitioning with the hash-based partitioning used in DB2 DPF databases or the multiple dimensions provided by MDC tables.
• You get practical experience in the planning and utilization of a wide variety DB2 LUW utilities and functions by performing a series of lab exercises using DB2 Enterprise 9.5 installed on a Linux platform. The exercises build skills that can be applied to DB2 database servers on any Linux, UNIX or Windows environment.
