DB2 for LUW Advanced Database Administration for Experts

Course Overview

This course is designed to help you:

• 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.
• Investigate the DB2 LUW process model, including its processes for log management, Input/Output (I/O) prefetching, page cleaning and utility processing for load, backup, and restore.
• 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.
• Utilise the REORG Utility to implement row compression for large tables, to reduce disk utilization and improve I/O performance for a DB2 database.
• 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.
• 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 utilisation of a wide variety DB2 LUW utilities and functions by performing a series of lab exercises using DB2 Enterprise 9 installed on a Linux platform. The exercises build skills that can be applied to DB2 database servers on any Linux, UNIX or Windows environment.

Audience

This is an advanced course for DB2 LUW experienced database administrators who support DB2 for UNIX, Windows, and Linux databases.

Skills Gained

After completing this course, you should be able to:

• Monitor a DB2 LUW database using command line processor queries
• Use the db2diag command to search the DB2 diagnostic log messages to resolve various common database problems
• Configure a DB2 database for autonomic utilities, including database statistics collection and table reorganization
• Analyze REORGCHK reports to determine if the table or the index reorganization would improve database efficiency.
• Invoke and monitor the processing for the REORG utility running offline or online
• Manage the disk space allocated in DMS table spaces using ALTER TABLESPACE to extend or to reduce the containers, and monitor the progress of the DB2 rebalancer process
• Implement automatic resize for DMS table spaces or Automatic Storage management for table spaces to reduce the complexity of managing DB2 LUW databases
• Use the DB2LOOK utility to extract the Data Definition Language (DDL) for existing database objects
• Plan and execute the DB2MOVE utility to copy selected table data for an entire schema for objects from one DB2 database to another
• Configure the TCP/IP connections from DB2 clients to DB2 database servers to support application access or remote administration by database administrators
• Plan the movement of DB2 databases or tablespaces using the Backup and Restore utilities or using the db2relocatedb command with non-DB2 utilities.
• Plan and implement MDC tables to improve application performance, including selecting the appropriate table space extent size
• Utilise range-based partitioned tables to support large DB2 tables that require very efficient roll-in and roll-out capabilities
