This course teaches database administrators to perform basic database administrative tasks using Db2 11.1. These tasks include creating database objects like tables, indexes and views, and loading data into the database with Db2 utilities like LOAD and INGEST. Various diagnostic methods will be presented, including using db2pd command options, and monitoring with SQL statements that reference Db2 monitor functions. Students will learn how to implement automatic archival for database logs and how to recover a database to a specific point in time using the archived logs. The course covers using EXPLAIN tools to review the access plans for SQL statements and adding indexes to improve SQL performance. We will cover the locking performed by Db2 and the effect the application isolation level has on locking and lock wait conditions. Students will learn how to implement database security, including adding a security administrator, SECADM user, and implement database roles to simplify security management. We will also describe implementing Db2 native encryption for a database.

The lab demonstrations are performed using Db2 11.1 for Linux. For some lab tasks, students will have the option to complete the task using a Db2 command line processor, or using the graphical interface provided by IBM Data Server Manager.

This is an intermediate level course for students that will perform Database Administration tasks, who plan, implement, and maintain Db2 11.1 databases. These skills can also be utilize to support cloud based databases using IBM Db2 on Cloud or IBM Db2 Hosted.

Participants should have the following skills: o Perform basic database administration tasks on a relational database system 

• Use basic OS functions such as utilities, file permissions, hierarchical file system, commands, and editor

• State the functions of the Structured Query Language (SQL) and be able to construct DDL, DML, and authorization statements

• Discuss basic relational database concepts and objects such as tables, indexes, views, and joins

These skills can be developed by taking: 

• DB2 SQL Workshop

• DB2 Fundamentals
