On successful completion of this course you will be able to:

• use the Db2 Toolset
• define / maintain Db2 objects using DDL statements CREATE, ALTER and DROP
• define partitioning databases and tables
• use IBM Data Studio and the Data Studio Web Console
• run IMPORT, EXPORT and LOAD statements
• perform BACKUP, RESTORE, RECOVER and ROLLFORWARD commands
• understand the concepts of High Availability Disaster Recovery (HADR)
• define Referential Integrity constraints and Table Check constraints
• resolve integrity violations
• understand the application development process
• bind plans and packages
• understand and resolve locking issues

• investigate system, application and SQL performance issues
• perform database replication tasks.

Who Should Attend

All those who will be working as database administrators in a Db2 Database (i.e. LUW) environment.

Prerequisites

Familiarity with the host environment is required. Prior exposure to Db2 or another relational database would be advantageous but not essential.
