This is the definitive course for DB2 DBAs. It teaches the skills that are essential for administrators, enabling them to provide effective and efficient database design, implementation and support. It explains the database design process, from the logical database model right through to the implementation of the physical database. The system architecture, operational facilities and utilities used in a DB2 for z/OS environment are fully explained and demonstrated. In addition, monitoring, security and recovery techniques are also covered.<br>This course is suitable for all environments up to and including DB2 11.<br><br>The comprehensive and challenging practical exercises in this course complement the formal tuition sessions, ensuring full understanding.<br><br>This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.
DB2 for z/OS: Database Design, Implementation & Administration
Attendees should be familiar with the DB2 environment and have knowledge of SQL or have attended the DB2 concepts and SQL courses.
- describe the internal structure and components of DB2 UDB for z/OS databases
- design and assess a logical database model
- design and implement efficient physical databases from the logical model using relevant options to create and amend storage groups, databases, table spaces, tables, indexes, aliases, synonyms, etc.
- understand and implement an effective locking strategy and use DB2 commands and other facilities to monitor locking for performance
- use EXPLAIN to evaluate the effectiveness of the database design
- describe the DB2 environment, and understand the use of key DB2 components such as buffer pools, the DB2 catalog and directory, logging data sets, etc.
- understand and assess security and related requirements
- understand and assess security and related requirementsuse DB2 commands to monitor and control DB2 objects, processes and operations
- understand and use the full complement of DB2 online data and recovery utilities
- understand and use the DB2 stand-alone utilities
- use DB2 traces to record performance monitoring information
- understand and interpret information in DB2PM accounting and statistics reports.
