Course Objectives
This course is designed to teach database administrators advanced topics about Db2 for z/OS utilities with a combination of lecture materials and extensive lab exercises.
IBM Db2 utilities help you maintain data in your Db2 for z/OS databases. Generally, you use Db2 utilities to perform large-scale operations across one or more table spaces.
For example, you can use utilities to do the following maintenance tasks:
- Make copies of your data, which can later be used as a basis for recovery.
- Recover data, either to the current time or some point in the past.
- Load thousands or even many millions of rows into your database.
- Reorganize data so that space is used in the most efficient way possible.
Course Content
Use RUNSTATS to accelerate the performance of a given SQL access.
Employ DSN1COPY, REPAIR, and DIAGNOSE for DBA tasks which are not recovery oriented.
Use parallel index build with the LOAD, REORG and REBUILD INDEX utilities.
Load partitions in parallel.
Determine the appropriate LOAD options to use while considering concurrency and performance requirements.
Choose appropriate options with REORG and UNLOAD to achieve optimal performance and availability.
Provide appropriate LISTDEF, TEMPLATE, and OPTIONS utility control statements for use in DB2 utilities.
