As the size of databases and data warehouses increases, one cannot rely upon the default features of the Oracle database to sufficiently process such massive volumes of information. One must employ advanced features intended for such environments. In fact, these features are at the same time, among the most powerful tuning options available within the Oracle database yet some of the least understood and utilized. The purpose of this course is to equip database professionals with the skills to utilize such advanced features as these:
• The full range of table partitioning options, including range, hash, list, and composite partitioning schemes.
• The full range of index partitioning options, including local and global partitioned indexes.
• Discuss the broad conceptual rationales one may base partition schemes on. These various possibilities are illustrated using two different sample data models.
• The performance benefits of using database object partitions and monitoring the execution of SQL statements under the control of the partition-aware Optimizer.
• Understanding the operations within a complex SQL execution plan that operates in parallel upon partitioned objects.
• General principles of parallel processing and their use in Oracle database technology.
• The specific feature of parallel SQL execution and the configuration options available to activate and administer this technology.
