Oracle: Performance Tuning (1Z0-033) Tutorials

Course Content
VTC author, Gavin Powell, covers material in the 1Z0-033 Oracle 9i tuning certification examination, including the basics of performance tuning and tuning tools. Memory tuning covers the shared pool, the database buffer cache and other buffers. From an I/O perspective, topics covered are physical file structures of the database, tablespaces, datafiles and at the block level. Also covered are sorting, locking, latches and wait events, shared or dedicated server processes, statistics, SQL code tuning and resource management. There is also brief coverage of tuning in the operating system, plus specialized objects use. To begin learning today, simply click on one of the Oracle Performance Tuning (1Z0-033) lessons.
