This training will provide you with insights into the internal processing of SQL statements by Oracle. We look into statistics, the execution plan and the different tuning options like indexes, joins, bulk operations, hints and various storage techniques. We go into detail of understanding the the execution plan: how to read it, what the different steps mean and how the execution plan can be influenced. In addition, we dive into the automatic tuning, as Oracle has from version 10g. When tuning, not only the individual statements are important, but also the application as a whole, so we also include them in our hunt for more speed.
During the training we use SQL Developer, the Enterprise Manager, but you also work from command-line tool SQL * Plus. This makes our training platform independent.
This training is suitable for anyone using version 11g and higher. Version dependent features are specifically indicated.
Each participant will have access to their own database to practice extensively after we have discussed the theory. During these exercises we naturally pay attention to improving statements!
