Before you start fidgeting with individual SQL statements, it is important to note that hints are probably the last thing you should consider adding when attempting to optimize your code. There are several levels of optimization and it is recommended that you start with the server, then the database instance, and finally go down through the database objects to individual statements. After all, the effect of any changes made to individual statements, particularly hints, may be lost when the database is fine-tuned later on.

This guide provides information about tuning Oracle Database for performance. Topics discussed in this guide include:. Based on years of designing and performance experience, Oracle has designed a performance methodology. This part describes activities that can dramatically improve system performance and contains the following topics:. Part III, "Optimizing Instance Performance" discusses the factors involved in the tuning and optimizing of an Oracle database instance. When considering instance tuning, take care in the initial design of the database to avoid bottlenecks that could lead to performance problems. In addition, you must consider:.

The nightmare of every Oracle database admin is receiving a flurry of calls from users complaining that their online performance is running slow. When systems are slow or unresponsive, Oracle performance tuning is one of the best ways to identify bottlenecks and ensure your infrastructure is equipped to handle increased loads. Here are five Oracle performance tuning tips that will help you get the most out of your database efforts and keep your environment fully operational. One of the most effective tuning methods is to maintain an established performance baseline that you can reference when a performance problem occurs. By easily identifying peak usage periods, you can set performance targets and have a firm understanding of your system capabilities. Consistently measuring existing performance provides exact expectations of how your database should be running, which is quite helpful when tuning any bottlenecks that will inevitably come up in the future. One of the most useful Oracle Database performance tuning features is the Automatic Workload Repository AWR , which collects, processes, and maintains performance statistics.

After the initial configuration of a database, tuning an instance is important to eliminate any performance bottlenecks. This chapter discusses the tuning process based on the Oracle performance views. Propose changes to be made and the expected result of implementing the changes. Then, implement the changes and measure application performance. The remainder of this chapter discusses instance tuning using the Oracle dynamic performance views.


Another serious concern in the realm of SQL tuning is the avoidance of SQL performance degradation after database upgrades. In this paper, we will look at SQL.

Сьюзан швырнула ему под ноги настольную лампу, но Хейл легко преодолел это препятствие. Он был уже совсем. Правой рукой, точно железной клешней, он обхватил ее за талию так сильно, что она вскрикнула от боли, а левой сдавил ей грудную клетку. Сьюзан едва дышала. Отчаянно вырываясь из его рук, Сьюзан локтем с силой ударила Хейла. Он отпустил ее и прижал ладони к лицу. Из носа у него пошла кровь.
