Memory Structures,tionship. We saw how the mode in which we connect to Oracle will dictate how memory is organized. A dedicated server connection implies more memory used in the server process than under a shared server connection, but that use of a shared server connection implies there will be the need for a signif

Oracle Processes,e the memory structures used by Oracle, both in the server processes and the SGA. We’ve seen how different server configurations, such as shared server versus dedicated server mode for connections, will have a dramatic impact on how memory is used by the system. Lastly, we looked at the processes (o

Locking and Latching,effects are not. However, it is vital that you understand these issues. For example, if you were not aware of the table lock Oracle uses to enforce a foreign key relationship when the foreign key is not indexed, then your application would suffer from poor performance. If you did not understand how

Redo and Undo,for, since it is actually the DBAs or SAs who must correct these issues. The most important things to take away from this chapter are the significance of redo and undo, and the fact that they are not overhead—they are integral components of the database, and are necessary and mandatory.

Parallel Execution,cution is applicable, namely when we have long-running statements or procedures and plenty of available resources..Then we looked at how Oracle can employ parallelism. We started with parallel query and how Oracle can break large serial operations, such as a full scan, into smaller pieces that can r
