Oracle Processes

Summary

We’ve covered the files used by Oracle, from the lowly but important parameter file to data files, redo log files, and so on. We’ve taken a look inside 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 (or threads, depending on the operating system) that enable Oracle to do what it does. Now we are ready to look at the implementation of some other features of Oracle, such as locking, concurrency controls, and transactions.
