In the Oracle database Oracle RDBMS environment, redo logs comprise files in a proprietary format which log a history of all changes made to the database . Each redo log file consists of redo records. A redo record, also called a redo entry, holds a group of Change vector s, each of which describes or represents a change made to a single block in the database. For example, if a user code UPDATE code s a salary value in a table containing employee related data, the DBMS generates a redo record containing change vectors that describe changes to the data segment block for the table. And if the user then code COMMIT code s the update, Oracle generates another redo record and assigns the change a system change number SCN . Whenever something is changed on a datafile, Oracle records it in the redo log. The name redo log indicates its purpose When the database crashes, oracle can redo all changes on datafiles which will take the database data back to the state it was when the last redo record was written. Use v log, v logfile, v log history and v thread to find information about the redo log of your database. Each redo log file belongs to exactly one group of which at least two must exist . Exactly one of these groups is the CURRENT group can be queried using the column status of v log . Oracle uses that current group to write the redo log entries. When the group is full, a log switch occurs, making another group the current one. Each log switch causes checkpoint, however, the converse is not true a checkpoint does not cause a redo log switch. You can also manually cause a redo log switch alter system switch logfile.

As comparison, SQL server computer cluster cluster s enable automatic failover, but at the expense of much higher storage and license costs.

unreferenced date February 2008 An intent log is a mechanism used to make computer operations more resilient in the event of failures. They are used in database software , transaction managers, and Journaling file system some file system s. In database area, transaction log is widely used. In file system area, intent log is used more often. Before performing an operation, a record of the intent to perform it is written, usually to some relatively permanent medium such as disk. After the operation is performed, another record is written. Usually, an operation will change some data in a system. In some cases, the intent record will contain a copy of the data before and after the operation. This adds overhead, sometimes a significant amount. Enough data is written to the log to either redo or to undo the operation later. If a failure occurs, then when the system is recovering, it can use the intent log to detect what operations were still in process during the failure, and use the intent log to help recover from the failure, usually by either undoing a partially completed operation, or by redoing one that might need to be completed.

A server log is a Data logging log file or several files automatically created and maintained by a Server computing server of activity performed by it. A typical example is a web server log which maintains a history of page requests. The World Wide Web Consortium W3C maintains a standard format the Common Log Format for web server log files, but other proprietary formats exist. More recent entries are typically appended to the end of the file. Information about the request, including client computing client IP address , request Calendar date date time , webpage page requested, Hypertext Transfer Protocol HTTP code, bytes served, user agent , and HTTP referrer referrer are typically added. These data can be combined into a single file, or separated into distinct logs, such as an access log, error log, or referrer log. However, server logs typically do not collect user specific information. These files are usually not accessible to general Internet users, only to the webmaster or other administrative person. A statistical analysis of the server log may be used to examine traffic patterns by time of day, day of week, referrer, or user agent. Efficient web site administration, adequate hosting resources and the fine tuning of sales efforts can be aided by analysis of the web server logs. Marketing departments of any organization that owns a website should be trained to understand these powerful tools.

The log probability representation is to store a probability math x in 0, 1 math as math x log x in mathbb R math . The product of probabilities math x cdot y math can be written as math x y math the sum of probabilities math x y math is more complex to express and is written as math log e x e y math . Note, however, that we can avoid to incur the cost of this computation by approximating the sum of two probabilities by the highest probability, at the expense of accuracy. Representing probabilities in this way has two main advantages Speed. Since multiplication is more time complexity expensive than addition, taking the product of a high number of probabilities is faster if they are represented in log form. The conversion to log form is expensive, but is only incurred once. Accuracy. The use of log probabilities improves numerical stability .
