June 2001, Oracle launched a new generation of Internet e-commerce infrastructure Oracle9i.
Oracle9i key focus areas include:
• Providing the world's leading zero data loss protection of the environment
• Through the support of more on-line operation off-line maintenance requirements to reduce
• Provide for the damaged database fast and accurate repair
* Allows end users to identify and correct their own errors
The world's leading data protection environment
Oracle9i includes many new features to improve data protection. In addition to the existing products of the Standby key enhancements, including a provision monitoring, automation and control framework.
And management of the standby database is on the automation of many tasks, including initialization instance, the error jumps and easily switch back and forth between master and slave. Administrators can also optionally specify that each backup site lags behind the production environment, delayed application of the log (to relieve human error or damaged line errors) and select a zero data loss mode, in this mode redo logs to be synchronized sent to the alternate site.
Also enhanced in Oracle9i LogMiner, in order to provide full SQL-based Log Analysis (log analysis). LogMiner now supports indexing of clustered tables, chain line, direct load, scalar object type, LOB, LONG data types and DDL. LogMiner also showed support for the primary key and change the content based on query logs (for example, show the employee "Smith" all changes). A new graphical user interface and other database features also make this product easy to learn, easy to use.
Online Data Evolution
Oracle9i contains a new online re-organization and re-define the architecture, this architecture provides a more powerful re-organization capabilities. Administrators can now define the table to perform various on-line operations, including the heap-organized tables online re-organization. In essence, Oracle9i now allows on-line "CREATETABLEASSELECT" operation. In this new architecture, the table is copied to a new table. While copying the contents of the database to track updates to the original table. The copy is complete, updates will be applied to the new table. Once the update is applied, you can create indexes on the new table. After creating the index will be applied to any other updates, and the results table will replace the original table. Updating the dictionary data, while only in operation at the beginning and end of the lock table in exclusive mode. Using this new architecture, you can change the form of any online physical properties. Table can be moved to a new location, a table can be partitioned, the table can also be from an organization (such as deposits) to another organization (such as indexing of).
In addition, many logical properties can be changed. For example, you can change the column name, type and size, and columns can be added, deleted or merged. The main restriction is not to modify the table's primary key.
Oracle9i also supports the current index-organized tables online last level index create, rebuild, and so on. Can now be created online indexes and analyze them simultaneously. Secondary indexes support efficient use of the block tips.
Administrators can quickly stop the database in order to perform the requested operation inactive transaction. In addition, you can dynamically adjust the Oracle9i buffer cache and shared pool size. Finally, Oracle9i can also be the object the user is online and is accessible and to verify the structure of objects (analytical validation).
Accurate database repair
Oracle8i contains very complete recovery. Oracle9i by making them more powerful and more accurate they were extended.
Oracle9i includes disk damage
In 2004, the release oralce10g.
July 12, 2007, Oracle announced a database in the United States New York, Oracle 11g, which is the latest version of the Oracle database
