Globalization Support Features Globalization Support ensures that database utilities and error messages, sort order, date, time, monetary, numeric, and calendar conventions automatically adapt to the native language. Oracle currently supports 57 languages, 88 territories, 84 linguistic sorts (71 monolingual and 13 multilingual), and 235 encoded character sets. The language-dependent operations are controlled by a number of parameters and environment variables on both the client and the server sides. The server and the client may run in the same or different locations.

Data Loading Methods Several methods are available for loading data into tables in an Oracle database. Of the methods available, Direct Load insert and SQL*Loader are discussed here. Export and Import are covered in the Oracle9i Database Administration Fundamentals II course. SQL*Loader SQL*Loader loads data from external files into tables of an Oracle database. It has a powerful data parsing engine that places little limitation on the format of the data in the data file. Direct Load Direct Load insert can be used to copy data from one table to another table within the same database.

Auditing If an unauthorized user is deleting data, then the DBA might decide to audit all connections to the database and all successful and unsuccessful deletions from all tables in the database. The DBA can gather statistics about which tables are being updated, how many logical inputs/outputs (I/Os) are performed, and how many concurrent users connect at peak times.

Oracle provides for easy and controlled privilege management through roles. Roles are named groups of related privileges that are granted to users or to other roles. They are designed to ease the administration of privileges in the database. Role characteristics Roles can be granted to and revoked from users with the same commands that are used to grant and revoke system privileges. Roles can be granted to any user or role. However, a role cannot be granted to itself and cannot be granted circularly. A role can consist of both system and object privileges.
