Introducing Database Administration
In This Guide
This guide provides Actian X database administrators with information about creating, maintaining, backing up, and recovering databases.
Audience
This guide is primarily intended for database administrators. In some cases, however, the responsibilities of the database administrator and the system administrator overlap. Therefore, some of the tasks and responsibilities described in this guide require permissions typically given to the system administrator, but not necessarily given to database administrators. In these cases, you must work with your system administrator to carry out these responsibilities.
Database Administrator Responsibilities
Anyone who creates a database becomes the database administrator (DBA) for that database. Furthermore, there is no limit on the number of DBAs that can exist at a site.
Note:  Before you can create a database, you must have the createdb privilege.
The DBA has permission to do the following:
Create and destroy databases
Manage public database objects
Maintain database and query performance
Monitor locking to maximize concurrency
Back up and recover the database
Authorize databases to use alternate locations
Manage user access to data through grants on tables, views, procedures, and other objects.
For information on managing user access, see the Security Guide.
Database Administration Summary
The following table is a quick reference to the statements, commands, and utilities used to perform database administration tasks.
For details, refer to the appropriate chapter in this guide, the SQL Reference Guide, Command Reference Guide, and Security Guide. Many of these tasks can be also performed using Actian Director or the Visual Tools on Windows.
Note:  UPPERCASE denotes SQL statement; lowercase denotes command or utility.
