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.

What You Need to Know
This guide assumes that you are familiar with the windowing system on the target platform of the installation, including terminology, navigational techniques, and working with standard items, such as menus and dialogs.
Query Language Used in this Guide
The industry standard query language, SQL, is used as the standard query language throughout this guide. Actian X is compliant with ISO Entry SQL-92. For details about the settings required to operate in compliance with ISO Entry SQL-92, see the SQL Reference Guide.
System-specific Text in this Guide
Generally, Actian X operates the same way on all systems. When necessary, however, this guide provides information specific to your operating system. For example:
Linux: Information is specific to the Linux environment.
Windows: Information is specific to the Windows environment.
When necessary for clarity, the symbol 
is used to indicate the end of system-specific text.
is used to indicate the end of system-specific text.For sections that pertain to one system only, the system is indicated in the section title.
Terminology Used in this Guide
This guide uses the following terminology:
• A command is an operation that you execute at the operating system level.
• A statement is an operation that you embed in a program or execute interactively from a terminal monitor.
Note: A statement can be written in Ingres 4GL, a host programming language (such as C), or a database query language (SQL).
Syntax Conventions Used in this Guide
This guide uses the following conventions to describe command and statement syntax:
Convention | Usage |
|---|---|
Monospace | Indicates keywords, symbols, or punctuation that you must enter as shown. |
Italics | Represent a variable name for which you must supply a value. |
[ ] (brackets) | Indicate an optional item. |
{ } (braces) | Indicate an optional item that you can repeat as many times as appropriate. |
