This manual describes the Oracle Transparent Gateway for Teradata, which enables Oracle client applications to access Teradata data through Structured Query Language (SQL). The gateway, with the Oracle database server, creates the appearance that all data resides on a local Oracle database server, even though the data can be widely distributed.
This preface covers the following topics:
This manual is intended for Oracle database administrators who perform the following tasks:
Installing and configuring the Oracle Transparent Gateway for Teradata
Diagnosing gateway errors
Using the gateway to access Teradata data
Note:
You should understand the fundamentals of transparent gateways and the Solaris Operating System (SPARC) before using this guide to install or administer the gateway.Our goal is to make Oracle products, services, and supporting documentation accessible, with good usability, to the disabled community. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.

This section describes the conventions used in the text and code examples of this documentation set. It describes:
Conventions in Text
We use various conventions in text to help you more quickly identify special terms. The following table describes those conventions and provides examples of their use.
Convention | Meaning | Example |
---|---|---|
Bold | Bold typeface indicates terms that are defined in the text or terms that appear in a glossary, or both. | When you specify this clause, you create an index-organized table. |
Italics | Italic typeface indicates book titles or emphasis. | Oracle Database Concepts
Ensure that the recovery catalog and target database do not reside on the same disk. |
UPPERCASE monospace (fixed-width) font |
Uppercase monospace typeface indicates elements supplied by the system. Such elements include parameters, privileges, datatypes, RMAN keywords, SQL keywords, SQL*Plus or utility commands, packages and methods, as well as system-supplied column names, database objects and structures, usernames, and roles. | You can specify this clause only for a NUMBER column.
You can back up the database by using the Query the Use the |
lowercase monospace (fixed-width) font |
Lowercase monospace typeface indicates executable programs, filenames, directory names, and sample user-supplied elements. Such elements include computer and database names, net service names and connect identifiers, user-supplied database objects and structures, column names, packages and classes, usernames and roles, program units, and parameter values.
Note: Some programmatic elements use a mixture of UPPERCASE and lowercase. Enter these elements as shown. |
Enter sqlplus to start SQL*Plus.
The password is specified in the Back up the datafiles and control files in the The Set the Connect as The |
lowercase italic monospace (fixed-width) font |
Lowercase italic monospace font represents placeholders or variables. | You can specify the parallel_clause .
Run |
Conventions in Code Examples
Code examples illustrate SQL, PL/SQL, SQL*Plus, or other command-line statements. They are displayed in a monospace (fixed-width) font and separated from normal text as shown in this example:
SELECT username FROM dba_users WHERE username = 'MIGRATE';
The following table describes typographic conventions used in code examples and provides examples of their use.
Convention | Meaning | Example |
---|---|---|
[ ] |
Anything enclosed in brackets is optional. |
DECIMAL (digits [ , precision ]) |
{ } |
Braces are used for grouping items. |
{ENABLE | DISABLE} |
| |
A vertical bar represents a choice of two options. |
{ENABLE | DISABLE} [COMPRESS | NOCOMPRESS] |
... |
Ellipsis points mean repetition in syntax descriptions.
In addition, ellipsis points can mean an omission in code examples or text. |
CREATE TABLE ... AS subquery; SELECT col1, col2, ... , coln FROM employees; |
Other symbols | You must use symbols other than brackets ([ ]), braces ({ }), vertical bars (|), and ellipsis points (...) exactly as shown. |
acctbal NUMBER(11,2); acct CONSTANT NUMBER(4) := 3; |
Italics
|
Italicized text indicates placeholders or variables for which you must supply particular values. |
CONNECT SYSTEM/system_password DB_NAME = database_name |
UPPERCASE |
Uppercase typeface indicates elements supplied by the system. We show these terms in uppercase in order to distinguish them from terms you define. Unless terms appear in brackets, enter them in the order and with the spelling shown. Because these terms are not case sensitive, you can use them in either UPPERCASE or lowercase. |
SELECT last_name, employee_id FROM employees; SELECT * FROM USER_TABLES; DROP TABLE hr.employees; |
lowercase |
Lowercase typeface indicates user-defined programmatic elements, such as names of tables, columns, or files.
Note: Some programmatic elements use a mixture of UPPERCASE and lowercase. Enter these elements as shown. |
SELECT last_name, employee_id FROM employees; sqlplus hr/hr CREATE USER mjones IDENTIFIED BY ty3MU9; |
