Oracle TimesTen In-Memory Database is a memory-optimized relational database. Deployed in the application tier, TimesTen operates on databases that fit entirely in physical memory using standard SQL interfaces. High availability for the in-memory database is provided through real-time transactional replication.
TimesTen supports a variety of programming interfaces, including JDBC (Java Database Connectivity) and PL/SQL (Oracle procedural language extension for SQL).
This preface covers the following topics:
This guide is for anyone developing or supporting applications that use TimesTen through JDBC.
In addition to familiarity with JDBC, you should be familiar with TimesTen, SQL (Structured Query Language), and database operations.
TimesTen documentation is available on the product distribution media and on the Oracle Technology Network:
http://www.oracle.com/technetwork/database/timesten/documentation/
Javadoc for standard JDBC classes and interfaces is available at the following location:
https://download.oracle.com/javase/1.5.0/docs/api/
Oracle documentation is also available on the Oracle Technology network. This may be especially useful for Oracle features that TimesTen supports but does not attempt to fully document:

In TimesTen documentation, the terms "data store" and "database" are equivalent. Both terms refer to the TimesTen database unless otherwise noted.This document uses the following text conventions:
| Convention | Meaning |
|---|---|
| italic | Italic type indicates terms defined in text, book titles, or emphasis. |
monospace |
Monospace type indicates code, commands, URLs, class names, interface names, method names, function names, attribute names, directory names, file names, text that appears on the screen, or text that you enter. |
italic monospace |
Italic monospace type indicates a placeholder or a variable in a code example for which you specify or use a particular value. For example:
Replace |
| [ ] | Square brackets indicate that an item in a command line is optional. |
| { } | Curly braces indicated that you must choose one of the items separated by a vertical bar ( | ) in a command line. |
| | | A vertical bar (or pipe) separates alternative arguments. |
| . . . | An ellipsis (. . .) after an argument indicates that you may use more than one argument on a single command line. An ellipsis in a code example indicates that what is shown is only a partial example. |
| % | The percent sign indicates the UNIX shell prompt. |
TimesTen documentation uses these variables to identify path, file and user names:
| Convention | Meaning |
|---|---|
install_dir |
The path that represents the directory where TimesTen is installed. |
