Preface

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 ODBC (Open DataBase Connectivity), OCI (Oracle Call Interface), Oracle Pro*C/C++ (precompiler for embedded SQL and PL/SQL instructions in C or C++ code), and PL/SQL (Oracle procedural language extension for SQL).

The TimesTen C++ Interface Classes (TTClasses) library was written to provide an easy-to-use, high-performance interface to TimesTen. This C++ class library provides wrappers around the most common ODBC functionality.

This preface covers the following topics:

Audience

This guide is for application developers who administer and access TimesTen through C++.

In addition to familiarity with the particular programming interface you use, you should be familiar with TimesTen, SQL (Structured Query Language), database operations, and ODBC.

Related documents

TimesTen documentation is available on the product distribution media and on the Oracle Technology Network:

http://www.oracle.com/technology/documentation/timesten_doc.html

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, such as OCI and Pro*C/C++:

In particular, these Oracle documents may be of interest:

This manual occasionally refers to ODBC APIs. ODBC API reference documentation is available from Microsoft or a variety of third parties. For example:

This document uses the following text conventions:

Convention Meaning
italic Italic type indicates book titles, emphasis, or placeholder variables for which you supply particular values.
monospace Monospace type indicates code, commands, URLs, class names, function names, method 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 variable in a code example that you must replace. For example:

Driver=install_dir/lib/libtten.sl

Replace install_dir with the path of your TimesTen installation directory.

[ ] 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.
% The percent sign indicates the UNIX shell prompt.
# The number (or pound) sign indicates the UNIX root prompt.

TimesTen documentation uses these variables to identify path, file and user names:

Convention Meaning
install_dir The path that represents the directory where the current release of TimesTen is installed.
TTinstance The instance name for your specific installation of TimesTen. Each installation of TimesTen must be identified at install time with a unique alphanumeric instance name. This name appears in the install path.
bits or bb Two digits, either 32 or 64, that represent either the 32-bit or 64-bit operating system.
release or rr Numbers that represent a major TimesTen release, with or without dots. For example, 1121 or 11.2.1 represents TimesTen Release 11.2.1.
DSN The data source name.

Documentation Accessibility

Our goal is to make Oracle products, services, and supporting documentation accessible to all users, including users that are disabled. 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.
