Preface

Oracle TimesTen In-Memory Database (TimesTen) is a relational database that is memory-optimized for fast response and throughput. The database resides entirely in memory at runtime and is persisted to disk storage for the ability to recover and restart. Replication features allow high availability. TimesTen supports standard application interfaces JDBC, ODBC, and ODP.NET, in addition to Oracle interfaces PL/SQL, OCI, and Pro*C/C++. TimesTen is available separately or as a cache for Oracle Database.

This is a reference document for PL/SQL packages provided with TimesTen.

The following topics are discussed in the preface:

Audience

Oracle TimesTen In-Memory Database PL/SQL Packages Reference is a reference for programmers, systems analysts, project managers, and others interested in developing database applications using PL/SQL. This manual assumes a working knowledge of application programming and familiarity with SQL and PL/SQL to access information in relational database systems.

Related Documents

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

http://www.oracle.com/technetwork/database/database-technologies/timesten/documentation/index.html

Oracle TimesTen In-Memory Database PL/SQL Developer's Guide is especially relevant.

Oracle Database documentation is also available on the Oracle Technology network. This may be especially useful for Oracle Database features that TimesTen supports but does not attempt to fully document:

In particular, the following Oracle Database documents may be of interest.

  • Oracle Database PL/SQL Language Reference

  • Oracle Database PL/SQL Packages and Types Reference

  • Oracle Database SQL Language Reference

  • Oracle Database Reference

In addition, numerous third-party documents are available that describe PL/SQL in detail.

Conventions

TimesTen supports multiple platforms. Unless otherwise indicated, the information in this guide applies to all supported platforms. The term Windows applies to all supported Windows platforms. The term UNIX applies to all supported UNIX and Linux platforms. Refer to the "Platforms" section in Oracle TimesTen In-Memory Database Release Notes for specific platform versions supported by TimesTen.

Note:

In TimesTen documentation, the terms "data store" and "database" are equivalent. Both terms refer to the TimesTen database.

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 commands, URLs, procedure and function names, package 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, as in the following example.

Driver=install_dir/lib/libtten.sl

This means you should 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.

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.
TTinstance The instance name for your specific installation of TimesTen. Each installation of TimesTen must be identified at install time with a unique 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 The first three parts in a release number, with or without dots. The first three parts of a release number represent a major TimesTen release. For example, 1122 or 11.2.2 represents TimesTen 11g Release 2 (11.2.2).
DSN The data source name (for the TimesTen database).
