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 document covers TimesTen support for PL/SQL.

The following topics are discussed in the preface:

Audience

This document is intended for anyone developing or supporting applications that use PL/SQL with TimesTen. Although it provides some overview, you should be familiar with PL/SQL or have access to more detailed documentation. This manual emphasizes TimesTen-specific functionality.

You should also be familiar with TimesTen, SQL (Structured Query Language), and database operations.

You would typically use PL/SQL through some programming interface such as those mentioned above, so should also consult the appropriate TimesTen developer documentation.

Also see "Audiences for this document", which goes into more detail.

Related documents

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

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, these Oracle Database documents may be of interest:

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 placeholder or a variable in a code example for which you specify or use a particular value, such as in the following 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. 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 the following 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 installation time with a unique instance name. This name appears in the installation path.
bits or bb Two digits, either 32 or 64, that represent either a 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 TimesTen data source name (for the TimesTen database).
