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 PL/SQL (Oracle procedural language extension for SQL), ODBC (Open Database Connectivity), JDBC (Java Database Connectivity), OCI (Oracle Call Interface), Pro*C/C++ (Oracle precompiler for embedded SQL and PL/SQL instructions in C or C++ code), TTClasses (TimesTen C++ Interface Classes), and ODP.NET (Oracle Data Provider for .NET).

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.

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 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 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).
