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:
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.
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.
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.
