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 guide describes how to troubleshoot some of the problems users encounter when using the Oracle TimesTen In-Memory Database.
To work with this guide, you should understand how database systems work and have some knowledge of SQL (Structured Query Language).
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.
