2 Overview of Cache

Caching in TimesTen provides the ability to transfer data between an Oracle database and a TimesTen database. You can cache Oracle Database data and reduce the workload on the Oracle database. You can configure for read-only or read-write caching for Oracle database tables.

Use caching to improve the performance for your applications access to data. Caching offloads computing cycles from Oracle databases and enables responsive and scalable applications.

A cache in TimesTen:

• Loads a subset of the Oracle database tables into a TimesTen database.

• Can automatically maintain data synchronization between the cached data in the TimesTen database and the source data in the Oracle database.
