Oracle TimesTen In-Memory Database

Back in June of '05, Oracle acquired in-memory database builders TimesTen. Today, Oracle has released the next generation of the TimesTen product, featuring 11 microsecond data read-request response time, and 30 microsecond update times. The product can be deployed stand-alone as a 100% in-memory application (the DB itself and the database engine), or can be used as a front-end cache to an Oracle 10g disk-based DB.

Deployed standalone, the Oracle TimesTen DB can be accessed by applications via TimesTen-supplied libraries, or under a client-server model supporting SQL, ODBC, and JDBC. The DB is robust and easy to administer -- transaction logging and checkpointing can be controlled by applications at the transaction level. A sophisticated optional replication module lets you set up multiple Oracle TimesTen DBs in a conventional Master/Subscriber arrangement, or in arrangements where two databases replicate one another mutually, or in a replication cascade, where subscribers (i.e., to a single master DB) can in turn become masters to other DBs.

The Oracle TimesTen In-Memory Database is available now, with pricing starting at $12,000 per CPU. The two options (replication and caching) start at $6,000 per CPU each. All prices depend on the size of the in-memory DB.

The product can be downloaded from Oracle under a developers-only licensing agreement.
