Sleepycat Software Releases New Version of Berkeley DB

New high availability features and efficiency improvements give developers

greater control and superior performance

EMERYVILLE Calif., November 29, 2005 – Sleepycat Software, makers of the

world’s most widely deployed open source developer databases, today

announced the general availability of version 4.4 of Berkeley DB, their

flagship database that is used in more than 200 million deployments. A

number of new replication features and efficiency improvements have been

added in response to customer demand.

Berkeley DB now supports in-memory replication, client-to-client

replication, controls for throttling and delaying synchronization and master

election speed-ups. Additional feature additions include online Btree

compaction and disk reclamation, abandoned lock removal, automated recovery

serialization and a hot backup utility.

“Sun Microsystems uses Berkeley DB within several products in our software

portfolio such as the Sun Java System Portal Server, Identity Manager and

Directory Server,” said William Franklin, Senior Director, Database

Technology at Sun Microsystems. “Berkeley DB 4.4 adds a number of important

enhancements that we will be able to leverage. We value Sleepycat products’

consistently high performance, reliability and scalability.”

“Berkeley DB has for many years been one of the options available within

MySQL’s pluggable storage engine architecture,” said Marten Mickos, CEO of

MySQL AB. “Developers can choose the storage engine whose features and

performance best meets the needs of the application. Berkeley DB is very

fast and supports ACID transactions, and we continue to collaborate with

Sleepycat to ensure our products are well integrated.”

“Berkeley DB’s massive user base continues to help us advance the state of

the art in database technology,” said Mike Olson, CEO of Sleepycat Software.
