Oracle updates BerkeleyDB

Version 4.5 released

Oracle has released Version 4.5 of BerkeleyDB, the embeddable database it acquired in February through the purchase of SleepyCat Software.

New features in BerkeleyDB 4.5 include multiversion concurrency control for databases often accessed by many users at once, the ability to install upgrades and patches in replicated BerkeleyDB environments without taking the database off-line, and a pre-built replication environment for easier deployment of high-availability systems.

The previous 4.4 update to BerkeleyDB, which can be used for free or with commercial support provided by Oracle, was released about a year ago. The database has been deployed more than 200 million times, including in the Linux and BSD Unix operating systems, the Apache web server, OpenLDAP directory and OpenOffice productivity suite.

The database took a blow recently when MySQL, the maker of the MySQL database, quietly dropped support for BerkeleyDB (See Computerworld, September 25). MySQL will no longer allow BerkeleyDB to serve as one of its storage engines.
