Sleepycat Software is pleased to announce:

Berkeley DB 4.4.16
http://www.sleepycat.com/products/bdb.html

The Berkeley DB 4.4 release introduces a number of important new
features in three major functional areas.
The first area is in limiting when database environment recovery
needs to be performed. The Berkeley DB 4.4 release introduces the
ability to abort transactions and release locks held by processes that
have failed, without exiting the database environment and performing
recovery. In addition, the 4.4 release also introduces the ability to
serialize the database environment creation process, performing
recovery automatically as necessary. This feature can significantly
simplify the architecture of applications comprised of multiple
concurrent processes.
The second area is database compaction. The Berkeley DB 4.4
release introduces the ability to compact databases, optionally
returning space to the underlying filesystem. Database compaction does
not require the database be quiescent, and can be performed
concurrently with other database access.
The third area is replication for highly available systems. The
Berkeley DB 4.4 release supports replication sites that run entirely
in-memory, and replication hot initialization and election performance
have been significantly improved.
Finally, this release includes new documentation designed to aide
in the development of transactional applications. This comprehensive
guide examines all of the critical elements involved in good systems
design, implementation, and management when working with Berkeley DB's
transactional features.

The list of new features and benefits of Berkeley DB 4.4.16 include:

1. In-memory replication
2. Client-to-client replication
3. Delayed client synchronization
4. Synchronization throttling
5. Master election speed-ups
6. Hot backup utility
7. Online Btree compaction (index optimization)
8. Online Btree disk space reclamation
9. Online abandoned lock removal
10. Automated recovery serialization
11. Transactional Application Developer's Guide

Sleepycat's mission is to provide the fastest, most reliable and
scalable transactional database for developers. Â*Our products include:

** Berkeley DB - With over 200 million active deployments in use
today, it's hard to make it through the day without somehow
coming in contact with something that relies on Berkeley DB.
(http://www.sleepycat.com/pdfs/oc_wherescat_0704.pdf)

** Berkeley DB XML - A native XML database with an optimized
XQuery access layer built atop Berkeley DB.

** Berkeley DB Java Edition - A pure Java version of Berkeley DB
without sacrificing speed or scale. This database is the best
solution to non-relational storage requirements for Java programs.

If you're building a software product or system that requires
dependable data storage, you owe it to yourself to evaluate our
software libraries. Â*Chances are one of our database engines will suit
your needs.
