Sleepycat Software Releases New Version of Berkeley DB

New performance and high availability features strengthen popular open source
database for mission-critical telecommunication infrastructure and enterprise
datacenters


EMERYVILLE Calif., November 10, 2004   Sleepycat Software, makers of Berkeley
DB, the most widely used open source developer database in the world with
over 200 million deployments, today announced the general availability of
Berkeley DB 4.3.  The new release includes in-memory transaction logging as
well as other speed and ease-of-use enhancements to improve the development
of telecommunication and enterprise datacenter infrastructure software
meeting 99.999% carrier-grade availability requirements.

"Berkeley DB is faster and easier to use than ever before," said Mike Olson,
CEO of Sleepycat Software.  "We're continuing to push Berkeley DB deeper into
mission-critical environments by working closely with customers to enhance
Berkeley DB for carrier-grade environments where 24x7 uptime is mandatory."

"Speed, reliability and ease-of-use are important considerations for
telecommunication infrastructure equipment," said Rich Wong, General Manager
of the Messaging Group at Openwave.  "We're pleased that Sleepycat continues
to improve Berkeley DB for the telecommunications industry.  Openwave relies
on Berkeley DB as the core message store in Email Mx, a messaging platform
that handles more than 1.5 billion messages a day."

Berkeley DB 4.3 adds support for in-memory transaction logging, enabling fast
recovery in response to system failovers in a distributed database.  Since
disk is usually the slowest part of a database system, new features in
Berkeley DB gives the infrastructure developer the option of replicating the
session in system memory, enabling a high performance, high availability
system over a fast network.

New features in Berkeley DB 4.3 include:
 	Level 2 isolation for improved transaction throughput   Berkeley DB now
supports repeatable reads as well as committed reads (level 1 isolation);
 	Automatic initialization of replication clients, making it easier to set up
a fault-tolerant system;
 	Automatic sequence number generation   high speed databases frequently use
unique identifiers which commonly are a hotspot limiting application
scalability.  Berkeley DB now supports such sequences natively ensuring the
highest level of concurrency and improving overall application speed.

Of course 4.3 is not compatible with 4.2 or, probably 4.3.21.0.0.0.1. Oh, I have no doubt that I'll remember to run db43_recover instead of db42_recover the next time my BDB systems deadlock, lest I risk losing all my data, just like it says in that prominent statement buried 42 pages deep in the info docs.

Not that I'm BITTER or anything.

Any manual recovery activity seems to me a good time for a backup before.

This does not excuse any sloppy design, coding, or documentation. But system management has a few responsibilities, too.
