Hi all,
Meet us next week at ApacheCon'04 and don't miss the following sessions
involving the ObjectWeb community:
WE09: High-speed ObjectWeb Logger (HOWL) for J2EE Application
Servers
Day: Wed
Time: 13h30
Session chair: None assigned
Duration: 60 minutes
Style: Presentation
Level: Experienced
Audience: Technical
Categories: E-Commerce, Java, Performance
Speaker: Michael Giroux
- Abstract:
- This session provides an overview of the implementation,
performance objectives and current development status of the
High-speed ObjectWeb Logger (HOWL) project. HOWL is currently
integrated in Apache Geronimo, Codehaus ActiveMQ and ObjectWeb
JOTM. J2EE Application Servers implement Transaction
Management supporting coordination of transactions across multiple
Resource Managers using XA 2-Phase-Commit protocol. Persisting
the state of active transactions using a transaction journal
is a requirement for recovery from a system failure, such as
the loss of a participating Resource Manager. Writing journal
records without significantly impacting system performance
is key to a successful transaction journal implementation. The
Geronimo project has a stated performance objective of
10,000 TX/Sec, and the transaction log should use no more than 25%
CPU. The presentation will describe the techniques used in
HOWL to meet this requirement.
MO15: Highly available web sites with Tomcat and Clustered JDBC
Day: Mon
Time: 14h30
Session chair: None assigned
Duration: 60 minutes
Style: Presentation
Level: Experienced
Audience: Technical
Categories: E-Commerce, Java, New Technologies, Performance
Speaker: Emmanuel Cecchet
- Abstract:
- Tomcat clustering capabilities have proven useful for
building scalable and highly available web or e-commerce sites.
However, the database usually becomes the bottleneck and a
single point of failure. This talk will show you how to build
end-to-end highly available web sites using Clustered JDBC
(http://c-jdbc.objectweb.org) with Tomcat. C-JDBC provides
clustering techniques at the JDBC level which makes it database
independent (MySQL, PostgreSQL, Firebird, ...). Moreover, C-JDBC
does not require application to your existing servlets. We
will present different Tomcat+C-JDBC configurations offering
various performance, fault tolerance and availability tradeoffs.
The session will also feature a demo of the administration
tools. Involved technologies are:
- Apache HTTP Server
- mod_jk
- Tomcat clustering
- JDBC, C-JDBC
- PostgreSQL, MySQL, HypersonicSQL
- JMX (for admin)
BOF01: Collaborating Communities: Geronimo, ObjectWeb, more
Day: Mon
Time: 20h00
Duration: 60 minutes
- Abstract:
- This is for the entire Geronimo team, the ObjectWeb
community, and others like ActiveMQ, OpenEJB, Mx4J, where we talk
about how we've been working together for over 1 year now,
relicensing for the benefit of each other (OW did it for us),
forming projects together (we helped found HOWL at OW), etc.
BOF13: J2EE Clustering
Day: Tue
Time: 21h00
Duration: 60 minutes
- Abstract:
- How to build an end-to-end scalable and reliable J2EE
cluster using just open source components? How to integrate these
components and their various administration tools? This BOF
will be of interest for Apache, Tomcat, Geronimo, C-JDBC and
their related communities, as well as all people interested in
performance, monitoring and configuration issues.
The full agenda is available on the conference web site:

See you there,
