These days nearly every sizable organization has either implemented some form
of SOA or has it on their roadmap. They quickly find that SOA efforts tend to
expand like spider webs, eventually touching every corner of IT as well as
the business itself. Due to the vital role that data plays both in business
and systems operations, database architects, information specialists, data
integration experts, and anyone responsible for data persistence in an
organization are increasingly being called on to contribute to their
organization’s SOA initiatives – whether or not this was intended at the
onset.
Information locked away inside monolithic application silos has proven to be
a stubborn obstacle to the flexibility that modern businesses require. If
businesses are to have any hope of building flexible services that offer the
performance and agility needed to succeed with ... (more)
What's the best way to develop and fine-tune your WebSphere applications to
run faster, jump higher…and make fewer trips to the database?
When creating optimized WebSphere applications that access data on your DB2
database, what kinds of challenges do you face? Creating DB2-enabled
WebSphere apps involves the Java Database Connectivity (JDBC) API, which can
be a challenge in itself. This article will look at various DB2-enabled
applications and offer some guidelines to help your WebSphere applications
run more efficiently when they connect to a DB2 database.
Designing WebSphere A... (more)
Pooling is great - except it's not very tunable, it's hard to map end users
back to connections in the pool, and if a connection ever becomes invalid
inside the pool, expunging only that connection from the pool is nearly
impossible; JDBC 4.0 addresses all these drawbacks
As a member of every previous JDBC Expert Group, it sometimes seems as if the
specification process moves too slowly for the few features being added or it
seems as if the new feature list is good, but "not good enough." The JDBC 4.0
specification fits neither of these perceptions. The specification includes a

It's been over three years since the JDBC Expert Group held its first meeting
to gather requirements, requests, and pipe dreams for the JDBC 4.0
specification. In that meeting, we discussed a wide variety of topics,
including performance enhancements, clarifications on the existing JDBC 3.0
specification, and Ease of Development features. Unbelievably, everything but
the kitchen sink ended up making it into the release. In this article, we'll
look at several key features that made the enhancement list for JDBC 4.0, and
we'll discuss why those features are important.
At the time ... (more)
There was no ticker tape parade to accompany the release of the JDBC 3.0
specification, but many will be pleasantly surprised at its list of
enhancements that include everything from performance-tuning options to
support for extended-level database features.
This article describes, in detail, the new features that are available in
JDBC 3.0 and explains why they are important.
The JDBC 3.0 specification was shipped as part of the J2SE 1.4 release early
in 2002. The key goals of the JDBC Expert Panel were to align with the most
important features of SQL99, combine all the previous ... (more)
