Summary of the DBA Online seminar on April 26,
The dismal rainy weather
and the fear of SARS didn’t seem to affect the DBAOnline gathering -- around
200 members and guests attended DBAOnline’s 2003 April technical seminar
that was held in Clarion Hotel, Edison NJ.
The five-hour seminar started
when our hostess Ms. Yan Zhang introduced the president of DBAOnline and
Youngtech, Mr. David Wang, to the audience and welcomed him to give us
David briefly went over the
history of DBAOnline and its current position. Then he introduced current IT
industry trends and shared his vision on future development. He emphasized
that Linux technology has become more and more popular due to various
reasons. When he finished the speech referencing Larry Ellison’s statement:
“We’ll be running our whole business on Linux”, everybody could feel that
the Linux wave is looming.
Although configuring SQL*Net
connection is DBA’s 101 task, few people had experience with LDAP
technology. Mr. John Zhong, Senior Oracle DBA from Goldman Sachs, analyzed
the pros and cons of different SQL*Net connection methodologies, including
tnsnames and naming server. In detail he introduced LDAP, another way to set
up sqlnet administrations. His presentation covered details on how to add
TNS Service Names to an OID, how to configure and create an OracleContext.
Although it is still a quite new technology to most of the audience, LDAP
started to be widely used due to following reasons: easy administration and
implementation, flexibility, scalability and cost savings to the
companies. It should be one of
the skills that add value to our jobs.
Mr. Dave Anderson, founder
and senior instructor of Skillbuilders, gave us a presentation on oracle 9I
new features for DBA/developers. Even though many people were already quite
familiar with the topic, Dave’s instruction was so thorough and organized
that it certainly brought our 9i knowledge to a new height. Plus, he provided many ready-to-use
scripts to help us familiarize with the new features ourselves. Dave had
over 20 years of database experience and is a nationally recognized oracle
expert and speaker. We are very honored to have him as our speaker! The great news is: he also liked our
audience and agreed to present at our seminar again in the
This seminar is probably one
of the biggest events for DBAOnline. We had several vendors supported us
financially and enabled us to give quality IT education and advancement free
to the public. Among them are two of the biggest vendors in the industry,
Computer Associates and Quest Software Company. Mr. Jeff Surretsky,
technical team leader from Quest, explained some theories behind performance
tunings with his in-depth Oracle knowledge. He also introduced their new
tuning tool Quest Central that can leverage DBA’s tuning effort. Ms Sandra
Dearing from Computer Associates talked about the considerations involved
during decision-making processes as why and how to choose off-the-shelf
tools. It really gave us some guidelines when we need to use that analysis
methodology to purchase tools later.
It seemed to support David’s
“Why Linux” topic, Mr. Sean Hull, senior consultant and founder of iheavy
Inc, gave the presentation on Oracle on Linux -- low cost RAC with Firewire.
Sean instructed us with amazing details on how to set up a real oracle 9i
RAC on Linux with just a few hundred dollars. He also went over the whole
architectural picture of the RAC system. His presentation handout sure can
be our manual if we want to gain hands on experience on Linux and RAC and
add something impressive to our resumes.
As always, hours passed by
without notice. Quest software also brought the audience some good surprise:
there were T-shirts available for those people who dropped their business
cards at the door after seminar!
With or without T-shirt,
everybody had a great time.
Many attendees expressed that they enjoyed meeting their old and new
DBA friends as much as learning hot technologies.
At the end Yan thanked all
the speakers, vendors, guests and members for their work and involvement to
make the seminar another success.
