I have
nothing but good things to say about my experience at Impact today. Yeah the
food continues to be bad but that's beside the point. I attended 3 labs today.
The first
lab was about performance improvements in WebSphere Process Server. The lab
showed how to design the application and components within the application to
achieve greater performance. The take away points are:
-
Keep the BOs small because they are
serialized to and deserialized from xml. Also, for a long running process they
are persisted in the database. Finally, smaller BOs are easier to handle in the
mediation
-
Try to reduce number of interfaces.
Consider one interface with multiple methods instead of several interfaces with
one method. Do you have methods with similar signature? Consider consolidating
them
-
Finally, there are things you can do in
the application server to improve the performance
The
second lab Hacking 101, was an eye opener. It made me thinking, "may be I
should stop going online." On the application design side, it discussed
SQL injection, cross site scripting and more. The lab was very informative and
gave the audience great pointers on how to design the application with security
in mind.
The third
lab was about WAS clustering. It walked through the steps to create a vertical
and horizontal cluster and manage the web server and nodes from the deployment
manager. The lab was about clustering 101, which one could probably pick up
from an article or a redbook but I thought it was a good focused exercise.
On day 3,
I am going to attend some more technical sessions. Hopefully the lecture style
sessions won't be boring.
