Hi,
i have succeeded in setting up nginx (currently 1.1.0) for load
balancing 2
backends running the Oracle forms 11g application. Additionally, i’ve
set up
nginx with the jvmRoute module to have session stickyness within the
java
session.
The bad part: the application’s performance is unusable slow. Is there
any
way to speed up the performance? Are there modules i should use when
load
balancing a java application?
Load balancing other stuff, like a webpage works pretty good. Even with
the
jvmRoute module used for session stickyness. No performance issues at
all.
I’d appreciate any help. Thanks in advance!
Kind regards,
DJ

How do you measure the performance or how do you decide it is slow?
Does the ‘Oracle forms 11g application’ in standalone mode work faster
than in combination with nginx?
In short lets say if the application can handle 1 request per second
then balancing 2 backends won’t magically make more requests
per second possible than two. If you can’t speed the application nginx
can’t solve it for you other ways than introducing more
backends to loadbalance or caching the responses (proxy/fastcgi cache)
to avoid hitting the backend at all.
Of course if each app can handle 1000 requests and with the balancing
suddenly it drops down to 100 there is some bottleneck. But
for starters at least your nginx config would be needed.

Hi,
well, the application runs quite good in standalone mode. Ofcourse, i
know
that java is not a performance monster.
But speaking in bad performance, it takes about 5 minutes to log in,
clicking too much on the app window may result in a never ending
sandbox,
when the app is finally open, and i choose an option it takes minutes to
respond. That’s what i’m calling the bad performance 
It’s really unusable slow.
