Hi,

I am using JBoss version 4.0.4 GA for my test run with JDK 1.5.0.10.

I would like to understand the follownig - 

1) If i change the MaxPoolSize (Count of Server threads) attribute value of 
pooled invoker configuration from JMX console or twiddle - then what will be 
the impact mechanism of this change ?

a) Say for example i have initial value of MaxPoolSize as 50. I then decrease 
it to 70 how and  will JBoss behave internally ? 

- Will it change the threads to 70 immediately, even if say the workload would 
not require more threads or it will wait till the workload requires more 
threads and then increase the count to 70 in this case ?

- Essentially what policy or algorithm does the JBoss application server uses 
if any parameter changes at container level or web server level in 
configuration files through JMX or twiddle ?

a) Say for example i have initial value of MaxPoolSize as 50. I then decrease 
it to 30 how and  will JBoss behave internally ? 

- Will it change the threads to 70 immediately, even if say the workload would 
not require more threads or it will wait till the workload requires more 
threads and then increase the count to 70 in this case ?

if any parameter changes at container level or web server level in 
configuration files through JMX or twiddle ?


Please do respond to this as my tests are related to changing the parameters 
and their impact, hence its imperative to know what policy or algorithm does 
JBoss uses internally on any changes through JMX console or twiddle. If any 
more information on my environment is required, i would be glad to put that 
across.

Regards
Mahendra
