How to increase default work manager threads

The default workmanager, as its name tells, is the workmanager defined by default.

Thus, all applications deployed on WLS will use it.

The default workmanager belongs to a threadpool.

As the initial threadpool comes with only five threads, that's not much.

If your application has to face a large number of hits, you may want to start 
with more than that. 


Well, that's quite easy. You've got two ways to do so.

1) Modifying the config.xml

Just add the following line(s) in your server definition :

<server>

<name>AdminServer</name>

<self-tuning-thread-pool-size-min>100</self-tuning-thread-pool-size-min>

<self-tuning-thread-pool-size-max>200</self-tuning-thread-pool-size-max>

[...]

</server>

2) Adding some JVM parameters

 Personally, that's my favorite option since I don't like when people go 
in a generated config file

and mess up with tags. If you're sure of what you're doing, 
that's ok, but it's safer the following way :

add the following option in your command line : 
-Dweblogic.threadpool.MinPoolSize=100

Observing the result
