Subject a question regarding maxActive
Date Wed, 02 Sep 2009 03:54:29 GMT
Hi, experts

I have one java web application. In the application,
several datasource was configured for dbcp. For each datasource,
maxActive was set to 100 and max Idle set to 30.

Then I used
several crawlers to make the web application very busy, until the
application reported that it can't get an idle connection to the
database server. 

But strangely enough, I found the connections to database servers was only about 100 using
the nestat -an command. 

my question is : is the maxActive shared by the whole applications ? In
my opinion, the max connection should be the number of datasource times
maxActive.  For example, 4 datasources, the connections should be 400,
not 100. 

How about different jvm on the same machine?
