Hi Adrian,
I am facinng some serious connectin problems.
I have an j2ee appliction,
a.jar
b.war
the first two files are administrative consoles.
c.war
The c.war is a web application for the users. it has static pages, with very
few connection to the database.
I have an oracle-ds.xml with two datasources, the adminitrative console is
connection to the owner of the database, and the web-application to synomims.
the idea here is the web not to have access directly to the tables but in
synomims.
FIRST PROBLEM:
When the jboss is started up, i have a singleton class, caching ejbs, making
initialization some properites, also making a connections to the database: It's
executes some schedules task:
The error i get is the follwoing:
12037157 INFO 10 Jan 2005 23:04:28,401

I saw an previous topic of you saying that this is not an error , but a warning
thrown ?????
Althouhth of this error, u can work fine with the admistrative console..
2. Problem with the webapplication.
When the web-application is started up, alsoa servlet i runing , getting
the connectin for the datasource...
What is strange here, as i see from the logs, that the JBOSS creates 20
connection objects in the pool ? why is that ???
<web-pool-size>
<min-pool-size>5</min-pool-size>
<max-pool-size>20</max-pool-size>
20 is the maximum connection of the pool size ?
__________________________________________
<administrator pool-size>
<min-pool-size>5</min-pool-size>
<max-pool-size>100</max-pool-size>
So the application server creates 20 connection for the web-pool-size ?
why it doesnt creates also many connection for the administravice datasource.
???
I can not understand this.
PLEASE HELP.
I am using JBOSS 3.2.1
Is there a better connection pooling to 3.2.6 , can i move to 3.2.6 ??
ALSO THE CONNECTION FROM THE ORACLE SIDE ALLOWED ARE 115.
Thanx in advance...
