This error happens when there are too many connections opened. There are too
many connections opened because before you shut down your application, you
don't explicitly close

I thought Oracle fixed that bug in their connectionPooling driver back
in 2001. Am I missing something? Are you using some other driver to
create a pool of jdbc connections to Oracle? sorry for the question if
it's already been answered

Yoav is correct, you should be using the newer driver and not the
older one. good thing I asked which version the driver is.
that's a really old bug in the old driver. I remember reporting the
bug
Perhaps your application is hanging on to the database connections and not returning
them to the pool?

just in case, here's a link to Oracle's developer jdbc section
http://www.oracle.com/technology/sample_code/tech/java/sqlj_jdbc/files/jdbc30/index.html
just make sure the apps are calling java.sql.Connection.close() when
they are done. the PooledConnection underneath will pass the
connection
in that section so the connection never got closed.
Once I put a finally block in with a con.close() then it solved my problem.

Hi,
Hmm ;) There's a good reason there's no close method on
javax.sql.DataSource. There's also a good reason the J2EE spec calls for
the container, not the user, to manage the lifecycle of JNDI resources

maxActive :20

maxWait :1
removeAbandoned :true -- what exactly is MaxIdle parameter
Can someone please suggest how to achieve connection Pooling in tomcat 4.1.
As per the docs i have
1) configured server.xml to include the resource parameters ( datasource,
connection pool size etc)
2) In application code , retrieve connection using datasource
3) Every Method call to database
Shilpa,
What OS are you running this configuration on? If it is AIX I would investigate to
see how the system is configured for the number of processes per user on the system.
If it is configured as a Workstation it is defaulted to 128 processes / login. If it
is configured as a server it
If you want to use dbcp send me a mail. I had bad days trying to
configure it, but it's working, I can send you my configuration (using
pgSQL)

I see you guys are talking about connection pooling in Tomcat. I presume
you must be referring to HTTP connection pooling or something? Is there a
dB connection pooling resource in Tomcat? Something like Poolman?
I know this is somewhat off topic but your thread reminded me to ask.
Thanks.
Hi
Does that mean i can create an Instance of
AS400JDBCConnectionPool class and keep it is servlet
context and then all the servlets can have access to
it??

You can use JNDI to allow for sharing of connections across servlets
using either the built in pool (dbcp) or your own pool.
For Tomcat 4.0.x, you can look here (about half way down)
