Question about MySQL timeout problem

Hi all,

After my app. Runs ok with Axis2 for a while, I get the following exception on Axis2 and Axis is stuck.
My app. Could not talk to Axis anymore. If I reboot Axis2, then everything works again.

I google this and found out most are reported by Hibernate users and their solutions.
How should I resolve this? Is there a setting for Axis2 I need to set.

Re: Question about MySQL timeout problem

Posted by Ted Zeng <ze...@adobe.com>.
Hi Paul,

Thanks for pointing this. I am new to this Pool connection concept.
I have used mysql before and never had this timeout problem as I always close the connection right away.

After googling a  couple of hours and I am still not sure how to set "testOnBorrow = true" in Axis.
I am using stand alone Axis2. Most pages talks about how to set it up in tomcat, etc.

So I set it like the following:
getConnection("jdbc:mysql://localhost:3306/AndroidAuto?autoReconnect=true&testOnBorrow=true")

In public class DBServiceLifeCycle implements ServiceLifeCycle's startup method.

Is this the correct way to set this up?

Thanks,

-ted

Hi Ted,
autoReconnect=true is not a proper solution: mysql close the connection if it was idle  for 2 hours. So if you access the closed connection you will have exception first and then auto reconnect, but
the original request will fail. You need to setup 'autoreconnect+connection test on borrow' at the pool level...

It looks like I fixed this problem with setting
autoReconnect=true
In DriverManager.getConnection() in the ServiceLifeCycle code.

I am using connection pool. I am pretty much following the Example code (DBService).
It seems the sample code should add "autoReconnect=true" to it. As the code stands now,
It should fail eventually when the database connection times out.

Thanks,
