Subject RE: Tomcat on a Linux virtual machine
Date Mon, 18 Apr 2011 12:51:36 GMT
We're Apache->Tomcat->MySQL all in separate Cent-OS VM's with no
problems.  It wouldn't be Tomcat anyway, right?  One might say that
something is up with the drivers used by the connection pool, but,
that's still not Tomcat, and to be accurate, the driver used by Tomcat
or an app inside Tomcat doesn't know squat about the DB being inside or
outside of a VM.

So, I'd focus entirely on the DB config and its environment.

Do you have a spare machine where you can setup a Tomcat/Postgres pair
outside of a VM?

Subject: Tomcat on a Linux virtual machine

I have an application (commercial) running on a virtual instance of
Linux talking to a Postgres database.
We are continually getting locks on the DB that are crashing the app.
I think it's just bad programming on the suppliers side, but the
supplier has latched onto the idea that it is because it is running on a
virtual machine.
Has any experienced any problems running Tomcat on a virtual machine
similar to this?
