Oracle Database on VirtualBox not closing connections

[grayjoc]

I've installed the Oracle "Developer Day" image (Oracle Linux 5 and Oracle Database 11g EE) onto VirtualBox 4.2.16 running on Windows 7 host.

use this as a database against which to run integration tests. Multiple tests are run against a Java application (the tests are run on the host) which connects to the Oracle DB on the guest.

The problem is after running the suite of integration tests all of the connections to the database appear to remain open. This problem doesn't occur with existing installs of Oracle (either remote or local to my host PC).

Can anyone advise on the best way to investigate whether VirtualBox is causing this issue or not?

Are you using NAT mode? if so, switch to host-only or bridged.

Else, please read Minimum information needed for assistance to provide a VM log file as well as the guest settings.

Thanks! I switched to using "Host-only" networking and everything is now working as expected.
