VMware clone - Oracle (parent)

Hi,

Suppose I create a parent VM with Oracle 11g installed in it. Parent OS: Windows 2003, computer-name: A

Next, I create a clone (one or more) of this parent-VM, and I give this clone computer-name: B.

On starting this clone-VM, I get an error related to oracle db control starting. This is because the Oracle was installed in parent-VM and uses computer-name: A in different config files.

My question is: how can I use Oracle in different clones without having to reconfigure Oracle in each clone manually?

Thanks.
