I realize that this might not directly apply to your "Oracle version: OLD"
situation, but maybe it's useful as a tool to convince others of the
benefits of an upgrade:
You can read more about how the Oracle VSS writer works at this link:
http://docs.oracle.com/cd/B28359_01/win.111/b32010/vss.htm
More info from the VMware side here:
http://blogs.vmware.com/vsphere/2013/03/quiescing-oracle-db-windows-vdpa.html
And from Microsoft, how VSS works:
http://technet.microsoft.com/en-us/library/cc785914(v=ws.10).aspx
If you can't leave "Oracle version: OLD" and Windows 2000, then I recommend
you use the VM tools on that guest to execute a scripted shutdown of your
application and the database in response to a VM tools snapshot request.
VM tools can also run scripts to start things back up when the snapshot
operation is complete. (deletion of snapshot after the backup does not
incur another shutdown). Depending on the speed of the computer, the
shutdown should only last as long as it takes to shutdown app, shutdown
Oracle, take snapshot, startup Oracle, startup app.
Good Luck!
