I think we answered this on internal email thread but to summarize
SC can backup Oracle or any DB it supports running in a VM guest with RDMs. As long as the App data is separate from VM itself. SC has no way to quiesce VMware ie: do a vmware snapshot.
You could additionaly do an FS flush in SC but you need to provide the command
examples for unix are "sync" command
and windows has a tool called SysInternals sync.exe
