Virtual Box provides a facility of creating sharable VDI disks which can be mounted on multiple machines, but it doesn’t allow concurrent read/write access from multiple machines. If you are installing RAC database then its still achievable, because ASM will provide the feature of concurrent read/writes, but if you want to install a WebLogic cluster with High Availability the recommended approach would be to have a Shared Mount. Step to create a shared nfs mount is fairly simple. I am using a WD My Book Live, and will mount the Public folder as shared mount 1. Get the hostname/ip of the WD device. 2.
