Taking part in Oracle's open-source technology day, I have no contact with Oracle db and open-source. I have always been a fan of ms products and cisco, but I am free of charge to learn more, it is also good to broaden your knowledge. In Oracle's Linux policy, the platform uses a complete copy of rhel (they vp spoke out of logo and brand, everything), but added the Oracle Linux management package and Oracle

Xen is the new virtualization kid on the block. It's gaining visibility and importance at a, only projects such as Linux and Apache has seen before. Xen have been around for a couple of Years:it is originally part of the Xenoserver platform, which aimed to build a publi C Infrastructure for Wide-area distributed computing.

local disk, and how to simulate it?This requires the creation of a local loopback device on the real hard disk, a part of the hard disk space, the creation of a local loopback device, while the device is in the form of a file and associated with the virtual disk of VMware Workstation. When a virtual machine stores data in a virtual disk, VMware Workstation is required to store its data in a local real file. Obviously, the disk performance of the virtual machine is not as good as the local real
