What is VRP
Virtual Resource Partitioning (also known as VRP) is a virtualization technology that allows to allocated computerized resources (such as CPU & IO) to transactions. Unlike conventional virtualization technologies (such as those that are used by Vmware that allocates resources per operating system (windows,Linux...), the VRP technology is working 2 level deeper while allowing to regulate and control the amount of resources that are used by specific transactions within the application. VRP technology is used to give more (or less) resources to applicative transaction and by that, boost it (or slow it down).
VRP technology overview
VRP is usualy implemented at the Operating system in a way that is completely transparent to the application or transaction. The technology creates virtual resource lanes and redirects specific transactions to those lanes allowing them to take more or less resources according to the lane definition.
VRP technology can be implemented in any Operating system. Existing vendors in the market applied it on most of the Open operating system such as Windows, Redhat, Suse, HPUX, Solaris, tru64, AIX and others.
