Isolating resource use for applications and users
The following example describes a situation where a system
administrator needs to isolate an application in order to ensure
dedicated memory and CPU cycles.
A system administrator has determined that his company’s credit card
purchase system needs dedicated memory and CPU resources for users
who are buying products. To ensure the buyers dedicated CPU cycles, the
system administrator creates a PSET PRM group for buyers and assigns
one of the system’s four cores to the group. This guarantees the CPU
cycles will be available to buyers as needed. In addition, the system
administrator chooses the memory isolation option to prevent memory
shares from being loaned out or borrowed from other groups. This
ensures immediate response time, rather than waiting for borrowed
memory to be paged back in.
