5.4.1 WSRM description
Is very common that customers run multiple production applications on one
server. These applications often compete for system resources, such as
processor and memory. When competition is highest among applications (during
peak periods, for example), the applications that need, for business reasons, to
have the most resources available to them often do not get this allocation, and
performance suffers. Also older applications might have the tendency not to
release the resources they have been using after they have finished completing
their tasks. Applications causing memory leaks also present significant problems
to the function of the system, and to other applications that are installed.
All of these circumstances can cause the application or the operating system to
become unstable. WSRM helps avoid these situations by specifically allocating
and managing resources to applications, processes, and services, thereby
restricting the applications from consuming more resources than they have
otherwise been allocated. These are some environments of use:
Consolidate applications from several servers.
Improve server hardware utilization.
Fair use of resources.
Limit resource-intensive applications.
Figure 5-13 on page 198 shows the main window of WSRM.
