New objects are always created in heap space and the references to this objects are stored in stack memory. These objects have global access and can be accessed from anywhere in the application.
What is the importance of memory allocation?

When the Equal_Per_Session resource allocation policy is managing the system, resources are allocated on an equal basis for each session connected to the system.
When to use equal per session resource allocation policy?
This policy is especially useful for application servers. When the Equal_Per_Session resource allocation policy is managing the system, resources are allocated on an equal basis for each session connected to the system. This policy is for use with RD Session Host servers.
