What is an address space? An address space can be best compared to a
process in the distributed world. Instead of running processes, the z/OS
operating system uses a concept, called address spaces. Technically, an
address space is a range of virtual addresses, that the operating system
assigns to a user or separately running program, like the WebSphere
Application Server for z/OS. This area is available for executing instructions
and storing data.
During runtime each building block of an application server or a deployment
manager opens an address space, as seen in Figure 14-3.
