A method of dynamic linkage including: receiving a request to launch a program; checking a system memory for the program; reserving a unique memory block of the system memory for the program and loading the program into the unique memory block if the program is not found in the memory of the system; performing internal memory relocations for the program if the program is not found in the memory of the system; ensuring that a library required by the program has been loaded into the system memory if the program is not found in the memory of the system; and invoking the program.

In an embodiment of the present invention the Java Virtual Machine (JVM) System Scope Initializer works on the premise of generating one JVM instance to be used by all processes system wide. An advantage in the present invention is that all processes that would normally otherwise have to instantiate a JVM, which can be on the order of millions of instructions (per process) can in large part be avoided realizing instead a tremendous system resource savings system wide. Another advantage can be that all processes that would normally otherwise have to instantiate a JVM, which can have a memory footprint on the order of megabytes (per process), can share the same memory view again realizing tremendous system resource savings system wide.
