GOAL:
2 gigabyte memory limitation per process on Windows platform
FACT(s) (Environment):
Windows NT 32 Intel/Windows 2000
Windows 2000 Advanced Server
FIX:
By default, Windows based operating systems have a limit of 2GB of address space per process. With Windows 2000 Advanced Server and Data Center Server, Microsoft uses Intel PAE technology to overcome these limitations.
The switches are: /3GB, /PAE and /AWE
/3GB allows up to 3 gigabytes of address space but only for executables that have been built for it. /PAE is the ability of the IA 32 processor to address more than 4GB of physical memory. The AWE API's allow a program to remap pieces of its 32-bit address space over larger amounts of memory.
Progress does not currently work with these switches and API·s. They will not help to overcome the 2GB memory limitation per process on Windows platforms.
