Loading Protected Address Spaces
Even if an NLM is designed to be loaded only once, you can load multiple
copies of the NLM on your server if you load them into different address
spaces.
When you load modules into a protected address space, NetWare assigns
whatever amount of memory the loaded modules need, up to a maximum
size of 512 MB. The maximum size of a protected address space is fixed;
but within that maximum limit, the memory size of the space grows and
shrinks as needed by the modules in the address space.
If you want the server to clean up address spaces that abend, make sure
the Memory Protection Fault Cleanup parameter (Memory category) is
set to the default setting of On. If an address space abends, the server
removes the address space and its modules and returns the resources to
the system.
If the Memory Protection Fault Cleanup parameter is set to Off, the
situation is left to the abend recovery mechanism.
You can create a protected address space when you load one or more modules.
To load protected address spaces, use the commands in the following table at
the System Console prompt or in NetWare Remote Manager on the Address
Space Information page (access by clicking Protected Memory link in the
navigation frame).
