Re: keep a java program open

Hello Etienne,

A user space is effectively shared memory -- just implemented as an
external object.  However, there was a discussion a while ago on RPG400-L
about accessing teraspace storage from RPG.  I proved that was possible
from RPG IV.  Since the Shared Memory APIs (described in the Unix API
manual) use teraspace I should think it would be possible to use shared
memory from RPG.  You would need to prototype the APIs but I would expect
it to work.

Using a user space is probably easier and more obvious to most AS/400
programmers.  A user space is limited to 16MB but teraspace gives you
access to bloody big gobs (that's a technical term) of storage.

Regards,
Simon Coulter.
