RE: keep a java program open

["David Morris" <David.Morris@xxxxxxxxxxxxx>]

Etienne,

I don't know if shared memory is available or not, but a user space
pretty much accomplishes the same thing and is an accepted
practice. Yes, I would send a short entry through the data queue
that identified the user space (tied to a session), offset, and size.
I have used qtemp for the user space, but beware if your code can
run in one of the server jobs like the database server, that qtemp
is cleared between calls even though activation groups are kept.

David,

What other options do you have for inter process communication on the
AS/400? In ILE C you can use shared memory, is that available in RPG?

Do you think that shared memory might be faster, all that you then
send
through the data queues are enough information to identify the shared
memory
that must be accessed by the receiving application.

Can the AS/400 Toolbox people please comment on the speed of accessing
data
queues from java using the toolbox classes.
