RE: Passing Java Object to iSeries

Out of curiosity, could you modify the Java app so that it re-uses the
same connection over and over rather than open 4000? Maybe you already
thought of that, and there is a design reason why this isn't possible
(if so, what is it?) but opening and closing connections are very
expensive operations. The more you can re-use a single connection the
better.

Subject: Passing Java Object to iSeries

So I was thinking...
 
We have this Java app that runs on a WinTel box but gets it's data from
the iSeries.  Once all of the data has been mangled, massaged, twisted
and bent to fit into the format we need, it is then piped back into a
set of tables on the iSeries.  One of the problems is that during the
process of putting the data back on the iSeries, the application opens
around 4000 JDBC connections.  While this method works, it is somewhat
slow.  
 
What I would like to do is pass the objects that have been created by
the Java app back to the iSeries and let "something" deserialize them on
the iSeries side and stuff the data into the tables.  This would
eliminate all of the JDBC connections that are currently part of the
app.  I could open one connection, loop over my stuff, have "something"
on the other side deserialize each object and finally close the
connection.
 
I'm not familiar with what can be done on the "other side".  Could RPG,
CL, xxx be the "something"?
 
Thanks,
Kelly
