RE: Java versus RPG on iSeries

Joe,

We support one of our manufacturing plants with a
Java/RSSQL/SQL Server/Oracle/iSeries based system. The iSeries
system collects orders and manages finished good inventory.
The Oracle database handles raw materials, scheduling, and
reporting, RSSQL supports about 300 PLC devices that provide process
feedback, and SQL Server is used by some of the materials handing
equipment. All of this runs 24/7 363 days a year. Java was
used because it integrates better than anything else we could
find.

Response is good, but this doesn't quite meet your criteria because
none of the database tables involved in this process have more than
about 2 million records.

Really?  What J2EE-based application suite did you find that
outperforms
RPG-based ERP systems?  I've done a bunch of research on this, and I'm
seriously interested in hearing about a J2EE solution that can perform
MRP
generations on databases with tens of millions of records.  I have yet
to
see one in production.

All the J2EE applications I've seen sort of dwindle away at the CRM or
SCM
level, and never really make it into the manufacturing side of the
shop.
They can handle customer order entry and fulfillment, but shop floor
control
and material requirements planning seem to be beyond the capabilities
of
most J2EE packages.  However, if a pure J2EE MRP/SFC package exists,
it
would be an excellent candidate for deployment on the iSeries.
