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. Joe
