Hi, If it helps to put things in perspective, MDB is the J2EE implementation of MOM (Message oriented Middleware). In messaging systems, 2 or more applications exchange information in forms of messages asynchronously. In this scenario, a message is a self contained unit of data and/or routhing headers.
In your case (as I understand) Unix crons are running asynchronously, but there are no interchange of messaging between applications that fire or use the crons. They simply just get alive at a particular specified time and complete their designated tasks. Additions/Corrections Welcome. Thanks, Nitin Milind Kulkarni wrote:
Hi All, We are developing a several batch programs. The batch programs are invoked using Unix CRON job at a specified time. Somebody told us that it would be better if we can use MDB. I have the following questions in this regard: 1. Will we still need Unix CRONs to invoke batch program if we decide to use MDBs? If no, how we can schedule batches using MDB? 2. What are the real advantages of using MDB over CRON?
