OK, so I've been asked to do some research for a project here to develop an
architecture for a client.
The idea is that we're developing a replacement for a legacy system that
sits between the clients internal systems (ordering, support tracking, etc)
using IBM's MQSeries messaging software to talk to the tier that we're
architecting, which talks on the other side with an EDI mapping software to
map the messages sent from this tier to EDI docs to send out to the
customers/suppliers/etc on the outside. The tier we're building and the EDI
mapper tier currently send EDI docs back and forth, but this is very
flexible and open to change.
They want to do this on Intel boxes, and although the main focus was/is NT,
I've been asked to develop an overview of how this architecture could be
built on Linux on Intel, including failover, load balancing, etc. It would
be running Oracle8i for storage, etc, although the records are rountinely
moved off onto an archive data warehouse for data mining, etc.
I'm looking at Java middleware for message servers, business logic, talking
to the database (especially since Oracle8i has so much java already in it),
etc., but would be interested in any suggestions for any part of this
architecture. I'm currently looking at Bea Weblogic and IBM Websphere for
this tier. I'm hoping someone here has combined one or both of these with
MQSeries, using EJB's for the business rules and using either a direct link
to MQSeries or some type of JMS provider to be able to talk seamlessly. Both
of these products seem to handle the services needed, including failover /
load balancing, Oracle connectivity, security, connections to messaging
middleware, and availability on Linux, so any other products will need to
support these as well, or plug in with other products to provide these
services. This tier needs to process about 25K messages / day, and be
rock-solid.
Thanks in advance for any suggestions or comments!
