Welcome to the Burns iBlog!
Dear Mid Range Community,
My name is Christopher Burns and I'm the Director of Client Systems Modernization for GEMKO Information Group in Buffalo NY. I'm on a mission dedicated to educating the Mid Range community in two specific areas:
- Challenging mainstream attitudes and assumptions regarding iSeries Modernization techniques
- Educating iSeries professionals regarding "out of the box" methodologies and practices
This blog was created to facilitate the collaborative sharing of Mid Range expertise and ideas with all who hold a passion for this excellent technology. I invite you join and share your thoughts and questions with me and our vast Mid Range community.
Look forward to sharing with you - Christopher F Burns, Sr.

I'm not sure how to get this started but let me give this a try.
We have cut a new partition on our 870 to run Websphere to support the SSA Webtop application. The guidelines I found on the IBM site for system resources seem very inadequate for running this. Just starting up the server or web applications takes many minutes and pegs the CPU. I gave the partition .35 of a processor and 1Gig of memory (soon to be 3Gig).
What do you see people using to run Websphere?
Thanks

Recently there have been a number of product offerings from companies such as BCD, http://www.bcdsoftware.com/progenwebsmart.htm, for products that generate browser based front-ends to existing applications. Modernization seems to be equated with GUI interfaces. Is modernization just a "retty face" for green screen apps? Put on a GUI interface and the applications are now "modern"?
Chris, Fantastic idea. We all appreciate your dedication to the iSeries and your desire to collaborate with fellow iSeies diehards.
Doug,
We have customers using Websphere (mostly Express 6.0) for the following apps:
1. WebFacing
2. HATS/LE
3. A+ Commerce Catalog (an Infor/Daly.Commerce product)
None have home grown Java apps at this point
I don't think any of these customers (6 or 7 off the top of my head) have a dedicated partition for Websphere. They draw from the full resource pool and I know they spike during startup of the server, sometimes over 70%, so I can see why it would peg a partition with only 0.35 of a processor. But that's only startup, and it should smooth out after that.
As for startup time, I haven't seen a Websphere instance yet that didn't take 3-4 minutes to get its legs under it. Even the Power 5+ models seem to take at least 3 minutes before a webfaced app will respond correctly (with 4 gig of memory). Must be all that encapsulation and polymorphism going on. :-)
Nice to hear from one of my old Net.Data bretheren. Long live D2W.
Thanks Chris
If my end users thing it's to slow I'll bump up the CPU a little.
