Hi
I might be working with Dynamo soon, so can anyone give me the 3 line version on why Dynamo is 'bad'. I just get the feeling its less prefered and I'm not quite sure why or what the issues to consider would be. I'm assuming Websphere is almost an industry favorite.
Another way to ask the question is "what makes a good application server"?
(except for the obvious ones like performance and stability, but feel free to mention perfomance data etc.)
Thanks.

Hi Jim,
Well, I'm sure you could have found most of the information yourself with G**gle but AFAIK:
- ATG has discontinued Dynamo Application Server in favor of IBM Websphere.
- JHTML, ATG's server-side scripting language has been deprecated in favor of JSP
- Their portal technology is not (yet) based on the Portal specification (JSR 168)
- Their portal framework is not compatible with Struts (Websphere is).
- ATG being a small player on the market means there is a lack of IDE integration (Borland, Eclipse, Netbeans, IDEA and others not not support it)
- Most classes in a web applications need to be on the global system classpath => i.e. redeployment of an application often means stop and restart the server
Hope this helps,

I read an article, it said ATG Dynamo was good, but did not follow the standards.

Regarding the "industry favorite" notion, I have to note that WebSphere and WebLogic are very even in market share (besides, who knows how the vendors come up with their calculations...) but there are certain trends in particular industries. For example, WebSphere dominates financial institutions mainly because their collaboration with these organisations goes way back to mainframes, CICS and all that.

Yes I guess I could, but it would take me quite some time to get a feel for for it. I was sure that I could find a good developer perspective here, but you gave me the five line version instead of the three line one. Exactly what I was looking for though.

This sounds quite serious. I looked around a bit - are you sure they explicitly discontinued it? It seems like they are extending support their suite to work with websphere, but point taken if only that is the case.
Thanks.

The only taste of success some people get is to take a bite out of you. Or this tiny ad:
