What would you like to know ? Any specifics and you can ask in the WebSphere
newsgroup.
Yes, WebSphere is more than ready for production. In fact, you will find
some very innovative and some of the best clustering options with the
WebSphere solution.
I find the VAJ/WebSphere the fastest IDE based EJB development to deployment
solution in the marketplace. JBuilder 3.5/IAS probably comes a close second.
Others have their work cut out.
Cons .
- WebSphere is difficult to install for the first timer. You have to get the
fixpacks for OS/database correct. But if you follow the documentation then
you will have no problems. It is not a product to install by double clicking
setup.exe
- WebSphere uses an admin repository. Used for clustering, workload
management, http session clustering and failover etc. Currently this
database supports only DB2 and Oracle.
- WebSphere is only EJB 1.0 compliant now.
- WebSphere 3.0.2.1 uses IBM JDK 1.1.8. Current version is not Java2
compliant.
- IBM moves slowly. You will find that their cycle to get to new spec stuff
slower than other vendors.
Pros
- Clustering options are enormous and just beautiful. Models and clones make
clustering and horizontal/vertical scaling a snap and easy job.
- Wonderful proviso for persisting the HTTP Session object to the database
or to an EJB between calls. Imperative if your network dispatcher implements
a non-sticky affinity clause.
- Though some may see the use of IBM JDK 1.1.8 as a downside, the upside is
that this JDK is fast. IBM have made a lot of fixes for JDK to OS
performance and other issues. They have also back ported some of the stuff
from JDK 1.3 to here.
- I have not run any performance stuff, but I find WebSphere fast if not
faster than some of the other app servers.
- If you eval WebSphere, eval VAJ and WebSphere. Then you realise the true
power of the two. VAJ's bundled WebSphere test environment makes developing
EJBs very easy and very fast. The code/deploy/test/debug/recode cycle has
been brought down considerably.
- Being IBM, you get a lot bundled in and a lot of features in the whole
suite that you can add on. If you are interested in a 24x7x365 solution then
there are far too many features to explain here that are present in the
package.
- Probably the best legacy connectivity solutions at the moment to IMS,
CICS, AS/400 etc. (Understandable, I guess.)
- EJB support is very good. I have had no problems so far with both SSB's
and EB's.
- Has got a decent administration client and is Tivoli enabled.
- It is very well documented. I have now rebooks and redpieces flowing out
at a rate faster than I can consume.
