Patrick,

Have you tried the OpenSource WebSphere Tools available at Ignite/400?
They provide some OS/400 commands for performing the actions you talk
about.  Generally, they perform about the same as using the Admin console,
however, since they are commands you can run them in batch jobs on a
schedule instead of doing it interactively.

http://www.ignite400.org/html/opensource/index.htm

While I personally prefer to run WebSpere on an AS/400 because I think it
is easier to manage it, running it on a Windows 2000 or Linux server
yields excellent performance.  I guess if you had a slow or congested
network that might not be the case, but generally I think you get great
results from the Toolbox JDBC driver.

Also, I would highly recommend WAS 4.  I find it performs a lot better
than 3.5 especially in the area of starting/stopping and management in
general.  Perhaps the newer 3.5 service packs have some of this as well.
3.5.3 is pretty old now.

Hope this helps.

About a year ago there was a discussion going on about running WebSphere
on NT or AS/400.  The AS/400 was the way to go... so we did.

Currently we have
        an AS400 model 9406-720
        with 2Gb of memory
        with 75Gb Disk (65% to 70% used)
Running WebSphere V3.5.3 SE
Running 6 Domino Servers
Running Native Bussiness apps
used for development by our developer team

Our experience is:
- WAS is running well in normal situations
- Performanceproblems occur when deploying webapps to WAS.
- The first load of WAS-console takes about 2 minutes but when we
stop/start WebApps or Server or QEJBSBS or add new servlet, it can take
about half an hour before the task is done!

Now the time has come to start using WebSphere Studio.  Deploying seems to
be impossible too for which we suspect performance issues.  Finally we
asked for support.  They countered same problems and tried to get an
in-depth-look after which we were advised to load WebSphere on an
NT-server...

1) Any suggestions welcome
2) L2 cache an AS400: I know L2 cache on PC but can't find any reference
on AS400.  How to check - order - install it?
3) What about performance ?  Because WAS is not 'on' the AS400 but on a
PC, data has to be retrieved from the AS400...
