Smooth WAS Install!

["John Taylor" <john.taylor@xxxxxxxxxxxxxxx>]

The last time I had WAS on the machine was at version 2.0, and after hearing
about the various horror stories with this application, I was expecting the
worst when I began installing version 3.5.3 this afternoon. Thankfully, the
process went without a hitch. Here are the basic steps that I followed:

1) install latest group PTF's for everything except WAS.
2) install WAS 3.5
3) install WAS group PTF - brings it up to 3.5.3.
4) install Admin console on W2K with SP2.
5) install Admin console fixpack to bring it up to 3.5.3.
6) set max# jobs for SQL server to *Nomax.
7) verified QEJB user's authority to CRTLIB (*use).
8) configure HTTP server for WAS & restart it.
9) start QEJBSBS & Admin console
10) start default_server application
11) Ran Hello World! servlet to verify installation.

There were several potential "gotchas" that could have made things much more
painful, but I was fortunate enough to find the following webpage, which has
a great section on installing WAS. It takes you through the process step by
step, in an easy to follow manner. Kudo's to whoever is responsible for this
great documentation:

http://www-1.ibm.com/servers/eserver/iseries/software/websphere/wsappserver/
docs/as400v35std/docs/indexiic.html

The next thing that surprised me was the performance of the software. It
wasn't nearly as bad as I'd expected it to be, based upon what I'd heard. My
hardware consists of the following:

AS/400
--------
9406-170 w/2385 CPU  (460 CPW)
1GB RAM
32GB non-raid  DASD (4 x 6713)
V4R5M0

Workstation
-------------
Intel PIII 933Mhz
384MB Ram
W2K w/SP2

Here are the initial startup times:

- start of QEJBSBS - 5 minutes
- start Admin console - 25 seconds
- start WAS default server - 60 seconds

Here's how long it takes to shut things down (with just a simple servlet):

- end default server - 4 seconds
- end QEJBSBS (using *CNTRLD 600) - 9 seconds

Here are the subsequent startup times:

- start of QEJBSBS - 1 minute, 6 seconds
- start Admin console - 20 seconds
- start WAS default server - 25 seconds

Overall, I'm quite pleased. It's too early to say what performance is going
to be like with a real web-app instead of a simple hello-world servlet, but
the initial numbers are encouraging.
