I've actually put up two of these LPARs now. Normally,
I mostly write code, but I've been asked to do a bit
of admin work too. Having a good time with it...
The iSeries (aka AS400) has actually come a long way.
It has been interesting watching it morph from S/3 to
S/34, S/36, S/38 up through the present. The amount of
language support/tools is very good now.
Aside, from LPARs, the AS400 now has an integrated file
system (IFS) and a built-in shell. Most of IBM's middle-
ware (e.g. WebSphere) is implemented in Unix form on the
IFS. There are a lot of integration bugs between the IFS
and the rest of the system and the shell is very limited
at present.
Thus, the Linux LPAR is a good move because I can implement
Java code there and have it talk to DB2 on the native OS
(inter-LPAR connection). This is what I'm working on now.
