We've been using GENTRAN (which works fine-- the green screen
product), but GIS (the web/ifs/JAVA version) is 'interesting.'
When GIS works, it works fine. For routine application issues their
help desk is OK. When the issues is related to the iSeries...
My partner-in-crime has been dealing with GIS for upgrades. The
upgrade process in the iSeries does not run smoothly! From the
mumbling from his desk I know that working with their help desk is
not as nice as opening a ticket for iSeries issues. Now that IBM
owns GENTRAN/GIS, (and now that the service goes through IBM's
system) he's found that for issues with GIS and java and the IFS he
can at least open corresponding tickets on both the iSeries -and- GIS
sides and point them at each other. He had some luck getting the GIS
guy to listen to the iSeries guy about how the system works. And, we
got some of our java issues resolved as well!
The main problem with GIS is that they have 1 guy who knows about how
GIS works with the iSeries, but he's usually on vacation or out sick.
If you can catch him when he's available, he does know what's what!
Several years back (before the acquisition) we went around and around
with GIS because they swore up and down that the problem was caused
because the 'data base administrator' had not reorganized and
optimized the indices (and, I suppose, pruned and balanced the
B-trees). No matter how many times we explained, and forwarded them
copies of the IBM manuals, they could not get it through their heads
that the iSeries does all that stuff automatically!
Hopefully IBM can get some iSeries-knowledgeable people involved.

ps-- we suspect that there are about 3 companies running GIS on the iSeries...
