Anybody wants to comment? OS390/UNIX (old name Open Edition MVS).
IBM has something called OS390/UNIX (old name Open Edition MVS). This thing exist for the last
3-4 years but it was not yet in stable shape. So , IBM customers (all this huge banks, insurance
companies,etc,etc) did not go for it and were waiting.
This OS390/UNIX thing is a very powerfull thing designed
to take part of the market from the native UNIX (read SUNW)
applications.
There is a lot of good software written to be run on UNIX platform. Any time you would want this
software to run on IBM mainframe, you basically would have to redesign everything. I know about it
because my job is to port UNIX aplication and make it run on Mainframe. This is almost like writing
things from scrach. Even when the environment where it runs (file structure,etc, etc, is very
unsofisticated).
So that is what in the past precluded the applications written for UNIX to run on Mainframe.
With OS390/UNIX this problem little by little goes away.
Because it is a UNIX environment, so that opens the door to applications written to be run on UNIX
machines to run on
mainframe. While there still are problems, it is true that
big companies started to move little by little in this direction by educating their technical resources,
etc,etc,,,. While things do go slow in Mainframe world once they start moving it is like a cho-choo train,
it keeps going and it is difficult to stop. I am not saying that tomorrow all mainrame sites will be running
UNIX application , but the movement in this direction is definitely there.
I also have SUNW long and just hope that there will be plenty of space left for SUNW to grow. |
