[McIDAS #FTB-213912]: Image Display Issue, MCIDASx2007c on AIX

Hi Martha,

re:

No worries.

re: was v2007c the first v2007 install on your AIX machine

OK.

OK.  Since you are able to display images from a remote ADDE server
(one of the tests I asked you to run yesterday), I would say that
the problems you are seeing when running the test procedures are
related to the setup to run the tests only.  Given this, I recommend
that you go ahead and finish the installation of v2007, and then
see if you have any problems.

This _is_ strange alright, but the fact that you can display images
from a remote ADDE server tells me that the image subsystem is working
correctly in the new build.

I have no explanation for the problems you are seeing in running the
tests, but I am betting that it is related to the environment that
was setup before running the tests.  Since the image display subsystem
is working correctly, and IF you can also put a map on top of an image
displayed off a remote ADDE server, then I think you are safe in proceeding
with the McIDAS v2007 installation.

re:

Very good.

re: We also can no longer display the ADDE datasets on the AIX box from
other systems.  I did cut over to the 2007 version of mcadde but it
did not help.

I am not sure what you mean by cutting over to the v2007 for mcadde.
If your system is setup per Unidata instructions, then this would mean
that you went ahead and finished the installation in the 'mcidas' account.
Is this the case?

re: displaying an image off of a remote ADDE server

This sounds like the same thing my attached image showed.  The sector
I asked you to display is centered on 0N, 72W.  It is a composite of
GOES-East and GOES-South (GOES-10).

OK, I understand now.

Questions:

- did you, in fact, finish the v2007 installation in the 'mcidas' account
  on the AIX machine?  I am assuming that this is what you meant by
  cutting over to v2007 for 'mcadde'

- as a checkpoint, please send the output of the following in the Unix
  login before you run a McIDAS session as 'mcidas':

env | grep ^MC

  cd $MCDATA
  dsserve.k LIST

Cheers,

Tom
