Kenji,
>I installed McIDAS 7.705 on Sun Ultra 80 running Solaris 8.
Since 7.80 is now available, I recommend that you upgrade to it. One
big reason to do this is that the 7.80 version of the Unidata GUI
to McIDAS, MCGUI, has been converted to use of ADDE and it is where
I am concentrating interface development efforts in Unidata McIDAS.

When you say use the GUI, I will assume that you mean when you use MCGUI.
Please let me know if this is not the case (there is also a GUI from SSEC
that _is_ named GUI).

Both the SFCLIST and SFCPLOT commands use ADDE to get data. The 7.7x
version of MCGUI was not ADDEized; it got its data directly from locally
accessible data files.

This is saying that on one machine you have datasets setup/defined
or have run DATALOC commands (either directly or through a BATCH invocation
of one sort or another), and on the other machine you have not.
As a quick test, I checked to see if you have the ADDE remote server
setup on the machine you are running an LDM on: climate.geog.udel.edu:
telnet climate.geog.udel.edu 503
Trying 128.175.30.101...
Connected to climate.geog.udel.edu.
Escape character is '^]'.
This told me that something is listening on port 503, the port used
for compressed McIDAS data transfers.
Next, try to see if climate is setup to serve image data available in
the Unidata-Wisconsin (LDM feed type MCIDAS) datastream:
DATALOC ADD RTIMAGES climate.geog.udel.edu
DSINFO IMAGE RTIMAGES
Dataset Names of Type: IMAGE in Group: RTIMAGES
Name NumPos Content
------------ ------ --------------------------------------
ANTARCTIC 10 Antarctic IR Composite

DSINFO -- done
This tells me that the remote ADDE server is setup and runs. Next, I
wanted to see what, if any, image data you have in this dataset. To
test, I chose GOES-East IR images:
IMGLIST RTIMAGES/GE-IR.ALL
Image file directory listing for:RTIMAGES/GE-IR
Pos Satellite/ Date Time Center Band(s)
sensor Lat Lon
--- ------------- ------------ -------- ---- ---- ------------
1 G-8 IMG 20 SEP 01263 19:15:00 23 71 4

5 G-8 IMG 20 SEP 01263 13:15:00 23 71 4
6 G-8 IMG 20 SEP 01263 14:15:00 23 71 4
7 G-8 IMG 20 SEP 01263 15:15:00 23 71 4
8 G-8 IMG 20 SEP 01263 16:15:00 23 71 4
9 G-8 IMG 20 SEP 01263 17:15:00 23 71 4
10 G-8 IMG 20 SEP 01263 18:15:00 23 71 4
IMGLIST: done
This tells me three things:
o the ADDE server is setup correctly to serve this data
o you have been ingesting imagery from the Unidata-Wisconsin datastream
o you ingestion is behind
I offered the last observation based on the fact that the most recently
ingested GOES-East IR image was for 19:15 Z, and the time I ran this
was 22:08 Z. If your ingest were uptodate, you would have had goth
the 20:15 and 21:15 images in your set.
The next thing was to check what surface data you have:
DATALOC ADD RTPTSRC climate.geog.udel.edu
DSINFO POINT RTPTSRC
Dataset Names of Type: POINT in Group: RTPTSRC
Name NumPos Content
------------ ------ --------------------------------------
AIRCRAFT 10 Real-Time Aircraft data
FOUS14 10 Real-Time FOUS14 data
LIGHTNING 10 Real-Time Lightning data
PROF6MIN 10 Real-Time 6-Minute Profiler data
PROFHOURLY 10 Real-Time Hourly Profiler data
PTSRCS 100 All point data in MDXX files
SFCHOURLY 10 Real-Time SFC Hourly
SHIPBUOY 10 Real-Time Ship and Buoy data
SYNOPTIC 10 Real-Time SYNOPTIC data
UPPERMAND 10 Real-Time Upper Air (Mandatory)
UPPERSIG 10 Real-Time Upper Air (Significant)
DSINFO -- done
Finally, I tried the commands you listed above:
SF 1
ERASE
SFCPLOT T USA
This worked correctly.
SFCLIST NY
This also worked correctly.
What these tests mean is that climate is correctly setup to serve
at least the RTIMAGES and RTPTSRC datasets. So, suspecting that
your other machine is not setup, you could point it to use climate's
data through the remote server. Try the following from the 'other'
machine (assuming that it is not climate):
DATALOC ADD RTIMAGES CLIMATE.GEOG.UDEL.EDU
DATALOC ADD RTPTSRC CLIMATE.GEOG.UDEL.EDU
DATALOC ADD RTWXTEXT CLIMATE.GEOG.UDEL.EDU
DATALOC ADD RTGRIDS CLIMATE.GEOG.UDEL.EDU
and then retry the SFCPLOT and SFCLIST commands above.
>If
>you have any suggestions that I can look into, I would appreciate it.
I always hate to recommend for people to upgrade to new versions of
software, but in this case I think you would be much better off if you
did. After upgrading, I can work with you to get dataset definitions
setup on your machine(s) and also walk you through the newly revamped
MCGUI interface.
>Thank you for your assistance.
If there is anything I can do to help you get going on an upgrade, please
let me know.
