Hsie,

re: willingness to serve McIDAS data on stratus by ADDE

>I would like to.  Before we proceed, could you try to get data from 
>stratus.al.noaa.gov.  ADDE server is running on that machine.  If you can, 
>please let me know.

From my McIDAS session here at Unidata I "pointed" at stratus for the
major McIDAS ADDE datasets:

DATALOC ADD CIMSS STRATUS.AL.NOAA.GOV
DATALOC ADD RTGRIDS STRATUS.AL.NOAA.GOV
DATALOC ADD RTIMAGES STRATUS.AL.NOAA.GOV
DATALOC ADD RTNEXRAD STRATUS.AL.NOAA.GOV
DATALOC ADD RTPTSRC STRATUS.AL.NOAA.GOV
DATALOC ADD RTWXTEXT STRATUS.AL.NOAA.GOV

I then did several lists and plots of data that were all successful:

Everything I tried worked nicely, so it looks like you are good to go.

>Then I will set that machine up for community ADDE server.

Sounds great.  Thanks!

I would like to announce that stratus will serve:

CIMSS
RTGRIDS
RTIMAGES
RTNEXRAD
RTPTSRC
RTWXTEXT

This is almost the same set of data that the other sites will be serving,
but they have access to the GINI imagery in NOAAPORT.  Does stratus
have the bandwidth/disk space to get and serve the GINI data?  The volume
is over 200 MB per hour, so the bandwidth and disk space needed is
considerable.

To make things easier for client users, I do the following:

1) create an ADDEINFO dataset on the server:

cd ~mcidas/workdata
<edit RESOLV.SRV and add the line:

N1=ADDEINFO,N2=DATASETS,TYPE=TEXT,RT=N,K=OBTX,Q=/home/mcidas/workdata/DATASETS,C=DATALOC
 commands for adde.ucar.edu Datasets,

 ** note that this is a single line and that the trailing comma is important **

2) create a file called DATASETS in ~mcidas/workdata

----- <snip> -----

REM ? DATASETS - Define ADDE datasets served by this host
REM ?
REM ? File:    DATASETS

REM ? Purpose: Define ADDE-served datasets for the workstation.

----- <snip> -----

If you have the BLIZZARD dataset (the McIDAS Learing Guide training dataset
which I did not find) installed and accessible on your machine we could
add that to the list that will be served (amounts to changing the
announcement and the DATALOC ADD BLIZZARD line near the end of DATASETS.
If you want to serve this, then you would need to:

o decide on a directory that the remote server has access to that
  won't be scoured and install the data there:

cd whatever_directory
ftp ftp.unidata.ucar.edu
  <user> umcidas
  <pass> XXXXXX
  cd data/tutorial
  binary
  get learn.tar.Z
  quit
zcat learn.tar.Z | tar xvf -
rm learn.tar.Z

o make sure that the REDIRECTions defined for your 'mcidas' user can find
  those files:

cd ~mcidas/workdata
redirect.k ADD AREA8\* \"/whatever_directory
redirect.k ADD MDXX8\* \"/whatever_directory
redirect.k ADD GRID8\* \"/whatever_directory

  The other way of doing this is to edit the ~mcidas/workdata/LWPATH.NAM
  file directly.  If you decide to do this, you must make sure that there
  are no active McIDAS sessions that may alter the REDIRECTions.  Since
  you are running XCD, it is probably safest to issue the redirect.k
  statements directly.

>Right now I do not have any restriction on that machine over mcserv.

Opening up your server to ADDE users will be provide a very nice service
to our community.  I don't think that you will see an unreasonable amount
of traffic on your server.  My intention is to identify a number of sites
that are willing to help out.  This will have the effect of load leveling
on any one particular machine.  This will be especially true when we
install a well configured machine at SSEC (a Sun Enterprise 450 with 
1 TB of disk; this is even more of a machine than motherlode!)  This
box will not only serve the various McIDAS datasets, but it will also
host DODS services and give the Unidata community access to high
resolution GOES imagery in its original state (not remapped; not resolution
reduced).

Thanks for helping out with this community effort!
