Alan,

Right.  The PROFILER.CDF data file is still in the Unidata-Wisconsin
datastream, BUT it is scheduled to be deleted on July 1.

If the file is coming in, then the problem has to be in the decoding of
the file into a McIDAS format.

Isn't hobbes an AIX machine?  What machine(s) are doing the data
decoding for your OS/2 machines?  If you are decoding files on your AIX
machine and then sharing the data files through NFS, then the problem
lies on your AIX box.  If you are sending the data along to the OS/2
machines and running the decoders there, then the problem is on your
OS/2 machine(s).  I'd ask Don about this, but he is not in the office
at the moment.

The FSL2 feed contains both the hourly summary and 6-minute FSL wind
profiler data in it.  These products are the replacement for the
PROFILER.CDF product (which is hourly summary data only) in the
Unidata-Wisonsin data feed.

>However, our pqact.conf on waldo

Right, it _will_ be going away.

>Can you briefly comment on changes in profiler data over the last
>year?

The FLS2 feed was made available a number of months ago and announced
to the members of the ldm-users, gembud, mcidas-x, and mcidas-os2
email lists.  At the time of the announcement we noted that sites
should transition to use of the FSL2 datastream since the profiler
data in the UW stream would be going away.

>Why is profiler.cdf still being created?

As an aid during users' transitions.

>Is it used by os2-mcidas?

McIDAS-OS2 does have the capability of decoding the PROFILER.CDF file
into a McIDAS MD file.  Don also added the capability of converting
the FSL2 data to MD files in the OS/2 XCD component.

>As to the new ldm and mcidasx on waldo, first, I have added FSL2 to the

Good.

Right.

>I made my

Actually, the profiler decoder for data in the FSL2 feed is the ldm-mcidas
decoder, proftomd.

>Also, the pqact.conf on waldo has the hourly
>summary profiler data from FSL2 uncommented.

Right.

>So, I am puzzled by the lack of profiler data on waldo; comments?

Me too.  I will get onto waldo and see if the products are, in fact,
getting to the machine.  If they are, then next step is to see why
proftomd is not converting them into McIDAS MD files.

>I note your changes and suggestion to eliminate /var/data/mcidasd.

Right.

>I don't have any explanation about the STRTABLE file being in
>/var/data/mcidasd.

The only thing I can think of is an errant REDIRECTion in a McIDAS-X
session.

>It may well have happened in our setting up the
>MCDATA environment.  I will check on that.

OK.  If it hasn't reappeared then the problem was transitory.  If it
reappears we need to find out how/why it is being created.
