Hi Gilbert,

OK.  Presumably you mean you added the new products to the McIDAS
routing table?

Why did you run these two commands?  These setup XCD decoding of LDM
ingested conventional data.  They have nothing to do with the decoding
of Unidata-Wisconsin (IDD UNIWISC aka MCIDAS) data.

>Hmmm. What am I doing wrong?

When setting up XCD decoding, you have to define XCDDATA as the
directory where the XCD decoders create their output.  For instance, if
you were decoding into /data/ldm/mcidas, then you would do the
following in the 'mcidas' account to setup XCD decoding:

<login as 'mcidas'>
cd workdata
cp ~mcidas/data/SCHEMA /data/ldm/mcidas
cp ~mcidas/data/SYSKEY.TAB /data/ldm/mcidas
cp ROUTE.SYS /data/ldm/mcidas
te.k XCDDATA \"/data/ldm/mcidas
batch.k XCD.BAT
batch.k XCDDEC.BAT

OK, sounds good.

Yes, but the machine in Rio doesn't have SCSI disks either.  As an
update, the same machine in Rio was upgraded to an AMD 2800+ processor,
and its system disk (as opposed to RAID disks) was upgraded from a 40
GB ATA-100 to an 80 GB ATA-133.  I built McIDAS on the new
configuration, and that build took all of 5:07.  Yet another new speed
record for that box!

As a comparison, I did the same build on a dual AMD 2600+ machine that
has an ATA-133 80 GB system disk here at the UPC, and that build took
around 8 minutes, but the system was ingesting all IDD feeds as part of
its stress testing.
