[LDM #GJO-292105]: LDM Couldn't Exec Decoders Error

Chris,

> I checked the path for LDM, root, and Gempak, they all contain the path to
> the decoders: /home/gempak/GEMPAK6.2.0/os/linux64/bin
> Sorry, I should have been more clear with the NAWIPS/os/linux64/bin
> reference. NAWIPS is the soft link to GEMPAK6.2.0 in the /home/gempak
> directory.
> There is also a soft link for /home/ldm/decoders:  decoders ->

Your pqact(1)) configuration-file entry

WMO ^U[ABCDEFGHIJKLMNPQRSTWXY]
PIPE decoders/dcuair -b 24 -m 16
-d data/gempak/logs/dcuair.log
-e GEMTBL=/home/gempak/GEMPAK6.2.0/gempak/tables
-s snstns.tbl
data/gempak/upperair/YYYYMMDD_upa.gem

invokes the decoder "decoders/dcuair". In order for the pqact(1) process to 
find the "decoders" directory, the PATH environment variable of the LDM user 
would have to contain the pathname "/home/ldm" or "." (it has neither). You can 
either replace "/home/ldm/decoders in the LDM user's PATH with "/home/ldm" and 
execute the command "ldmadmin restart", or remove "decoders/" from all the 
pqact(1) configuration-file entries and execute the command "ldmadmin pqactHUP".

Regards,
Steve Emmerson
