Hi Gerry,

It sounds like you should want the pqact.conf action(s) on gemdata2 to
be identical to the ones on bigbird: ~ldm/etc/pqact.gempak_craft.tamu.
I would simply copy pqact.gempak_craft.tamu from bigbird to gemdata2
and make sure that you run the appropriate set of pqact actions in
~ldm/etc/ldmd.conf:

exec    "pqact -f CRAFT -p BZIP2/K[A-D] etc/pqact.gempak_craft.tamu"
exec    "pqact -f CRAFT -p BZIP2/K[E-K] etc/pqact.gempak_craft.tamu"
exec    "pqact -f CRAFT -p BZIP2/K[L-R] etc/pqact.gempak_craft.tamu"
exec    "pqact -f CRAFT -p BZIP2/K[S-Z] etc/pqact.gempak_craft.tamu"

OK.

If you are copying what is on bigbird, then the actions needed are
a FILE that writes the CRAFT pieces for each station to a hidden file
for that station/time followed by an EXEC action that renames the
hidden file to make it visible.

>I'm getting bad file format errors both when I run the script,

Which script?

>which makes pqact complain,

I don't understand.  Are you talking about pqact.conf actions?

I am assuming that you are saying that your pqact.conf action(s) on
gemdata2 are screwing up, and that results in the gempak routine failure
when reading a file on disk.  True?

If the answer is yes, then I recommend simply using the
pqact.gempak_craft.tamu file from bigbird and the CRAFT pqact exects
from bigbird's ldmd.conf file.  Since things work on bigbird, they
should work on another Linux machine doing essentially the same
ingest/file/processing.

>Thanks,

No worries.

Cheers,

Tom
