Hi Gilbert and Daryl
Thanks for your fast answer. Yes, I am using LDM 6.8.1. I changed the file
ldmadmin-pl.conf to $pq_size = "4G", because I am ingesting data from
CONDUIT (GFS model). The ldm.pq file has around 4 G (4 075 618 304), that is
why I want to delete it.
"This 'file' can be thought of as a rotating queue of data slots where
products are inserted, deleted, etc as the running LDM processes see fit."
Then, I can't modify it, the products will go out of the file just by LDM,
and it will be always around 4 G? One more question: so, the size of this
file will not disturb the ingestion of data by LDM?
I am asking this because I had problems to receive data from CONDUIT (GFS
12hs) and I thought that maybe the problem was the size of the file ldm.pq.
Using ldmadmin watch, I saw that the model was acessed correctly, but the
folder at my machine (order in pqact) was empty.
The lines of pqact:
CONDUIT ^/data/nccf/com/gfs/prod/gfs\.(.*)/gfs\.t..z\.pgrb2f(.*)
!grib2/ncep/GFS/#000/(.*)!
FILE /usr/local/ldm/data/modelos/NCEP/GFS/50km/GFS50_\1.grib2
Thanks a lot
