No. If you don't want a product, then you're always better off (in the sense of CPU load and bandwidth utilization) not receiving it. You would also be much better off writing the data-products to a local disk rather than an NSF-mounted one. This minimizes the risk of the pqact(1) process getting behind the addition of new products to the product-queue. Putting the pqact(1) process into verbose logging mode (via "kill -USR2") will indicate how far behind it is (2 more "kill -USR2" will return it to taciturn logging mode). > I have the space, and in the case of the > local drive, I discard the products I don't need anyway. I also vaguely > remember something about storing to an NFS mount versus a local drive... You might be thinking of our recommendation that data-products should not be written to NFS-mounted disks. > address@hidden .Leon]$ cat /usr/local/ldm/etc/pqact.conf|more > # Primary incoming data from NOAAPort Receive System > # Text Only > # Modernized PIL Regional Backup Data Storing Scheme > > WMO ^....[0-9][0-9] > (K|T|P|N)([^W]..|W[^O].|WO[^H]).*/p([^D]..|D[^P].|DP[^A])(.|..|...)$ > FILE -strip -overwrite /home/ldm/data/\2/\3\4 > > # Text Only > > WMO ^....[0-9][0-9] > (K|T|P|N)([^W]..|W[^O].|WO[^H]).*/p([^D]..|D[^P].|DP[^A])(.|..|...)$ > FILE -strip -overwrite /home/ldm/current/\2\3\4 > > WMO ^....[0-9][0-9] (K|T|P|N)(WOH).*/p(RRS)(FWR|TUA|ORN|ALR)$ > FILE -strip -overwrite /home/ldm/current/\2\3\4 > > > -- > Leon Minton, IT Analyst > Cooperative Institute for Mesoscale Meteorological Studies > Teamed with NWS-SRH-CWWD-DET (DOC/NOAA) Regards, Steve Emmerson > NOTE: All email exchanges with Unidata User Support are recorded in the > Unidata inquiry tracking system and then made publicly available > through the web.
