Khang, EXECing a program from the LDM configuration-file puts the process in the process-group of the LDM server; consequently, the SIGCONT signal sent by the product-queue library when a data-product is inserted into the product queue will be seen by all processes in the LDM process-group. This makes data-product delivery event-driven and results in low latencies. > EXEC "/home/ldm/bin/sendprod /dev/shm /dev/shm/prodflist 10 FT27 > >/var/opt/ldm/l > ogs/sendprod.out 2>/var/opt/ldm/logs/sendprod.err" > > what's the benefit of exec'ing a program in ldmd.conf ? > > line 21 in sendprod invokes piperead which removes data from the pipe-file > > ps -e|fgrep -q piperead || \ > (rm -f $pfil;piperead -p/var/opt/ldm/NEXRD3/output_pipe -o$pfil & > sleep $ptim) > > thanks Regards, Steve Emmerson Ticket Details =================== Ticket ID: ZRR-161467 Department: Support LDM Priority: Normal Status: Closed
