Starting the Ingestor

When the computer is powered up, the ingestor starts automatically. If you are unsure about the state of the ingestor, shutting down and restarting is the recommended procedure.

The startup script, /etc/rc3.d/S99inge (which should be hard linked to /etc/init.d/ingcntl), starts the ingestor automatically when the system is rebooted. Two lines in the script are of particular interest: the line that sets the environment variable WRAP, and the line that sets the directory to write the data and spool files to.

WRAP is the maximum number of megabytes of unread data (spool files) the ingestor can store before overwriting occurs. At delivery, it is set to 50 (50 megabytes), which represents about 4.15 minutes of data. If the client decoder falls behind the ingestor by more than 4.15 minutes, the oldest data in the FIFOs is overwritten.

The line cd /<directory> indicates the directory to write the data and spool files to. The table below shows the defaults for SDI versions 2000jan12 and later.

Data Type Directory
GOES Channel GINI files /data
NCEP/NWSTG spool files /data
Dual card - card 1 (NCEP/NWSTG spool files) /data
Dual card - card 2 (GOES Channel GINI files) ~mcadde/mcidas/data
