NAME

dbsubset2orb - monitor a database for new origins, and generate a /pf/orb2dbt packet and send it to an orb if a new origin meet certain criteria

DESCRIPTION

dbsubset2orb watches the origin table of a given database for new origin rows. An origin that meets specified criteria is packaged along with its event, assoc, arrival and netmag data into a /pf/orb2dbt packet which is written to the output orb.

Checks are made every 10 seconds, although this can be modified with the -s switch. A variable called last_lddate tracks the load time of the last origin that was processed, and this can be modified through the -l switch. Only origins with an lddate greater than last_lddate will be processed.

Other criteria are available for subsetting origins. By default, an origin must have a minimum of 4 associated arrivals. This can be overridden with the -n switch. The minimum magnitude by default is 0.0. This can be overridden with the -m switch. Typically a a magnitude is not computed by orbevproc for 30-60s after the origin is computed. By default, dbsubset2orb will wait up to 60 seconds for magnitude to appear. If it does not, the origin will be ignored. The time out parameter can be modified with the -t switch.
