Standard component from CSS archives selected PV values into a mysql database. We use this twice (into the same database):

  1. Block archive, this just archives blocks and is restarted whenever the configuration (and blocks) change.
  2. Instrument archive, this is just started once and archives all PVs marked with the archive info setting which are in the database.

To see how to build this component see Building the archive engine for mysql
