Clean-up Service preferences
The Clean-up Service defines how the Connect database and the temporary files created
during Connect production runs are cleaned up after the production run has finished.
As part of the job production process PlanetPress Connect uses a database for intermediate
storage and also creates various temporary "managed" files. These files include data
extractions, configuration files and any intermediate files created during the production process.
Connect keeps track of all these files through references held within the Connect database.
All the files created and the database references to them are stored for a set amount of time in
order to allow Connect to reuse them. However, we do not want to store these indefinitely,
because the database would run out of space. The solution is to use the "Clean-up Service" to
remove the temporary data and files once they are no longer needed. This clean-up service is
usually managed by the Server Engine.
The more items that are present in the database, and the larger they are, the more time and
processing power (CPU) that will be required for cleaning them up. Thus a regular Clean-up of
the database (as often as possible)is recommended.
This is especially the case if items are not going to be retrieved from the database at a later
date. i.e. If the Connect job is not going to be re-run.
The clean-up can always be set to run outside of business hours (see the "Run according to the
cron schedule: Enter the interval at which the Clean-up service runs. To understand how to
write a cron job schedule, please refer to the Quartz Scheduler tutorial: http://www.quartz-
scheduler.org/documentation/quartz-2.3.0/tutorials/tutorial-lesson-06.html." on the facing page
option below), to reduce impact upon Production systems.
The values below define when the specified targets are to be set as being ready for deletion,
not when they are actually deleted. The actual deletion occurs only as per the cron job
scheduling; or when PlanetPress Connect is started (if Run at application start up is
selected); or when the Run Now button is pressed.
