Table Of Contents
A clean-up of the database is performed at regular intervals in accordance with the settings
(see "Clean-up Service preferences" on page302).
The File Store
Connect has its own File Store which it uses for transient files.
The Clean-up service takes care of removing obsolete files when those files are not marked as
permanent (see "Clean-up Service preferences" on page302).
The engines
Datamapper engine. A Datamapper engine extracts data from a data file. This is an internal
engine, for which there are no settings to make.
Merge engine/s. A merge engine merges data with a template using the scripts in the template,
in order to create (Print orEmail) content items.
The number of merge engines is configurable (see Merge Engine Scheduling): it can be
increased depending on the capacity of the machine that runs the solution (see "Performance
Considerations" on page28).
Weaver engine. The Weaver engine creates Print output from Print content items. It takes the
settings made in Print presets or in the Print Wizard into account.
The number of Weaver engines is configurable as well (see Weaver Engine Scheduling).
Speed units
The number of 'speed units' is the maximum number of Merge engines or Weaver engines that
are allowed to work in parallel. The output speed of all engines together is limited to a certain
number of output items (web pages, emails, or printed pages) per minute. How many speed
units you have and what the maximum total output speed will be is determined by your licence
and any additional Performance Packs you might have.
PrintShopMail Connect always has just one speed unit. Performance Packs only increase the
output speed. But there is one important twist: when generating Print output, the limit imposed
by the number of speed units, only applies to the Weaver engine; when creating Email, the limit
applies to the Merge engines only (the Weaver engine is not involved). So, when generating
Print output, multiple Merge engines can be used. The number of Merge engines is only limited
to one when creating Email output.
