Scheduling Preferences
The scheduling preferences are a way to control precisely how the PReS Connect services work in the
background.
Whenever an operation is scheduled:
- The number of instances to use is determined based on whether the
operation is small, medium or large
- If there is a reserved instance for that type of command available
then it will use a reserved instance
- If no reserved instances are available then any unreserved instance
that is available will be used
- If no instances are available then the command will be blocked
until an appropriate instance becomes available
Scheduling Properties
- Definitions group: Defines
what is to be considered a Small or Large job. Anything in between is considered
a Medium job.
- Maximum records in a small
job: Enter the maximum number of records for a job to be
considered Small.
- Minimum records in a large
job: Enter the minimum number of records for a job to be
considered Large.
Changes made to these settings will be applied on the run. Existing jobs will be taken into account when determining if a job can run.
For instance, if the minimum records for a Large job is increased from 1,000 to 10,000 and a job of 2,000 records is already running, then this existing job will now be considered a Medium job.
Likewise, if the minimum records for a Large job is decreased from 10,000 to 5,000 and a job of 7,000 records is already running, then this existing job will now be considered a Large job.
Additional Scheduling Preferences:
Scheduling Preferences can be applied to the two distinct Engines used in the Connect production process. The Merge Engine merges the template and the data to create Email and Web output, or to create an intermediary file for Printed output. The intermediary file is in turn used by the Weaver Engine to prepare the Print output.
Each of these Engines has its own Scheduling Preference page:
