To prevent performance degradation, you can remove outdated matching metadata. Business users can perform this action manually using the Purge old result service. See Purging old results for more information. As an administrator you can automate this service using the EBX® scheduler.
When you use the scheduler, you'll create:
a task for each table whose matching metadata you want to purge.
a schedule, or time increment that defines how often the task runs.
a scheduled task that links the task to the schedule and enables or disables execution.
To schedule regular purges of matching metadata:
Navigate to Administration > Technical configuration > Task scheduler > Tasks and create a new task.
Provide a name, optional description, and in the Specification group:
For Module select Match and Merge.
For Class name, enter: com.orchestranetworks.addon.mame.scheduler.SchedulerPurge.
Save, but do not close the task.
After successful save, the Specification group displays the Dataspace, Dataset, and Table fields.
Use the fields displayed to specify the location of the table where you want the Purge old results service to run. Note that you must enter the full table path, for example: /root/<your_table_name>.
Save and close the task.
Go to Schedules and create a new schedule.
Add a name and use the Cron expression field to write a cron expression that defines the schedule increment. Run the purge weekly or every two weeks for most workloads. See the TIBCO EBX® documentation for more information about Cron expressions and their syntax.
Save and close the schedule.
Go to Scheduled tasks and create a new record:
Select the Task created in earlier steps.
Select the Schedule increment created in the previous step.
Specify whether the scheduled task is active.
Save and optionally close the record.
When the task is active, the UI displays the next planned execution time.
