Database Purge Scheduling
The purge operation removes older record versions, changes history and workflow trace data, and helps maintain a clean database.
You can invoke the purge operation as a workflow, a command-line tool, or as a scheduled job. TIBCO recommends scheduling the data purge to run regularly.
Beginning with TIBCO MDM 8.3.1release version, you can use interval-based purge to target records updated in a specified interval. Schedule history purges, for example, to run with an interval equal to 7 days to keep the history from growing too large. You can also use purge to remove data which is no longer needed. For example, test data which you can delete using the command-line purge.
If invoked as a workflow, the purge operation can only be run in two modes: deleting older record versions and deleting history. If invoked as a command-line tool, use the various options to trim unused test data, data sources, and repositories.
See Chapter 9, Configuring Purge in the TIBCO MDM System Administration for more details about the purge operation.
