Interval in Record Versions

If a repository contains a large number of records, all of them do not change at one time. When you run the purge on a regular basis, you may want to purge only the changed records.

To evaluate only the changed records, you can specify an interval. If the frequency of running the purge is 7 days and you are regularly running the purge, you can set the interval to 7 days. In this case, purge considers only the records that are changed in the last 7 days. Specifying the interval speeds up the purge process.

The interval defines the window from the cut off date of the purge. For example, specifying interval of 10 for the cut off date of Jan 20, 2013 indicates that only records modified in 10 days from the cut off date and prior to it are considered (Jan 20 inclusive, and up to Jan 10 exclusive). If you do not specify an interval, all records are considered. If the value is less than one, it is considered as null.

You can specify an interval in the following ways:

  • Add Interval as an input parameter in a workflow. For more information, refer to the Purge activity in TIBCO MDM Workflow Reference.
  • Specify <Interval> tag in the purge scheduled job policy. For information, refer to Job Scheduler.
  • Specify an -i option in the command line parameter. For information, refer to Purge Using Command Line.
  • Specify Interval parameter in the FileWatcher.xml. For information, refer to Workflow or FileWatcher Methods.
