Purge Data

To reduce the database size of the ION database you can use the Purge Data page to purge OneView and Confirm BOD history data. You can purge data in two modes.

  • Manual Purge: You can purge the data as a one time manual activity. You have the option to simulate the purge before proceeding with actual purge.
  • Scheduled Purge: You can set a recurring schedule that triggers the purge process automatically in the background and runs without manual intervention.

Purge manually to optimize performance.

Schedule purges to avoid issues in Production environment such as OneView slowness.

Important! The purge process is now time-based and not id-based. All the documents are purged, including those in-flight, and not yet delivered.

Note: Purging a lot of data can have performance impact on database processing. To limit the impact of the purge action, consider to purge data in chunks. You can, for example, purge data per month or use the scheduler to regularly clean up the data.

You can purge this data:

  • OneView documents

    All OneView documents and related events and content where all of the related events happened before the purge date are deleted. Timelines before the selected data become unavailable. In this case messages are selected automatically. This option can only be purged together with the Document contents.

  • Document contents

    All messages that were registered in ION before the purge date are deleted. Related OneView timelines do no longer show the message content. If you only select messages, the OneView timelines remain available.

  • Statistics

    Some statistical events and process-related statistics that are used in some Homepages widgets and the Task Viewer contextual application are deleted.

    To optimize the purge process, select smaller chunks when purging, for example hours instead of days. Use the same value for all selected data.

  • Handled Confirm BODs

    All handled Confirm BODs with a time stamp older than the selected purge date are deleted.

Purge Criteria

You can choose the relative age of data to purge in terms of days or hours. All entities older than the specified time are deleted. You can specify separate relative ages for OneView documents, messages, and handled Confirm BODs.

Note: If the relative age specified in the purge criteria involves data from the ION 11.1 OneView, the purge run partially completes with only purging the ION 11.1 data. The subsequent purge run completely purges as per the selected criteria. See section Migrate ION 11.1 Oneview data for more details.
