Flush data and reload configurations

This topic describes how to refresh server data, reload a configuration, and reset watermarks. These actions ensure an effective synchronization and help improve performance.

Flush server data

During iterations, data is collected and cached from the connectors. By flushing the server data, you clear out the cached data that was collected from the connectors.

Data is cached to improve performance. The following data is cached:

  • Property enumerations
  • Property lists
  • Type property lists
  • Type lists
  • Project lists

The Flush server cache action fetches the latest metadata from endpoint servers such as Jira and ALM/QC. We recommend that you flush the cache periodically to ensure that metadata changes are detected on the integrated/synced systems. If the system's metadata did not change, flushing is not required.

To clear and refresh the server data:

  1. Click the Actions button Actions button in the top banner.
  2. Select Flush Server Cache.
  3. Alternatively, stop and restart the Connect service.

Reload a configuration

This section describes how to reload a configuration. Reloading a configuration:

  • Stops all running connections.
  • Reloads the entire connect data structure into memory from the connect database.
  • Restarts any connection that was previously running.

To reload a configuration:

  1. Click the Actions button Actions button in the top banner. Select Reload Configuration.

Reset watermarks

Watermarks are added to indicate what was already synchronized. They act as a time and place marker so that the connector can compare what was updated, added, or deleted after the previous watermark was generated.

The watermarks are updated automatically. For example, after a synchronization iteration completes the watermark is moved forward in time.

In certain cases, you may want to manually reset a watermark. For example, if you have been synchronizing for an extended period of time and you currently need to change some of the configured mappings, you can reset the watermark. Resetting the watermarks ensures that all items are synchronized.

To reset watermarks:

  • For a specific connection: Click the cogwheel-shaped Modify Connection button adjacent to a connection name, and select Clear Watermarks from the menu.
  • For all active connections: Use the Batch utility scripts batch utility.
  • For a specific data source: In the main dashboard's Data Sources tab, select a data source and click the Save/Clear Water Marks toolbar button. This option is not available for all data sources.
