VDB refresh UI
Overview
The VDB refresh wizard in the Data Control Tower UI offers important engine refresh operations like:
Self-refresh by snapshot, timestamp, or location
Refreshes a VDB back to a point in its own history.
Refresh to parent by snapshot, timestamp, or location
Data is pulled from the VDB provision parent (the dSource or VDB from which the VDB was provisioned).
Refresh to relative by snapshot, timestamp, or location
Allows selection of data from either the origin dSource of the VDB (which could be the immediate parent, or parent of parent, etc.) or any VDB sharing the same origin dSource (which could be parent, child, sibling, or similar relationship).
Refresh to bookmark snapshot
Refreshes a VDB to a compatible bookmarked snapshot.
In order to refresh from a dSource or VDB, the account performing the action must have the REFRESH permission on both the VDB being refreshed and the dSource (or VDB) from which the data is being refreshed.
User interface
The self-refresh by snapshot operation can be initiated as an action from the VDB's own active timeline or timeline history view, using the action menu for snapshots.
All three refresh types can be performed by opening the refresh wizard on the VDB details page. In the first step, select the refresh source:
Next, select the snapshot or point in time to refresh to:
For self-refresh, a timeflow from the VDB’s own history must be selected, and then a snapshot within the selected timeflow.
For parent refresh, a timeflow from the VDB’s provision parent’s history must be selected, and then a snapshot within the selected timeflow.
For relative refresh, first a relative dSource or VDB must be selected, then a timeflow, then a snapshot.
For all three refresh types, review the summary page once configurations are complete, then click submit:
Refreshing happens asynchronously and takes a various amount of time. The DCT UI does not currently show asynchronous job progress or errors, please refer to the engine UI for this function.
Refresh to Bookmark
Bookmark is available as a Select Refresh Source option in the refresh wizard, which allows you to refresh from compatible bookmarks. Choose a bookmark from the list and click Next.
You can also refresh from a particular bookmark under the VDB details page, via the Bookmarks tab. Choose a bookmark from the list as the one to refresh from, then click the Actions menu and select Refresh to Bookmark.
