VDB Group configuration management (add/remove VDBs and manage the order of execution)
DCT can add/remove VDBs to/from the group and arrange the order from which bulk operations (like refresh) will be applied. This is particularly crucial for data sources like Oracle EBS, where application files and the underlying Oracle database need to be refreshed in a specific order.VDB Group bookmark creation support
DCT can create a bookmark across one or more VDBs contained in the group, to provide a human–readable reference point for that specific point in time.VDB Group refresh support
DCT can refresh one or more VDBs contained in the group based on a specific bookmark reference or to the latest snapshot on each VDBs' respective parent (VDB or dSource).
