VDBs in the DCT UI
Overview
DCT provides the ability to view, search, sort, and filter all VDBs for a connected Delphix infrastructure. You can access the VDBs list in DCT by navigating to Data > Data Management > VDBs, along with some useful column information like status, type, platform, engine, and tags. Click the View button on any line item to see the detail page of the selected VDB.
Users will only be able to see VDBs if they have been granted access via the Access Control system.
New features
-
2025.6 changes
The Overview tab of a VDB or dSource now shows the current Database state, whether the FileSystem is mounted, the current Timeflow state, and details of the NFS configuration, including:
-
NFS Protocol: Indicates NFS version that was last used to mount this source.
-
NFS Encryption: Flag indicates whether the data transfer is encrypted or not.
-
NFS Reason: Indicates reason why the source is being mounted with nfsVersion.
-
-
2025.4 changes
Support has been introduced for viewing and editing configurations for oracle VDBs and vPDBs within the VDB Detail Page, under the Overview tab. This enhancement allows users to manage configurations as needed.
VDB detail page
Overview
The default tab of any detail page in DCT is the Overview tab. This page shows which Platform the VDB is from and what the Status of it is, along with the following tiles.
-
Details: Shows useful information like the type of object it is (VDB in this case), the platform of origin, version number, dataset size, amount of unvirtualized space, if JDBC is used, associated database name, associated data connection name, associated file systems, timeflow status, NFS protocol status, NFS encryption status, NFS reason (if applicable), associated engine, and provides a direct link to the VDB in the engine.
-
Configuration: Shows whether automatic VDB restart is enabled, which VDB configuration template is selected (if applicable), if Change Data Capture (CDC) is on or off, and if a database user is set.
-
Notes: Shows any notes associated with the VDB
-
Environment Details: Shows the name of the environment where the VDB came from, environment type, operating system, timezone, associated user, and associated instance.
-
Tags: Shows any tags associated with the VDB.
Timeline History
This tab shows the VDBs bookmarks and snapshots. The bookmark details will include Name, Data Timestamp or Location, Log Delta, and Expiration. An operation to delete the bookmark is available with the action button on the right of a bookmark line item.
Data Timestamp is only shown when available for the bookmark. Data Location is only shown when the bookmark is created using a location.
Log Delta is the delta between a bookmark’s data timestamp and a snapshot’s timestamp when the bookmark’s data timestamp is available. It can also be the delta between a bookmark’s location and a snapshot’s location when the bookmark is created using a location.
Bookmarks
A list of all bookmarks generated on the selected VDB can be found under the "Bookmarks" tab. This page provides a list of all bookmarks allowing for general organization and actions (developers can use bookmarks as a refresh or provision point from the API).
Access
Users are able to audit which users have access to this particular VDB, what access group they belong to, and the associated permissions that each user has on that VDB. Admins are able to click on the "View" button to access further details under the access control screen related to that specific user.
VDB Config Templates
Importing and removing imported VDB templates from connected engines is an available action from the VDB Config Templates page.
To import a template, select the engines from the list in the import dialog.
To remove a template, select the engines from the list in the remove dialog.
VDB upgrade and migration
In DCT 2025.2.0, upgrade and migrate operations are only supported for Oracle and MSSQL databases.
As part of the goal to bring feature parity between virtualization engines and DCT, DCT now supports two additional dataset operations – Upgrade and Migration.
Upgrade
Upgrade Delphix Engines directly from Data Control Tower with guided options for Full, Apply Now, or Delay the Reboot upgrades. Choose the upgrade type best suited for the environment’s availability needs and downtime windows.
The Upgrade action is available from the action menu in a dSource or VDB detail page.
Container databases are not supported for upgrade.
Migrate
Migration enables users to move a VDB between compatible environments. Requirements for migration vary by database type—for example, Oracle VDBs must be disabled before migration is allowed.
The Migrate action is available from the action menu in a VDB detail page.
