2025.5 version release (September 2025)

New features

License Report (Preview)

DCT introduces two powerful new administrative License Reports designed to give you complete visibility into your Delphix Platform's database source sizing. These reports will help you:
- Monitor current state: Get detailed insights into your virtualized and masked source environments through interactive graphs and tables
- Predict future growth: Analyze historical trends to make informed capacity planning decisions
- Comprehensive coverage: Support for nearly all Delphix products, database types, and versions
This feature-flagged capability is scheduled for release in early 2026. Want to help us validate this feature? Contact your Delphix Account Team to participate in our preview program.
Hook template management

Continuing our Headless Engine vision, we have added full Hook Template support to Data Control Tower. Users can easily import existing hook templates from their engines and re-use them directly within their dataset provision and management for all data platforms.
Oracle environment enhancements

We have introduced multiple improvements for managing Oracle environments, including the ability to add manual repositories, display more details in the Overview for attributes, listeners, and cluster configurations, and define the vCDB’s TDE password.
dSource configuration enhancements

You can now modify a dSource’s configuration, including its non-system username, password, and policies.
Oracle VDB provisioning enhancements

VDB provisioning now includes support for file mapping, custom environment variables, invoking data patch, VDB Config Templates, listener parameters, and auto-restart for RAC.
External PostgreSQL v15.x support

We have officially certified PostgreSQL v15.x external databases for use with Data Control Tower. This includes v15.13 certification and is available on Kubernetes and OpenShift deployments only. This enhancement expands deployment flexibility and ensures compatibility with the latest PostgreSQL features.
AppData V2P (Preview)

Starting in DCT v2025.5.0, AppData now supports V2P operations from snapshots, snapshot timestamps, or bookmarks of dSources and VDBs. This allows file copy or synchronization to user-provided locations for Unix-based plugins. This capability is currently available via API only.
ServiceNow Spoke

Transform your Self-Service experience with new out-of-the-box ServiceNow Catalog items:
- Refresh Operations: Refresh from Self, Parent, or Relative sources
- Bookmark Management: Create and delete bookmarks with ease
- Enable Catalog User: Streamline user onboarding without manual administrative overhead
The Enable Catalog User feature is particularly valuable for organizations looking to scale their ServiceNow adoption efficiently. New users can be onboarded automatically, reducing administrative burden and improving time-to-productivity.

See it in action! Check out the demo video to explore these new capabilities.
New and improved APIs and CLIs

The following endpoints and commands have been introduced or heavily modified. Documentation can be found within the Swagger API or the DCT Toolkit.
- Full SAP ASE API and CLI parity: Create and update ASE environments, repositories, and databases (source configs)
- AppData plugins: Upload, search, add, and delete AppData plugins with multi-engine support.

Fixed issues

Issue ID	Description
APIGW-12433	Fixed a memory leak issue in the data-library service.
APIGW-12451	Fixed an issue where mutually exclusive operations for VDBs were not correctly depicted. For example, enabled VDBs incorrectly allowed the Enable and Start operations, while disabled VDBs incorrectly allowed Disable, Start, and Stop operations. The UI now correctly disables conflicting actions based on the VDB state.
APIGW-12930	Users can now quickly find and select objects by name.
APIGW-12939	Fixed an issue where the VDB size shown in the Overview page did not match the actual size metrics in the CD engine. The Overview now correctly reflects the total size consumed by the VDB, consistent with the Storage report in the DCT Engine.
APIGW-13270	Fixed an issue during provisioning where updating the database name field would not update the VDB name field with the same value.
APIGW-13401	Added DateTimeStamp in the bookmark table for multiple VDBs.
APIGW-13473	Fixed an issue where repositories were not updating when the Staging Environment was changed while attaching an MSSQL Staging push dSource. Repositories now update correctly when the staging environment selection changes.
APIGW-13483	Fixed an issue with the Hook Template window being too small, causing the text area content to overflow when resized.
APIGW-13501	Fixed an issue during a Staging Push dSource creation with tags where the tags would not save with the dSource, resulting in the tags being lost during creation.
APIGW-13536	Fixes a failure when refreshing from relative for SDD replica child VDBs in the DCT GUI by correctly resolving the root parent when a VDB has no dSource parent, restoring the relative refresh selection and workflow.
APIGW-13602	Fixed an issue preventing the IMPORT_ENGINE_BOOKMARKS job from transitioning to the COMPLETED state.
APIGW-13612	Fixed an issue where the Infrastructure Connection wizard showed connector environments from other engines. Environments are now correctly filtered by their associated engine.
APIGW-13709	Fixed issues in the Policy Schedule cron expression validation. Invalid cron expressions now correctly block saving in the update window. In addition, deleting custom schedules now correctly updates the policy schedule.
APIGW-13790	Fixed an issue where the Staging CDB dropdown was not populated when linking an Oracle Staging Push PDB. The dropdown now correctly retrieves Staging CDBs from the updated dataset-staging-cdbs table using the new API.
APIGW-13812	Fixed an issue caused by stats on a Hyperscale execution exceeding 2 billion.
APIGW-14226	Fixed an issue with connecting the Delphix engine to the hypervisor's graphical console.

Known issues

Unavailable OCI Appliance installations: An error was discovered during the installation process when 8+ CPU cores were assigned to the appliance. If this limit does not affect you, contact your Account Team.
PostgreSQL external database versions 12.x and 13.x compatibility: The Dataset Performance graph is not compatible with PostgreSQL external database versions 12.x and 13.x. Upgrade DCT's external database to PostgreSQL 14.x or 15.x for full compatibility.

Issue ID	Description
APGIW-11450	Tags applied to engine-managed policies (refresh, restore, snapshot, etc.) may not persist after a restart of the DCT pods. Tags on DCT-managed policies and other objects are not affected.
APGIW-13711	When creating or updating policies through the API or DCT Toolkit, cron expressions are not validated. Submitting an invalid cron expression may cause policy apply jobs to remain in a STARTED state without user feedback. This issue does not affect users working through the UI, where cron validation is already enforced (APIGW-13709).
APGIW-13599	When a Compliance Engine data admin login fails due to invalid credentials, the engine may continue to appear as “Online” in the DCT interface. Users are not alerted to the failed login, which can result in stale utilization data and other inaccurate reporting.
APGIW-13509	When deleting engine-created VDB Snapshot policies from DCT, the policy is successfully removed but an error message is still shown. This issue does not occur when deleting DCT-created policies.
APGIW-13501	When creating a SQL Server staging push dSource, tags entered during the wizard appear in the summary screen but are not saved after the job completes.
