Details of the latest Siebel CRM 26.3 Release Update under the Continuous Delivery Model. This Update was GA on 24th March, 2026.
This comprehensive Update contains many new features and delivers lots of key bug fixes.
Developer Experience
In this release you can find three key features related to improving Developer Experience.
Enterprise Cache Operational Enhancements
This enhancement provides the following operational benefits:
- When deploying the Enterprise Cache Client Profile for your deployed Siebel servers, you can deploy the Client Profile once and it will automatically deploy to all your Siebel Servers. This will make your deployment of the Client Profiles much faster and less error prone.
- When deploying the Enterprise Cache Client Profile, SSH tunnels are established automatically from each Siebel Server deployed to each Coherence Server that is deployed.
- Improvements to the notification of Coherence cache status if the Coherence cache becomes unavailable and when it regains its footing.
There are two areas where you can see the status of the Coherence cache accurately:
- Help > Technical Support menu in the Siebel CRM Application.
- Siebel Management Console (SMC) Cache Status tab.
REST APIs for Workspaces
REST APIs allow Workspaces to be called independently without the need for the Web Tools or Siebel Tools user interface allowing automation and diverse use-cases. The REST APIs will extend Developer automation capabilities and save time.
- Create Workspace
- Checkpoint Workspace
- Revert Version
- Delete Workspace
- Submit for Delivery
- UndoSubmit for Delivery
- Deliver Workspace
- Rebase Workspace
- Cancel Rebase
- Finish Rebase
Web Tools Applet Method Menu Wizard
The Siebel Tools Applet Method Menu Wizard allows you to modify an Applet Method Menu. This wizard has been re-implemented in Web Tools allowing you to quickly modify Applet Menus.
Easier Updates – Schema Changes without Downtime for Updates and Migration
This feature leverages capabilities available in the Oracle and Microsoft SQL Server database engines that allow for online modifications to schema objects.
Benefits
Downtime is avoided during schema changes, ensuring that all employees, partners, customers, and integration points have access to user data in the Siebel CRM database, even when the schema structure is being modified.
Examples include:
- During the application of a Siebel Monthly Update’s “PostInstallDBSetup” or “RepositoryUpdate” processes, which can make changes to the physical schema.
- Performing a migration from a Development environment to any downstream environment, including Production.
NOTE: Full Runtime Repository Migration will leverage this feature to avoid changes required to modify schema objects, but there will still be downtime required to rename the Repositories.
Additional Background
Changes to database schema objects is performed using “Data Definition Language” (DDL). When DDL is provided upon an existing object (such as a change to a column definition) or to create certain kinds of new objects (such as indexes), the traditional approach that the various Siebel CRM utilities have used could introduce “table locks” or other conditions that would block end users from being able to use the application while the DDL was executing.
When this occurred, downtime could occur during the application of Siebel Updates (PostInstallDBSetup or RepositoryUpgrade) and Migration operations.
Basic Technical Information
By modifying our existing utilities to leverage built-in capabilities of modern versions of the Oracle and Microsoft SQL Server database platforms, we are able to execute DDL that accomplishes the same end result without forcing downtime.
- For Oracle platforms, we leverage the DBMS_REDEFINITION package to make changes to objects without making any schema objects offline.
- For Microsoft SQL Server platforms, we leverage the “ONLINE” keyword to modify objects without bringing any schema objects offline.
For more information on the technical details of these database-level capabilities, please refer to the Oracle or Microsoft documentation as appropriate.
NOTE: This change is not applicable to either DB2 database platform.
Siebel UCM: Publish In Hybrid Mode
Siebel Universal Customer Master (UCM) is enhanced to enable publishing to multiple middleware systems or combinations of middleware and edge systems in hybrid mode. Hybrid mode enables UCM to publish messages to all configured middleware and edge systems, regardless of their integration protocol (SOAP or REST).
With this capability, customers can design flexible and complex integration architectures — for example:
- Integrating both SOAP and REST-based systems through separate middleware platforms.
- Seamlessly connecting legacy and modern applications to UCM without protocol limitations.
This feature removes the current single-middleware restriction and allows enterprises to achieve unified, multi-protocol integration across diverse system landscapes.
Replacement of Obsolete Data Types from Oracle and MSSQL Databases
This feature provides a utility to convert obsolete Column types, such as Oracle’s LONG and Microsoft SQL Server’s TEXT/NTEXT to their modern equivalents: CLOBs and VARCHAR(max)/NVARCHAR(max).
The driver behind this is that the respective database vendors deprecated these data types a number of years ago and modern database engines are no longer being optimized for these older types. Replacing them with their modern equivalents will take advantage of their inherent benefits, such as greater data storage space, as well a future-proofing should either vendor ever elect to end support for these.
Customer Order Management – Improved Promotions UX
In Siebel Customer Order Management, a Bundle Promotion definition can have hundreds of products from various relationships to choose from. To make it easy for sales agents to capture a customer’s quote or order, the “Edit Promotion” User Interface has been enhanced to support pagination and search. As a result, an agent can quickly add one or more products using a new pop-up applet, improving productivity and ensuring data accuracy.
