Developer Experience: Enterprise Cache Operational Enhancements

The Enterprise Cache Operational Enhancements enhancement provides these 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's deployed.
  • Improvements to the notification of Coherence cache status if the Coherence cache becomes unavailable and when it regains its footing.

Here's where you can accurately see the status of the Coherence cache:

  • Help > Technical Support menu in the Siebel CRM Application
  • Siebel Management Console (SMC) Cache Status tab
Note: You don't need to do a Repository update for this feature.

Learning Resources:

This feature is documented in the Siebel System Administration Guide: Siebel CRM and Coherence Enterprise Caching.

Training about this feature is available on Oracle University.

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” UI has been enhanced to support pagination and search. As a result, an agent can quickly add one or more products using a new popup applet, improving productivity and ensuring data accuracy.

Note: You do need to do a Repository update for this feature.

Learning Resources:

This feature is documented in the Siebel Order Management Guide: Editing Bundle Product Promotions.

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 lets UCM 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 lets enterprises achieve a unified, multi-protocol integration across diverse system landscapes.

Note: You do need to do a Repository update for this feature.

Learning Resources:

This feature is documented in the Siebel Oracle Customer Hub (UCM) Master Data Management Reference: Configuring Publish and Subscribe Functionality.

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.

With this feature, you avoid downtime 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 of when this feature comes into play include:

  • During the application of a Siebel Monthly Update's "PostInstallDBSetup" or "RepositoryUpdate" processes, which can make changes to the physical schema
  • When performing a migration from a Development environment to any downstream environment, including Production
Note: Full Runtime Repository Migration leverages this feature to avoid changes required to modify schema objects. However, there will still be downtime required to rename the Repositories.

Additional Background:

Changes to database schema objects are performed using Data Definition Language (DDL). When DDL is provided for existing objects (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 can execute DDL that accomplishes the same end result without forcing downtime:

  • For Oracle platforms, we leverage the DBMS_REDEFINITION package to change 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.

Important: This change is not applicable to either DB2 database platform.
Note: You don't need to do a Repository update for this feature.

Learning Resources:

This feature is documented in the Siebel Database Upgrade Guide: Siebel Database Utilities.

Training about this feature is available on Oracle University.

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 many 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 as future-proofing should either vendor ever elect to completely end support for these.

Important: Please review the training material for important considerations before running this utility.
Note: You don't need to do a Repository update for this feature.

Learning Resources:

This feature is documented in the Siebel Database Upgrade Guide: Converting Obsolete Column Types on Oracle and Microsoft SQL Server Database Platforms.

Developer Experience: Web Tools Applet Method Menu Wizard

The Siebel Tools Applet Method Menu Wizard lets you modify an Applet Method menu. This wizard has been re-implemented in Web Tools so that you can quickly change Applet menus.

Note: You don't need to do a Repository update for this feature.

Learning Resources:

This feature is documented in the Configuring Siebel Business Applications Guide: Using the Applet Method Menu Item Wizard in Web Tools.

Training about this feature is available on Oracle University.

Developer Experience: REST APIs for Workspaces

REST APIs allow Workspaces to be called independently, without the need for the Web Tools or Siebel Tools UI – thus allowing automation and diverse use-cases. The REST APIs extend Developer automation capabilities and save time.

Here are some actions available with this feature:

  • Cancel Rebase
  • Create Workspace
  • Checkpoint Workspace
  • Revert Version
  • Delete Workspace
  • Submit for Delivery
  • Undo Submit for Delivery
  • Deliver Workspace
  • Rebase Workspace
  • Finish Rebase
Note: You don't need to do a Repository update for this feature.

Learning Resources:

This feature is documented in the Siebel REST API Guide: Invoking Siebel REST APIs for Workspaces.

Siebel Cloud Manager - Smarter Ingress Routing

Siebel Cloud Manager introduces support for Traefik as part of a Kubernetes deployment, to ensure continued security, support, and modern ingress traffic management. Support for Traefik is necessary because NGINX Ingress reached end-of-life in March 2026.

Traefik provides automatic SSL management, dynamic service discovery, and faster routing updates, reducing operational complexity. Its cloud-native design improves observability, scalability, and maintainability, and provides for the easy adoption of the Kubernetes Gateway API (a flexible, multi-protocol way to manage traffic routing).

This enhancement ensures Siebel CRM deployments on Kubernetes remain secure, reliable, and aligned with CNCF guiding principles.

Learning Resources:

This feature is documented in the Siebel Deploying Siebel CRM Containers on Kubernetes using Siebel Cloud Manager Guide: Managing Ingress using Traefik.
