See "UIM Software Compatibility" in UIM Compatibility Matrix for a full list of software requirements.

You must use the Software Development Kit (SDK) delivered with UIM 7.8.

This release includes the following features and enhancements:

• Introducing Service Impact Analysis
• Enhancements in UIM
• Enhancements in Unified Inventory and Topology and UIM Cloud Native Deployments
• Enhancements in ATA
• REST API Support for Service Impact Analysis
• Tech Stack Updates
• Updates to Hardware Sizing Guidelines

UIM 7.8 release introduces a new user interface, Service Impact Analysis, for analyzing service impact events.

Service Impact Analysis helps you to analyze the impacted resources for alarm events that are in TMF642 alarm events specification.

It collects the service impact data from an assurance system and displays the data in the form of reports. It also enables you to assign ownership to specific individuals and helps you to track and analyze the impact lifecycle using an analysis process.

You can perform the following tasks using Service Impact Analysis:

• View the summary of the Alarm Events passed from the assurance system.
• Viewing the analysis of service impacts data.
• Viewing the list of recent events.
• Generate reports.
• Sort the list of events and list of reports.
• Use global search for filtering and searching the events and reports.
• Customizing the impact reports and exporting them to XLS for further analysis.
• Viewing the insights for events and reports.
• View impacted resources in ATA.

See "About SIA" in Active Topology Automation and Service Impact Analysis User's Guide for more information.

This release includes the following enhancements in UIM:

• Saved search at group-level:

  • You can select a user group while saving search. This enables all users within the selected group to use the saved search. See "Saving a Search" in UIM Online Help for more information.

  • A new ruleset POPULATE_USER_GROUP and a new base cartridge ora_uim_savedsearch_grpupdate are added in this release. These help in updating user group information for the existing saved searches. See UIM Cartridge Guide for more information.

• UIM UI Search page enhancements:

  • Device Interface Search page: You can view the associated physical ports for Device Interfaces in the Device Interface Search Results table.

  • Physical Port Search page: You can view Connectivity Identifier for Physical Ports even when the connectivity is terminated on Flow Interface of the corresponding Device Interface. You can view the list of Connectivity Identifiers from the Physical Ports Search Results table. If there are multiple Connectivity Identifiers associated to a Physical Port, click on the required Connectivity Identifier to view the following details in Connectivity Identifier List table:
    • Device Interface
    • Flow Interface
    • Connectivity Identifier

  • Connectivity Search page: You can view A End Port Name and Z End Port Name for all connectivities that are terminated on Device Interface or Flow Interface in the Connectivity Search Results table.

The Authorization service now supports the following roles and user groups for Service Impact Analysis:

• SIA Administrator
• SIA Advanced User
• SIA User

See "About Authentication" in Unified Inventory and Topology Deployment Guide for more information.

Service Impact Analysis enables you to view alarm events associated with UIM resources. You can deploy Service Impact Analysis in Cloud Native environments.

Deploying Service Impact Analysis is dependent on ATA deployment. You must deploy ATA and create an ATA instance before deploying Service Impact Analysis.

See "Deploying Service Impact Analysis" in Unified Inventory and Topology Deployment Guide for more information.

ATA architecture now includes Service Impact Analysis. See "ATA Architecture" for more information.

Message Bus includes the following enhancements:

• Replaced the Zookeeper with KRaft.
• Provided one-time migration script to upgrade to KRaft mode.
• Each Kubernetes namespace allows only one Message Bus deployment.
• Support to capture log in external file.
• Authentication and ingress support for Mirror Maker configuration.

Active Topology Automation (ATA) 1.3.0.0.0 includes the following enhancements:

• Support to View Alarms at Subnode Level in ATA
• Support to Associate Alarms on Subnode
• Support for Extensibility while Processing an Alarm

In ATA, you can view alarms at a subnode level. You can click on the alarm to view the corresponding details.

See Active Topology Automation and Service Impact Analysis Guide for more information.

The alarms can be associated at the subnode level. See "Configuring Alarm Consumer" in Unified Inventory and Topology Deployment Guide for more information.

An alarm association can be extended based on configurations. You can provide custom implementation to associate an alarm with subnode type.

See "Configuring Alarm Consumer" in Unified Inventory and Topology Deployment Guide for more information.

UIM 7.8 includes REST API support for Service Impact Analysis. See REST API for Active Topology Automation and Service Impact Analysis for more information.

UIM 7.8 includes Tech Stack updates.

See "Unified Inventory and Topology Microservices" in UIM Compatibility Matrix for more information.

UIM 7.8 includes updates in the hardware sizing guidelines for UIM and its associated application components. For more information, see "Unified Inventory Management System Requirements" in UIM Installation Guide.

This section provides you with details on fixed and known issues.
