This document provides information about Oracle Communications Network Integrity Release 7.5.

This document consists of the following sections:

See Oracle Communications Service Catalog and Design Release Notes for the release notes for the Design Studio for Network Integrity feature.

See Network Integrity Licensing Information User Manual for license and dependency information for Network Integrity components and cartridges.

Software Compatibility

See Network Integrity Installation Guide for more information about software requirements and compatibility.

Support for the Optical TMF814 CORBA Cartridge to Discover and Reconcile DWDM Devices

The Optical TMF814 CORBA cartridge supports the physical discovery of entities in DWDM networks, detects and resolves discrepancies to the inventory (UIM) and also imports them into NI.

The Optical UIM Integration cartridge supports discrepancy detection on discovered SDH entities and reconcile discrepancies to the inventory (UIM).

You can use the Optical TMF814 CORBA and Optical UIM Integration cartridges to discover and model the discovered entities, to detect and resolve discrepancies. Once these devices are reconciled, you can use the DWDM Logical Discovery and Assimilation cartridges to create layer and service data for the devices in the inventory (UIM).

For more information, see Network Integrity CORBA Based DWDM Layers and Service Discovery and Assimilation Cartridge Guide, Network Integrity Optical TMF814 CORBA Cartridge Guide and Network Integrity Optical UIM Integration Cartridge Guide.

Support for the Optical TMF814 CORBA Cartridge to Discover and Reconcile SDH Devices

The Optical TMF814 CORBA cartridge supports the physical discovery of entities in SDH networks, detects and resolves discrepancies to the inventory (UIM) and also imports them into NI.

The Optical UIM Integration cartridge supports discrepancy detection on discovered SDH entities and reconcile discrepancies to the inventory (UIM).

You can use the SDH Discovery and UIM Integration cartridges to discover and model the discovered entities, and also detect and resolve discrepancies. Once these devices are reconciled, you can also create topology, trail or tunnel data for the devices in the inventory (UIM) using the cartridges.

For more information, see Network Integrity FTP SDH Logical Resource Discovery and Assimilation Cartridge Guide, Network Integrity Optical TMF814 CORBA Cartridge Guide and Network Integrity Optical UIM Integration Cartridge Guide

Support for Viewing the Save and Reset Button on the Review Discrepancies Page

On the Review Discrepancies page, you can view the Save and Reset button in the Search section when Advanced Search is enabled.

Enhancement in Localized Display on NI GUI

NI 7.5 supports the display names of specifications, attributes, and characteristics to appear in the language format of your choice.

See "Setting the Language Preference in the Browser" in Network Integrity Developer’s Guide for more information.

Support to Enable Auto Discrepancy Resolution for Various Discrepancies

NI 7.5 supports automatic discrepancy resolution to be classified based on different discrepancy types. This feature allows you to select discrepancies to be automatically resolved from the NI GUI when a scan is run.

See "Working with Automatic Discrepancy Resolution" in Network Integrity Developer’s Guide for more information.

Support to View Date and Time of Last Successful Login on NI GUI

You can now view the date and time of the last successful login at the top right corner of the UI. As a security measure, NI 7.5 stores the details of the successful and failed login attempts in the schema.

See Network Integrity Online Help and Network Integrity System Administrator's Guide for more information.

Support to Rediscover Failed Network Devices

NI 7.5 supports discovery scans to rediscover only failed network devices from the previous-run discovery scan instead of running a full scan to rediscover all network resources.

See Network Integrity Developer’s Guide and "Starting a Scan" in Network Integrity Online Help for more information.

Support to View Detailed Information of Failed Network Resources for CORBA and FTP Discovery Scans

You can now view the detailed information for network resources that were failed to be discovered when CORBA and FTP Discovery scans are run. This is possible by expanding the Addresses field within the Scan Result Page to view all the root-level resources that were failed during the discovery scan.

See Network Integrity Online Help for more information.

Support to Assimilate and Reconcile IP Links

NI 7.5 supports the retrieval and modeling of IP connectivities and assimilates them. It also detects and resolves discrepancies on the identified connectivities, and reconciles them into the inventory (UIM).

See Network Integrity IP Network Links Assimilation and Reconciliation Cartridge Guide for more information.

Support to Show Scan Progress of Individual Resources During Scan Run

You can now view the progress of discovery of individual resources when a discovery scan is being run.

See "Implementing Custom Code to Reflect Scan Progress for Individual Resources" in Network Integrity Developer’s Guide for more information.

Enhancement to Configure Review Discrepancies Page Size to View Large Number of Discrepancy Results

You can configure the page size to view the required number of discrepancy results on the Review Discrepancies page on the NI GUI. The discrepancies.page.size property defines the number of discrepancy results to be fetched from the database, and it can be configured to fetch the desired number of discrepancy results at a time.

See "Configuring Page Size for Viewing Discrepancy Results" in Network Integrity System Administrator’s Guide for more information about using the property.
