Release 26.1.201 - G55031-01, July 2026

Feature Updates

• New Features:

  • Added the feature Starting cnDBTier Georeplication Between Sites using CNC Console GUI to let users select IP preference for the replication channel and gracefully stop/start georeplication from the CNCC Console GUI. Added supporting DB Tier APIs and GUI screens to avoid manual backend actions.

  • Added the feature cnDBTier Deterministic and Controllable Automatic Georeplication Recovery (GRR) to allow enabling/disabling Auto GRR and selecting a preferred backup site for recovery. Added new configuration parameters and REST APIs to GET/UPDATE/RESET Auto GRR behavior.

  • Added the feature DB Tier Event Details APIs to retrieve detailed DB Tier event records within a caller-specified time window using startTimestamp and endTimestamp. Added pagination via page size and page number to efficiently navigate large event volumes.

  • Added the feature cnDBTier Skip Exception Table Restoration to skip restoring data for Exception Tables during GRR while still restoring their schema. Added a new GRR state and backup-site API lookup so Exception Tables are detected and excluded from data restore by default.

  • Added the feature Support for Digital Signature of cnDBTier Cloud Service Archive (CSAR) to digitally sign 5G CNC CSAR software packages to meet ETSI NFV-SOL004 requirements. Added signature verification support to ensure package authenticity and integrity during delivery and deployment.
