Release 23.4.1

Oracle Communications Cloud Native Core, cnDBTier 23.4.1 has been updated with the following new features or feature enhancements:

  • TLS Support for Georeplication: With this feature, cnDBTier automates the process of configuring TLS for georeplication between cnDBTier sites. On enabling this feature, the replication SQL pod uses the certificates provided or configured to establish an encrypted connection for georeplication. This ensures that the replication data transfer is secure. For more information about this feature, see Oracle Communications Cloud Native Core, cnDBTier User Guide and Oracle Communications Cloud Native Core, cnDBTier Installation, Upgrade, and Fault Recovery Guide.
    Consideration: If you are enabling TLS for the replication channels in this release, be informed about the following conditions:
    • You can't roll back from 23.4.x to previous releases.
    • You cannot upgrade to any future versions of 23.4.x. However, cnDBTier plans to resolve this upgrade restriction in a future release.
  • dbtrecover Support for Georeplication Recovery Between Different cnDBTier Versions: With this feature, the dbtrecover script supports georeplication recovery between sites that are running on different cnDBTier versions. For more information about this feature, see the "Recovering Georeplication Sites Using dbtrecover" section in Oracle Communications Cloud Native Core, cnDBTier Installation, Upgrade, and Fault Recovery Guide.
    Consideration: Consider the following conditions before using the dbtrecover script for performing a georeplication recovery between sites running on different cnDBTier versions:
    • The script supports georeplication recovery between sites only in the following cases:
      • The good site and the bad site (the site to be recovered) run the same cnDBTier version.
      • The good site runs a lower cnDBTier version. However, the cnDBTier release on both the good site and the bad site supports the same database replication REST API.
    • The script doesn't support georeplication recovery between sites in the following cases:
      • The good site runs a cnDBTier version that is higher than the version on the bad site.
      • The good site runs a lower cnDBTier version and uses a different database replication REST API from the one used by the bad site.
    • The following cnDBTier versions use the old database replication API:
      • cnDBTier versions below 22.4.2
      • cnDBTier version 23.1.0
    • The following cnDBTier versions use the new database replication API:
      • cnDBTier versions greater than or equal to 22.4.2 and less than 23.1.0
      • cnDBTier version greater than or equal to 23.1.1

Release 23.4.0

Oracle Communications Cloud Native Core, cnDBTier 23.4.0 has been updated with the following new features or feature enhancements:
  • REST APIs to Display cnDBTier Data on CNC Console: In this release, cnDBTier exposes the following REST APIs to CNC Console:
    • Backup list
    • Database statistic reports
    • Replication heartbeat status
    • On-demand backup

    CNC Console uses these REST APIs to fetch cnDBTier data and display them on the CNC Console GUI. This way, cnDBTier facilitates users to integrate cnDBTier on CNC Console and allows users to perform cnDBTier read operations such as checking the list of completed backups and overall heartbeat status. For more information about the feature and the REST APIs, see Oracle Communications Cloud Native Core, cnDBTier User Guide.

  • Network Policies: With this release, cnDBTier supports network policies to restrict incoming and outgoing network traffic. This ensures security and isolation of cnDBTier services in Kubernetes clusters. For more information about enabling and configuring this feature, see Oracle Communications Cloud Native Core, cnDBTier User Guide and Oracle Communications Cloud Native Core, cnDBTier Installation, Upgrade, and Fault Recovery Guide.
  • Support for New Versions of Software: cnDBTier has updated the following software in this release:
    • Oracle MySQL Cluster Database - 8.0.35
    • Spring Boot - 3.1.5
  • TLS Support for Georeplication: cnDBTier 23.4.0 doesn't support Transport Layer Security (TLS). Therefore, the feature is disabled in this release by default. Follow the updated procedures in the documents to avoid encountering errors while performing any operation. For the updated procedures, see Oracle Communications Cloud Native Core, cnDBTier User Guide and Oracle Communications Cloud Native Core, cnDBTier Installation, Upgrade, and Fault Recovery Guide.
