Release 25.2.200 - G49042-01, December 2025

Major Architecture Restructuring: Data Director Group Classification

This release introduces a fundamental transformation in the OCNADD architecture. The previously singular Worker Group has been decoupled and re-architected into two specialized functional groups: the Relay Agent Group and the Mediation Group.

This architectural shift impacts the entire system workflow and is reflected throughout this document:

• Group-Specific installation, configuration and uninstallation procedures:
  • Configuration procedures are no longer generic to a "Worker Group." All setup procedures are now distinct for Relay Agent nodes and Mediation nodes or namespaces.
• Customization:
  • Several unsupported parameters have been removed.
  • Parameters have been classified for each group.
• Upgrades and Rollback:
  • Upgrade is replaced with a migration procedure.
  • In-service rollback is not supported in this release.
• Fault Recovery:
  • Several procedures have been updated for the new architecture.
