Note:

  • In case of shared cnDBTier between Console and NF, Console DB Profile sizing needs to be included in NF DB Profile sizing.
  • cnDBTier custom values.yaml file has been included along with Console package from 23.3.0 release. The yaml file reflects the above cnDBTier profile and is packaged along with the Console custom values.yaml file used for installation. For installing the DBTier, Please refer to the Oracle Communications Cloud Native Core, cnDBTier Installation, Upgrade, and Fault Recovery Guide.
