DEPRECATION
ArcGIS Pro 2.9 and ArcGIS Enterprise 10.9.1 were the last ArcGIS releases to support Oracle 18c, since Oracle ended premier support for Oracle 18c on June 2021. Oracle also ends extended support for Oracle 12c on July 2022. Hence, the ArcGIS Q4 2022 release will continue to support only Oracle 19c (64bit) 19.3.0.0. Future releases of ArcGIS only support Oracle Database Long Term Releases.
For details on Oracle support for 19c (Long Term Release), see Upgrading to Oracle Database 19c. For details on Oracle Database releases, see the Release Schedule of Current Database Releases (Doc ID 742060.1).
