Will WinCC OA support Oracle 23 for RDB archiving?
Yes, of course.
Currently, the On-premise versions of the the newest Long-Term-Support (LTS) version Oracle 23ai have not yet been released.
According to Oracle this can be expected in the second half of 2024.

When it will be available, we will test the version thoroughly and then announce the support for RDB archiving with a later patch for the WinCC OA version 3.20 (12 weeks after the Oracle release latest).
Please note:
The innovation release Oracle 21c will not be supported by WinCC OA.
The support by Oracle for version 19c has been extended to April 2026.
