In Oracle January 2025 RU patches, a new and good change has been introduced. The default parameter DB_LOST_WRITE_PROTECT value changed from none to “AUTO” after applying the RU. This is a good move to ensure data protection and detecting problems early. I have talked about database lost write issue in an old blog post: https://geodatamaster.com/2020/09/04/oracle-database-lost-write-detection-recovery-options/
