ORA-28343
failure to encrypt data or redo
Cause
Data or encryption metadata might have been improperly altered or the security module might not have been properly set up:
- For redo, a key change might have been in progress or might have been in an invalid key state.
- For redo transport, other attempts will be attempted.
See the trace files for additional information.
Action
For redo, if the problem persists, remove the ENCRYPTION attribute from the LOG_ARCHIVE_DEST_n initialization parameter.
