ORA-19734: wrongcreation SCN - control file expects converted plugged-in datafile Cause: When a tablespace is plugged into a database, thetablespace is initially
read-only. Oracle converts the header of the plugged-in datafiles (assign thema
new creation SCN) when the tablespace is first made read-write. This erroroccurs
when the creation SCN in the file header is different from the creation SCN inthe
control file, possibly because this is the initial version of plugged-in datafile. Action: Eitherrestore the converted datafile or continue recovering the datafile.
