Oracle Error Message
ORA-01208: data file is an old version – not accessing current version
Reason for the Error
The checkpoint in the file header is less recent than in the control file. If opening a database that is already open by another instance, or if another instance just brought this file online, the file accessed by this instance is probably a different version. Otherwise, a backup of the file probably was restored while the file was in use.
Solution
Make the correct file available to the database. Then, either open the database, or execute ALTER SYSTEM CHECK DATAFILES.
