"data file is from before the last RESETLOGS"
*Cause: The reset log data in the file header does not match the
control file. If the database is closed or the file is offline,
the backup is old because it was taken before the last ALTER
DATABASE OPEN RESETLOGS command. If opening a database that is
open already 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.
*Action: Make the correct file available to the database. Then, either open
the database, or execute ALTER SYSTEM CHECK DATAFILES.
