ORA-09941:

Version of orapasswd or installer is older than file.
Cause: The version of orapasswd or installer that is being run is older than that of the ORACLE password file. Since the file version is only changed when the format is changed, this error means that the executable is using a different format than that with which the file was created.
Action: Run a version of the installer or orapasswd whose version is the same or later than that of the file.
