Oracle : Ошибка ORA-16008

"indeterminate control file checkpoint"
*Cause: The control file for the database being opened for read-only access
was created using the CREATE CONTROLFILE statement. Therefore, a
control file checkpoint could not be calculated and the database
could not be opened for read-only access.
*Action: First, open the database for read/write access. This creates
a valid control file checkpoint. Then, reopen the database for
read-only access.
