Oracle : Ошибка ORA-00260

"cannot find online log sequence %s for thread %s"
*Cause: The log sequence number supplied to the archival command does
not match any of the online logs for the thread. The log might
have been reused for another sequence number, it might have been
dropped, the sequence number might be greater than the current
log sequence number, or the thread might not have any logs.
*Action: Check the ARCHIVE statement, then specify a valid log sequence
number. Specify a valid log sequence number.
