Oracle : Ошибка ORA-10626

"specify timeout for online index rebuild to wait for DML"
*Action: set this event only under the supervision of Oracle development
*Comment: Change the behaviour of an online index rebuild such that it
will timeout, rather than wait indefinitely for existing DML
to complete.
The event level is the number of seconds the online index rebuild
should wait. Values outside the legal range of 2 to 300 seconds
will be adjusted automatically.
