Multiple sessions are inserting data concurrently into a table that has an LOB column. At some point in time, one of the sessions cannot find available space in the LOB segment and needs to allocate a new extent. Which wait event will be raised in the other sessions that need space in the LOB column?
Correct Answer: C
When sessions concurrently insert data into a table with an LOB column and one session needs to allocate a new extent because it cannot find available space, the wait event associated with this contention is "enq: HW - contention".
