Posts about Deadlock written by Charles Hooper. December 6, 2009.

enq: TX - contention / Oracle / Sql.ru Jul 15, 2002 · Waits for TX in mode 4 can occur if the session is waiting for an ITL (interested transaction list) slot in a block. This happens when the session wants to lock a row in the block but one or more other sessions have rows locked in the same block, and there is no free ITL slot in the block. Usually, Oracle dynamically adds another ITL slot.
