Delayed Block Cleanout and Interested Transaction List
Continuing the Ric Van Dyke blog spotlight comes his article introducing me to DBC (Delayed Block Cleanout), ITL (Interested Transaction List), and how they work in conjunction with each other in DML operations! Not only does he introduce these concepts, but he proves out that the cleanout has changed in 12c and last week in his comments he confirms that Oracle development agrees that this is a bug! That is VERY cool!!
