I killed a session and it is still running From a thread on Ask. Tom, when a session is killed The session is killed but it is being cleaned up. When you kill a session. When you do DML on a table, Oracle may make the changes to the base table almost immediately, even if you dont commit. The other sessions dont see these changes yet thanks to multiversion read consistency but the actual physical block may already be overwritten with your uncommited work. This is done because Oracle is optimized for commit. Most sessions should rarely rollback so Oracle anticipates by writing preemptively the changes. This is also one of the reasons that allows Oracle to have arbitrarily large transactions limited only by the size of the undo tablespace. The changes are not delayed much. This is what I use. I do this first query to find the sessions and the users select s.

One of the consequences is that rollback needs to undo the changes. The uncommited transaction is read back from the undo tablespace and each and every change is undone in reverse order. This can take longer than the initial DML for several reasons The rollback is not as well optimized, in particular multi row operations can take a lot longer than regular DML. Some changes are more expensive in reverse. For instance a delete which is a relatively cheap DML becomes an insert in reverse which is more expensive. This explains why rollback can take a lot of time. Asp Net 2010 Black Book Pdf. You have few means to accelerate the process.

If you shutdown the database normally or transactional or immediate, Oracle will wait for the process to complete so that the database is left in a consistent state. If you shutdown ABORT, the database will be left in an inconsistent state uncommited data written to disk and Oracle will resume the rollback as soon as the database is restarted.
