ORA-00054: resource busy and acquire with NOWAIT specified or timeout expired
...your session has aquired the lock. So you are good.
DDL auto-commits. This frees the locks.
DML statements will 'wait' or as developers call it 'hang' while the table is locked.
I use this in code that runs from a job to drop partitions. It works fine. It is in a database that is constantly inse...

...latter will be roughly twice as fast, because the 2nd ExtractMin is nearly free. Our algorithm extracts a batch of Min elements of which many are discarded; a waste on a Bin Heap, but better on a Fib Heap. Sadly this isn't clearly reflected in the time complexity people provide when talking about H...

That said, compile times have already improved noticeably going...
