Question

I used toad to connect to Oracle, issued a select query and while exiting it asked to issue commit or rollback. I pressed the escape key and the message box disappeared. Then I ended the connection. Will this cause any problems to the tables I queried? Will it cause the undo tablespace or rollback segment to go out of control? Thanks in advance.

Was it helpful?

Solution

This is what the Oracle PMON (Process Monitor) process will handle. If a session is terminated in a disorderly manner, then the session will be left in a state that must be cleared up. The PMON process will then roll back any active transactions.

So to answer your question: No, your transaction is no longer active and all your changes were rolled back (if you did not explicitly commit).
