Transaction control and monitoring

From a management/administrative perspective:

Using the nzsql command (or any other SQL front end), privileged users can start, commit, and abort a transaction. User must have list object privileges on the database to which they are connected.
Using the nzsession command, privileged users can list and abort currently running SQL transactions.

If the system encounters a deadlock as it is processing transactions, it aborts one of the deadlocked transactions and displays Deadlock detected, resubmit your request.
