Check you oracle installation. If you do not know how yourself, then ask your Oracle DB administrator, if you have one. If this is your own Database, then ask on an Oracle forum how you can retrieve that info from the ORacle configuration (and, to be complete, how you can change it if need be).

hardly urgent. In fact there's no urgency at all.

You're effectively saying that you're more important than anyone or anything else, including the work that pays my rent and dinner.
That's extremely rude, and a blatant lie.
