Extent allocation

[svk]

I am interested in knowing when a table grows.

Is there a way to get notified when an extent gets allocated to a table ?
Is there any dd view that has this info ?
Is there any tool that does this ?
Is there any event that can be set to get this info ?

Any input will be greatly appreciated....

I dunno for what reason you need this information but,You can get the number of extents from DBA_SEGMENTS view.

Write a Sql scripts which tracks the number of extents in this view and send you a note whenever extents increments.
