Subject Sweep interval : OST - OIT OR OST - OAT ?
Author Vander Clock Stephane

when i read this doc

The automatic sweep is kicked off when the difference between the OAT
and the OST is greater then the sweep interval

but when i read this :
The automated sweep will start if the difference between OST (Oldest
Snapshot Transaction) and OIT is greater than the sweep interval defined

What is good answer ?

also what is OIT? isc_info_oldest_transaction or isc_info_oldest_active ?

thanks by advance
