Hello,

when i read this doc
http://www.ibphoenix.com/resources/documents/general/doc_67

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 :
http://www.firebirdnews.org/?p=4475
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
stéphane
