Not sure what you mean. If I push the close button on the DA object, it says 
it's 'closed'. In that state, I wouldn't expect a transaction to re-open it, but 
if it did, I'd expect the DA's state to change to 'open'. That doesn't appear to 
happen ;-)

Also, I've had off-list reports of DCOracle2 keeping references to the session 
even once it's connection has been closed. The specific report is that the 
cursor carries on working even after you call db.close()
What kind of effect would that have here?

The same email also had reports of ZOracleDA leaking oracle connections, have 
you experienced anything like that?

Glad to see it's not only us non-paying customers who love NZO so much ;-)
Any joy fixing it?
