You could try enabling the database for autodefer, as:


Log on as database creator, then
:dbutil
enable databaserootfilenamefor for autodefer
exit

This will effectively detach the database from the transaction manager.

You will run the risk (a very small one, I would 
think) of data base corruption in the event of a system failure.

You could mitigate the risk by ensuring you have 
a good backup of this database prior to the 
execution of this high transaction volume batch job.

To later reverse the transaction manager detachment if you wish, simply

:dbutil
disable databaserootfilename for autodefer
exit
