Question regarding the 2gig file size limit on HPUX 10.20

I understand the limit and the reasons the c call fails when writing to the filesystem, but have been informed by the sysadm's at the office that 10.20 does support >2gig files although it might take some tweaking to the kernal. One, can anyone validate this O/S support and speak about the required configuration? Two, would making dbexport think that it is writting to a streaming device (specifying a tapedev that is a file) get over this problem if the filesystem does indeed support > 2gig. Any input is appreciated. mac-
