mahsnj , PMFJI, but the "Oracle9i Database Utilities" manual, in chapter 1 - Export, says :
"Rows in tables that contain objects and LOBs will now be exported using conventional path, even if direct path was specified."
SO, I pass a BUFFER param always, so IF my direct-path ends being "downgraded" to an conventional path due the LOBs it uses the correct BUFFER, and if not BUFFER is ignored (at least this have been my experience).
why do you need to make an export? Have you tried to copy the data via db link?
ummm you should be providing an update with what you have done
Finally Option-2 works fine for me.
Exp system@INTORA1 TABLES= (COL.ABC_TEXT) FILE=C:\ABC_TEXT.dmp BUFFER=37748736
Thanks all for there help.
