Hi,

	I've experienced this problem on
	Solaris 2.7, and Oracle 8.1.6.2.
	On the export script,I changed 
	the "direct=y" to "direct=n",
	to use the conventional path.
	Then, the import worked fine.
	The export in this case was a 
	"full" one.
	I went through the same ritual
	that you did, increasing the buffer
	size, but that did not work.
	I contacted Oracle support, and they
	had me try numerous combinations of
	export/import. When doing 
	a "direct" export on a single table,
	and then doing the import that seemed
	to work. 
	The bottom line for me, is that I must
	use a conventional export for now,to
	guarantee that the import will work.
	The performance suffers but it works.
	But my original problem still remains
	unresolved.

Hi Gang,
I'm receiving the following error on a Solaris 2.8 with Oracle 8.1.6 and 2gig memory:

IMP-00020: long column too large for column buffer size (40)

The error action in the documentation says this:

Cause: The column buffer is too small. This usually occurs when importing LONG data.

Action: Increase the insert buffer size 10,000 bytes at a time up to 66,000 or greater (for example). Use this step-by-step approach because a buffer size that is too large may cause a similar problem.

Following the recommendation didn't help. It doesn't seem to matter what value I put in I always get the same message. I was able to import the same table on an NT database with smaller init.ora settings. Any ideas?

TIA,
-Rocky
