Oracle Solution for Error imp-00020

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

What triggered the Error:

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

What should we do to fix it:

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