RE: What happened!? IMPort tables with "User Defined or XML Datatypes"....so slow!

>>RE: What happened!?
 

What happened is that we appear to be hitting a nasty bug for AIX and 9203.
A memory leak related to IMPort and XMLTYPE w/ CLOB storage; Metalink Bug 3330477.
Casues IMP to slow to a crawl.  

I was wrong our env is 9203.

Try running a 10046 trace on the import session.

If the import is being done across the network you may find that imp is very chatty.
