PART 2: Ways to move XML data; XMLTYPE w/ CLOB storage - RE: What happened!? IMPort tables with "User Defined or XML Datatypes"....so slow!

Env:
AIX 5.3
Oracle 9203
 
Considering that I am hitting a nasty bug for AIX and 9203 regarding
IMPort and XMLTYPE w/ CLOB storage and there is not obvious patch or
fix,
I need to find a way to move tables with XML data; XMLTYPE w/ CLOB
storage *AND* some tables with User Defined datatypes.
 
Would anyone be able to tell me if "SELECT INSERT..." over db links *OR*
SQLPlus COPY command supports XMLTYPE w/ CLOB storage?
 
PS Anyone have a query to pull a User Defined datatypes definition?
 
Please reply directly as well as to the list.
 
Thanks,

>>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.

        I don't have much experience with "User Defined Datatypes" nor
"XML
        Datatypes".=20
        Trying to move a database for a client that uses these
datatypes.
        (not sure but maybe some of them are Nested Tables or VARRAY's
vs. "User 
        Defined Datatype"...how can I tell the difference?)
        
        Anyway, in the same database I can IMPort
        * 15GB-20GB normal data (no indexes) per hour.
        * 10GB GB BLOB data per hour.
        but only
        * 324MB of "User Defined Datatypes" After 1 Hr. 15 Min. 
        * 53MB of "XML Datatype" After 30 Min.
