Before this article is considered for use the reader needs to be aware that the use of traditional EXP/IMP with 11.2 is desupported.  Ref Ch21 of Oracle Database Utilities 11g Release 2 (11.2), E10701-02

ORACLE Support cannot offer any guarantee of fix or workaround for such situations.

This article is for consideration if:

1. EXP 10.2 client (not DataPump export - EXPDP) is used against an 11.2 database
2. Following errors are seen on the TRIGGER phase:

. exporting triggers
EXP-56: ORACLE error 1455 encountered
ORA-1455: converting column overflows integer datatype
EXP-0: Export terminated unsuccessfully

3. Local 11.2 EXP utility does not cause problems
4. TRIGGER=N option allows 10.2 client EXP to complete
