EXP-00008: ORACLE error 1455 encountered Tips

Oracle Database Tips by Donald BurlesonDecember 13, 2015

Question:  I an getting this EXP-00008 ORA-1455 error when attempting to export a table:

EXP-00008: ORACLE error 1455 encountered
ORA-01455: converting column overflows integer datatype

EXP-00008: ORACLE error 1455 encountered
ORA-01455: a convers?o da coluna causa overflow do tipo de dados do inteiro
EXP-00000: Export terminated unsuccessfully

How to I complete my export without the EXP-0008 Oracle error 1455?

Answer:  This is likely a bug. See Bug # bug #4270321.

Also, see MOSC note 351233.1, issue in fixed in 10.2.0.

Try adding this to get around the bug:

constraints=n indexes=n statistics=none

The older exp utility has been deprecated in favor of the Data Pump utility (expdp) and you can get complete directions in the book Advanced Oracle Utilities.

Why not use Data Pump instead of the older exp? It is called Data Pump expdp.  If you are exporting for importing into another version, Oracle has a VERSION argument.

See here on the ORA-01455
