Import nls_lang not compatible

Oracle Database Tips by Donald BurlesonNovember 3, 2015

Question:  I am running a data pump import and I get an nls_lang not compatible error.  I do not know the nls_lang of my dmp file.  How do I get the nls_lang to display for a dmp file?  Then, how do I overcome the nls_lang not compatible error?

Answer:  You can use the show=y parameter in the "imp" utility to see the nls_lang for a dmp file:

/u01> imp scott/tiger file=expdat.dmp show=y

import done in US7ASCII character set and AL16UTF16 NCHAR character set import server uses WE8ISO8859P1 character set (possible charset conversion)

To resolve the "not compatible error. make sure that the NLS parameters match on both databases

SQL> show parameter nls_lang

------------------------------------ ----------- --------------------------
nls_language                         string      AMERICAN

In this case you would to your nls_lang system parameter before the import:

$ export
