APPLIES TO:

Oracle Database - Enterprise Edition - Version 11.2.0.4 to 18.3.0.0.0 [Release 11.2 to 18]
Information in this document applies to any platform.
This problem can occur on any platform.


SYMPTOMS

While exporting a schema with the datapump export utility the following errors occur :

 $ expdp schemas=<NAME1>.<NAME2> directory=dp_dir dumpfile=<DUMP_NAME>.dmp

Export: Release 11.2.0.4.0 - Production on Wed Aug 17 04:59:44 2016

ORA-39001: invalid argument value
ORA-39170: Schema expression '<NAME1>' does not correspond to any schemas.



CAUSE

The problem is caused by the fact that the dot (".")  in the schema name is parsed. The right escape sequence must be used in order to avoid this.



SOLUTION

The right escape sequence is  '\"' ( back slash + double quote).

The following datapump export statement  will work OK :

$ expdp schemas='\"<NAME1>.<NAME2>\"' directory=dp_dir dumpfile=<DUMP_NAME>.dmp
