I am exporting models from one user and importing them back into a different user. When I hardcode my schema_remap argument the import works without error. When I build the schema_remap parameter dynamically, I get the following error.

import_model failed! Error=ORA-40223: data mining model import failed, job name=
CLUSTADMIN_imp_37, error=ORA-31627: API call succeeded but more information is a
vailable
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at

The schema_remap argument that I am building looks just like the hardcoded one as I am printing it out before the call.
'CLUSTADMIN:JDOE'

Any ideas as to what the error means?

Also, if I import a model into a user schema, should that user be able to see the model when they SELECT from DM_USER_MODELS? This structure is empty but I do see model tables in the user's schema after the export.

Thanks,
