Disable foreign key in dbunit test - oracle

Question

I am using dbunit 2.5.4 with junit 4, Java 8, and an oracle db (11 something). I successfully downloaded my test db to a flat file (xml) following online tutorials. I now want to do a CLEAN_INSERT but I get a CyclicTablesDependencyException. The solution appears to be to turn off the foreign key checks but I am not sure how to do this. How can I disabled foreign key checks in my dbunit test when I am doing a clean_insert?

I don't know what all that (up to "Oracle") is (yes, I know, Google is my friend, but only if I use it).
However, if you want to move that "test DB" (is it really a database? Or is it a schema? I presume the latter, but - even if it is a former, no problem), I'd suggest you to use
Data pump Export (and Import), or
original EXP (and IMP) utilities
The first one is more powerful, but EXP & IMP are somewhat simpler to use (don't require access to DB server, you don't have to create a directory (an Oracle object), DMP file resides on your computer).
What is the export/import benefit? In your case Oracle will take care about constraints. Besides, you'd export all objects by default (tables, views, procedures, triggers, packages, sequences, ... - everything) in a simple manner. I'd suggest you to look at it.
Documentation is, as usual, on OTN (pick your 11 something version, although - for such a simple requirements - any version will do).
Here's a short demonstration: I'm exporting MIKE's objects (not that many of them) and importing them into SCOTT's schema.

Try disabling useSequenceFiltering: useSequenceFiltering = false
