If you want to comply with FIPS, you should see following documents:
Also pay attention to this (from http://docs.oracle.com/cd/E14072_01/network.112/e10746/asointro.htm#i1008266)
Oracle Advanced Security Release 8.1.6 has been validated under U.S. Federal Information Processing Standard 140-1 (FIPS) at the Level 2 security level. This provides independent confirmation that Oracle Advanced Security conforms to federal government standards. FIPS 140-1 related configuration settings are described in Appendix D, "Oracle Advanced Security FIPS 140-1 Settings".
The cryptographic libraries for SSL included in Oracle Database 10g have been validated under FIPS 140-2 at the Level 2 security level. FIPS 140-2 related configuration settings are described in Appendix E, "Oracle Advanced Security FIPS 140-2 Settings".
Right, I understand 10G is FIPS 140-2 compliant, but 11G and Advanced Security does not have any documentation supporting that.
Additionally, the 11G Administrators Manual specifically states 10G is FIPS 140-2 compliant, and continues to state how to configure 10G, and not mention 11g or Advanced Security.
