ORA-12660 Encryption or crypto-checksumming parameters incompatible


I am trying to run a BrioQuery report or use another database query tool to query an Oracle database, and am getting an error:

ORA-12660 Encryption or crypto-checksumming parameters incompatible


Note that the Oracle client is not available for Macintosh. Macintosh users can access BrioQuery via Citrix.


This error can sometimes be resolved with the following steps (for Windows):

  1. Close BrioQuery.
  2. Navigate, on your hard drive, to C:\Program Files\oracle\ora92\network\Admin
  3. Rename sqlnet.ora to sqlnet.oraOld
  4. Copy and paste the sqlnet.ora file attached to this article into that same location.
  5. Launch BrioQuery and try again to run the report.
