dbms embedded

hi,
there is a version of Embedded database (serverless) certified with NetExpress\Visual cobol?
I desire the database system is "hidden" from the application’s end-user, and easy to install without server\client connection and setup.
the Cobol application currently works with UDB\DB2 and uses embedded sql statement in exec EXEC-SQL ... END-EXEC
I release this product on win\unix using "Cobol Runtime Server 2013" or "Server for Cobol 5.1"
thanks
