add a custom projected coordinate system

How do I add a new projected coordinate system in 11g?  This is how I did it in 10g.

insert into cs_srs (cs_name, srid, auth_srid, auth_name, wktext) values 

  ('Mercator37', 49155000, 49155000, 'EDR', 

'PROJCS["Mercator",

   GEOGCS [

    "NAD 83 (Continental US)",

    DATUM [

     "NAD 83 (Continental US)",

     SPHEROID ["GRS 80", 6378137, 298.257222101]],

    PRIMEM [ "Greenwich", 0.000000 ],

    UNIT ["Decimal Degree", 0.01745329251994330]],

   PROJECTION ["Mercator"],

   PARAMETER ["Latitude_Of_Origin", 37.000000],

   PARAMETER ["False_Easting", 0.000000],

   PARAMETER ["False_Northing", 0.000000],

   UNIT["U.S. Foot",0.3048006096012192]]');
