I've tried to Enable Geodatabase to existing user, but the ArcGIS show me: "Executing: EnableEnterpriseGeodatabase "Database Connections\RNCET - GIS2.sde" "C:\Program Files (x86)\ESRI\License10.2\sysgen\keycodes"
Start Time: Mon Jun 30 14:48:38 2014
WARNING 000152: Geodatabase instance already exists.
Succeeded at Mon Jun 30 14:48:38 2014 (Elapsed Time: 0.14 seconds)"

I have already two users SDE(SYSTEM TABLES) and GIS(FEATURES), but I want to use a MULTIGEODATABASE  with the same oracle instance.

ArcGIS 10.2 64 bits, Windows 7 64 bits, Oracle 11g R2.
