When you install earlier Oracle Database releases on Oracle Grid Infrastructure, use Oracle ASM Configuration Assistant (Oracle ASMCA) to create and modify disk groups.
Releases prior to Oracle Database 11g Release 2 used Oracle Database Configuration Assistant (Oracle DBCA) to perform administrative tasks on Oracle ASM. Starting with Oracle Database 11g Release 2 (11.2), Oracle ASM is installed as part of an Oracle Grid Infrastructure installation. You can no longer use Oracle DBCA to perform administrative tasks on Oracle ASM.
