Creating the OSDBA for ASM Group

You must designate a group as the OSDBA for ASM (asmdba) group during installation. Members of this group are granted access privileges to Oracle Automatic Storage Management.

Create an OSDBA for ASM group using the group name asmdba unless a group with that name already exists: 
# /usr/sbin/groupadd -g 54327 asmdba
