File permission problem and instance owner problem

Question

Hi all
Recently i have install oracle 11g R2 software ( Using oracle user).
oracle home owner is "oracle" and group "oinstall". ( oinstall is primary group and dba as secondary group for the owner "oracle")
At the same time I have create new user name "test" and group as "dba".
As a "test" user i can able to access the software , creating new oracle instance , stop and starting the oracle database (orcl).
But when I started the orcl database as test user.
I can see the different owner for that instance and file permission is also different ( In my cas oracle user is becoming owner for the orcl database , Which is created by the test user )
Please help me in this
