In case of stand alone set up, if the 11.2 Database be managed by Oracle Restart ( srvctl stop/start ), then 'grid' user should also be a part of 'dba' group.

Here are my questions
1. In case of RAC, how srvctl in grid infrastructure home (owned by 'grid' user) can stop/start database? Is keeping 'grid' user in 'dba' group (The OSDBA group) not required in RAC installations containing more than one node?
2. To stop and start database, we can just keep 'grid' user in 'oper' group (The OSOPER group for Oracle Database). Why should that be in 'dba' group?
