The procedure for shutting down Oracle RAC instances is identical to shutting down instances in noncluster Oracle databases, with the following exceptions:
In Oracle RAC, shutting down one instance does not interfere with the operation of other running instances.
To shut down an Oracle RAC database completely, shut down every instance that has the database open or mounted.
After a NORMAL or IMMEDIATE shutdown, instance recovery is not required. Recovery is required, however, after you issue the SHUTDOWN ABORT command or after an instance terminates abnormally. An instance that is still running performs instance recovery for the instance that shut down. If no other instances are running, the next instance to open the database performs instance recovery for any instances needing it.
Using the SHUTDOWN TRANSACTIONAL command with the LOCAL option is useful to shut down a particular Oracle RAC database instance. Transactions on other instances do not block this operation. If you omit the LOCAL option, then this operation waits until transactions on all other instances that started before you ran the SHUTDOWN command either commit or rollback, which is a valid approach, if you intend to shut down all instances of an Oracle RAC database.
Note:
SHUTDOWN TRANSACTIONAL and SHUTDOWN TRANSACTIONAL LOCAL both perform the same action on a nonclustered database but the two commands are different on an Oracle RAC database.

Use SRVCTL to shut down an Oracle RAC database or database instance. The respective SRVCTL commands (srvctl stop database or srvctl stop instance) provide shutdown options to perform an optimized transactional shutdown. Use the TRANSACTIONAL stop option with the srvctl stop database command and the TRANSACTIONAL LOCAL stop option with the srvctl stop instance command.
