You have three production databases, HRDB, FINDB, and ORGDB, that use the same ASM instance. At the
end of the day, while all three production database instances are running, you execute the following command
on the ASM instance:
SQL> shutdown immediate;
What is the result of executing this command?
The ASM instance is shut down, but the other instances are still running.
It results in an error because other database instances are connected to it.
All the instances, including the ASM instance, are shut down in the IMMEDIATE mode.
HRDB, FINDB, and ORGDB instances are shut down in the ABORT mode and the ASM instance is shut
down in the IMMEDIATE mode.
