The ORACLE_SID environment variable is set to +ASM. ASMLIB is not used in the configuration. You executed
the following command to startup the Automatic Storage Management (ASM) instance.SQL> STARTUP;
Which two activities are performed during a successful start up operation? (Choose two.)
A.
The databases configured to use the ASM instance are mounted
B.
The disk groups are mounted as per the ASM_DISKGROUPS initialization parameter
C.
ASM starts the Oracle Cluster Synchronization Services (CSS) daemon if it is not started
D.
ASM discovers and examines the contents of all files that are in the paths specified in the
ASM_DISKGROUPS initialization parameters
Explanation:
Refer to Starting Up an ASM Instance.
To start up an ASM instance, you must:
1. To connect to the ASM instance with SQL*Plus, you must set the ORACLE_SID environment variable to the
ASM SID.
2. The initialization parameter file, which can be a server parameter file, must contain: INSTANCE_TYPE =
ASM
3. The STARTUP command, tries to mount the disk groups specified by the initialization parameter
ASM_DISKGROUPS.
If ASM_DISKGROUPS is blank, the ASM instance starts and warns that no disk groups were mounted. You
can then mount disk groups with the ALTER DISKGROUP…MOUNT command.
The Cluster Synchronization Services (CSS) daemon is required to enable synchronization between ASM and
its client database instances. The CSS daemon is normally started (and configured to start upon reboot) when
you use Database Configuration Assistant (DBCA) to create your database. If you did not use DBCA to create
the database, you must ensure that the CSS daemon is running before you start the ASM instance.
