Demo Questions
Question 1
A database instance is using an Automatic Storage Management (ASM) instance, which has a disk group, DGROUP1, created as follows:
SQL> CREATE DISKGROUP dgroup1 NORMAL REDUNDANCY
FAILGROUP controller1 DISK '/devices/diska1', '/devices/diska2'
FAILGROUP controller2 DISK '/devices/diskb1', '/devices/diskb2';
What happens when the whole CONTROLLER1 Failure group is damaged?
- The transactions that use the disk group will halt.
- The mirroring of allocation units occurs within the CONTROLLER2 failure group.
- The data in the CONTROLLER1 failure group is shifted to the CONTROLLER2 failure group and implicit rebalancing is triggered.
- The ASM does not mirror any data and newly allocated primary allocation units (AU) are stored in the CONTROLLER2 failure group.
