Question 11

Examine the output of the asmcmd and srvct1 commands:

Then you execute this command:

$ srvctl relocate asm currentnode host03 targetnode host02

Which three statements are true regarding the execution of this command based on the output shown?

It fails because an ASM instance is not configured to run on HOST02.

It succeeds and starts an ASM instance on HOST02 and shuts down the ASM instance on HOST03.

It succeeds and 12c database instances connected to the ASM instance on HOST03 can be reconnected to the ASM instance on HOST02.

It fails because the ASM instance has not been shut down first on HOST03.

It succeeds and starts an ASM instance on HOST02 but the ASM instance on HOST03 is not shut down until all connected clients disconnected.

It succeeds and 12c database instances connected to the ASM instance on HOST03 can be reconnected to the ASM instance on HOST01.

Correct Answer: A, B, C

The command will fail because an ASM instance is not configured to run on HOST02. Flex ASM allows ASM instances to run on any node, but the srvctl config output does not show HOST02 as hosting an ASM instance. Normally, the `relocate` operation would succeed by starting an ASM instance on the target node and shutting down the ASM instance on the current node. Also, 12c database instances have the ability to reconnect to a running ASM instance on another node that is part of the same ASM cluster, as seen with HOST01. Therefore, the statements indicating the failure due to configuration, successful relocation and connection failover are correct.

Discussion

JVarelaCOptions: BEF

I think it'2s B,E,F A no; it's a flex cluster and any node can run an ASM instance B yes; it's a relocate, though instance in host03 is shut down before startup of instance in host02 C no; to keep ASM instances cardinality instance in host03 must be shut down before starup instance in host02, so connections are failed over to surviving instance in host01 D no; it's a relocate, the operation itself shuts down instance in host03 E yes; it's not a failure, so shut down it's not completed before moving connections to a surviving instance F yes; for the same reason for C it's not correct
