A

 When a file is created in DGROUP1 with the template， it would have three-way mirroring.

B

Which backup jobs should you create? （）

  • A、·a normal backup to disk everyday ·a normal backup to tape on Friday ·a differential backup to tape on Sunday, Tuesday, and Thursday
  • B、·a normal backup to disk everyday ·a normal backup to tape on Friday ·an incremental backup to tape on Sunday, Tuesday, and Thursday

第6题：

You are an Oracle DBA responsible for an ASM instance. The disk controller on your system fails. You suspect that the disk itself is okay. You know it will take 24 hours to replace the controller and you don’t want to have to rebuild the disks from scratch.  What do you do？（）  

  • A、 Take the whole disk group offline and wait for the controller card to be installed. Once it’s installed，bring the disk group online again.
  • B、 Change the ASM parameter ASM_PREFERRED_READ_FAILURE_GROUPS to indicate that you want to read from the non-failed disk. Once the disk controller is replaced，reset the parameter to  its original value.
  • C、 You have no choice but to rebuild the disk. Drop the disk from the disk group and wait for the controller to be replaced. Once the controller is replaced， add the disk back into the disk group and allow ASM to rebuild it.
  • D、 If you are using any setting other than REDUNDANCY EXTERNAL for your disk group，you will have to recover any data on that disk from a backup. The database will be unavailable until you can  correct the problem and perform recovery.
  • E、 Change the attribute DISK_REPAIR_TIME on the disk group to a time greater than 24 hours.

In your Automatic Storage Management （ASM） instance， one of the nonempty disk groups， DGROUP1， is no longer required and you want this disk group to be removed. You execute the following command to achieve this objective：  DROP DISKGROUP dgroup1 EXCLUDING CONTENTS；  What would be the result of this command？（）

  • A、 This command would result in an error because the disk group is not empty.
  • B、 The command would distribute the contents of the specified disk group among all other disk groups and then drop the specified disk group.
  • C、 The command would result in the contents being moved to the parent disk group and dropping of the disk group.
  • D、 The command would result in the disk group being marked as INVALID because it cannot be dropped.
  • E、 The command would drop the disk group， ignoring the EXCLUDING CONTENTS option.

多选题
You administer an online transaction processing (OLTP) system whose database is stored in Automatic Storage Management (ASM) and whose disk group use normal redundancy. One of the ASM disks goes offline, and is then dropped because it was not brought online before DISK_REPAIR_TIME elapsed. When the disk is replaced and added back to the disk group, the ensuing rebalance operation is too slow. Which two recommendations should you make to speed up the rebalance operation if this type of failure happens again?（）
A

Increase the value of the ASM_POWER_LIMIT parameter.

B

Set the DISK_REPAIR_TIME disk attribute to a lower value.

C

Specify the statement that adds the disk back to the disk group.

D

Increase the number of ASMB processes.

E

Increase the number of DBWR_IO_SLAVES in the ASM instance.
