QUESTION NO: 140

Which of the following ALTER DISKGROUP commands does not use V$ASM_OPERATION to record the

status of the operation?

A. ADD DIRECTORY添加目录

B. DROP DISK

C. RESIZE DISK

D. REBALANCE

E. ADD FAILGROUP

Answer: A

A. ADD DIRECTORY添加目录

The ADD DIRECTORY command is not likely to use VASMOPERATIONtotrackitsprogress,becausethisoperationaddsonlyasmallamountofmetadata—adirectoryobject—tothediskgroupandtakesaminimalamountoftimetocomplete.TheVASM OPERATION view provides the status of long-running

ASM operations. “ 添加目录” 命令是不太可能使用ASM操作来跟踪其进展情况，因为这种操作仅增加少

量的元数据–目录对象–到磁盘组，花费少量的时间来完成。 ASM操作视图提供了长时间运行的ASM操作的

状态。
