It transfers statistics from memory to disk at regular intervals.
It coordinates the rebalance activity for disk groups when ASM is used.
It communicates with the Automatic Storage Management (ASM) instance on behalf of the databaseinstance.
It performs dynamic memory management when Automatic Shared Memory Management is enabledfor the database instance.
第1题:
You administer an online transaction processing (OLTP) system whose database is stored in AutomaticStorage 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 failurehappens 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.
第2题:
Which two are the uses of the ASM metadata backup and restore (AMBR) feature?()
第3题:
A. CKPT
B. SMON
C. MMON
D. DBWR
第4题:
You are managing an Oracle 11g database with ASM storage, for which the COMPATIBLE initialization parameter is set to 11.1.0. In the ASM instance, the COMPATIBLE.RDBMS attribute for the disk group is set to 10.2 and the COMPATIBLE.ASM attribute is set to 11.1. Which two statements are true in this scenario for the features enabled for ASM? ()
第5题:
Which two statements are true regarding an Automatic Storage Management (ASM) instance? ()
第6题:
A. The metadata used to track extents in SGA is reduced.
B. Rebalance operations are completed faster than with a fixed extent size
C. An ASM Instance automatically allocates an appropriate extent size.
D. Resync operations are completed faster when a disk comes online after being taken offline.
E. Performance improves in a stretch cluster configuration by reading from a local copy of an extent.
第7题:
What is the net effect of the following command?() alter diskgroup dgroup1 drop disk abc;
第8题:
A. As ASM instance mounts an ASM control file
B. An ASM instance uses the ASMB process for rebalancing of disks within a disk group
C. Automatic Memory Management is enabled in an ASM instance even when the MEMORY_TARGET parameter is not set explicitly
D. An RDBMS instance gets connected to an ASM instance using ASMB as a foreground process when the database instance is started
第9题:
Which statement is true about the Manageability Monitor (MMON) background proces()
第10题:
