Company.com is migrating from a third party managed disk subsystem to an IBM TotalStorage Enterprise Storage Server. Connection of the new storage server is complete， and it has been tested on all of the nodes in the three node HACMP cluster.  How does the customer migrate to the new storage server with minimum down time？（）

• A、 Shut down one node at a time and let the other node serve the application
• B、 Stop HACMP with the forced option and perform migration of the disks on one node，then restart HACMP
• C、 Stop both nodes and perform the migration all at once using standard AIX commands in parallel， then restart the cluster
• D、 Use C-SPOC to add the new disks to the cluster and migrate the information off the existing disks， then remove the old disks with C-SPOC

You upgraded from a previous Oracle database version to Oracle Database version to Oracle Database12c. Your database supports a mixed workload. During the day, lots of insert, update, and deleteoperations are performed. At night, Extract, Transform, Load (ETL) and batch reporting jobs are run. The ETL jobs perform certain database operations using two or more concurrent sessions.After the upgrade, you notice that the performance of ETL jobs has degraded. To ascertain the cause ofperformance degradation, you want to collect basic statistics such as the level of parallelism, totaldatabase time, and the number of I/O requests for the ETL jobs. How do you accomplish this?（）

• A、Examine the Active Session History (ASH) reports for the time period of the ETL or batch reporting runs.
• B、Enable SQL tracing for the queries in the ETL and batch reporting queries and gather diagnostic data from the trace file.
• C、Enable real-time SQL monitoring for ETL jobs and gather diagnostic data from the V$SQL_MONITOR view.
• D、Enable real-time database operation monitoring using the DBMS_SQL_MONITOR.BEGIN_OPERATION function, and then use the DBMS_SQL_MONITOR.REPORT_SQL_MONITOR function to view the required information.

第14题：

The customer has implemented an SNMPP based network monitoring tool and wishes to monitor chang3es in the cluster. The general status of the cluster is gathered via SNMP but the poling time to retrieve the status is too slow for immediate reaction to serious issues. There is a technical reason why the polling time cannot be changed.  How can HACMP report changes in its status on a more timely basis？（）  

• A、 Create a pre/post event script to report errors more rapidly.
• B、 Edit SNMP configuration file to send traps for cluster state changes.
• C、 Change the option in "SRC" to enable trap mode for the "clinfo" process.
• D、 Use the "monitor" pre-event facility in HACMP to send information to the monitoring device.

An administrator has had a request from the data center for method to monitor the status of an  HACMP cluster. The monitoring software environment currently used is not compatible with SNM at this time， and there is not time to crate a new tool. There is also a restriction that the data center personnel not be allowed to login to the HACMP cluster nodes. What method will provide the solution for customer？（）  

• A、 The clstat.cgi program will provide a solution.
• B、 The customer must install Tivoli with the HACMP plugin for monitoring the cluster.
• C、 The clinfo program included in the HACMP distribution will solve the monitoring issues.
• D、 Customize the cluster to send error notifications for every event to an email at the network control center.
