質問 # 17
Which three statements are true about Oracle Configuration Manager (OCM) for an Exadata Database Machine?

  • A. Collected configuration information can be uploaded manually to Oracle.
  • B. It collects configuration information on demand.
  • C. Collected configuration information can be uploaded automatically to Oracle.
  • D. It is mandatory to install OCM on at least one database server.
  • E. It collects configuration information automatically.
  • F. It is mandatory to install OCM on all database servers.

正解:B、C、E

解説:
It collects configuration information automatically (B). OCM gathers detailed configuration information about a variety of designated Oracle products and components across an enterprise on a regular basis2.
It collects configuration information on demand . OCM can also collect configuration information manually when requested by the user or by Oracle Support2.
Collected configuration information can be uploaded automatically to Oracle (E). OCM can upload the collected configuration information to My Oracle Support automatically for analysis and support purposes3.

Which three steps are required to expand an Exadata X9M-2 Database Server with the lowest memory configuration available to the highest memory configuration?

  • A. Add 12x 32GB DIMMs.
  • B. Add 32x 64GB DIMMs.
  • C. Add 24x 32GB DIMMs.
  • D. Add 16x 64GB DIMMs.
  • E. Remove existing memory modules.
  • F. Shutdown the Database Server if running.
  • G. Memory cannot be expanded on Exadata X9M-2 Database Servers.
  • H. Add 16x 32GB DIMMs.
  • I. Add 12x 64GB DIMMs.

正解:D、E、F

解説:
1. Remove existing memory modules: Before adding new memory modules, the existing memory modules should be removed.
2. Add 16x 64GB DIMMs: The new DIMMs should be added, in this case is 16 DIMMs of 64GB each, which will expand the memory to the highest configuration available.
3. Shutdown the Database Server if running: The Database Server should be shutdown before adding new memory modules in order to prevent any possible data loss or corruption.
The steps required to expand an Exadata X9M-2 Database Server with the lowest memory configuration available to the highest memory configuration are as follows:
Shutdown the Database Server if running.
Remove existing memory modules.
Add 16x 64GB DIMMs.
For reference, the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book states that "the lowest memory configuration for the Exadata X9M-2 Database Servers is 384GB and the highest is 768GB [1]. The memory upgrade is done in increments of 64GB using 16x 64GB DIMMs".


質問 # 19
You want to monitor how a large production table is accessed. Especially, you are interested to see how the access on that particular table leverages the benefits of the Exadata Platform.
Which two actions are NOT appropriate for that purpose?

  • A. You run the CellCli-command list activerequest , filtering for the attributes ioReason and objectNumber, that you specify as 'Smart Scan' and the Object ID of your table from DBA_OBJECTS.
  • B. YOU query VSSYSTEM_EVENTS and filter for the event 'cell physical IO interconnect bytes returned by smart scan', associated to your table.
  • C. You query v$SYSTAT and filter for the statistic 'cell smart table scan', associated to your table.
  • D. You query v$segment_statistics and filter for the Object ID of your table from dba_objects and the the column STATISTIC_NAME='optimized physical reads'.

正解:B、C

解説:
1. Querying VSSYSTEM_EVENTS for the event 'cell physical IO interconnect bytes returned by smart scan' will not be appropriate for monitoring the access on a particular table. The V$SYSTEM_EVENT view is used to monitor system-wide performance statistics, not specific table access. C. Querying v$SYSTAT for the statistic 'cell smart table scan' will not be appropriate for monitoring the access on a particular table as well. The v$SYSTAT view contains system-wide performance statistics, not specific table access.


質問 # 20
I/O performance of the prod database on your Exadata Database Machine has degraded slightly over the past month. The database has been allocated to the OLTP I/O Resource Management (IORM) category.
Which two monitoring tools might be useful in examining I/O performance for the prod database?

  • A. I/O-specific dynamic performance views such as v$iostat_fiie, v$iostat_function, and v$iostat_consumer_group from the prod database instances using SQL *p1us
  • B. OS I/O metrics using Enterprise Manager host pages for the storage servers
  • C. OS I/O metrics using OS tools such as iostat on the database servers
  • D. OS I/O metrics using OS tools such as iostat on the storage servers
  • E. cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk

正解:A、E

解説:
According to the Oracle documentation1, two monitoring tools that might be useful in examining I/O performance for the prod database are:
cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk (D). This tool can help you monitor the I/O Resource Management (IORM) metrics and identify any bottlenecks or imbalances in the storage layer.
I/O-specific dynamic performance views such as v$iostat_fiie, v$iostat_function, and v$iostat_consumer_group from the prod database instances using SQL *plus. These views can help you monitor the I/O activity and latency at the file, function, and consumer group level.


質問 # 21
Which two statements are true about Auto Service Request (ASR) with an Exadata Database Machine?

  • A. ASR can upload configuration metadata to support problem resolution.
  • B. ASR Manager must be installed and configured on one of the database servers.
  • C. ASR communicates with Oracle support services using HTTPS.
  • D. ASR Manager opens a service request (SR) automatically after sensors detect hardware faults.
  • E. ASR Manager must be installed and configured on a dedicated server external to the Database Machine.
  • F. Configuring ASR is mandatory for all Database Machine assets.

正解:B、E
