NEW QUESTION 6
You plan to partition the database and storage grids in an X5-2 full rack, creating two clusters and two storage grids without using virtualization.
One cluster will be used for production and should consist of six database servers and nine storage servers.
The other cluster will be used for test and development, and should consist of two database servers and five storage servers.
The storage must be partitioned so that the storage servers are visible only to the appropriate database servers that are meant to access them.
What must be done to achieve this?

  • A. Configure Exadata realms using Oracle ASM-scoped security mode.
  • B. Configure Exadata realms using Database –scoped security mode.
  • C. Edit the CELLI
  • D. ORA file on each database server to contain IP addresses of storage servers in the storage grid associated with the cluster to which that database server belongs.
  • E. Edit the CELLINI
  • F. ORA file on each database server to contain IP addresses of storage servers in the storage grid associated with the cluster to which that database server belongs.
  • G. Edit the CELLI
  • H. ORA file on each database server to contain IP addresses of database servers which are allowed access to specific storage servers in the same storage grid.
  • I. Edit the CELLI
  • J. ORA file on each storage server on contain IP addresses of database servers in the database server grid that are associated with the storage grid to which that storage server belongs.

Answer: C

Explanation:
The cellinit.ora file is host-specific, and contains all database IP addresses that connect to the storage network used by Oracle Exadata Storage Servers. This file must exist for each
database that connect to Oracle Exadata Storage Servers.
The cellinit.ora file contains the database IP addresses. The cellip.ora file contains the storage cell IP addresses. Both files are located on the database server host.

NEW QUESTION 7
Which two statements are true regarding the use of Auto Service Request (ASR) with an X6 Database Machine?

  • A. The database server ILOMs must use SMTP over the management network for notifications to ASR Manager.
  • B. The database server ILOMs must have SNMP traps configured to use the management network for notifications to ASR Manager.
  • C. The storage server ILOMs must have SNMP traps configured to use the management network for notifications to ASR Manager.
  • D. The database server MS process must have SNMP traps configured to use the management network for notifications to ASR Manager.

Answer: BC

Explanation:
B: Database Server ILOM plug-in
Monitoring databases and their instances, ASM environments, the Grid Infrastructure, and the host software environment are done by Enterprise Manager in the usual way as these are standard targets. But monitoring the hardware for the database servers requires the ILOM plug-in, as there is no Management Server (MS) on the database servers to receive SNMP traps from the ILOM. The plug-in will receive sensor state and availability data from the ILOM including alerts based on pre-set ILOM thresholds.
C: Exadata Storage Server plug-inextends the monitoring of exadata cells in addition to providing a GUI interface. The plug-in uses an SSH connection to the cellmonitor user on the cells and uses list commands only. This is for interactive monitoring. One may also set thresholds using the plug-in which are distinct from any thresholds set using cellcli utility as the celladmin user. For alerts to be sent to the plug-in, SNMP traps are used as follows:
Cell ILOM alerts are sent to the cell Management Server (MS) via an SNMP trap. The MS then send SNMP notifications onward to the plug-in.
Cell alerts flagged by MS itself, such as cell thresholds being exceeded, or ADR software alerts, are sent to the plug-in using SNMP.

NEW QUESTION 8
In which three situations will a Smart Scan occur on a table for which Smart Scan is possible, assuming that nothing in the environment prevents a Smart Scan?

  • A. The ASM diskgroup containing the table’s tablespace has a 4 MByte AU size.
  • B. Executing queries in parallel.
  • C. setting serial_direct_read= true in the session issuing the SQL statements and executing a serial query.
  • D. Having direct path reads used at execution time.
  • E. An update to the table is made identifying the row to be modified by primary key.
  • F. An index range scan occurs for the table.

Answer: BCD

Explanation:
Whether you get a direct path read & smart scan, depends on the current buffer cache size, how big segment you’re about to scan and how much of that segment is actually cached at the moment. This dynamic decision unfortunately can cause unexpected surprises and variance in your report/batch job runtimes.
To work around these problems and force a direct path read/smart scan, you can either: D: One of the most common Exadata performance problems is that the direct path reads
(and thus also Smart Scans) don’t sometimes kick in when running full scans in serial
sessions.
Note: Smart Scan is a subset of Cell Offload Processing and is perhaps the feature that is most highly associated with Exadata. Smart Scan allows Oracle databases to push query information down to the storage level, specifically:

NEW QUESTION 17
You plan to migrate a database supporting an OLTP workload to your new X5 Database Machine.
The current database instance supports a large number of short duration sessions and a very high volume of short transactions.
Which three X5 Database Machine features can improve performance for this type of workload?

  • A. An improved highly efficient undo and redo architecture
  • B. Faster optimization due to an Exadata-specific optimizer
  • C. Reduced I/O latency for writes due to writeback flashcache on all Exadata X5 and later models
  • D. Ultra high I/O performance for reads and writes when using Exadata Extreme Flash in X5 and later models
  • E. Reduced I/O latency for reads due to read flashcache on all Exadata X5 and later models

Answer: ACD

Explanation:
A: To further accelerate OLTP workloads, the Exadata Smart Flash Cache also implements a special algorithm to reduce the latency of log write I/Os called Exadata Smart Flash Logging.
C: Use the Write-Back Flash Cache feature to leverage the Exadata Flash hardware and make Exadata Database Machine a faster system for Oracle Database Deployments.
D: Exadata X5-2 introduces Extreme Flash Storage Servers. Each Extreme Flash storage server contains eight 1.6 TB state-of-the-art PCI Flash drives. PCI flash delivers ultra-high performance by placing flash memory directly on the high speed PCI bus rather than behind slow disk controllers and directors.

NEW QUESTION 18
You issued these commands to all Exadata Storage Servers in an X6 Exadata Database Machine using dcli:
alter iormplan objective = off alter iormplan active
There are no database or category plans defined.
You are suffering I/O performance problems at certain times, which vary by day and week. DSS and batch workloads perform well, but your OLTP workloads suffer poor response
times when running at the same time as these other workloads.
You must ensure that DSS and batch workloads retain relatively high throughput without causing excessive degradation of OLTP performance.
Which statement would you issue to all Exadata Storage Servers to achieve this?

  • A. alter iormplan objective = low_latency
  • B. alter iormplan objective = high_throughput
  • C. alter iormplan objective = balanced
  • D. alter iormplan objective = auto

Answer: A

Explanation:
When the objective option is set to basic, the database resource plan maximum utilization limits are not enforced. For stricter plan conformance, and enforcement of maximum utilization limits, the objective option must be set to something other than basic. The supported IORM objectives are auto, low_latency, balanced, and high_throughput.
The objective may also be changed to low_latency in which case the latency for critical I/Os is very good but there is a significant degradation in scan throughput when both workloads are running concurrently.

NEW QUESTION 19

  • C. the DBFS_DG diskgroup with high redundancy
  • D. mirrored system area on hard disk 0 and hard disk 1
  • E. the RECO_<DBM_Name> ASM diskgroup
  • F. the DATA_<DBM_Name> ASM diskgroup

Answer: CEF

Explanation:
The first two disks of Exadata Storage Server are system disks. Oracle Exadata Storage Server Software system software resides on a portion of each of the system disks. These portions on both system disks are referred to as the system area.
The default configuration on Exadata is to have 3 diskgroups - DATA, RECO, and DBFS_DG.

NEW QUESTION 20
Which two statements are true about Auto Service Request (ASR) with an X5 Database Machine?

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

Answer: AC

Explanation:
A: Oracle recommends that you install Oracle ASR Manager on an external, standalone server.
C: Oracle ASR is designed to generate Oracle service requests automatically when certain types of faults are detected on Oracle products that are qualified for Oracle ASR.
Oracle ASR works only for specific component faults. Most of the common components, such as disks, fans, and power supplies, are covered. However, some components are not covered. For example, Oracle ASR does not cover InfiniBand events; there are specific images and specific InfiniBand switch firmware that you must use. You cannot upgrade these components independently.
