A. ARCHIVE HIGH

B. QUERY HIGH

C. BASIC

D. ARCHIVE LOW

E. OLTP

A. Swap hard disks to High Capacity disks.

B. Tune the application to reduce I/O requests.

C. Enable Write-Back Flash Cache due to heavy LGWR usage.

D. Enable Write-Back Flash Cache due to heavy DBWR usage.

E. LeverageIORM to give priority to critical workloads.

A. Before patching cells in a rolling manner, you must check asmdeactivationoutcome amModestatus and make sure that cells on all disks are online and that disks can be deactivated.

B. Backing up database servers and storage cells is not recommended before performing planned maintenance.

C. Patching should never be interrupted due to a connection drop. It is therefore recommended that you use VNC or the screen utility.

D. It is recommended that Exadata systems with Data Guard configured use the "Standby First" patching approach.

E. Database server updates can be rolled back using the the "yum downgrade" procedure.

F. Bundle patches do not require testing before being installed on a production system.

A. Mount the LVM backup image across the network and recover the system.

B. Reconfigure all site-specific settings (host name, IP addresses, NTP server, and so on).

C. Remove exadbs04 from the RAC cluster and all associated Oracle Homes from the central inventory.

D. Reboot the new server using a bootable recovery image from the external USB drive.

E. Create a CELLBOOT USB Flash Drive using an external USB drive.

A. Insert as Select

B. Data Pump Export and Import

C. Data Guard

D. transportable tablespaces

E. transportable database

A. The Oracle Database software on Exadata is updated using standard OPatch and the Oracle Universal Installer.

B. Rolling patching is faster than non-rolling patching, but database down time is longer.

C. The Oracle Database patchset software (for example, 11.2.0.3) requires the Exadata-specific version.

D. Storage server updates require access to an Unbreakable Linux Network (ULN) based repository.

E. The database server operating system software (other than kernel and OFED) may be installed or updated from non-Exadata sources

F. Running Exadata with different storage server software versions is supported, but should be minimized to rolling patching scenarios.

A. Instance caging is the right approach to make sure that database instances are not stealing memory from each other.

B. The CPU Resource Manager and IORM need to be enabled to make instance caging to work as expected.

C. The init.org parameter resource_manager_plan should be set.

D. For a system with 16 threads, the sum of cpu_count for all databases should not be higher than 32 to prevent oversubscribing

E. Database instances need to be restarted to make changes to cpu_count effective.

A. No manual action is required because Automatic Storage Management (ASM) fast mirror resync is automatic

B. Replace the disk and run MegaCLI to rebuild the degenerate mirror.

C. Run RMAN REPAIR FAILUR

D. No manual action is required because ASM rebalancing isautomatic.

E. Replace the disk and manually copy the mirror extents to the new drive.
