The Exadata compute node, exadbs04, has been having issues for some time. The server had to be repaired and you just received a new server. Your LVM snapshot was corrupt and now the compute node must be re-image with an Oracle Support installation image. Which three tasks would you need to perform to re-image the compute node?
A. Mount the LVM backup image across the network and recover the system.
B. Remove exadbs04 from the RAC cluster and all associated Oracle Homes from the central inventory.
C. Create a CELLBOOT USB Flash Drive using an external USB drive.
D. Reboot the new server using a bootable recovery image from the external USB drive.
E. Reconfigure all site-specific settings (host name, IP addresses, NTP server, and so on).
You are asked to enable Write Back Flash Cache for one of your customers X3-2 Full Rack in a rolling fashion. Put the following steps in the right order:
A) Set flashCacheMode to writeback.
B) Inactivate all grid disks and shut down cellsrv.
C) Drop the Flash Cache.
D) Verify that cell for flashcacheMode is writeback.
E) Create the Flash Cache.
F) Start up cellsrv and activate all grid disks.
G) Check grdidksk asmdeactivationoutcome and asmmodestatus for all grid disks to ensure that all grid disks on all cells are set to Yes and online, respectively.
A. G. B, C, A, F, E, D, and G
B. G, A, B, C, F, E, D, and G
C. G, C, B, A, F, E, D, and G
D. G, E, C, B, F, A, D, and G
A customer has three databases named CC. FIN, and DW. The CC database is for their CallCenter. Even a slight decrease in the response time of the database would mean more people “on hold” in their data center. The orders received through the CallCenter are stored in the Finance (FIN) database. Both databases, CC and FIN, serve as sources for the Data Warehouse (DW) database. All databases use the same Automatic Storage Management (ASM) diskgroup and therefore, the same physical disks on Exadata storage. The customer wants to dynamically control the resources that are available for the CallCenter database because this has direct impact on their operations?
Which option should be implemented?
A. DBRM on the CC database
B. DBRM on all the databases
C. IORM, because DBRM cannot be changed for an existing session
D. IORM and DBRM
Consider the following software changes that are performed manually on a Linux server:
1. Changes for Linux kernel firewall configuration
2. Changes for custom performance monitoring tools
3. Changes for security scan tools
4. Changes for Linux system performance optimization
Which of the software changes listed are permitted on Exadata Storage Servers?
A. 1, 2, 3, and 4
B. only 3 ‘
D. only 2
E. only 1 and 2
F. only 2 and 3
1: The Storage Server Patch is responsible for keeping our cell nodes always up-to-date, fixing possible problems, and this patch includes different component patches, like kernel patches, firmware, operation system, etc… for the Storage Server.
3,4: security scan tools changes and Linux system performance optimization changes would be on the database server.
Which two statements are true about enabling write-back flash cache?
A. When enabling write-back flash cache in a non rolling manner, it is important to ensure that asmdeactivatonoutcome is set to YES and asmModestatus is set to ONLINE for all grid disks.
B. Before using write-back flash cache, you need to verify the minimum required versions.
C. Before write back-flash cache is enabled, you need to drop the Flash Cache first.
D. The setting flashCacheMode should be set to writeback by updating cellinit.ora and restarting cellsrv.
E. When enabling write-back flash cache in a rolling manner, dcli should be used to inactivate the grid disks on all cells first.
Answer: B, C
B: Exadata storage version 18.104.22.168.1 is the minimum version required to use this write back flash cache option.
C: Steps for Enabling Write back flash cache:
First of all, you don’t need the stop CRS or database (This is ROLLING method) ,you can do it cell by cell.
* drop flashcache
* Be sure asmdeactivationoutcome is YES is before disabling grid disk
Consider the following setup:
User A1 belongs to resource group High on Database A.
User B2 belongs to resource group Low on Database B.
User C3 is a user on Database C without any DBRM setup.
Database A: Resource group High gets 80% and Low gets 20%.
Database B: Resource group High gets 60% and Low gets 40%.
Database A: Share=20, limit=5
Database B: Share=30, limit=10
Database C: 5 shares
Total number of shares in the IORM setup = 100
What percent of I/O will each database user theoretically be using when the Exadata storage unit I/O throughout is used 100% and no other databases but A, B, and C are running?
A. Al = 36%, B2=18%, and C3=9%
B. Al = 33%, B2=33%, and C3=33%
C. AI = 10%, B2=5%, and C3=20%
D. Al = 8%, B2=12%, and C3=5%
E. Al = 5%, B2=10%, and C3=85%
