Question 3 of 71

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?

DBRM on all the databases

IORM, because DBRM cannot be changed for an existing session

Question 5 of 71

Which two statements are true about enabling write-back flash cache?

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.

Before using write-back flash cache, you need to verify the minimum required versions.

Before write back-flash cache is enabled, you need to drop the Flash Cache first.

The setting flashCacheMode should be set to writeback by updating cellinit.ora and restarting cellsrv.

When enabling write-back flash cache in a rolling manner, dcli should be used to inactivate the grid disks on all cells first.

Correct Answer: B, C
