Examine the parameters:

Users complain that their sessions for certain transactions hang. You investigate and discover that some users fail to complete their transactions, causing other transactions to wait on row-level locks.
Which two actions would you take to prevent this problem? (Choose two.)

B.Set a limit in the profiles of blocking users to control the number of data blocks that can be accessed in a session.

C.Increase the maximum number of ITL slots for segments on which a blocking user performs a transaction.

D.Decrease the SESSIONS_PER_USER limit in the profiles assigned to blocking users.

E.Use Database Resource Manager to automatically kill the sessions that are idle and are blocking other sessions.

Question 182

The characteristics of the CDB are as follows:
- Version: Oracle Database 12c Release 1 64-bit
- Character set: AL32UTF8
- O/S:OracleLinux 6 64-bit
Which technique should you use to minimize down time while plugging this non-CDB into the CDB?

A.Transportable database

B.Transportable tablespace

C.Data Pump full export / import

D.The DBMS_PDB package

E.RMAN

Question 183

You want to schedule a job to rebuild a table's indexes after a bulk insert, which must be scheduled as soon as a file containing data arrives on the system.
What would you do to accomplish this?

A.Create a file watcher and an event-based job for bulk insert and then create another job to rebuild indexes on the table.

B.Create a file watcher for the bulk inserts and then create a job to rebuild indexes.

C.Create a job array and add a job for bulk insert and a job to rebuild indexes to the job array.

D.Create an event-based jobfor the file arrival event, then create a job for bulk insert, and then create a job to rebuild indexes.

Question 184

You are using RMAN to back up your database. All the data files are in read/write mode.
Examine the RMAN configuration parameters:

Which two statements are true about a whole consistent backup of a database running in ARCHIVELOG mode? (Choose two.)

B.The database instance must be shut down to take the backup.

C.The backup consists of blocks that have been formatted.

D.The backup can be used as an incremental level 0 backup.

E.The database must be in MOUNT state to take the backup.

Question 185

Your production database uses file system storage. You want to move storage to Oracle Automatic Storage Management (ASM).
How would you achieve this?

A.by using a transportable database

B.by using the Database Upgrade Assistant (DBUA)

C.by using Data Pump

D.by using RMAN
