QUESTION 3Exhibit below: Which three statements are true about terminating a session?

A. Without any error, you can terminate the active session by executing:SQL> ALTER SYSTEM KILL SESSION '7, 15';

B. You can terminate the active session by executing:SQL> ALTER SYSTEM KILL SESSION "7, 15';But you also get the error message:ORA-00028: your session has been killed

C. You cannot terminate the active session. You have to wait until that session becomes inactive.

D. Without any error, you can terminate the inactive session by executing:SQL> ALTER SYSTEM KILL SESSION '12, 63';

E. When an inactive session is killed, the status of that session remains visible in VSSESSION with status KILLED. The rowf the terminated session is removedfrom VSSESSION after the user attempts to use the session again.

F. You cannot terminate the inactive session. You have to wait until that session becomes active again.

Correct Answer: BDESection: (none)Explanation

Explanation/Reference:Explanation: B (not A, Not C):* You terminate a current session using the SQL statement ALTER SYSTEM KILL SESSION. The following statement terminates the session whose systemidentifier is 7 and serial number is 15:* Terminating an Active SessionIf a user session is processing a transaction (ACTIVE status) when you terminate the session, the transaction is rolled back and the user immediately receives the


following message:ORA-00028: your session has been killedALTER SYSTEM KILL SESSION '7,15';E (not F): Terminating an Inactive SessionIf the session is not making a SQL call to Oracle Database (is INACTIVE) when it is terminated, the ORA-00028 message is not returned immediately. Themessage is not returned until the user subsequently attempts to use the terminated session.When an inactive session has been terminated, the STATUS of the session in the V$SESSION view is KILLED. The row for the terminated session is removed fromV$SESSION after the user attempts to use the session again and receives the ORA-00028 message.Reference: Oracle Database Administrator's Guide, Terminating SessionsURL: http://docs.oracle.com/cd/B28359_01/server.111/b28310/manproc008.htm#ADMIN11192

Data Redaction provides selective, on-the-fly redaction of sensitive data in query results priorto display by applications so that unauthorized users cannot view the sensitive data. It enablesconsistent redaction of database columns across application modules accessing the same data.Data Redaction minimizes changes to applications because it does not alter actual data ininternal database buffers, caches, or storage, and it preserves the original data type andformatting when transformed data is returned to the application. Data Redaction has noimpact on database operational activities such as backup and restore, upgrade and patch, andhigh availability clusters.Explanation: Reference: Oracle Advanced Security, 12c, Oracle Data Sheet

QUESTION 78Why does performance degrade when many UPDATE, INSERT, or DELETEstatements are issued on a table that has an associated bitmap index?


A. The DML operations re-create the bitmap index blocks.

B. The bitmap index is rebuilt automatically after a DML operation.

C. The smallest amount of a bitmap that can be locked is a bitmap segment.

D. Additional time is taken to remove NULL values from the bitmap index alter a DML operation.


Explanation/Reference:Explanation: Bitmap indexes in currently “supported” versions of Oracle are maintained in a much more efficient manner than they were previously, to the point where the needfor frequently rebuilds has been much reduced, even in tables in which such indexes are not dropped during heavy loads.That said, Bitmap indexes are still unsuitable in OLTP type environments (even in 11g or later) due to the locking implications associated with them.Note: bitmap indexes are only suitable for static tables and materialized views which are updated at nigh and rebuilt after batch row loading.Not B: Like b-tree indexes, bitmap indexes should be rebuilt (ALTER INDEX . . . REBUILD) if there is a lot of DML (UPDATE, INSERT, DELETE) activity.Not A: Since 10g, Oracle is significantly more efficient and where possible will simply adjust the current rowid range of the Bitmap index entry and modify the bitmapstring accordingly to accommodate a new row value (resulting in an overall increase of just 2 bytes overall in this example) rather than create a totally new indexentry (which required an additional 21 bytes in the 9i example).
