In-Depth Information
4. A user named Arren is executing this query:
select table_name, operation, undo_sql
from
flashback_transaction_query t,
(select versions_xid as xid
from employees versions between scn minvalue
and maxvalue
where employee_id = 123) e
where t.xid = e.xid;
When the query runs, he receives an ORA-01031: insufficient privileges error.
Since the user owns the employees table, you know that it is not the problem. Which
of the following SQL statements will correct this problem?
A. GRANT SELECT ANY TRANSACTION TO ARREN;
B. GRANT SELECT ON FLASHBACK_TRANSACTION_QUERY TO ARREN;
C. GRANT SELECT_ANY_TRANSACTION TO ARREN;
D. GRANT FLASHBACK TO ARREN;
E. GRANT SELECT ANY VIEW TO ARREN;
5. AUM has been retaining about 15 minutes' worth of undo. You want to double the
retention period but not at the expense of new transactions failing. You decide to alter
the system to set the parameter UNDO_RETENTION=18000 . However, AUM still retains
only about 15 minutes' worth of undo. What is the problem? (Choose the best answer.)
A. You need to alter the undo tablespace to add the RETENTION GUARANTEE setting.
B. You need to increase the size of the undo tablespace.
C. The undo tablespace is not set to autoextend.
D. You need to alter the Recycle Bin to add the RETENTION GUARANTEE setting.
6. In order to perform Flashback Transaction Query operations, which of these steps are
required? (Choose all that apply.)
A. Ensure that the database is running with version 10.1 or greater compatibility.
B. Enable Flashback Logging.
C. Enable Supplemental Logging.
