NEW QUESTION 46
You execute the following commands to audit database activities:
SQL > ALTER SYSTEM SET AUDIT_TRIAL=DB, EXTENDED SCOPE=SPFILE;
SQL > AUDIT SELECT TABLE, INSERT TABLE, DELETE TABLE BY JOHN By SESSION WHENEVER SUCCESSFUL; Which statement is true about the audit record that generated when auditing after instance restarts?
- A. One audit record is created for the whole session if john successfully executes a SELECT, INSERT, or DELETE command on a table, and contains the execution plan, SQL text, and bind variables used.
- B. One audit record is created for every successful execution of a SELECT, INSERT OR DELETE command on a table, and contains the SQL text for the SQL Statements.
- C. One audit record is created for every successful execution of a SELECT, INSERT OR DELETE command, and contains the execution plan for the SQL statements.
- D. One audit record is created for the whole session if JOHN successfully executes a select command, and contains the SQL text and bind variables used.
- E. One audit record is created for the whole session if john successfully executes a SELECT, INSERT, or DELETE command, and contains the execution plan for the SQL statements.
Answer: B
Explanation:
Note:
* BY SESSION
In earlier releases, BY SESSION caused the database to write a single record for all SQL statements or operations of the same type executed on the same schema objects in the same session. Beginning with this release (11g) of Oracle Database, both BY SESSION and BY ACCESS cause Oracle Database to write one audit record for each audited statement and operation.
* BY ACCESS
Specify BY ACCESS if you want Oracle Database to write one record for each audited statement and operation.
Note:
If you specify either a SQL statement shortcut or a system privilege that audits a data definition language (DDL) statement, then the database always audits by access. In all other cases, the database honors the BY SESSION or BY ACCESS specification.
* For each audited operation, Oracle Database produces an audit record containing this information:
/ The user performing the operation
/ The type of operation
/ The object involved in the operation
/ The date and time of the operation
NEW QUESTION 47
Examine the contents of SQL loader control file:
Which three statements are true regarding the SQL* Loader operation performed using the control file?
- A. The SQL* Loader operation fails because no record terminators are specified.
- B. An EMP table is created if a table does not exist. Otherwise, if the EMP table is appended with the loaded data.
- C. The SQL* Loader operation assumes that the file must be a stream record format file with the normal carriage
return string as the record terminator. - D. The SQL* Loader data file myfile1.dat has the column names for the EMP table.
- E. Field names should be the first line in the both the SQL* Loader data files.
Answer: B,C,D
Explanation:
A: The APPEND keyword tells SQL*Loader to preserve any preexisting data in the table. Other options allow you to
delete preexisting data, or to fail with an error if the table is not empty to begin with.
B (not D):
Note:
* SQL*Loader-00210: first data file is empty, cannot process the FIELD NAMES record
Cause: The data file listed in the next message was empty. Therefore, the FIELD NAMES FIRST FILE directive could not
be processed.
Action: Check the listed data file and fix it. Then retry the operation
E:
* A comma-separated values (CSV) (also sometimes called character-separated values, because the separator
character does not have to be a comma) file stores tabular data (numbers and text) in plain-text form. Plain text
means that the file is a sequence of characters, with no data that has to be interpreted instead, as binary numbers. A
CSV file consists of any number of records, separated by line breaks of some kind; each record consists of fields,
separated by some other character or string, most commonly a literal comma or tab. Usually, all records have an
identical sequence of fields.
* Fields with embedded commas must be quoted.
Example:
1997,Ford,E350,"Super, luxurious truck"
Note:
* SQL*Loader is a bulk loader utility used for moving data from external files into the Oracle database.
