NEW QUESTION # 60
In the ORCL database, UNDOTBS1 is the active undo tablespace with these properties:
1. A size of 100 MB
2. AUTOEXTEND is off
3. UNDO_RETENTION is set to 15 minutes
4. It has RETENTION GUARANTEE
UNDOTBS1 fills with uncommitted undo 10 minutes after the database opens.
What will happen when the next update is attempted by any transaction?
- A. It succeeds and the least recently written undo block of UNDOTBS1 is overwritten by the generated undo.
- B. It succeeds and the generated undo is stored in SYSAUX.
- C. It succeeds and the generated undo is stored in SYSTEM.
- D. It succeeds and the least recently read undo block of UNDOTBS1 is overwritten by the generated undo.
- E. It fails and returns the error message "ORA-30036: unable to extend segment by 8 in undo tablespace 'UNDOTBS1'".
Answer: E
Explanation:
To guarantee the success of long-running queries or Oracle Flashback operations, you can enable retention guarantee. If retention guarantee is enabled, the specified minimum undo retention is guaranteed; the database never overwrites unexpired undo data even if it means that transactions fail due to lack of space in the undo tablespace. If retention guarantee is not enabled, the database can overwrite unexpired undo when space is low, thus lowering the undo retention for the system. This option is disabled by default.
NEW QUESTION # 61
Which two statements are true about the rules of precedence for operators? (Choose two.)
- A. The concatenation operator | | is always evaluated before addition and subtraction in an expression
- B. The + binary operator has the highest precedence in an expression in a SQL statement
- C. NULLS influence the precedence of operators in an expression
- D. Multiple parentheses can be used to override the default precedence of operators in an expression
- E. Arithmetic operators with equal precedence are evaluated from left to right within an expression
Answer: D,E
Explanation:
Reference:
https://docs.oracle.com/cd/A87860_01/doc/server.817/a85397/operator.htm Precedence is the order in which Oracle evaluates different operators in the same expression. When evaluating an expression containing multiple operators, Oracle evaluates operators with higher precedence before evaluating those with lower precedence. Oracle evaluates operators with equal precedence from left to right within an expression.
