ORACLE
1. A_____is a collection of all objects that a user has created.
Ans:-Data
2. Which of the oracle authentication mechanism is used to
management of the password for the account?
Ans: Database Account
3. A_______is a set of predefine resource parameter that can
be used to monitor control various database resources.
Ans:
4. PL/Sql is a _______structured language.
Ans: Block
5._______has made PL/SQL code run faster without requiring
any additional work on the part of the programmer.
Ans: Oracle
6. A line of PL/Sql contains groups of characters. Known as
lexical units.
7. There are two kinds of numeric literals can be used in
arithmetic expressions of PL/SQL they are integers and real’s.
8. Boolean literals are the predefined values TRUE and FALSE
and the non-value NULL.
9. The block headers specify whether the PL/SQL block is a
procedure, a function or a package.
10. In PL/SQL iterative control statements, a loop repeats a
sequence of statements.
11. The while loop enables you to evaluate a condition before a
sequence of statements would be executed.
12. The for loop will allow us to execute a block of code
repeatedly until some condition occurs.
13. There are two different types error condition in PL/SQL.
Unit-2
1. In PL/SQL function can be called by using ______
Ans: NAME
2. In PL/SQL procedure declaration resembles a function
declaration exempt that there is no DATA TYPE.
3. Triggers are used to define code that is executed fired when
certain action or event occur.
4. REPLACE is used to recreate if trigger already exists.
5. Cursors are PL/SQL constructs that enable you to process,
one row at a time that results of a multi row query.
6. There are two types of cursors, vise implicit cursors and
explicit cursors.
7. The data that is stored in the cursor is called the active data
set.
8. Opening a cursor executes the query and identifies the active
set that contains all the rows which meet the query search
criteria.
9. In the explicit cursor attributes of PL/SQL %found evaluates
to true when last fetch succeeded.
10. A package is a database object that groups logically
related.PL/SQL type’s object and subgroup-programs.
11. In PL/SQL the package specification contains Public
declarations.
12. The package body implements the package specification.
Unit-3
1. A database is a centralized repository of organization data.
2. Oracle 9i database product is made up three main
components.
3. The oracle instance consists of memory components of
oracle and various background processes.
4. In oracle 9i there are two types of initialization files namely
SPFILE and PFILE.
5. The oracle instance is made up of the system global area and
the background process.
6. In SGA circular buffer that stores all changes made in the
database is called as REDO LOG BUFFER.
7. In SGA the contents of the memory are shared by multiple
users is called as Shared pool.
8. The background process of the oracle instance is responsible
for performing Asynchronous I/O.
8. The PGA is used to process SQL statement and to hold logon
and other session
9. DATA FILE contain the data dictionary and user created data.
10. The control file keeps a record of the names, size and
location different physical files of the data.
11. REDO entries can be used to recover the database in the
event of the instance failure.
12. Password file is used to hold the name, of privileged users
who have been granted the SYDBA and SYSOPER roles.
13. starting up a database should be done by a privileged user.
14. during a proper shutdown of oracle database, there phases
________to the startup is performing in reverse order.
Ans: Complimentary
15. The end of the transaction is recorded in the REDO-LOG
