Most 9 Interview Tips For your Next interview Success
1.While you're the one being evaluated, don't forget
to size up the interviewer as well. You don't want to point out her flaws, but

make sure that they are a leader that can handle inevitable change,"
Williams says.
2.Be on time, turn off your cell phone, and don't
interrupt. You could have all the proper qualifications, but someone else may
as well. The difference will come down to the details. If your cell phone
starts playing "Jingle Bells," the job could go to the other guy.
"Anyone's appearance, demeanor, timeliness... are checkmarks," says
Gerard Ferro, CEO of SunRx.

Database Security & Administration
97. What is user Account in Oracle database?
A user account is not a physical structure in database but it is having important relationship to the objects in the database and will be having certain privileges.
98. How will you enforce security using stored procedures?
Don't grant user access directly to tables within the application.
Instead grant the ability to access the procedures that access the tables.
When procedure executed it will execute the privilege of procedures owner. Users cannot access tables except via the procedure.
99. What are the dictionary tables used to monitor a database space?
DBA_FREE_SPACE
DBA_SEGMENTS
DBA_DATA_FILES.
SQL*Plus Statements
100. What are the types of SQL statement?
Data Definition Language: CREATE, ALTER, DROP, TRUNCATE, REVOKE, NO AUDIT & COMMIT.
Data Manipulation Language: INSERT, UPDATE, DELETE, LOCK TABLE, EXPLAIN PLAN & SELECT.
Transactional Control: COMMIT & ROLLBACK
Session Control: ALTERSESSION & SET ROLE
System Control: ALTER SYSTEM.
101. What is a transaction?
Transaction is logical unit between two commits and commit and rollback.

64. What is Database Buffers?
Database buffers are cache in the SGA used to hold the data blocks that are read from the data segments in the database such as tables, indexes and clusters DB_BLOCK_BUFFERS parameter in INIT.ORA decides the size.
65. What is dictionary cache?
Dictionary cache is information about the database objects stored in a data dictionary table.
66. What is meant by recursive hints?
Number of times processes repeatedly query the dictionary table is called recursive hints. It is due to the data dictionary cache is too small. By increasing the SHARED_POOL_SIZE parameter we can optimize the size of data dictionary cache.

39. What is a data segment?
Each non-clustered table has a data segment. All of the table's data is stored in the extents of its data segment. Each cluster has a data segment. The data of every table in the cluster is stored in the cluster's data segment.
40. What is an index segment?
Each index has an index segment that stores all of its data.

251. What is renderer
A Java class that can render the output for a set of JavaServer Faces UI components.
252. What is request-response messaging
A method of messaging that includes blocking until a response is received.
253. What is resource adapter
A system-level software driver that is used by an EJB container or an application client to connect to an enterprise information system. A resource adapter typically is specific to an enterprise information system. It is available as a library and is used within the address space of the server or client using it. A resource adapter plugs in to a container. The application components deployed on the container then use the client API (exposed by the adapter) or tool-generated high-level abstractions to access the underlying enterprise information system. The resource adapter and EJB container collaborate to provide the underlying mechanisms-transactions, security, and connection pooling-for connectivity to the enterprise information system.

201. What is normalization
The process of removing redundancy by modularizing, as with subroutines, and of removing superfluous differences by reducing them to a common denominator.
For example, line endings from different systems are normalized by reducing them to a single new line, and multiple whitespace characters are normalized to one space.
