Introduction
 Oracle 11g is a new software of Database released
by Oracle at 2007. 7. 12
 Oracle 11g has more than 400 functions
 The testing hours reach 15 million for it
 Oracle 11g has lots of new functions than former
versions
How to install Oracle 11g
 Download Oracle 11g from internet
 Choose the basic way to install Oracle 11g

 Finish installing
Enter the Database by web page
Create a new Database
 We use Database Configuration Assistant to create a
new database
Create a new Database
 The first step - choose the option you want
Create a new Database
 The second step – choose the database module
Create a new Database
 The third step – name your Database
Create a new Database
 Step four – deploy enterprise manager
Create a new Database
 Step five - set the password
Create a new Database
 Step six - Set the storage function

 Step fourteen – create Database
The difference between 11g and former ones
 Before Oracle 10g, we must install a client-side on
the customer’s computer
 For Oracle 10g and 11g, we can operate the database
on the web page. So we don’t need to install a clientside on each computer
 The defect in my opinion is that it’s not convenient
for us to use the web page, so I advice we use the
software “Toad for Oracle”
The basic use of Oracle 11g
 Like access, we can use it to create table, insert data
modify data and save it
Create table
Insert data
Select data
The advanced functions of Oracle 11g
 1. Database Replay
 You can use Database Replay to capture a workload on the production
system and replay it on a test system with the exact timing, concurrency,
and transaction characteristics of the original workload. This enables you
to test the effects of a system change without affecting the production
system.
 Step 1. On the production system, capture the workload into capture files
 Step 2. Copy the capture files to the test system and preprocess them
 Step 3. On the test system, replay the preprocessed files
 Step 4. Using the reports generated by Database Replay, perform
detailed analysis of both the workload capture and workload replay

 2. SQL Plan Management
 SQL plan management is a preventative mechanism that records and
evaluates the execution plans of SQL statements over time, and builds
SQL plan baselines composed of a set of existing plans known to be
efficient.
 The SQL plan baselines are then used to preserve performance of
corresponding SQL statements, regardless of changes occurring in the
system.

 3. Automatic Diagnostic Repository (ADR)
 The ADR is a file-based repository for database diagnostic data
such as traces, dumps, the alert log, health monitor reports, and
more.
 It has a unified directory structure across multiple instances and
multiple products.

 4. Incident Packaging Service
 A DBA can automatically and easily gather all diagnostic data
(traces, health check reports, SQL test cases, and more)
pertaining to a critical error and package the data into a zip file
suitable for transmission to Oracle Support.
The advanced functions of Oracle 11g
 5. Automatic SQL Tuning Advisor
 Oracle Database automatically runs the SQL Tuning Advisor on selected
high-load SQL statements from the Automatic Workload Repository
(AWR) that qualify as tuning candidates.
 Once automatic SQL tuning begins, the following steps are performed:
 1. Identify SQL candidates in the AWR for tuning.
 2. Tune each SQL statement individually by calling the SQL Tuning
Advisor.
 3. Test SQL profiles by executing the SQL statement.
 4. Optionally implement the SQL profiles provided they meet the criteria
of threefold performance improvement.

 6. Automatic Shared Memory Management
 Automatic Shared Memory Management simplifies the
configuration of the SGA(System Global Area ).
 In response to the workload on the system, the automatic SGA
management distributes the memory appropriately for the
following memory pools:
•
•
•
•
•
Database buffer cache (default pool)
Shared pool
Large pool
Java pool
Streams pool

 7. Database Resource Manager
 The Database Resource Manager solves many resource allocation
problems that an operating system does not manage so well:
•
•
•
•
•
Excessive overhead
Inefficient scheduling
Inappropriate allocation of resources
Inability to man
age database-specific resources
 With the Database Resource Manager, you can do the following:
• Guarantee certain users a minimum amount of processing resources
regardless of the load on the system and the number of users
• Distribute available processing resources by allocating percentages of
CPU time or I/O requests per second to different users and applications

 8. Securefile
 LOB storage parameter that allows deduplication, encryption,
and compression
 9. Automatic Database Diagnostic Monitor (ADDM)
 This lets Oracle Database diagnose its own performance and
determine how identified problems could be resolved. It runs
automatically after each AWR statistics capture, making the
performance diagnostic data readily available.

 10. Automatic Workload Repository (AWR)
 A built-in repository in every Oracle Database. At regular interval
s, the Oracle Database makes a snapshot of all its vital statistics
and workload information and stores them here.
