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

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 client-side 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

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.

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

intervals, the Oracle Database makes a snapshot of all its vital statistics and workload information and stores them here.
