I'm using Windows 64-bit, Oracle 10: http://www.oracle.com/technetwork/cn/database/database10g/downloads/index.html

(Remember, there are two 11g installation files downloaded from the official website. They must be downloaded and put together before installation)

You need to register a user during the download process.

Oracle is divided into oracle8/8i, oralce 9I (I represents the network development), Oracle 10g (over-product, G has the meaning of grid, relatively fast ), oracle 11g (integrity product)

However, it is too slow to install the GB package. If an error occurs, it cannot be installed again.

Install

1. First shut down the firewall and shut down the network (if there are still errors in these two measures, it should be a good character)

2. Run the installer (you can right-click it and run it as an administrator)

Select Enterprise Edition (default)

General (default)

Database Configuration Options: The Global Database Name and mid are the same. It is important to check the database instance: "Create a database with a sample solution". If this option is not selected, there will be no large data users

You can use the default settings for other operations. do not perform any other operations after clicking "Install.

3. After the installation is complete, configure the database ----- go to the password management page

There are mainly four users/passwords:

1. Super administrator: SYS/charg_on_install

2. Common administrator: System/Manager

3. Common users: Scott/tiger -----> the instance is locked by default.

4. Big Data Users: sh/SH

Go to password management, remove the check boxes before several users, and modify the password:
Installation is complete. Exit is complete!
After completion, the following services will be enabled by default in the computer service, and they will all be disabled,
4. About Oracle uninstallation (it is best not to unload it. It may be impossible to load it after it is finished)
You are advised to run the uninstall command in the following ways:
* Directly run the uninstall program;
* Delete the residual files on the hard disk. If the files are not deleted, delete them in safe mode;
* Delete all related configurations in the registry;
5. Listener problems (important issues) are generally two common errors.
(One is to use
Master windows optimization, Super Rabbit, and so on, accidentally deleted the Registry file. One is manually modified the computer name.)
···ErrorI: What kind of Windows optimization masters and super rabbits are used?
At this time, the listener service will usually be turned on, refreshed, and shut down again
· Error 2: Network Environment Changes
The files to be modified are as follows:
The two files mainly modify the content of the file HOST: change the name of the host to the modified content; for example:
Add a database. Open the following content first.
Add a database as follows: (the Global Database Name and Sid must be consistent with the original database)
Save the file
This sentence will be added to the file later.
Complete.
