Install Database
In fact Oracle installation
1 , ready to install
Oracle after the installation package download are two archive, select both right-click to decompress compressed package
2 , extraction is completed as shown below
3 , double-click the setup.exe file to install, the following window will pop up
Security Configuration: then will enter the installation interface, then let us fill in the e-mail, the mailbox is not a required option can be filled from time to fill in, do not fill, then there will be a prompt, we can direct disregard of, the next step is to click
Installation options: Direct Select the default to create and configure a database ( After installing database management software, the system will automatically create a database instance ) .
Installation Type: We choose the default desktop class
Typical installation: an important step. Only need to recommend Oracle base directory updates, the directory path do not contain Chinese or other special characters. Global database name can be the default, password and password must be kept in mind. When the password is entered, it prompted a warning, do not meet the Oracel not control when advice.
Such as the password is too simple, the system will prompt does not meet the oracle standards, we can click on a
Summary: When fill in information such as passwords, the system displays all the configuration information, such as we need to modify the configuration click the back can be re-fill, if there is no problem, we just click Finish.
Product installation: Because Oracle database is relatively large, the installation phase will take some time, we do not do anything directly wait for the system installation is complete.
File and database management software dbms files after installation, the installation automatically creates an instance of the default database front orcl the name of the database
After the instance of the database is created, the system will pop up a database of information, directly click OK, we can see that Oracle has been successfully installed. Then click the lower right corner to close the window is closed
Creating oracle database
Previously developed when used more than is mysql and sql server, oracle with a relatively small, relatively unfamiliar with them, mysql and sql server using up more similar to the oracle and use them in different ways, in the creation of a database of oracle to correspond to a user, database, and users generally correspond, mysql sql server and direct "database name" you can create a database by create databse direct, and create a oracle database requires the following three steps:
Create two table spaces (the so-called database) files
Create a user mapping form a relationship with the file created above
Add permissions to users
First, open the SQLPlus
Connections: Input: scott / tiger Enter
View users: show user
Switch to the system administrator
Input: conn as sysdba
Input: sysdba Enter
Enter the password directly
Show users: show user
Now is the administrator mode, you can create a table space (ie database)
First, create two database files (xxxx.dbf and xxxx_temp.dbf two files)
This book author orcacle mounted on the disk as follows: D: \ Softs \ Oracle \ product \ 11.2.0 \ dbhome_1 \ oradata \ xxxx.dbf
SQL> create tablespace xxxx logging datafile 'D:\Softs\Oracle\product\11.2.0\dbh
ome_1\oradata\xxxx.dbf' size 100m autoextend on next 100m maxsize 500m extent management local;
Second, create a user with the file created above to form a mapping relationship (user name xxxx, password xxxx)
CREATE USER xxxx IDENTIFIED BY xxxx DEFAULT TABLESPACE xxxx (TEMPORARY TABLESPACE xxxx_temp, the sentence may be omitted);
Third, add permissions
grant connect,resource,dba to xxxx;
grant create session to xxxx (can be omitted);
Sometimes used to delete the database and delete the user's operation, delete the statements given here
Fourth, delete the database
DROP TABLESPACE xxxx INCLUDING CONTENTS AND DATAFILES;
Fifth, delete users
drop user mxxxx cascade;
The above-described specific operations as follows:
