First, Oracle downloadNote that Oracle is divided into two files, and after downloading, two files are extracted to the same directory. In the path name, it is best not to appear in Chinese, and do not appear spaces and other irregular characters.
Official Next Address: http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html The following two Web site source this official download page Web. Win 32-bit operating system: http://download.oracle.com/otn/nt/oracle11g/112010/win32_11gR2_database_1of2.ziphttp:// Download.oracle.com/otn/nt/oracle11g/112010/win32_11gr2_database_2of2.zipwin 64-bit operating system: http://download.oracle.com /otn/nt/oracle11g/112010/win64_11gr2_database_1of2.ziphttp://download.oracle.com/otn/nt/oracle11g/112010/win64 _11gr2_database_2of2.zip
Second, Oracle installation1. Unzip the file, select the two compressed package together, and click the right mouse button to unzip the file 2. Both unzip to the same path, 3. To the appropriate decompression path above, find the executable installation file "setup.exe" double-click the installation. 4. Install the first step: Configure the security update, this step can fill in the e-mail address (also can not fill in, just received some useless mail only). Cancel the "I want to accept security update (W) through my Oracle support" below. 5. Security options, directly select Create and configure a database by default (after the database management software is installed, a database instance is created automatically). 6. The system class, directly select the default desktop class is ready. (If the computer you are installing to is a personal notebook or personal computer Use this option) 7. Typical installation. Important step. It is recommended that you only update the Oracle base directory, and that the directory path does not contain Chinese or other special characters. The global database name can be defaulted, and password passwords must be kept in mind. Password input, there is a warning, do not comply with ORACEL recommendations without tube. (because the password rules recommended by Oracel are cumbersome, they must be uppercase and lowercase plus numbers, and must be more than 8 digits.) Trouble, you can enter the usual oneself habit of short password can) 8. If you enter a short, simple password, the installation will prompt the following. Just confirm Y to continue with the installation. 9. Prerequisite checks. The installer checks to see if the hardware and software system meets the minimum requirements for installing this Oracle version. The immediate next step is OK. 10. Outline some relevant selection configuration information prior to installation. You can save the file or do not save the file directly to the point of completion. 11. Install the product automatically, without tube. 12. After the database management software files and DBMS files are installed, a database that installs the ORCL name of the previous instance database is automatically created. 13. The instance database is created, the default is to lock all the accounts are unavailable (except SYS and the SYSTEM account is available), it is recommended to point to the right of password management, the common Scott account to unlock and enter the password. 14. Unlock the Scott account, remove the green tick from the front, and enter the password. You can also enter a short password that you normally use, and you don't have to add numbers to the 8-bit size that Oracle recommends. Oh. 15. Similarly, passwords that do not conform to the rules are prompted. Don't worry about it, continue Y. 16. The installation is successful and complete. It's simple, hehe.
third, after installation, enter the small testYou can start by using the "Oracle 11g", "Application Development", "SQL Developer or SQL Plus" connection in the application. Note For the first time, when you use SQL Developer, you are prompted to specify the path to Java.exe, so don't specify your own java_home here (I just don't know, specify a JDK6, end up saying incompatible.) You can use the Oracel installation path below the JDK path specifically:. Of course, if you are not careful, choose the wrong. Select the Java_home in the Advanced version, open SQL Developer error after the incompatibility, there are ways to solve. "Sqldeveloper.conf" can be found under "F:\app\chen\product\11.2.0\dbhome_1\sqldeveloper\sqldeveloper\bin" path After the file is opened, locate the value that Setjavahome matches, and delete the following configuration. The guarantee will prompt that the read-only file cannot be overwritten and saved. You can save it to the desktop, then go back to the bin directory to remove the file, and then copy the file on the desktop, and then open, re-select Java.exe. It's good to choose right now.
