How to install oracle rac 11g (tutorial)
Oracle RAC (Real Application Clusters) is a cluster solution provided by Oracle to achieve scalable and high availability. I believe many people have learned about Oracle RAC, but the installation process may be complicated. This article will take you to learn more about the installation process of Oracle RAC 11g.
Part 1 Preparation work
Before installing Oracle RAC 11g, you first need to complete some preparation work, as follows:
- Operating system configuration
In order to ensure the normal operation of Oracle RAC, we need to make some settings on the operating system. The specific content that needs to be set includes:
- Login user: First, you need to create two Linux accounts (e.g. oracle and grid). The oracle account will be used to install and run Oracle software, while the grid account will be used to install and run the Oracle software. Used to implement cluster control.
- Virtual IP address: The virtual IP address is an important part of Oracle RAC for load balancing, so it needs to be prepared in advance, usually through the Linux network configuration file.
- Disk partition: In order to achieve data sharing with Oracle RAC, a shared disk partition needs to be configured in the storage system and mounted on each node.
- Installing software packages
Before installing Oracle RAC 11g, you need to install some necessary software packages, as follows:
- rpm package: Oracle needs to rely on a large number of rpm packages for installation and use, so it needs to be installed in advance.
- gcc package: Oracle also needs to rely on the gcc development package, so it also needs to be installed in advance.
In addition, you need to install some additional software packages, including:
- Install CVU (Cluster Verification Utility): CVU is used to check whether the Oracle RAC cluster environment meets The required tools need to be installed in advance.
- Install SSH: SSH needs to be used for communication between nodes during the Oracle installation process, so SSH needs to be installed in advance.
Part 2 Install Oracle Grid Infrastructure
Oracle Grid Infrastructure is an important part of Oracle RAC, which includes Oracle Clusterware and Oracle ASM. The following are the installation steps of Oracle Grid Infrastructure:
- Extract the installation package
First you need to decompress the installation package of Oracle Grid Infrastructure to the specified directory, for example:
# mkdir /u01/app/oracle/product/grid # unzip linux.x64_11gR2_grid.zip -d /u01/app/oracle/product/grid
- Create accounts and groups
Before installing Oracle Grid Infrastructure, you need to add the oracle and grid accounts to the oinstall, dba and oper user groups. To facilitate permission control during the installation process.
# groupadd oinstall # groupadd dba # groupadd oper # useradd -g oinstall -G dba,oper oracle # useradd -g oinstall -G dba,oper grid
- Execute the installation file
Execute the grid/runInstall.sh file to enter the Oracle Grid Infrastructure installation wizard interface. The specific steps are as follows:
- Select the language
- Select the Grid Infrastructure installation type

- Check the running status of Oracle Grid Infrastructure: You can check it through the crsctl tool.
- Check whether the ASM instance is running normally: You can check it through the asmca tool.
Part 3 Install Oracle RDBMS
Oracle RDBMS is the core component of Oracle RAC. The following are the installation steps of Oracle RDBMS:
- Extract the installation package
First unzip the Oracle RDBMS installation package to the specified directory, such as:
# mkdir /u01/app/oracle/product/11.2.0/dbhome_1 # unzip p10404530_112030_Linux-x86-64_1of7.zip -d /u01/app/oracle/product/11.2.0/dbhome_1 # unzip p10404530_112030_Linux-x86-64_2of7.zip -d /u01/app/oracle/product/11.2.0/dbhome_1
- Create accounts and groups
While performing Oracle Before installing the RDBMS, you need to add the oracle and grid accounts to the oinstall, dba, and oper user groups to facilitate permission control during the installation process.
# groupadd oinstall # groupadd dba # groupadd oper # useradd -g oinstall -G dba,oper oracle # useradd -g oinstall -G dba,oper grid
- Execute the installation file
Execute the database/runInstaller file to enter the Oracle RDBMS installation wizard interface. The specific steps are as follows:
- Select the language
- Check the system settings
- Set the Oracle RDBMS installation directory and Oracle Base
- Select the installation type
- Check the installation startup conditions
- Start the installation
- Perform installation verification
After the installation of Oracle RDBMS is completed, you need to perform Installation verification. It can be verified through the following steps:
- Check the running status of Oracle RDBMS: It can be checked through the sqlplus tool.
- Check the running status of the RAC database: You can check it through the crsctl tool.
Part 4 Summary
The installation process of Oracle RAC 11g is relatively complicated, but as long as you follow the above steps, you can successfully complete the installation. During the installation process, you need to pay attention to some details, such as operating system settings, necessary software package installation, account and group creation, etc. These details have an important impact on the operating status of the Oracle RAC cluster, and therefore cannot be ignored.
In short, through the steps introduced in this article, you can easily complete the installation of Oracle RAC 11g and implement a scalable and highly available cluster solution.

How to solve the problem of closing oracle cursor
Apr 11, 2025 pm 10:18 PM
The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended. Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.

How to encrypt oracle view
Apr 11, 2025 pm 08:30 PM
Oracle View Encryption allows you to encrypt data in the view, thereby enhancing the security of sensitive information. The steps include: 1) creating the master encryption key (MEk); 2) creating an encrypted view, specifying the view and MEk to be encrypted; 3) authorizing users to access the encrypted view. How encrypted views work: When a user querys for an encrypted view, Oracle uses MEk to decrypt data, ensuring that only authorized users can access readable data.
