An article introducing the basic knowledge of Oracle Linux
Oracle Linux is a Linux-based operating system, which is independently developed by Oracle. It is similar to RedHat Enterprise Linux (RHEL) and uses common kernel files and underlying services. In this article, we will introduce you to the basic knowledge of Oracle Linux, including installation, configuration and management.
Installing Oracle Linux
Before installing Oracle Linux, you need to obtain the Oracle Linux image file and related installation programs. Please obtain the corresponding software packages from Oracle's official website, including "oraclelinux-7.0-x86_64-dvd.iso" and "oraclelinux-7.0-x86_64-VirtualBox.box".
Generally, we can install Oracle Linux through the following two methods:
1. DVD-based installation method: use "oraclelinux-7.0-x86_64-dvd.iso" to create a Bootable DVD for installation.
2. Virtual machine-based installation method: First, create a new virtual machine in the virtual machine and use the Oracle Linux operating system file "oraclelinux-7.0-x86_64-VirtualBox.box" as a virtual hard disk. After that, we can start and install Oracle Linux through the virtual machine's console.
It should be noted that before installing Oracle Linux, we need to do some preparatory work, including hardware preparation and software environment preparation. For specific preparation work, please refer to the documents provided by Oracle's official website.
Configuring Oracle Linux
After installing Oracle Linux, we need to configure it to meet our actual needs. The following are some common configuration operations:
1. Set the host name of the system: You can set the host name of the system by modifying the "/etc/hostname" file, which makes it easier for us to manage and identify the system.
2. Configure the network: You can find the network configuration files in the "/etc/sysconfig/network-scripts/" directory and configure the system's network environment by modifying these files.
3. Install and configure SSH: SSH is a very common remote management method. Through SSH, we can access the system and manage it from anywhere. You can install the SSH service by running the "yum install sshd" command. After the installation is complete, you need to perform some configuration operations.
Manage Oracle Linux
After we complete the above operations, we can start to manage the Oracle Linux system. The following are some common management tips:
1. Use yum to install and manage software packages: Yum is a very powerful and convenient software package management tool, which can help us quickly install and manage various software Bag. For example, you can use the "yum install package-name" command to install a software package, and you can use the "yum remove package-name" command to uninstall a software package.
2. Use file system and disk management tools: You can use various file system and disk management tools to format, mount, unmount disks and other operations. Disk partitioning tools like diskpart can also help you perform more sophisticated disk management and repair or adjust disk partitioning and other issues.
3. Start and shut down services: You can use the systemctl command to manage the startup and shutdown of system services. For example, the "systemctl start service-name" command can start a service, the "systemctl halt service-name" command can shut down a service, etc.
Summary
In this article, we mainly introduce how to install, configure and manage the Oracle Linux operating system. Although this operating system is very similar to RHEL, it also has some special features and advantages. I hope this article can help you better understand and master the use of Oracle Linux, and improve your Linux system management capabilities.

In addition to SQL*Plus, there are tools for operating Oracle databases: SQL Developer: free tools, interface friendly, and support graphical operations and debugging. Toad: Business tools, feature-rich, excellent in database management and tuning. PL/SQL Developer: Powerful tools for PL/SQL development, code editing and debugging. Dbeaver: Free open source tool, supports multiple databases, and has a simple interface.

Solutions to Oracle cannot be opened include: 1. Start the database service; 2. Start the listener; 3. Check port conflicts; 4. Set environment variables correctly; 5. Make sure the firewall or antivirus software does not block the connection; 6. Check whether the server is closed; 7. Use RMAN to recover corrupt files; 8. Check whether the TNS service name is correct; 9. Check network connection; 10. Reinstall Oracle software.

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.

In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.

There are no shortcuts to learning Oracle databases. You need to understand database concepts, master SQL skills, and continuously improve through practice. First of all, we need to understand the storage and management mechanism of the database, master the basic concepts such as tables, rows, and columns, and constraints such as primary keys and foreign keys. Then, through practice, install the Oracle database, start practicing with simple SELECT statements, and gradually master various SQL statements and syntax. After that, you can learn advanced features such as PL/SQL, optimize SQL statements, and design an efficient database architecture to improve database efficiency and security.

To query the Oracle tablespace size, follow the following steps: Determine the tablespace name by running the query: SELECT tablespace_name FROM dba_tablespaces; Query the tablespace size by running the query: SELECT sum(bytes) AS total_size, sum(bytes_free) AS available_space, sum(bytes) - sum(bytes_free) AS used_space FROM dba_data_files WHERE tablespace_

Oracle sequences are used to generate unique sequences of numbers, usually used as primary keys or identifiers. Creating a sequence requires specifying the sequence name, starting value, incremental value, maximum value, minimum value, cache size, and loop flags. When using a sequence, use the NEXTVAL keyword to get the next value of the sequence.

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.
