Oracle database is a very popular relational database management system, mostly used in large enterprise-level systems. When using Oracle database, startup and shutdown are one of the most basic operations, so it is very important to master the startup and shutdown operations of Oracle.
1. Oracle startup operation
1. Start the Oracle instance
For manually installed Oracle database systems, there are many ways to start the Oracle instance. The most common way is to use the sqlplus command line tool to start the operation. The steps are as follows:
Step 1: Open the command prompt, enter the expression "sqlplus / as sysdba", and then press the Enter key.
Step 2: Enter the Oracle system administrator account and password you set, and then press Enter to enter the Oracle internal management interface.
Step 3: Enter the expression "startup" and press Enter to start the Oracle instance.
2. Start the Oracle service
In some Windows systems, the Oracle service is set to start at startup by default. If the setting is unsuccessful, you can manually start the Oracle service through the following steps:
Step 1: Open the "Computer Management" console, select "Services and Applications" - "Services".
Step 2: Find Oracle-related services, such as OracleServiceORCL or OracleJobSchedulerORCL, etc., double-click to enter the properties interface.
Step 3: In the properties interface, set the service status to "Running" and set the startup type to "Automatic" or "Manual".
3. Start the Oracle listener
The Oracle listener is the network service of the database and is responsible for receiving requests from external sources and forwarding them to the database. There are many ways to start the Oracle listener. The most commonly used method is that users can directly perform the following operations on the command line interface:
Step 1: Open the command prompt, enter the expression "lsnrctl start", and press the Enter key.
Step 2: Wait for a period of time until keyword prompts such as "Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL...") appear, indicating that the Oracle listener is started successfully.
2. Oracle shutdown operation
1. Close the Oracle instance
When stopping the Oracle instance, use the sqlplus command line tool to perform the following operations:
Step 1: Open the command prompt and enter the expression Type "sqlplus / as sysdba" and press the Enter key.
Step 2: Enter the Oracle system administrator account and password you set, and then press the Enter key to enter the Oracle internal management interface.
Step 3: Enter the expression "shutdown", then enter "immediate" or "normal" to shut down, and finally press the Enter key to stop the Oracle instance.
2. Shut down the Oracle service
When closing the Oracle service, you can use the following methods:
Step 1: Open the "Computer Management" console, select "Services and Applications" - "Services".
Step 2: Find the Oracle-related service and double-click to enter the properties interface.
Step 3: In the properties interface, set the service status to "Stop" and set the startup type to "Manual" or "Disabled" ”.
3. Close the Oracle listener
When stopping the Oracle listener, you can use the following operations:
Step 1: Open the command prompt and enter the expression “lsnrctl stop" and press Enter.
Step 2: Wait for a period of time until keyword prompts such as "Listener Stop..." appear, indicating that the Oracle listener has been stopped.
Summary : The above are the detailed steps for starting and shutting down Oracle. I hope it will be helpful to everyone. Mastering these basic operating skills can make us more proficient in operating Oracle databases. Of course, different versions of Oracle database systems may be different. , so we need to make appropriate adjustments and debugging according to our actual situation.
The above is the detailed content of How to start and shut down oracle. For more information, please follow other related articles on the PHP Chinese website!

Oracle's product ecosystem includes databases, middleware and cloud services. 1. OracleDatabase is its core product, supporting efficient data storage and management. 2. Middleware such as OracleWebLogicServer connects to different systems. 3. OracleCloud provides a complete set of cloud computing solutions.

MySQL and Oracle each have advantages in performance, scalability, and security. 1) Performance: MySQL is suitable for read operations and high concurrency, and Oracle is good at complex queries and big data processing. 2) Scalability: MySQL extends through master-slave replication and sharding, and Oracle uses RAC to provide high availability and load balancing. 3) Security: MySQL provides fine-grained permission control, while Oracle has more comprehensive security functions and automation tools.

Oracle is called the "Powerhouse" of database management because of its high performance, reliability and security. 1. Oracle is a relational database management system that supports multiple operating systems. 2. It provides a powerful data management platform with scalability, security and high availability. 3. Oracle's working principles include data storage, query processing and transaction management, and supports performance optimization technologies such as indexing, partitioning and caching. 4. Examples of usage include creating tables, inserting data, and writing stored procedures. 5. Performance optimization strategies include index optimization, partition table, cache management and query optimization.

The development history of Oracle software from database to cloud computing includes: 1. Originated in 1977, it initially focused on relational database management system (RDBMS), and quickly became the first choice for enterprise-level applications; 2. Expand to middleware, development tools and ERP systems to form a complete set of enterprise solutions; 3. Oracle database supports SQL, providing high performance and scalability, suitable for small to large enterprise systems; 4. The rise of cloud computing services further expands Oracle's product line to meet all aspects of enterprise IT needs.

MySQL and Oracle selection should be based on cost, performance, complexity and functional requirements: 1. MySQL is suitable for projects with limited budgets, is simple to install, and is suitable for small to medium-sized applications. 2. Oracle is suitable for large enterprises and performs excellently in handling large-scale data and high concurrent requests, but is costly and complex in configuration.

Oracle helps businesses achieve digital transformation and data management through its products and services. 1) Oracle provides a comprehensive product portfolio, including database management systems, ERP and CRM systems, helping enterprises automate and optimize business processes. 2) Oracle's ERP systems such as E-BusinessSuite and FusionApplications realize end-to-end business process automation, improve efficiency and reduce costs, but have high implementation and maintenance costs. 3) OracleDatabase provides high concurrency and high availability data processing, but has high licensing costs. 4) Performance optimization and best practices include the rational use of indexing and partitioning technology, regular database maintenance and compliance with coding specifications.

Steps to delete the failed database after Oracle failed to build a library: Use sys username to connect to the target instance. Use DROP DATABASE to delete the database. Query v$database to confirm that the database has been deleted.
