In today's digital age, businesses need more efficient data management and processing, which is why a database management system (DBMS) is so important. Oracle is one of the most used and reliable database management systems out there. However, just like any other software, you may encounter some problems and challenges when using it. One of the common problems is Oracle connection time. This article will explore how to set connection time in Oracle.
The connection time is a preset time period used to control how long a connection that has not been used is closed. In Oracle, this period of time is called "session idle timeout", which means that idle connections that exceed the set time will be automatically closed. This time period is set by the database administrator in the database configuration. Generally speaking, a connection time that is too short will cause users to lose connection, while a connection time that is too long will cause resource waste and security issues.
Next we will introduce 3 methods to set the connection time.
- Set the connection time using SQL statements
In Oracle, you can set the connection time by executing the following SQL statement:
SQL> ALTER SYSTEM SET IDLE_TIME = 60;
This will set the connection time in the database Set a timer for the connection to be idle for 60 minutes. This timer will start whenever a client connects to the database.
- Use Oracle Management Server (OMS) to manage connection time
Oracle Management Server (OMS) is a powerful tool for Oracle database management. It provides a management platform for configuring and monitoring Oracle databases. Connection times can be managed using OMS. The following are the steps to set the connection time:
a. Open the OMS interface and find the database instance.
b. Go to the "Resources" tab, find "Database Parameters" under "Management" and click on it.
c. Find the "Idle Time" option and modify it to the desired time.
d. Click the Apply button to save changes.
- Set the database parameter file
This method involves modifying the Oracle database configuration file. This is an advanced method and should only be used by experienced database administrators. Follow the steps below to set the connection time:
a. Find the parameter file (spfile or pfile) in the Oracle database installation directory.
b. Find the "SQLNET.INBOUND_CONNECT_TIMEOUT" and "SQLNET.EXPIRE_TIME" settings and change them as needed.
c. Save and restart the database for the changes to take effect.
Summary
In Oracle database, connection time is a very important element, which can ensure the efficient operation of the database. You can set the connection time for the database by using SQL statements, Oracle Management Server (OMS), or setting database parameter files. Regardless of which method is used, care should be taken and best practices should be followed to ensure the security and reliability of the database.

Oracle software applications in the real world include e-commerce platforms and manufacturing. 1) On e-commerce platforms, OracleDatabase is used to store and query user information. 2) In manufacturing, OracleE-BusinessSuite is used to optimize inventory and production planning.

The reason why Oracle software shines in multiple fields is its powerful application and customized solutions. 1) Oracle provides comprehensive solutions from database management to ERP, CRM, SCM, 2) its solutions can be customized according to industry characteristics such as finance, medical care, manufacturing, etc. 3) Successful cases include Citibank, Mayo Clinic and Toyota, 4) The advantages lie in comprehensiveness, customization and scalability, but challenges include complexity, cost and integration issues.

Choosing MySQL or Oracle depends on project requirements: 1. MySQL is suitable for small and medium-sized applications and Internet projects because of its open source, free and ease of use; 2. Oracle is suitable for core business systems of large enterprises because of its powerful, stable and advanced functions, but at a high cost.

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.
