Oracle database is one of the most popular commercial databases in the world. It plays an important role in enterprise application systems and Internet application systems. After installing the Oracle database, relevant configurations are required to adapt to various scenarios and applications. This article will introduce some general configuration after Oracle database installation.

1. Startup management of Oracle database service
When we install the Oracle database, Oracle's various services have been registered in the system. These services can be viewed, configured and started through the Service Manager. In Windows systems, we can open the "Service Manager" through "Services" in the "Start" menu. In Linux systems, we can operate the status of the systemctl service through the command line.

2. Database instance management
Oracle database instance refers to a specific running instance of the Oracle database. An Oracle installation can contain multiple instances, and each instance is an independent environment. In the Oracle database, instances can be created and managed through SQL statements or tools such as Oracle Enterprise Manager.

3. Database parameter configuration
There are many operating parameters for Oracle database. You can modify these parameters to optimize the operation of the database or adapt to specific application scenarios. In Oracle, we can use the command ALTER SYSTEM to modify database parameters. Modifications can also be made through the interface in Oracle Enterprise Manager.

4. User and permission management
In the Oracle database, a user refers to an account that can access database resources. Oracle database supports multiple user types, such as ordinary users, DBA, SYS, etc. In Oracle, user creation, modification and deletion can be achieved through SQL statement operations. In actual production environments, we usually need to use third-party software to visually manage users and permissions.

5. Backup and recovery management
In any database, data security is crucial. In order to ensure the data security of the database, we need to perform backup and recovery management. Oracle database provides a variety of data backup and recovery tools, such as RMAN, Data Pump, etc., which can perform backup and recovery operations according to actual needs.

6. Log and monitoring management
Through log and monitoring management, we can understand the running status of the Oracle database in real time, including the usage of resources such as CPU, memory, IO, etc., as well as the number of currently connected sessions, IO and other information. Oracle database provides a large number of monitoring tools, such as AWR reports, ASH reports, etc., for our use. At the same time, third-party tools can also be used to monitor the infrastructure and resource bottlenecks of the Oracle database and quickly troubleshoot when abnormalities or problems occur.

The above is the conventional configuration after Oracle database installation, which also includes performance optimization, security protection, etc., which requires more in-depth practice based on actual business scenarios. I hope this article can provide some help to everyone in the use and management of Oracle database.
