How to set the time for Oracle connection

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.

1. 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.

2. 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.

3. 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.
