Oracle monitoring installation

Oracle database is the most widely used commercial database management system in the world at present. It adopts client/server architecture and has excellent performance in high-load and large-scale enterprise application systems, and is widely used in finance, telecommunications, medical care, electric power, government and other industries. During the installation of Oracle database, Listener is a key link, which is used to monitor the connection request of the client and forward it to the Oracle service process to ensure the normal operation of the database. This article will introduce you to the installation and configuration process of Oracle Monitor to help you successfully complete the installation of Oracle database.

First, install the Oracle database

Before introducing the monitoring installation, we need to complete the installation of Oracle database. The installation process of Oracle database needs to be carried out according to the official documents. Here, only some common problems and solutions are introduced.

Operating system version Oracle database supports multiple operating systems, and different versions of the database correspond to different operating system versions. Before installation, you need to carefully check the official documents to confirm whether the local operating system meets the requirements. Otherwise, the installation may fail or the installed database may not run normally.

Installation order The installation order of Oracle database is very important. Usually, you need to install the database software first, and then create a database instance. Among them, the installation of database software is relatively simple, just follow the official documents. However, the following points should be noted when creating a database instance:

(1) Confirm whether the character set of the local operating system supports the character set of the database instance;

(2) Confirm whether the parameters of the database instance are set correctly, such as memory allocation and storage path;

(3) Confirm whether the default user password of Oracle has been changed. If it has been changed, you need to enter the correct password when creating the database instance.

Second, the monitoring installation

After completing the installation of the database, the next step is the installation process of monitoring. Monitoring is an important part of Oracle database, which is responsible for monitoring the connection request of the client and forwarding it to the Oracle service process, and also managing the network communication with other Oracle instances. Oracle database supports many types of monitoring, including TCP/IP, Unix Domain Socket, etc. Below we will introduce the installation and configuration process of monitoring with TCP/IP as an example.

Monitoring installation has a Netca file under the Oracle database installation directory, which is the configuration tool for monitoring installation. After opening the file, follow the following steps:

(1) select configure net service name and listener and click Next；;

(2) Select Listener Configuration and click Next；;

(3) Select Add and click Next；;

(4) Enter the necessary information such as monitoring name, monitoring protocol type (TCP), monitoring address, monitoring port, etc., and specify a password for managing monitoring (the password must be different from the password of Oracle user name);

(5) Click Next and complete the subsequent settings until the Summary interface appears;

(6) Click Finish to complete the configuration of monitoring.

After the monitoring installation is completed, you need to configure the running parameters of the monitoring. The configuration file for Oracle listening is located under Oracle_Home/network/admin/ and the file name is listener.ora In this file, you can configure the parameters of Oracle listening, such as listening name, listening address, listening port, logging, etc. The following is a sample configuration file:

# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora# Generated by Oracle configuration tools.LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST =localhost)(PORT = 1521)) ) )ADR_BASE_LISTENER = /u01/app/oracle

In this file, LISTENER is the listening name, and (description = (address = (protocol = TCP) (host = localhost) (port = 1521)) is the listening address and port configuration. You can modify the parameters according to your needs. After saving the configuration file, you need to restart the Oracle database instance and the listening service to take effect. You can use the following command to view the status of monitoring:

$ lsnrctl status [listener_name]

At this point, if the Listener is running is prompted, the monitoring has been successfully run.

Third, summary

This paper introduces the installation and configuration process of Oracle database monitoring. The premise is to complete the installation of Oracle database, then install the monitor through Netca, and finally configure the running parameters of the monitor under Oracle_Home/network/admin/. In practical work, it is necessary to modify the monitoring parameters according to the specific needs to ensure the normal operation of the Oracle database.
