How to install oracle11g silently

Oracle is the world's leading database management system, and its 11g version is favored by many enterprises and individual users. However, the installation process of Oracle11g is relatively cumbersome. If it needs to be installed on multiple machines, it will consume a lot of time and human resources. In order to improve installation efficiency, Oracle provides a silent installation method, which can complete the automatic installation of software without human intervention. This article will introduce how to silently install Oracle11g.

1. Preparation
Before silently installing Oracle11g, you need to prepare the following work:
1.Oracle11g installation media, usually a CD or ISO image;
2.Oracle11g The response file (.rsp file) of the installation file can be modified using the template file provided by Oracle;
3. Installation schedule (.lst file), used to record the installation process and error information;
4. Management A command line interface or terminal with administrator privileges, and sufficient disk space and memory resources.

2. Create a response file
The response file (.rsp file) is the key to the silent installation of Oracle11g. It records various parameter information that needs to be entered during the installation process. Oracle provides template files (such as db_install.rsp) for modification. If you need to customize the installation parameters, you can modify the file content according to the actual situation. The following is an example of a typical response file:

The response file for installing Oracle Database 11gR2

ASM_DISK_STRING="ORCL:*"

The above is part of the response file example, which contains Commonly used installation parameter settings are provided and can be modified according to actual conditions.

3. Create an installation plan
The installation plan (.lst file) is used to record the log information and error information generated during the silent installation of Oracle11g. Creating an installation schedule can facilitate troubleshooting problems during the installation process. Typically, the installation schedule can be configured in a response file as follows:

[GENERIC]

The name and file location of the installer log file.

If you do not specify a log file name or directory, the log

file is created in the /tmp directory. By default, the log

file name is "installActions.log".

Example:

LOGFILE=/u01/app/oracle/installer/log/installation.log

LOG_FILE="oraInstall.log"

The name and location for storing the inventory of installed software.

If you do not specify an inventory location, the software is

installed in the default inventory directory.

Example:

INVENTORY_LOCATION=/tmp/oracleInventory

INVENTORY_LOCATION="/u01/app/oraInventory"

Specify the name and file location for the installation plan file.

The installation plan file provides a record of all the configuration

settings you selected during installation.

Example:

INSTALL_PLAN=/u01/app/oracle/installer/log/ planFile.lst

INSTALL_PLAN="ora_install_plan.lst"

Specify the path to the remote shell program, if any.

This setting is required only if you are installing Oracle software

on a remote computer.

Example:

SSH_PATH=/usr/local/bin/ssh

SSH_PATH="/usr/bin/ ssh"

The above example is a configuration file for creating an installation schedule.

4. Perform silent installation
To perform silent installation, you need to use the command line interface or terminal, run with administrator privileges, enter the path where the Oracle11g installation media is located, and execute the following command:

. /runInstaller -silent -responseFile /path/to/response/file -ignoreSysPrereqs -ignorePrereq

Among them, the -responseFile parameter specifies the path and file name of the response file, the -silent parameter indicates running in silent mode, -ignoreSysPrereqs and The -ignorePrereq parameter indicates that system prerequisites and prerequisite checks are ignored.

During the installation process, you can modify the parameters according to the actual situation and follow the prompts until the installation is completed. After the installation is completed, log information and error information will be generated in the installation schedule, which can be used to troubleshoot problems.

Summary
This article introduces the steps of silent installation of Oracle11g, including creating a response file, creating an installation schedule and performing silent installation. Silent installation can significantly improve installation efficiency, especially when Oracle11g needs to be installed on multiple machines, it is more convenient and faster. I hope this article can help users who are installing Oracle11g and reduce their workload.
