PS: Novice, not installed database, all kinds of errors are basically encountered... history of blood and tears

1. Open the 11.2.0.3 installation script and check the log.

The reason for the error may be that dns does not return the IP of the service name, and it may be the host reason.

After checking that/etc/hosts is empty, you can roughly determine the cause of the error.

Add hosts (for example). Change IP and host name based on reality)

127.0.0.1 localhost.localdomain localhost

192.168.1.100 oracle

Open normally after saving changes

2, when installing, prompt the color problem, display environment variable through

Log out and use it, oracle user logs in again

3, Run./ runInstaller, oracle installer interface garbled

(1)export imported environment variables are temporary environment variables

#export LANG=en_US

(2)If it is not possible to temporarily change the character set of environment variables in Chinese environment, add Chinese font

#cp zysong.ttf /tmp

#mkdir -p /usr/share/fonts/zh_CN/TrueType

#cp zysong.ttf /usr/share/fonts/zh_CN/TrueType/

This is during installation. Oracle will display Chinese instead of Chinese garbled code.

4,Oracle installation process of various errors, such as 68% and 82% of the time pop up errors

Basically, it is caused by the lack of dependency packages. The environment check before installation should be paid attention to and the dependency packages should be supplemented.

5, After installation:sqlplus / as nolog, netca and dbca commands cannot be executed

Oracle environment variables are not configured well, check the installation path and environment variable settings

6. Database monitoring cannot be started after installation

IP setting error in hosts file, check and reset
