CentOS-6.7 under Installation oracle11g

Detailed installation details can be found in the ORACLE11G official documentation (install.112/e24324/toc.html), where only a few major steps are recorded.

(1) Check the hardware

The missing package is installed with Yum, where the Pdksh package does not appear to be in the Yum source, it needs to be manually downloaded and installed

Edit the/etc/sysctl.conf file to append the following content to the end of the file

Then execute the sysctl-p command to make it effective

Next, edit the/etc/security/limits.conf file to append the following to the end of the file

(6) Install the graphical interface (not required)

Because the graphical interface is used to install Oracle, a graphical interface is required.

Execute the following command:

Yum groupinstall "X window System"

Yum Groupinstall Desktop

(7) Setting display environment variables

Can Baidu search "Linux DISPLAY variable Settings "

For setting the display environment variable, I did not succeed for a long time, simply gave up.

The simplest way is to start the graphical interface and then open a command-line window in the graphical interface, and all subsequent installation operations are

This window so that you do not have to set the display environment variable.

(8) The final preparatory work

Download the oracle11g installation file, merge the files from the two compressed packages into a single folder, and copy them to the virtual machine.

Another way to start and shut down a database is Dbstart and Dbshut

$oralce_home/dbstart and $oracle_home/dbshut in two footstep files, respectively.

Oracle_home_listner=$1 changed to oracle_home_listner= $ORACLE _home

at the same time, the/etc/oratab file orcl:/u01/app/oracle/product/11.2.0/dbhome_1:n

Change into Orcl:/u01/app/oracle/product/11.2.0/dbhome_1:y

At this point, running Dbstart and Dbshut will successfully start shutting down the database.
