Enter the following command to set the current values of the kernel parameters in
/etc/sysctl.conf
:
[root@repositorydb ~]# /sbin/sysctl -p
Creating Required Directories
The Oracle base directory must have at least 5GB of free disk space. Enter commands to the following to create the
recommended subdirectories and set the appropriate owner, group, and permissions on them:
[root@repositorydb ~]# mkdir -p /u01/app/
[root@repositorydb ~]# chown -R oracle:oinstall /u01/app/
[root@repositorydb ~]# chmod -R 775 /u01/app/
Installing the Oracle Database Software
To install the database software, you need to download the installation files, unzip them, and then run the installer. All
the steps are laid out in this section.
You can download the Oracle database software from the Oracle Technology Network (OTN). The software is
available in zip files. Here's the link for Oracle Database:
We also recommend downloading and installing the latest patch set of Oracle Database software from My Oracle
Support.
After you download the installation files, copy them to a directory that the
ORACLE
user can access, and then
switch to the
ORACLE
user and unzip them:
[oracle@repositorydb ~]$ unzip linux_11gR2_database_1of2.zip
[oracle@repositorydb ~]$ unzip linux_11gR2_database_2of2.zip
After unzipping the files, you will see a newly created directory named
database
. Open this directory and run the
installer:
[oracle@repositorydb ~]$ cd database
[oracle@repositorydb ~]$ ./runInstaller
When the installer starts, complete the following steps:
1.
The first installer step is Configure Security Updates, shown in Figure
2-1
. You may prefer
not to enter My Oracle Support (MOS) credentials because you will be able to follow
all security updates by using Cloud Control. So deselect the I Wish to Receive Security
Updates option and click Next. The installer warns about the importance of receiving
critical security updates, but ignore the warning.
