Download Software

Download the Oracle software from OTN or MOS depending on your support status.
2

Unpack Files

Unzip the files. You should now have a single directory called "database" containing installation files.

Code/Command (click line numbers to comment):

unzip linuxamd64_12102_database_1of2.zip
unzip linuxamd64_12102_database_2of2.zip
3

Hosts File

The "/etc/hosts" file must contain a fully qualified name for the server. For example. Set the correct hostname in the "/etc/hostname" file.

Oracle Installation Prerequisites

Perform either the Automatic Setup or the Manual Setup to complete the basic prerequisites. The Additional Setup is required for all installations.
5

Automatic Setup

If you plan to use the "oracle-rdbms-server-12cR1-preinstall" package to perform all your prerequisite setup, issue the following command. Earlier versions of Oracle Linux required manual setup of the Yum repository by following the instructions at http://public-yum.oracle.com . It is probably worth doing a full update as well, but this is not strictly speaking necessary. It's worth running the all the YUM commands listed in the manual setup section. Depending on the OS package groups you have selected, some additional packages might also be needed.

Code/Command (click line numbers to comment):

# yum install oracle-rdbms-server-12cR1-preinstall -y

# yum update -y
6

Manual Setup

If you have not used the "oracle-rdbms-server-12cR1-preinstall" package to perform all prerequisites, you will need to manually perform the following setup tasks. Add the following lines to the "/etc/sysctl.conf" file, or in a file called "/etc/sysctl.d/98-oracle.conf". Run one of the following commands to change the current kernel parameters, depending on which file you edited. Add the following lines to a file called "/etc/security/limits.d/oracle-rdbms-server-12cR1-preinstall.conf" file. Create the new groups and users. Uncomment the extra groups you require.

Additional Setup

The following steps must be performed, whether you did the manual or automatic setup. Set the password for the "oracle" user. Set secure Linux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows. Once the change is complete, restart the server or run the following command. If you have the Linux firewall enabled, you will need to disable or configure it, as shown here . To disable it, do the following. Create the directories in which the Oracle software will be installed. Putting mount points directly under root without mounting separate disks to them is typically a bad idea. It's done here for simplicity, but for a real installation "/" storage should be reserved for the OS. Unless you are working from the console, or using SSH tunnelling, login as root and issue the following command. Add the following lines at the end of the "/home/oracle/.bash_profile" file.

Installation

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable. Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory. Proceed with the installation of your choice. If you are doing an installation for an Enterprise Manager repository, remember to do an advanced installation and pick the ALT32UTF8 character set. Check out the notes below for how to deal with potential errors that may arise during the installation. You can see the type of installation I performed by clicking on the links below to see screen shots of each stage. - Configure Security Updates - My Oracle Support Credentials - Select Installation Type - System Class - Grid Installation Options - Select Install Type - Typical Install Configuration - Create Inventory - Perform Prerequisite Checks - Summary - Install Product - Execute Configuration Scripts - Oracle Database Configuration - Database Configuration Assistant - Database Configuration Assistant Complete - Finish - Database Express 12c Login - Database Express 12c Dashboard The "Database Configuration Assistant Complete" screen displays the Database Express 12c URL, which will be something like "https://ol7.localdomain:5500/em".

12.1.0.1 Notes

Only follow these notes if you are attempting the install using 12.1.0.1, there are a number of things that will need to be fixed along the way. These are not necessary for a 12.1.0.2 installation, as it completes cleanly. The following steps need to be considered during the installation. - When clicking "Next" on the "Download Software Updates" screen you will get the following message. Click the "Yes" button. When clicking "Next" on the "Download Software Updates" screen you will get the following message. Click the "Yes" button. - During the linking phase, you will see the following error. To fix it, do the following: Perform the following modifications to the "$ORACLE_HOME/rdbms/lib/env_rdbms.mk" file. Click the "Retry" button. During the linking phase, you will see the following error. To fix it, do the following: Perform the following modifications to the "$ORACLE_HOME/rdbms/lib/env_rdbms.mk" file. Click the "Retry" button. - Later, you might see the following error. To fix it, do the following: Perform the following modifications to the "$ORACLE_HOME/ctx/lib/env_ctx.mk" file. Click the "Retry" button. Later, you might see the following error. To fix it, do the following: Perform the following modifications to the "$ORACLE_HOME/ctx/lib/env_ctx.mk" file. Click the "Retry" button. Due to the issues during the linking phase, it probably makes sense to do a relink once the installation is complete.

12.1.0.2 Notes

During the linking phase, you may see the following error. To fix it, run the following command as the "oracle" user, then click the "Retry" button. During the database creation as part of the installation, or after when using the DBCA, you may get the following error. To fix it, follow the instructions to rebuild Perl as described towards the end of this post by Laurent Leturgez . You will have to redo the database creation. For more information see: Hope this helps. Regards Tim...
