Download Software

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

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

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.

<IP-address>  <fully-qualified-machine-name>  <machine-name>

192.168.56.141  fedora25.localdomain  fedora25

fedora25.localdomain

Set Kernel Parameters

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. Set SELinux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows. The server will need a reboot for the change to take effect.

Setup

Before we consider the packages required by the Oracle installation, it's probably worth making sure some basic package groups are installed. If you have installed the suggested package groups, the majority of the necessary packages will already be installed. The following packages are listed as required, including the 32-bit version of some of the packages. Many of the packages should be installed already. Create the new groups and users. We are not going to use the extra groups, but include them if you do plan on using them. 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. If you are using X Emulation, login as root and issue the following command. Edit the "/etc/redhat-release" file replacing the current release information "Fedora release 25 (Twenty Five)" with the following. Login as the oracle user and 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. Ignore any warnings about the system configuration. 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://fedora25.localdomain:5500/em".

Installation Problems

If you are doing this installation in a VM on a Mac/PC with a new-ish chipset, you may encounter some issues, especially around the Perl installation. If so, check out these 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.

Post Installation

Edit the "/etc/redhat-release" file restoring the original release information. Edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'. For more information see: Hope this helps. Regards Tim...
