Type the following command and press Enter.

passwd oracle

Then type oracle at the New password prompt and press Enter (you’ll get the above warnings). Type oracle at the Retype new password prompt and press Enter.

Note:

See the note on Joes in the introduction. Your oracle user password should never be oracle if you care about the security of your system.

Type the following commands, pressing Enter after each line.

rpm -ivh http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux
yum install flash-plugin nspluginwrapper.x86_64 nspluginwrapper.i686 alsa-plugins-pulseaudio.i686 libcurl.i686

Note:

I shrank the terminal window so the commands would fit on one line, but this isn’t necessary. You can just continue typing past the end of the line and the command will wrap around to the next line. Don’t press enter until you’ve typed in the entire command. Also, check the output of the command as it’s not unusual to type one of the package names incorrectly. If you do, you can use the up arrow key and fix the command. It’s OK to try to install multiple times.

Type y at the Is this ok [y/N]: prompt and press Enter.

Type the following command and press Enter.

yum update

Note:

By default your Linux installation points to the public yum repository so there is no longer any need to update your yum configuration to get the above command to work. If you have support then you should first change your yum configuration to point to the correct repository.
Also, the package update process might have a hold on some files. If you get a message about this, just wait and eventually the hold will be released.

Type y at the Is this ok [y/N]: prompt and press Enter.

Note:

The number of packages may be different when you do your install if there have been more updates since this guide was written. You shouldn’t worry about it.

Type y at the Is this ok [y/N]: prompt and press Enter.

Type the following command and press Enter.

passwd

Type root at the New password prompt and press Enter (you’ll get the above error messages). Type root at the Retype new password prompt and press Enter.

Note:
See the note about Joes in the Introduction. Never use root as the root password for a system where security matters.

Oracle Database 12c on Oracle Linux 6 – Step 5: Disable the Firewall, iptables and SELINUX < Previous Post – Next Post > Oracle Database 12c on Oracle Linux 6 – Step 7: Update Oracle Linux with the Latest Software

Part of this series of posts: Oracle 12c on Oracle Linux 6

Click Other….

Enter root as the username and click Log In.

Enter rootroot as the password (or the password you used earlier) and click Log In.

Check Do not show me this again and click Close.

Note:

Or don’t check Do not show me this again if you want to see this warning each time you log in to the X-Windows GUI as root. In general you shouldn’t be logging into the GUI as root. We’re going to do so because it will be easier to use some of the system tools (no pop-ups to log in again as root) to configure our system.

Select System -> Administration -> Firewall from the menu bar.

Click Close.

Click Disable.

Click Apply.

Click Yes.

Select File -> Quit to close the Firewall Configuration.

Select System -> Administration -> Services from the menu bar.

Select the ip6tables service and click Disable.

Select the iptables service and click Disable.

Select Program -> Quit to close the Services Configuration.

Right-click the desktop and select Open in Terminal to open a terminal window.

Type the following command and press Enter.

gedit /etc/sysconfig/selinux

Note:

You can use Ctrl-Shift + (the plus key) to change the font size of your terminal windows. I also resize my windows to fill the whole screen. Between major command groupings I’ll also type clear to remove the previous commands from the window and start fresh.

Change SELINUX=enforcing to SELINUX=disabled.

Note:

Why disable SELINUX? According to user 546612 on the Oracle.com forums:

Depending on what pieces of Oracle you are using, there are setuid/setgid issues, there are network interactions, there is fork/exec permission stuff, shared memory, etc. Some stuff in Oracle runs as root, especially if you do RAC. There is a whole whack of IPC.

Note that Redhat recently published a paper that describes how to make SELINUX work with Oracle 11g R2 on Redhat which should work on Oracle Linux too. Since this is a test system, disabling was easier…
http://www.redhat.com/resourcelibrary/reference-architectures/deploying-oracle-11gr2-on-rhel-6

Make sure your SELINUX line reads SELINUX=disabled and Click Save.

Select File -> Quit from the menu to close gedit.
