Both registration and initial patching are done using the Update Agent (up2date) which was used in RHEL 4 and was abandoned by Red Hat in version 5. Registration requires ULN subscription.
Set proxy in /etc/sysconfig/rhn/up2date
Make access to oracle.com passwordless in your proxy configuration.

To use GUI version:
export DISPLAY=10.194.154.73:0 On Oracle 4&5
up2date --register &
On Oracle Linux 6 systems:
Follow the instructions on the screen and provide the requested information. up2date will also collect machine information and upload it to our server. Oracles New Linux - Oracle Linux up2date registration contains 17 slides that help to understand registration process
Up2date can be used in command line mode or via a GUI interface, and it can also monitor your system and do downloads and installs packages on its own using it but for the latter purpose yum is a better tool. Please note that Oracle VM only supports the command line text mode. Examples of the most frequently used command line operations are listed later in this document.
Up2date provides an applet for the toolbar, called the Alert Notification Tool, which periodically checks for updated packages and indicates whether there are new RPMs available for download.
In order to use ULN and up2date, users must register their systems with ULN and subscribe to a ULN channel (it is also possible to subscribe to multiple channels at once, see below for details). There are several ULN channels available and one containing the latest version is automatically chosen upon registration depending on the architecture and OS revision of the system to be managed (see below for a detailed description of the ULN channels).
Once started, the up2date program connects to the central ULN server repository and downloads the latest software packaged in RPM format. It then installs such RPMs on the registered machine, maintaining a log. Up2date lets the user choose which packages to update, as it is not necessary that all the newly available packages are installed. Users can get a list of all the available packages and then choose which ones are downloaded. Up2date resolves RPM dependencies for you...
Here is relevant information from Unbreakable Linux Network FAQ (February 11, 2011)
How do I obtain a login for Unbreakable Linux Network (ULN)?
You may register for a ULN account via linux.oracle.com/register You will need the following:
How do I register a machine with Unbreakable Linux Network (ULN)?
- An Oracle.com Single Sign on account. If you don't have one already, the link above will guide you through the steps to create one
- A valid Oracle Linux support or Oracle VM support CSI (customer support identifier). You may purchase Oracle Linux or Oracle VM support via the Unbreakable Linux Store or via your sales representative.
If you are currently running Red Hat Enterprise Linux Server, follow these steps. If you are running Oracle Linux, use the following steps:
When I register, I see the following message, "This system profile has already been registered." What do I do? (Oracle Linux 4 and Oracle Linux 5 only)
- Ensure you have a valid CSI by purchasing a support license via the Unbreakable Linux Store.
- Ensure you have an account on ULN. You may register for a new account via linux.oracle.com/register
- Execute the following command as the root user and follow the directions on the screen
On Oracle Linux 4 or Oracle Linux 5 systems:
- # up2date --registerNote: To use the up2date program in text mode, use this command instead:# up2date --nox --register
On Oracle Linux 6 systems:
- # uln_register
Most likely this means that your server is already registered with ULN. If you'd like to re-register a machine, please log in to ULN via the web interface and delete the system via the Systems tab. If the system you are registering is not already registered, but is a clone of an another system, follow these steps:
When I attempt to register a system via up2date or uln_register using my Single Sign On (SSO) account, I see the following message, "You must enter a valid e-mail address." My SSO account is not an email address, what do I do?
- Run the uuidgen(1) command to re-generate the system UUID - specifying the -r option generates a random UUID, while the -t option generates a UUID based on the system's network card MAC (hardware) address. Record the output of the uuidgen command, e.g.# /usr/bin/uuidgen -r 1c460880-5a10-4d19-a115-5d5d409ace39 OR # /usr/bin/uuidgen -t e65006be-2b31-11dd-8799-00163e39e605
- Using a text editor, open the /etc/sysconfig/rhn/up2date-uuid file and replace the existing value of the rhnuuid parameter with the output of the uuidgen command# cat /etc/sysconfig/rhn/up2date-uuid uuid[comment]=Universally Unique ID for this server #rhnuuid=91d0junk-1538-11db-8f59-123bdba2bb0f rhnuuid=1c460880-5a10-4d19-a115-5d5d409ace39
- Save the changes to the /etc/sysconfig/rhn/up2date-uuid file, then register the system again using the up2date utility - registration should then succeed.
To update your SSO account to a valid email address ready for use with up2date or uln_register:
You may now use up2date or uln_register with your changed SSO username.
- follow these instructions
- Log in to ULN using a web browser
How do I know whether my machine is registered?
To confirm whether your machine is registered, you can use the following command:
On Oracle Linux 3, 4 or 5 systems:I only see one channel after I have registered my system, how can I subscribe to additional channels?
On Oracle Linux 6 systems:
- # up2date --show-channels
You should see output similar to the following:el4_i386_latest
- # yum repolist
You should see output similar to the following:repo id repo name status ol6_x86_64_latest Oracle Linux 6 Latest (x86_64) 8,029
When you register a server, it will be subscribed to a channel that has the latest Oracle Linux packages for the appropriate architecture. To subscribe to additional channels, log in to linux.oracle.com after you register your system. Click on the Systems tab to manage subscriptions for each subscribed server.When I attempt to update my system, I get unresolved package errors, what can I do about this?
This could be caused by any number of issues in the communication between your machine and the ULN servers. One of the main causes could be some stale headers in your machine's up2date cache. This can be accomplished with the following command:
The Alert Notification Tool says that updates are available, but when I click on it to launch up2date, nothing happens, what's wrong? (Oracle Linux 4 and Oracle Linux 5 only)
- For Oracle Linux 3, 4 or 5 systems:# rm /var/spool/up2date/*
- For Oracle Linux 6 systems:# yum clean all
If you have installed Oracle Linux from installation media downloaded from Oracle or installed an earlier version of the Oracle Linux up2date rpm, then the graphical user interface (GUI) version of up2date may not be available. Clicking on the Alert Notification Tool icon at the top of the screen will do nothing until the GUI up2date agent is installed. If you've already registered your server (if not, see the answer to question 2), simply run the following as root to install the latest version of the up2date GUI first:# up2date-nox -uI encounter an SSL error when I try to use up2date. This was working before, what's wrong? (Oracle Linux 4 and Oracle Linux 5 only)
If you encounter the error below, please read this announcementThere was an SSL error: [('SSL routines', 'SSL3_GET_SERVER_CERTIFICATE', 'certificate verify failed')] A common cause of this error is the system time being incorrect. Verify that the time on this system is correct.How do I configure up2date/yum to use a proxy server?
Oracle Linux 6
If you're using a graphical desktop environment:
At the time of registering the system to ULN using uln_register , press the Advanced Network Configuration button after prviding the account information on Account Information screen. In the next window, use the appropriate fields for your HTTP proxy; if your proxy requires authentication, enter the username and password here. When finished, press the Close button to continue the registration process.If you're in text mode:
At the time of registering the system to ULN using uln_register, use --proxy option specify http proxy to use
# uln_register --proxy=proxy_hostname:port_number
if your proxy requires authentication use additional options --proxyUser and --proxyPassword to specify username and password
# uln_register --proxy=proxy_hostname:port_number --proxyUser=username --proxyPassword=password
Oracle Linux 4 and Oracle Linux 5
If you're using a graphical desktop environment:
If you're in text mode:
- From a terminal, as root, run up2date-config to launch the ULN Configuration tool
- Check the box next to Enable HTTP Proxy
- In the adjacent field, type the name of your proxy server, including port, for example proxy.example.com:80
How do I upgrade my Oracle VM environment from v2.1.5 to v2.2?
- As root, run up2date-config --nox
- Use the numbered menu to change up2date settings as follows:
- Set enableProxy to Yes
- Set httpProxy to the name of your proxy server with port, e.g. proxy.example.com:80
- If your proxy server requires authentication, set proxyUser and proxyPassword also
If you are using Oracle VM Manager to manage your environment, you should upgrade the components of your environment in the following order:
To upgrade each Oracle VM 2.1.5 Server to Oracle VM Server 2.2 follow these steps:
- Upgrade the Oracle VM Manager software from v2.1.5 to v2.2 from the Oracle VM 2.2.0 Installation Media
- Upgrade all of the Oracle VM servers except the Master (see the procedure below).
- Finally, upgrade the Oracle VM server that is the Master server (see the procedure below).
- Install ovm22upgrade package# up2date ovm22upgrade
- Run python script as suggested by the rpm install process# /usr/local/sbin/ovm22upgrade.py
- Upgrade package using following command and reboot the system# up2date -fu
How can I get help?
You can get help in the following ways:
- If you have purchased Basic or Premier support, you may use My Oracle Support (formerly MetaLink) for technical assistance
- If you have purchased Network support, you may discuss technical issues on the OTN Oracle Linux forum or file bug reports using Bugzilla
- For any other questions, please send an email to email@example.com
How do I update a specific package?
After registering and subscribing to required channels, run the following up2date command:
On Oracle Linux 3, 4 or 5 systems:
- # up2date -u <package_name>On Oracle Linux 6 systems:
- # yum update <package_name>
Oracle Linux up2date registration
Unbreakable Linux SupportEnterprise Linux offers an option to keep your operating system upto date with latest operating system patches using up2date. To be able to use this option you need to have Unbreakable Linux Support. For more information please visit http://linux.oracle.com
Note: Prior to using up2date, import the RPM-GPG-KEY for Enterprise Linux: rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY
If updating a large number of rpms (e.g. > 1000), be sure to set the 'open files' limit to a higher value to avoid up2date failing with the following error (due to hitting the open files limit):python: ./rpmio_internal.h:525: c2f: Assertion `fd && fd->magic == 0x04463138' failed.
