Finding Important Errata and CVE Information on ULN

I have recently received several questions about how to find information relating to critical security updates or important errata releases for Oracle Linux. I realized that perhaps people were not aware of the new features and improvements to Unbreakable Linux Network (ULN), which assist users with common administrative tasks. I wanted to take a quick moment to highlight for you some of the changes we have made. First, there are two links you will want to bookmark:

Each link will allow the user to evaluate what updates have been made available for Oracle Linux.

With https://linux.oracle.com/errata you are able to view all errata releases available, listed by type, severity, advisory, summary and release date. In addition, you are also able to filter this list by release and/or type (Bug, Security, Enhancement) and if you select an item from the list you will receive additional details regarding the errata, including a description, related CVEs and the packages updated by the errata.  You can also navigate to this same information by logging into ULN and selecting the 'Errata' tab from the options across the top.

For those who need information on security errata involving CVE identifiers (Common Vulnerabilities and Exposures) we have created https://linux.oracle.com/cve. This site allows you to gather information on important CVE identifiers, by providing a summary of all CVE offered through ULN. This summary is listed by CVE identifier and includes a brief synopsis and the release date. You can also filter the list by year. In addition, when you select a specific CVE identifier, you will receive additional details, such as information on CVSS v2 metrics as well as affected platforms.

We have been working to bring more features to ULN and these updates should provide more tools to simplify your administrative activities. Happy patching!

Introducing the Ksplice Offline client

We are excited to announce the availability of a new feature in our Ksplice service, known as the Ksplice offline client.  This new option eliminates the requirement on a direct connection to the internet to apply zero-downtime Ksplice patches.  The Ksplice offline client allows the user to create a local YUM repository which will mirror the Ksplice channel from ULN (Unbreakable Linux Network).  Once you have mirrored the channel on your local network, you simply apply the patch using the same Ksplice tools and commands you are already familiar with.  Ksplice is available to all customers with Oracle Linux Premier or Oracle Linux Premier Limited support.  Take a look at Wim's blog, where he provides an excellent example for how to setup and use this new service and if you are using Red Hat and want to try Ksplice, you can sign up for a 30 Day Free trial

OS Analytics with Oracle Enterprise Manager (by Eran Steiner)

Oracle Enterprise Manager Ops Center provides a feature called "OS Analytics". This feature allows you to get a better understanding of how the Operating System is being utilized. You can research the historical usage as well as real time data. This post will show how you can benefit from OS Analytics and how it works behind the scenes.

The recording of our call to discuss this blog is available here:

https://oracleconferencing.webex.com/oracleconferencing/ldr.php?AT=pb&SP=MC&rID=71517797&rKey=4ec9d4a3508564b3

Download the presentation here

See also:

Blog about Alert Monitoring and Problem Notification

Blog about Using Operational Profiles to Install Packages and other content


Here is quick summary of what you can do with OS Analytics in Ops Center:

  • View historical charts and real time value of CPU, memory, network and disk utilization
  • Find the top CPU and Memory processes in real time or at a certain historical day
  • Determine proper monitoring thresholds based on historical data
  • Drill down into a process details

Where to start

To start with OS Analytics, choose the OS asset in the tree and click the Analytics tab.

You can see the CPU utilization, Memory utilization and Network utilization, along with the current real time top 5 processes in each category (click the image to see a larger version):


 In the above screen, you can click each of the top 5 processes to see a more detailed view of that process. Here is an example of one of the processes:


One of the cool things is that you can see the process tree for this process along with some port binding and open file descriptors.

Next, click the "Processes" tab to see real time information of all the processes on the machine:


An interesting column is the "Target" column. If you configured Ops Center to work with Enterprise Manager Cloud Control, then the two products will talk to each other and Ops Center will display the correlated target from Cloud Control in this table. If you are only using Ops Center - this column will remain empty.




The "Threshold" tab is particularly helpful - you can view historical trends of different monitored values and based on the graph - determine what the monitoring values should be:

You can ask Ops Center to suggest monitoring levels based on the historical values or you can set your own. The different colors in the graph represent the current set levels: Red for critical, Yellow for warning and Blue for Information, allowing you to quickly see how they're positioned against real data.

It's important to note that when looking at longer periods, Ops Center smooths out the data and uses averages. So when looking at values such as CPU Usage, try shorter time frames which are more detailed, such as one hour or one day.


Applying new monitoring values

When first applying new values to monitored attributes - a popup will come up asking if it's OK to get you out of the current Monitoring Policy. This is OK if you want to either have custom monitoring for a specific machine, or if you want to use this current machine as a "Gold image" and extract a Monitoring Policy from it. You can later apply the new Monitoring Policy to other machines and also set it as a default Monitoring Profile.

Once you're done with applying the different monitoring values, you can review and change them in the "Monitoring" tab. You can also click the "Extract a Monitoring Policy" in the actions pane on the right to save all the new values to a new Monitoring Policy, which can then be found under "Plan Management" -> "Monitoring Policies".


Visiting the past

Under the "History" tab you can "go back in time". This is very helpful when you know that a machine was busy a few hours ago (perhaps in the middle of the night?), but you were not around to take a look at it in real time. Here's a view into yesterday's data on one of the machines:


You can see an interesting CPU spike happening at around 3:30 am along with some memory use. In the bottom table you can see the top 5 CPU and Memory consumers at the requested time. Very quickly you can see that this spike is related to the Solaris 11 IPS repository synchronization process using the "pkgrecv" command.

The "time machine" doesn't stop here - you can also view historical data to determine which of the zones was the busiest at a given time:


Under the hood

The data collected is stored on each of the agents under /var/opt/sun/xvm/analytics/historical/

  • An "os.zip" file exists for the main OS. Inside you will find many small text files, named after the Epoch time stamp in which they were taken
  • If you have any zones, there will be a file called "guests.zip" containing the same small files for all the zones, as well as a folder with the name of the zone along with "os.zip" in it
  • If this is the Enterprise Controller or the Proxy Controller, you will have folders called "proxy" and "sat" in which you will find the "os.zip" for that controller

The actual script collecting the data can be viewed for debugging purposes as well:

  • On Linux, the location is: /opt/sun/xvmoc/private/os_analytics/collect

If you would like to redirect all the standard error into a file for debugging, touch the following file and the output will go into it:

# touch /tmp/.collect.stderr  

The temporary data is collected under /var/opt/sun/xvm/analytics/.collectdb until it is zipped.

If you would like to review the properties for the Analytics, you can view those per each agent in /opt/sun/n1gc/lib/XVM.properties. Find the section "Analytics configurable properties for OS and VSC" to view the Analytics specific values.

I hope you find this helpful! Please post questions in the comments below.

DTrace for Oracle Linux news: new beta release and conference appearances

A new set of RPM packages of our port of DTrace for Linux has just been published on the Unbreakable Linux Network. This is another beta release of our ongoing development effort to bring the DTrace framework to Linux.

This release includes the following changes:

  • The packages are now based on the final public release of the Unbreakable Enterprise Kernel Release 2 (2.6.39). The previous beta drop was based on a development version of the 2.6.39 kernel; there is no new functionality specific to DTrace in this release. The primary goal was to get the code base in sync with the released kernel version.
  • Based on the feedback we received from some users in how their applications interact with dtrace, libdtrace is now a shared library. However, the API/ABI is not fully stabilized yet and may be subject to change.
  • As a result of the ongoing QA testing, some test cases were reorganized into their own subdirectories, which allows running the test suite in a more fine-grained manner.

As reminder, we have a dedicated Forum for DTrace on Linux, to discuss your experiences with this release.

This week, the Linux DTrace team also attendeded the second dtrace.conf in San Francisco, to talk about their work. The sessions were streamed live and recordings are also available. You can watch Oracle's Kris Van Hees' talk below:


Video streaming by Ustream

We would like to thank the dtrace.conf organizers for the speaking opportunity and for organizing this event!

This Wednesday (April 4th), Kris and Elena Zannoni also spoke on this topic at the Linux Foundation Collaboration Summit 2012 in San Francisco, CA. The slides are now available for download (PDF).
