Open Networking Reveals Its Fractal Nature
An insider's view of open networking.

Simply incredible. We spent last week at VMworld speaking with thousands of enterprise security, infrastructure and virtualization pros. It was humbling to witness all of the curiosity and excitement around Docker at the show, and how Docker clearly made a strong impression on the attendees.

This curiosity around Docker and its use within enterprise environments is the reason why i’m writing this blog. We noticed that there were many of the same questions that arose, and we figured we should share them with you, as you start your journey towards adopting Docker containers and VMs.
Here are the most commonly asked questions from the conference.
Containers are really about applications, not servers. That’s why they aren’t VMs. @docker #VMWorld #TFD

A Docker container is a standard unit in which application code, binaries and libraries can be packaged and isolated. The Docker Engine is the runtime installed on your infrastructure of choice and is what executes commands to build and deploy containers. Many containers can be connected together to form a Continue reading
Just went onto a customer’s Junos Space/Security Director installation to discover that their SRX5800 was showing as ‘out of sync’. I tried to do a ‘Resynchronize with Network’ from the Device Operations menu, but this failed with the following error:
Error while reading config from device: <devicename> javax.persistence. TransactionRequiredException: JBAS011469: Transaction is required to perform this operation (either use a transaction of extended persistence context)

JBAS011469 error in Space 15.2
Unfortunately (like most Space-related errors) there’s nothing about this in Juniper’s knowledgebase – the only hit I found on a Google search was a similar error, but with a different cause that had been fixed. So I thought I’d put this here in case it helps anyone.
The solution in the end was to update the DMI schema for the device. The SRX5800 had been upgraded from 12.1R3.5 to 12.3X48-D30.7 but the schema within Space had not. I downloaded the appropriate schema, and now the device re-syncs just fine.
While most readers, commenters, and Twitterati agreed with my take on the uselessness of OSPF areas and inter-area summarization in 21st century, a few of them pointed out that in practice, the theory and practice are not the same. Unfortunately, most of those counterexamples failed due to broken implementations or vendor “optimizations”.
