Iam new to Open Daylight and working on Network Application on Eclipse and using ODL to controll the network , but is there is any specified specs for the server that ODL will be deployed , i have read that ODL is deployed as an OVA image on server , but if my server is Ubuntu server do i have to use an ova image , or just intall the ODL on the server ?
ODL basic distribution (zip, tar.gz) installs on any machine running java 8. Default installation sets XmX=2G so I would say minimum specs would be 2xCPU + 4GB RAM but that will also depend on your application and how many features you require from ODL.

I have the following scenario:-
I am developing an SPA using Polymer for the client and a bespoke server using nodejs. It talks to an SQL Server Database on another computer entirely
The production version will run on a raspberry pi INSIDE a Docker container
I am trying to set up a CI system using jenkins on a desktop computer as the master, with a slave node as the raspberry pi. This system will operate in pairs - one pair will work at home (where the desktop is linux) and one pair will operate in an office (where the desktop is windows). A global git repository will allow me transfer between the two, and allow the jenkins machine and its slave to be driven by the same repository (exposed to the raspberry pi via ssh)
I am thinking it unlikely that I can install Docker on the desktop computer in the office
I would like to find a way to test the client aspect of this SPA against the content of the production Docker image. I can produce a test Docker image using the production image as a base in order to include additional test tools such as polymer-cli (which in turn includes web-component-tester and selenium). But that image would have to run on the raspberry pi where there isn't much choice of browser.
I currently run tests on my linux desktop with a nodejs javascript call like const child = spawn('xvfb-run', ['-a', 'wct', '--color'], {cwd: path.resolve(__dirname, 'client')});
What I can't quite get my head around is some portion of web testing is driven by nodejs talking to selenium which then fires up a browser, but where? and then nodejs is serving the content to the browser where it is run (and I am using xvfb-run to capture the output from the browser). Is it possible to have the browser run on another machine (either the windows desktop machine or the place where the global git repository is located)
I am trying to deploy a cent-os 7 VM on a vcenetr from pyvmomi python library and then before powering on the VM I am trying to setup static IP and DNS for the VM.
VM creation goes fine , but guest customization fails, givimg following error:
**Customization of the guest operating system 'rhel6_64Guest' is not sup
ported in this configuration. Microsoft Vista (TM) and Linux guests with Logical
Volume Manager are supported only for recent ESX host and VMware Tools versions
. Refer to vCenter documentation for supported configurations."
faultCause =
faultMessage = (vmodl.LocalizableMessage) []
uncustomizableGuestOS = 'rhel6_64Guest'
Now this customization problem goes away if the VM is just rebooted once. After that we can do the guest customization.
But this reboot takes around 30 seconds of time and for our case , we need to get VMs up and running faster than this time.
Any body who faces similar problem and has some context on it will be very helpful.
Also I don't understand how rebooting the VM solves this problem.
Please share your thoughts even if you don't have exact solutions .
On further Investigation I found that open-vm-tools does not work until the VM is powered on atleast once.
When Machine is powered on , the HOST system detects the open-vm-tools running on guest OS , and from there on open-vm-tools works.
So open-vm-tools can not be used for initial provisioning as it will just not work at the start up.
Cloud-init is the alternative solution which should be used for initial provisioning.
I developed an android based hybrid app in the IBM MFP-7.0., My app is fetching the data from the Java service which is running in Tomcat Server. Here the app adapters are running in my local system MFP server to get the data from the Java service, So that I can only run the app in my local system android emulator. Now, we want to deploy the app in the cloud so that we can give this app to our users. Can some body help me how to run our MFP app in the cloud? Is it required to place eclipse in the cloud to run my MFP server like the way I am running in my local system?
Thanks in advance.
It looks to me like your understanding is completely lacking in this subject matter. Also note that this question has got nothing to do with programming.
You need a host machine. On this server you will run an application server (Tomcat, WebSphere Full profile, WebSphere Liberty profile - either single or a farm, depending on your required network topology and security & scalability needs).
On this application server you deploy MobileFirst
You will also need a database
This host machine needs to be accessible (with appropriate security) to the public Internet so that it could serve apps installed in end-users' devices
The application needs to be configured to send requests to the server (or to any front-side server like a Load Balancer, again, depending on your topology)
The generated application needs to be submitted to an App Store so that users could download and install it on their devices
I suggest that you will do some reading before asking any question. Since you're using IBM MobileFirst, start by reading the user documentation: http://www-01.ibm.com/support/knowledgecenter/SSNJXP/welcome.html
I am building worklight project using eclipse environment when i run the project , i need to connect my tablet to local network then only i works for me for all the server updates and all.
I just want to move worklight server on http server which i can access using http://publicurl/anyprject which runs on apache. Now i want to work on eclipse but whenever i deploy the project it should deploy on public so that i can access it from anywhere.
Just tell me the process and what the thing i need to move on public server.
Since you've come here to ask a question, please also take a moment to write properly structured and coherent sentences in English. This will only benefit everyone and you will get a better answer, and faster too.
Try the following:
Instead of choosing Build All and Deploy, try choosing Build for Remote Server; there you should input the external (public) IP address of your machine. Next, run the generated project in your device. This should allow it to connect to the Worklight Server.
Note that both the Worklight Server (or rather, the machine that hosts it) and the device must be on the same network, in this case - connected to the public Internet.
Based on your comment, you can:
I would seriously try to open your own machine to public access
If not possible, I would try to move to develop on the Linux machine instead
If not possible, then you must install Worklight Server on the Linux machine and whenever you make changes to the project - deploy the updated .war, .wlapp and .adapter files to your installation on the Linux machine
Build the app with Build for Remote Server so that it will connect to the Linux machine instead of the local development machine
Step 3 above means you'll need to maintain 2 development environments, which is not so easy.
If you are during development, you should aspire for options 1 or 2; in other words, create a proper development environment. In Mobile, this requires public Internet access (usually).
Are you a stand alone developer, Business Partner or a Customer of IBM?
What is your preferred development environment ?
Native
WAMP/MAMP/LAMP (Apache, MySQL, PHP) on Windows/MacOS/Linux
Working copy local, SVN/CVS on server
IDE/Editor on the same system (Eclipse, Aptana, Zend...)
Virtual/Native (Server on VM)
LAMP on VirtualBox/VMware
working copy in the VM
IDE/Editor on host, access to the VM with Samba, FTP, SFTP (eventually mapping with tools like WebDrive)
Virtual (VM)
Complete development environment running in a VM (server, tools, IDE)
Host is only used for special tools not available on the OS running in the VM
All have pros and cons.
With BitNami stacks you can run the exact same XAMP environment locally or remotely (and make sure everybody on your team is running the exact same stack). It is free and works on Windows, Linux, Mac.
I like having the SVN repository somewhere on a web server.
It's reasonably secure (using Apache WebDAV), and it gives me a good chance of recovering quickly from any disasters that may befall my main development machine. I have the luxury of control over my own web server, but there are lots of cheap hosts that will do the job at low cost.
As regards VM or no VM:
Advantages of VM - very fast recovery from screwing up your development environment
Ability to try out different versions or upgrades quickly
If you have many systems running the VM host, ability to quickly move the whole environment
Can choose any Host
Disadvantages of VM - performance impact; extra setup complexity.
On balance, I go for "no VM" if all the tools are available on my host system, but I do use VM when I need to run a different OS (the host system is a Mac Pro, so if I need Visual Studio, I do it with Parallels).
