Upgrading websphere from v6 to 7 - what is the best approach - websphere

Hi
we are upgrading websphere application server(WAS) from v6.x to 7.x
currently WAS is installed at:
/usr/IBM/WebSphere/AppServer - default location.
What is the best way to upgrade to 7.x, and recreate profiles with least downtime?

If you are talking just about WAS with no extra IBM products (like Portal, Quickr, Connections, etc) on top of it your best off setting up a new fresh one next to your old one and manually making the configurations (data sources etc). It takes only couple hours to install and update one and if your applications have decent documentation about their requirements it shouldn't take more than a few hours to set up the rest... Then you can simply test it and redirect the traffic.

What releases of ODL have l2switch working?

I am new to ODL. I'm using Northbound Networks ZodiacFX switches to learn with.
All the tutorials I read are written on the basis that l2switch is up and working. Without this working I have to manually build all flow table entries to allow basic switch connectivity.
1) What versions of ODL have this feature available
2) Why was proactive l2 switch programming feature removed from ODL?
Thank you.
l2switch was removed in Fluorine, so any version before that (Oxygen would be
the most recent) should have l2switch.
It was removed because the project no longer had an active community. It would
be welcome to revive if there were contributors willing to do the work.

How I can install varnish cache in my app openshift?

I need to install and set up step by step the varnish cache in an application in OpenShift , but I do not know where to start and not the steps for this. Can anyone help ?
If you mean OpenShift Online in current production version, it's older version 2.x, based on RedHat's own container technology.
If you have OpenShift Origin or OpenShift Enterprise or OpenShift Online Developer Preview, probably it's version 3.x, and it's based on Docker.
You can definitely tell which version are you using by looking at CLI tool's name. If it's rhc, it's older version 2.x, if it's oc, it's newer Docker based.
For newer Docker base, you should be able to deploy any docker image, so varnish should be no problem at all.
You just have to build your own docker image and follow OpenShift tutorial to deploy it on your platform.
I started to play with it, but don't have enough know-how to provide you with step-by-step tutorial right now, maybe in a week or so.
However, if you are using older public version of OpenShift Online, I have a bad news for you.
I've tried to compile static version of varnishd, no luck till now. And I'm not going to try anymore, because fully static version of varnishd is not possible at all, as it's based on dynamically loading of compiled VCLs, thus should be dynamically linked to OS libraries.
And this could be a bit hard to achieve. You have to match correct versions of OS libraries and still it's fragile as it could possibly break after upgrade of underlying OS.
I wouldn't try this in production.
I suggest you to try another could provider, either IaaS solution with full OS with varnishd installed from packages, or choose any Docker hosting provider.
Or, if you can afford it and it's worth for you, you may try http://fastly.com/, a CDN provider.
Their technology is based on customized older version of varnishd, with easy to use GUI, a lot of fancy built-in stats, etc... But the most important feature is you can deploy your own VCLs upon request. If they enable it to you, you can upload new VCL in few seconds.
Good luck.

Making a case for Kentico 9 vs 8.2

We will be developing a new web site for a client who already has a Kentico 8.2 license. I am trying to make a case for developing the site using Kentico 9. Some key features I have found so far include:
faster performance (how much in real-world terms?)
better integration with .Net MVC
content staging tasks can be synchronized per user account
better rollback functionality: previously we had to make full database backups, content staging in Kentico 8.2 causes issues for restoring previous versions of a page.
built in source control support for GIT
It looks like Kentico integration with the client's existing database may be possible. Has anyone done this? What are the limitations or caveats?
Is there a discount for upgrading the license from 8.2 to 9?
Thanks in advance for your feedback!
faster performance (how much in real-world terms?)
there are major (official) improvements for content and contact management
better integration with .Net MVC
there is whole new way to develop sites using ASP.NET MVC with Kentico
content staging tasks can be synchronized per user account
there is pretty good blogpost describing new staging improvements
better rollback functionality: previously we had to make full database
backups, content staging in Kentico 8.2 causes issues for restoring
previous versions of a page.
I am not sure what do you mean by new rollback functionality
built in source control support for GIT
you might confused with continuous integration feature
You can find release notes with all new features and improvements here.

there is tested upgrade utility for upgrading to Kentico 9
Is there a discount for upgrading the license from 8.2 to 9?
for pricing you should definitely contact Kentico sales department
See the answer I posted on the DevNet (which by the way, no need to cross-post on both)
If they have a license for 8.2, is their maintenance current? If so, simply go to the client portal and upgrade it for free. This can be done without any cost. Either way, the licensing cost doesn't come from the version, it comes from the type (base, ultimate, ems, etc.).
So assuming they purchased their license about a year ago, their maintenance should be current or close to current and you either get current on your maintenance or just go to the client portal and see if it will allow you to upgrade your license and get a new key for v9.
If they don't have the site built, there is no reason to build it on v8.2 at all.

Magento: Are there stats on install base (by version) for module developers?

As the question states, I am preparing to deploy my first couple modules on the Magento Connect store and want to make sure I am targeting the best versions. Testing on 1.3 is proving to be a bit of a pain, and if only a few people use that version I would rather spend the time making the modules better!
Google hasn't helped as yet, though I think the keywords I use are getting picked up as other more specific technical questions (Google Base, for example).
Does this information exist? What about your personal experience? For me, I have only encountered installations below 1.5 Community (1.10 Enterprise) for upgrade projects. I haven't personally encountered a client that is on 1.4 and plans to stay on 1.4.
Thanks!
Tim
There are a signification amount of people who have older versions and wont upgrade because of the complexity and the amount of modification they have done to their stores.
Most people right now who are on community version seem to be on 1.5 or 1.6, but if you want to test older versions just download from the archive install locally and see if it works for the older versions.
Here is a link to the downloadable versions of magento, in case you decide to test on those older versions:

CouchDB on Windows?

I started exploring CouchDB and I am interested in following:
Is there or will there be a Windows install?
If there is, is there a shared hosting provider that offers CouchDB?
Not knowing much about it, can it be somehow embedded in my application or bin deployed (don't laugh).
The most reliable source is the CouchDB download page
There are several places offering CouchDb hosting. Besides Cloudant, you can use most Infrastructure-as-a-Service parties like Google, AWS, etc.
This question was asked (and answered) elsewhere on StackOverflow here and here.
There's a Windows version now, available on CouchIO (http://www.couch.io/get) blog.
Download & Unzip
Double-Click bin\couchdb
Relax!
Visit http://127.0.0.1:5984/_utils
There's been a fully compatible Windows build of CouchDB shortly after every source release, since the initial 1.0.0 release over 18 months ago. You can get this directly from the Apache CouchDB mirrors http://couchdb.apache.org/ now.
NB the embedded test suite is actually for developer testing; due to subtle timing constraints not all tests will pass first time round on every machine. In the next release of CouchDB, the tests will be done outside the browser which will be both simpler and more robust.
Please up-vote this so we have the right information to hand.
Since this question was posted, there is a Windows download available at https://couchdb.apache.org/ .
