Scaling Terracota - Free and Open Source? - ehcache

Is Terracota ehcache scaling across various nodes open source or is it a commercial product? Apparently, it did not require a commercial licence earlier but it does now.
From http://ehcache.org/ - "For applications requiring a coherent distributed cache as well as in-memory performance, use Terracotta BigMemory Max which is available in both extended trial and full versions. (Terracotta no longer actively updates the open-source version of Terracotta Server Array, also known as Terracotta.)"
Can someone throw some light on it? I find confusing information on the web.

The open source Terracotta is defunct. The team behind it is also gone. But EHCache itself is open source.

Oracle 11g R2 Security patch installation

I have Oracle 11g R2 Free version in my laptop for development purpose, But i need to update the security patches given by Oracle. But while doing it it was taking me to a registration page where they are asking for Support Identifier.
Please help me out with this issue.
I'm not much into licencing, but - as far as I can tell - you get access to My Oracle Support (so that you could download patches, read additional documents, etc.) once you purchase (read: pay (a lot of) money) to Oracle because you started using their software in production.
For free versions, I'd say that you get quite a lot - regarding how much you paid for it (i.e. nothing at all), but shouldn't expect to get additional features as well.
If it is, as you said, for development purposes, why would you care about security patches? You don't trust yourself? :)
Therefore, in my opinion, you're out of luck.

What is difference between Liberty Core,Liberty Base,Liberty Network Deployment versions?

Is there any document which provide information about difference between Liberty Core, Liberty Base, Liberty Network Deployment versions?
I want to use Liberty and deploy my application in Docker Data Center. But I am not sure which version of Liberty should I use. Also what is the main difference between these versions? My applications will have different technology stacks like REST, SOAP, EJB, RPC, Caching, JPA etc.
Is there any document which provide information about difference between Liberty Core,Liberty Base,Liberty Network Deployment versions.
These are called "editions" and each edition includes a set of features. The smallest edition is "core" and it contains the most minimal set of features. Each successive edition adds a few more features, with ND basically including everything (except the zOS specific features).
Here is a chart to help you visualize how the editions relate to one another.
Note that this image is already out of date, because more features have been delivered since it was created.
To see the official table of what features are included in each edition, see Liberty Features.

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.

Is it possible to have basic wan replication for hazelcast open-source edition?

I'm aware that on hazelcast editions comparison page:
https://hazelcast.com/pricing/
it is clearly specified that WAN replication is only for enterprise edition.
But, on the other hand,
this hazelcast documentation is divided into two parts:
https://docs.hazelcast.org/docs/latest/manual/html-single/#wan
Only the second part is explicit about enterprise edition, making one assume
that the first part refers to non enterprise edition.
I also noticed that the parameters are a bit diferent between the two parts:
(com.hazelcast.wan.impl.WanNoDelayReplication vs com.hazelcast.enterprise.wan.replication.WanNoDelayReplication)
I experimented a bit with hazelcast and stuff works as expected.
Only cluster replication over WAN seems to not work with opensource edition - making me thinking that either it is completely absent in opensource edition or I messed up the configuration.
So, even I am almost sure that wan replication is exclusive for enterprise edition, I thought it would be better to ask if anyone managed to use WAN replication with opensource edition ?
Are both editions "WAN replication" enabled while enterprise edition just has extra features ? ... or is it exclusive for enterprise ?
Thank you !
Yes, there is basic wan replication for the open source version. It only supports replication of Maps, other data structures (queues, sets, topics etc) are not replicated.
The documentation link that you've shared should be enough to make a sample.
But please don't forget that Enterprise version has more features (like support for Cache replication in addition to Map, batch replication, etc.) and actively developed.

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

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.
