It seems Neo4J High Availability is only available for the Enterprise edition which is paid- is there another alternative to achieve replication without that module? (i.e. without cost). Thanks for any help!
Update:
This answer has changed. Neo4j is now open core, so the Enterprise code is no longer dual-licensed - only the commercial license option remains.
You can find more details here: https://neo4j.com/open-core-and-neo4j/
Original Answer:
Enterprise is available as quid-pro-quo - if you put your code out under an open source license, then you get access to the open source Neo4j Enterprise free of charge. However, if you are closed source, Neo Tech charges a license fee. This fee is determined by your needs and your ability to pay - if you are a small outfit with no venture capital, it's still free, and then the licensing cost increases as your ability to pay back to the development of Neo4j increases.
If your application is open-source as you mention, then you are free to use Neo4j Enterprise without paying for it, simply download it at neo4j.org.
Actually Neo4j Enterprise is free under the open source AGPLv3 license.
Neo4j Inc can't modify the terms and still call it AGPL.
If you use Neo4j Enterprise as a server (like most people do) and communicate with it via its REST API or any of the official BOLT drivers then you never trigger AGPL's copyleft requirements.
In other words - the software that connects to it does not have to be open sourced.
You can download Neo4j Enterprise open source licensed binaries up to version 3.2.x from dist.neo4.org. The links for the windows and unix packages are below. (Replace the version number for specific versions)
http://dist.neo4j.org/neo4j-enterprise-3.2.8-windows.zip
http://dist.neo4j.org/neo4j-enterprise-3.2.8-unix.tar.gz
If you want Neo4j Enterprise 3.3.0 and on under it's free open source license, then you can build them from source like we do for our US government clients, or just grab them from our free distribution site.

We are working with a client who is interested in developing a application using Corda Ledger. While in the initial phase of development to first rollout in to Production, client is looking to see the capabilities of Corda Ledger using its community version. Subsequent to first Production rollout when the capabilities of Corda are on the display with its own client, they want to look beyond making this solution a enterprise solution using by procuring Corda enterprise license.
I am not getting much help in forming a delineating line of difference between Community and Enterprise version of Corda.
**What are essential features which cannot be built using community version ?
**who governs Community version ?
**Is there any support provided for Community version ?
**Can we create a distributed architecture using Community version (Corda nodes located on different physical servers) ?
**Can we create Corda network using Docker containers using Community version ?
**Is there any detailed document to draw the lines between community and enterprise version ? **
I have worked on community version of Corda using it for developing PoC, Where all nodes are located on same server and were not truly distributedstrong text
Corda Open Source and Enterprise are functionally identical. What Enterprise offers extra is the non-functional stuff that is required for mission-critical enterprise applications, which includes performance, HA, HSM integration, Enterprise Database integration, 24 X 7 Support, etc.
The community version id developed primarily by R3, while we also accept and encourage community contribution to the Corda Open Source project.
There is no Official R3 Production Support for Open Source Corda, however, you could ask questions and ask for solutions to your problems on our public slack channel (stack.corda.net) and also here on StackOverflow.
You can operate a network of OS Corda with nodes on different servers without any problems.
MariaDB TX is the name of MariaDB's enterprise version and is comparable to MySQL Enterprise, and it seems to be a rather new product, as it's not mentioned at all on the MariaDB wiki page.
They seem to have a focus on GDPR and personal privacy, with features such as database encryption, auditing, data protection, threat detection/prevention.
But what I can't figure out is what do I get from using the free version of MariaDB and what features are missing out, that are important from the aspects of GDPR.
What are the differences between the two, and is the free edition good enough to increase the security, perhaps by add some other free external applications to do auditing and threat detection?
If you need GDPR, you need help; it would be folly to try to do it with any free product.
If you are storing sensitive information, you need help. I cringe when anyone asks for free help on this site, and mentions the existence of SSNs, Credit Card numbers, etc. It is much easier to get free hacking tools than free protection tools.
Other than that, there is a lot that can be done with MariaDB and MySQL. The free versions are fine for individuals and small companies (except for sensitive info). Most of the major web sites are powered by some version of MySQL.
Since you have not spelled out what your app will do, I can't be more specific.
MariaDB TX is a solution, not a single piece of software. It is a collection of software and tools that provides a complete database solution [sic] and one of those is the MariaDB Server. They use the same packages and source code as the "free" MariaDB version (all versions of MariaDB are free) so it has the same features.
A good, practical view of the software in MariaDB TX can be seen on the TX Downloads page. You see the MariaDB server, MaxScale, connectors and tools.
I've seen this question but the answers are simply not good enough. I've searched the web and could find a clear listing of the main differences.
I am particularly surprised to see contradictions in the above link, that holds only 4 short answers.
So the question is, beyond support, what are (all) the differences between Alfresco Community and Enterprise editions (for the current versions of course)?
Are there functional or technical features that available in the Enterprise edition, that are not in the community edition?
I find it strange that it's so difficult to get a clear list. Looking at the forums to find this answer is not a serious option from a business perspective.
Until now, I found this link to be useful, but it's from 2009.
In particular, I find the platform support interesting, with the community edition supporting only lamp stuff:
Linux
MySQL
Tomcat
OpenLDAP
Firefox
And the enterprise edition supporting:
Windows
SQL Server
WebLogic, WebSphere
AD/Kerberos
IE and Safari
Apparently, these features are only available in the enterprise edition:
JMX monitoring
Runtime admininstration: What's that exactly? And what's in the community edition then?
Runtime indexing consistency check and update: What's in the community edition then?
High performance and availability: How is that implemented and what's in the community edition then?
Storage policies
Open source and proprietary technology stack support: which ones exaclty? Which ones are supported in the community edition?
If anyone could guide me towards serious documentation about these differences, that would be great.
I also went through the wiki but could not find an answer to my questions in there.
differences between Enterprise and Community vary in detail from version to version and are mainly visible for administrators. We see or maintain both flavors of Alfresco in midsize to very large environments and I would say it's more or less a question of taste and budget what the best decision / edition is for you. Excellent skills in infrastructure and java are highly advisable for both editions to run Alfresco in production.
The technical differences are not as dramatic as not being able to provide very similar functionality for the users - so if you're actually in a decision you should focus on a good technical partner, the support services and maybe the fact that you only get official patches in the Enterprise subscription, not on the Community. BTW Alfresco Enterprise is not Open Source but this is not a real point of interest for most end users. You can access the code as a subscription customer but it is not public available/accessible.
The main differences in features are already named more or less:
Administration
Enterprise has more views and setting in the admin web GUI. In Community you can access most configuration only from the command line. This may be a restriction but in real live Administrators prefer the command line and scripting automation.
Enterprise lets you change some Alfresco settings during runtime (most settings still require restart). Some can be change in the GUI and more in the jmx interface. Also you're able to stop and start subsystems like the CIFS protocol server. We use this feature to switch a system in read only mode. This point is meant with "runtime admininstration". Community requires restart of the service for most configuration changes. It is possible to work around this by advanced scripting like groovy or by implementing modules.
Indexing
Runtime indexing consistency check and update is not a self healing functionality as expected. You will have to learn (at least for now) that you have to recreate the Alfresco index from time to time even in Enterprise environments and that it is better to focus on good strategies how to speed recreation or how to setup standby indexes instead of hunting failed indexing transactions using the check and update methods. For major document model changes you need to recreate the index anyway.
High performance and availability
This is mainly the cluster and replication functionality which is no longer available in Community. It's similar to MS Clusters: It's a lot, lot work for very view more availability since some concepts are missing. The price is high in terms of complexity and can end up in loss of robustness. Even with enterprise support it's a hard job to keep a alfresco cluster running - so you need very good arguments why to go this way. But of course: its possible and available!
High performance: There shouldn't be any difference and if - I'm very curious about the explanation.
Technology stack
The main difference is the database support. In the Community you only can choose between MySQL and Postgres (No Oracle or MS SQL for Community). All other technologies are independent from Enterprise or Community (AD, Kerberos, OS, Browser, ...)
Java Container: I believe over 95% of all Alfresco installations run in tomcat. That's the configuration which is documented, tested and scales. Using WebLogic or WebSphere gives you no added value except new challenges - quite the contrary: You have to solve most issues for yourself and can't benefit from others experience.
Storage policies: I'm not pretty sure and should check in 4.2.x if the Content Store Selector / Storage policies is no longer available in the Community, but it was there in the 3.x versions.
[Edit]: storage policies have been removed in Community 4.2.x:
NoSuchBeanDefinitionException: No bean named 'storeSelectorContentStoreBase' is defined
If there is a really need for this functionality someone may re-enable that feature by coding a module for Community.

This page explains the difference between the editions:
https://wiki.alfresco.com/wiki/Enterprise_Edition
This page is the canonical, comprehensive list of the differences.
If you are considering an Enterprise Subscription and you have a question that isn't answered by what you can find on that page, you should talk to your account rep.
Well, regarding JMX monitoring:
Runtime administration: Alfresco enterprise allows to perform certain actions on Alfresco subsystems without restarting the server. This allows you to be very fast during debugging/developing and also making changes in production environment. Also you can access the JMX interface that supports JMX Remoting.
There is no consistency check or update, until you restart the server (during the startup you have to validate/check/rebuild your indexes). There is an option in alfresco.global.properties (or the original repository.properties config file) for that. If you have some inconsistencies in the Alfresco Community index, you're gonna have a bad time xD.
Alfresco Enterprise has specific license for clustering your architecture, the Community edition doesn't support those systems. Replicate and cluster Alfresco is one of the main improvements in performance/scalability/availability you could achieve.
The storage policies allow you to use Content Store selectors in Alfresco Enterprise. You can manage a primary and a secondary file store, and map/connect these stores in your architecture. The Community Edition allows you only to use one content store at a time.
These include everything inside Alfresco (Spring Framework, Apache-Lucene/Solr, Tomcat, and so on), because with the Enterprise license you have also the full support with everything inside the Alfresco package. The difference is that the Community is based on daily builds, supported by community, and therefor not guaranteed. The Enterprise support helps you resolve many problems that you might encounter during developing and in production environment, not only Alfresco related, but also on some configurations on supported platforms (Windows/Linux), your web application servers, and so on.
Hope it helps.
I tried the usual:
CRX from Day.com: not (yet) stable
KnowledgeTree Community: couldn't get it to work (unless perhaps you buy the commercial version?)
Nuxeo: very, very expensive, but looks good (is there a community version available?)
yet a few more
I also installed Alfresco, which seems to be the best out there in terms of functions it offers; I'm quite impressed by it, to be honest. However, it's very slow, sometimes taking a few minutes to check-in a document. It also takes quite a lot of memory (maybe due to Java?). It also has some issues dealing with Illustrator documents.
Is there a CMIS server available that can connect to Adobe Drive (CMIS) and not running on Java?
I just need the Check-in/out functions through Adobe Drive 2.1 or 3.0 CMIS.
UPDATE [20/02/2012]
After playing with the above-mentioned software for a while, I can (personally) affirm that Alfresco is the best among all (free) available software. I'm running the community version 4.0.d. It seems pretty stable and the installation + connexion to Adobe Drive 3.0.1 via the CMIS connector is seamless; (FYI in Drive: cmis://127.0.0.1:8080/alfresco/service/cmis).
UPDATE [25/06/2014]
#NicolasRaoul is right. CMIS not running on Java, as specified in the title => Nuxeo. Hence #JulienCarsique's answer accepted/upvoted.
About Nuxeo, it is free for use. There's no "community" or "enterprise" versions but a unique Open-Source, free and enterprise-ready version.
To answer your question, there is a CMIS implementation that is not based on Java. It is Microsoft Sharepoint, which also has a CMIS connector. I don't know anything about it's completeness or performance.
Something tells me though that is not the platform you are looking for and it will definitely not run on your Mac Mini.

Are there any restrictions for using coherence.jar without any license?
coherence.jar is open for downloading without any fee.
You can use it for development purposes. Any other purpose means purchasing a license. On the download page is a link to the license agreement that states:
You may not:
use the programs for your own internal data processing or for any
commercial or production purposes, or
use the programs for any purpose
except the development of your
application;
use the application you develop with the programs for any internal data
processing or commercial or production
purposes without securing an
appropriate license from us;
continue to develop your application after you have used it for any
internal data processing, commercial
or production purpose without securing
an appropriate license from us, or an
Oracle reseller;
remove or modify any program markings or any notice of our
proprietary rights;
make the programs available in any manner to any third party;
use the programs to provide third party training;
assign this agreement or give or transfer the programs or an interest
in them to another individual or
entity; - cause or permit reverse
engineering (unless required by law
for interoperability), disassembly or
decompilation of the programs;
disclose results of any program benchmark tests without our prior
consent.
The first two points are the most relevant.
On the Coherence download page it says you need to agree to the Oracle Technology Network (OTN) License Agreement to download the software.
That license contains this text:
We grant you a nonexclusive, nontransferable limited license to use the programs only for the purpose of developing, testing, prototyping and demonstrating your application, and not for any other purpose. If you use the application you develop under this license for any internal data processing or for any commercial or production purposes, or you want to use the programs for any purpose other than as permitted under this agreement, you must obtain a production release version of the program by contacting us or an Oracle reseller to obtain the appropriate license.
So it's a free download only for development purposes. (Most Oracle Products are available free to developers.)
But if you want to use this code in production or in a product you're selling you will need a license.
Have you considered using Infinispan as an open source alternative to Coherence?
Don't forget that the version that you download from the public website is usually just the major release. The minor release, with all the many bug fixes, is only available if you have a support contract.
