Alfresco – Share Clustering fail with ‘Ignored XML validation warning’

By | Application integration & Middleware, Entreprise content management | No Comments

In a recent project on Alfresco, I had to setup a Clustering environment. It all went smoothly but I did face one single issue with the setup of the Clustering on the Alfresco Share layer. That’s something I never faced before and you will understand why below. Initially, to setup the Alfresco Share Clustering, I used the sample file packaged in the distribution zip (E.g.: alfresco-content-services-distribution-6.1.0.5.zip): <?xml version=’1.0′ encoding=’UTF-8′?> <beans xmlns=”http://www.springframework.org/schema/beans” xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xmlns:hz=”http://www.hazelcast.com/schema/spring” xsi:schemaLocation=”http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd…

Alfresco Clustering – Solr6

By | Application integration & Middleware, Entreprise content management | No Comments

In previous blogs, I talked about some basis and presented some possible architectures for Alfresco, I talked about the Clustering setup for the Alfresco Repository, the Alfresco Share and for ActiveMQ. I also setup an Apache HTTPD as a Load Balancer. In this one, I will talk about the last layer that I wanted to present, which is Solr and more particularly Solr6 (Alfresco Search Services) Sharding. I planned on writing a blog related to…

Alfresco Clustering – Apache HTTPD as Load Balancer

By | Application integration & Middleware, Entreprise content management | No Comments

In previous blogs, I talked about some basis and presented some possible architectures for Alfresco, I talked about the Clustering setup for the Alfresco Repository, the Alfresco Share and for ActiveMQ. In this one, I will talk about the Front-end layer, but in a very particular setup because it will also act as a Load Balancer. For an Alfresco solution, you can choose the front-end that you prefer and it can just act as a…

Alfresco Clustering – ActiveMQ

By | Application integration & Middleware, Entreprise content management | No Comments

In previous blogs, I talked about some basis and presented some possible architectures for Alfresco, I talked about the Clustering setup for the Alfresco Repository and the Alfresco Share. In this one, I will work on the ActiveMQ layer. I recently posted something related to the setup of ActiveMQ and some initial configuration. I will therefore extend this topic in this blog with what needs to be done to have a simple Cluster for ActiveMQ….

Alfresco Clustering – Share

By | Application integration & Middleware, Entreprise content management | No Comments

In previous blogs, I talked about some basis and presented some possible architectures for Alfresco and I talked about the Clustering setup for the Alfresco Repository. In this one, I will work on the Alfresco Share layer. Therefore, if you are using another client like a CMIS/REST client or an ADF Application, it won’t work that way, but you might or might not need Clustering at that layer, it depends how the Application is working….

Alfresco Clustering – Repository

By | Application integration & Middleware, Entreprise content management | No Comments

In a previous blog, I talked about some basis and presented some possible architectures for Alfresco. Now that this introduction has been done, let’s dig into the real blogs about how to setup a HA/Clustering Alfresco environment. In this blog in particular, I will talk about the Repository layer. For the Repository Clustering, there are three prerequisites (and that’s all you need): A valid license which include the Repository Clustering A shared file system which…

Alfresco Clustering – Basis & Architectures

By | Application integration & Middleware, Entreprise content management | No Comments

This blog will be the first of a series on Alfresco HA/Clustering topics. It’s been too long I haven’t posted anything related to Alfresco so I thought about writing a few blogs about my experience with setting up more or less complex HA/Clustering infrastructures. So, let’s start this first part with an introduction to the Alfresco HA/Clustering. If you want to setup a HA/Cluster environment, you will have to first think about where you want…

SQL Server availability groups, SQL Browser and Shared Memory considerations

By | Database Administration & Monitoring, SQL Server | One Comment

Few weeks ago, my colleagues and me discussed availability groups and network considerations for one of our customers including disabling SQL Browser service and shared memory protocol. The point was disabling both features may lead to unexpected behaviors when creating availability groups. Let’s start with the SQL Browser service. It is not uncommon to disable this service at customer shops and to use directly SQL Server listen ports instead. But if you go trough the…

Convert a WebLogic Cluster from configured to dynamic

By | Application integration & Middleware | No Comments

Unless the servers in cluster are not symmetric, which is not recommended anyway, dynamic cluster have many advantages against configured cluster:

Ensure Cluster Member Uniformity
Easily add new servers to manage more traffic
Automatically adapt to load to add/remove managed servers
Can still contain configured servers even if not recommended as for point 1
