How to scale up a Patroni cluster

By | Database Administration & Monitoring | No Comments

During the preparation of my presentation for the pgconf.eu I ran into one big issue. I had to stop my cluster to add a new node. That was not the way I wanted to archive this. I want a high availability solution, that can be scaled up without any outage. Due to a little hint during the pgconf.eu I was able to find a solution. In this post I will show the manually scale up,…

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 2019 availability group R/W connection redirection, routing mesh and load balancing

By | Database Administration & Monitoring, SQL Server | No Comments

SQL Server 2019 availability group feature will provide secondary to primary replica read/write connection redirection. I wrote about it in a previous blog post here. It consists in redirecting client application connections to the primary replica regardless of the target server specified in the connections string. That’s pretty interesting in some scenarios as read scale-out or specific multi-subnet configurations where creating the traditional AG listener is not an viable option. The new R/W connection redirection…
