How to run Liferay with EnterpriseDB’s PPAS as WCM

27/02/2014 1 comment

In case you are evaluating a database for your project(s), you might come across an EnterpriseDB’s Postgres Plus Advanced Server (PPAS). This database is part of an EnterpriseDB (EDB) offering, which is a company providing optimizations, support, performance and security additions and tools (such as Oracle compatibility) for Postgres SQL database.

Lately I had a need to use a database for my Liferay portal other than the one that is bundled within Liferay installation, so I have picked up EnterpriseDB’s PPAS. Read more…

Liferay multi-tenant topology using Portal Instances with Amazon S3

Liferay supports multi-tenant configurations via multiple portal instances in a single web container. What is the Portal instance? It is a Liferay’s feature which allows you to have two or more separated user spaces under one physical installation. It simplifies the deployment and administration. Liferay also provides a Properties Override capability to override default properties file so each Portal Instance can have it’s own properties file. As you might know, settings for Documents and Media are put in properties file.

In this article we will look at options to setup multi-tenant deployment (using Portal Instances) for document management system with repository at Amazon S3 and Read more…

How to run Sencha.io examples

17/09/2013 Leave a comment

Although deploying and executing Sencha.io examples should be a basic operation, I faced some difficulties, when setting them up according to the existing documentation. There is a couple of details that I had to do in addition to complete the process successfully. Hence, I decided to summarize my findings in this articles. I hope, they will help you to start with Sencha.io faster.

I got stuck on the “Choose login type” screen, when running the example application according to the docs (see Running the Application), even though I followed all the preceding steps. There was no button or login form, only blank space. The following helped me to work the issue around.

Document versioning in Liferay and Amazon S3

23/07/2013 Leave a comment

Liferay Portal is an enterprise collaboration platform with document management system. It supports multiple users to have access to the same files. Making a mistake, while editing a file represents a risk for all the users. What if someone deletes an important part of a text? Is it definitely lost? No, it isn’t. We can rely on Liferay’s versioning system to address this concern. But, what if you use an external system as your document management repository (such as Amazon S3) that provides an own versioning capability too? Which versioning you should rely on then? The article below gives some insights to Liferay and Amazon S3 versioning. Read more…

Setup Amazon S3 to Liferay with data migration

24/06/2013 2 comments

We slightly introduced Amazon S3 and its basic integration with a clean Liferay installation in a previous article. What should you do, if you have already uploaded files in Liferay and you want to move them from local storage to Amazon S3? Files that are uploaded to Liferay’s local storage will become inaccessible, if you just perform the steps described in the previous article. That’s because the procedure configures Liferay to use Amazon S3 instead of its local storage without moving files that were originally uploaded to the local storage. Attempts to access those files will result to an Internal Server Error. Is it possible to move these files? Yes, it is. Does data migration affects their settings? No, file settings stay untouched. Here is a short intro on how you can migrate files using the Data Migration Tool. Read more…
