How to run Liferay with EnterpriseDB’s PPAS as WCM

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.

Liferay supports multi-tenant configurations via multiple portal instances in a single web container. What is the Portal instance?

Document versioning in Liferay and Amazon S3

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.

Setup Amazon S3 to Liferay with data migration

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.…
