Introduction

documentsmediadatabasechecker
The Documents and Media File System Checker portlet was developed by XTIVIA, the 2012, 2013 and 2014 Liferay North America Partner of the Year. As we work with Liferay customers, we often run into situations where the client has a Liferay environment (from test all the way to production) with an inconsistent data set for the documents and media functionality. The preferred Liferay configuration is to store the meta-data about documents and media in the Liferay database and to store files on the file system. Due to various reasons this data can get into an inconsistent state, for instance:

  • You may be moving data from one environment to another (for example, from production down to QA and test). If you accidentally copy the database backup from yesterday and the file system backup from today and in the interim, users have uploaded new files to the production system.
  • You run a LAR export from one environment and import into another, but due to various reasons (from a Liferay defect to a buggy customization done by you) you end up introducing inconsistent data.
  • You accidentally delete a file on the file system to free up disk space.

To help you detect and resolve these data inconsistencies, XTIVIA developed this plugin. The Documents and Media File System Checker portlet provides a dashboard view of all the missing documents in the file system that have a corresponding file entry in the database. It also enables the user to list all the documents residing in the file system that are in synchronization with the database, as well as all the missing documents in file system that have a representation in the database.

The listing is displayed in a data table that enables the user to navigate through the dataset, to sort the dataset multiple ways, and to modify number of documents per page. Apart from this, the user can create a dummy file in the file system for missing documents pertaining to each of the missing documents listed so as to re-establish consistency between the Liferay database and the file system.

Note: Please note that this plugin is intended to work with the File System Store. See here for more details.

Key Features:

  • List missing documents in the file system (that have a corresponding file entry in the Liferay database) as the default view.
  • List all documents in the file system (that are in synchronization with the database) along with the missing documents in the file system.
  • Resolve missing documents in file system using the action – Create dummy file in File System.
  • Navigate through the data set
  • Sort documents
  • Modify number of documents displayed per page.
