Using the CMIS Store

Though you can mount as many different CMIS (Content Management Interoperability Services) repositories as you like in the Documents and Media library, you can also define the Liferay DXP repository to point to a CMIS repository.

Note: CMIS Store is not suitable for production use and is deprecated as of Liferay DXP Digital Enterprise 7.0 Fix Pack 14 (SP3) and Liferay Portal CE 7.0 GA4. Because it can have performance issues with large repositories, it’s recommended that you use one of the other configuration repositories listed above, such as Advanced File System Store, to store your Documents and Media files.

To use the CMIS store, follow these steps:

1. Configure portal-ext.properties with this property:

   dl.store.impl=com.liferay.portal.store.cmis.CMISStore
   

2. Restart Liferay DXP.

3. In the Control Panel, navigate to Configuration → System Settings → File Storage.

4. In the CMIS Store screen, configure the store your way.

5. In the CMIS Repository screen, configure the repository your way.

6. Click Save.

7. Restart Liferay DXP.

The Liferay DXP repository is connected to CMIS via the CMIS store. As long as all nodes are pointing to your CMIS repository, everything in your cluster should be fine, as the CMIS protocol prevents multiple simultaneous file access from causing data corruption.
