copied!<p>Liferay's official documentation recommends sharing Jackrabbit data using a database in a clustered scenario, not the file system. </p> <p>Let's say you're using the file system on each of your Liferay nodes (which is the out of the box Liferay configuration). Node A would not be able to access the Jackrabbit data on Node B and vice versa. As time goes by, the nodes become more and more out of synch. To get around this, you could create a network share and configure each node to point to the share. The problem with doing that is it could result in file corruption if each of the Liferay nodes are writing at the same time. </p> <p>This leaves you with two options; keep independent file systems and integrate a synchronization utility or put the data in the database. Since file system synchronization is hokey at best, your best option is putting the Jackrabbit data in a database.</p> <p>There are some pros and cons of using the database. It could decrease performance, true. At the same time, the data is now part of the regular disaster recovery strategy and some could argue it's more portable.</p> <p>Edit - Addition: An AdvancedFileSystemHook was added at some point in version 5.2 which resolves issues with file corruption and locking concerns when using a shared network file system. In order to implement this, change your portal-ext.properties file to use the AdvancedFileSystemHook, migrate your data to the shared location, point your horizontal nodes to the shared location.</p>
