Using the Alkacon OCEE Replicator it is possible to replicate the complete (or part of the) OpenCms repository data to remote database instances. These remote instances are also automatically updated when changed data is published. Using this feature, it is for example possible to have a separate internal OpenCms “work server” instance inside of a secured intranet, and a public OpenCms “production server” in a DMZ.
Please see the compatibility notes for the list of databases compatible with this OCEE module.
Please note: Replication is done only in one direction, so in the above example, no content can be created on the public “production” server in the DMZ.
Please note: The OCEE Replicator is compatible with OpenCms 22 and later versions. However, it cannot be used with the optimized DB storage layer introduced in OpenCms 22. An OpenCms installation can use either the OCEE replication or the storage layer, but not both at the same time.
