Main features in OCEE

  • Support for multi-staging scenarios with the OCEE Replicator: You can configure a "development" server that first pushes all generated content to a "staging" server e.g. for approval, and then afterwards to the "delivery" server. This is freely configurable, and there is no limit on the number of stages.
  • Centralized configuration of servers with the OCEE Cluster: You can now edit the scheduled jobs, search index configuration and module parameters for all individual servers in the cluster from a common GUI in the workplace server.
  • Support for OpenCms OUs in the LDAP Connector: It is now possible to connect each OpenCms OU with an individual path in the LDAP Server.
  • Improved performance with the OCEE Accelerator: A much improved cache policy in the Accelerator now selectively flushes only certain cached items after publishing instead of just flushing everything.
