Chapter 2. Requirements for Clusters Used With Data Lifecycle Manager Engine

The clusters on which you install the Data Lifecycle Manager (DLM) Engine must meet the requirements identified in the following sections. After the DLM Engine is installed and properly configured on a cluster, the cluster can be used for DLM replication.


Clusters used as source and destination in a DLM replication relationship must have exactly the same configurations for LDAP, Kerberos, Ranger, Knox, HA, etc.
