Configuring network encryption for replication servers
You encrypt Enterprise Replication communication by setting encryption configuration parameter ENCRYPT_SMX or by configuring ER group option for onsocssl port in sqlhosts file. Unless onsocssl port is used for communicating with peer ER servers, for communicating with server versions prior to 2.0.0.0, Enterprise Replication requires configuring ENCRYPT_CDR instead of ENCRYPT_SMX.
For more information on encrypting client/server network communications, see the HCL OneDB™ Administrator's Guide.
