AdministeringIn addition to administering the database server, you can tune performance, replicate data, and archive data.
Enterprise ReplicationThe describes the concepts of data replication using Informix® Enterprise Replication, including how to design your replication system, as well as administer and manage data replication throughout your enterprise.
Setting up and managing Enterprise ReplicationAfter you design your replication system, you define it and start replication.
Preparing the Replication EnvironmentThe following topics explain the steps that are required for setting up Enterprise Replication.
Preparing the Network EnvironmentYou must prepare the network environment for each database server in an Enterprise Replication domain.
Configuring network encryption for replication serversYou encrypt client/server network communication by specifying the ENCCSM module with the communications support module (CSM) option in the sqlhosts file. 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 older server versions before 14.10xC6, Enterprise Replication requires configuring ENCRYPT_CDR instead of ENCRYPT_SMX.

Configuring network encryption for replication servers

You encrypt client/server network communication by specifying the ENCCSM module with the communications support module (CSM) option in the sqlhosts file. 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 older server versions before 14.10xC6, Enterprise Replication requires configuring ENCRYPT_CDR instead of ENCRYPT_SMX.

You cannot configure an Enterprise Replication connection with a CSM.

To combine client/server network encryption with Enterprise Replication encryption, configure two network connections for each database server. The configuration in the SQLHOSTS file would look like the following example.

#dbservername  nettype   hostname    servicename  options
 gserv1        group     -           -            i=143
 serv1         ontlitcp  ny.usa.com  ertest1      g=gserv1
 c_serv1       ontlitcp  ny.usa.com  ertest10     csm=(ENCCSM)

In this example, serv1 and c_serv1 are two connection ports on the same database server. Encrypted client/server communication uses the c_serv1 port, while encrypted Enterprise Replication uses the serv1 port.

For more information on encrypting client/server network communications, see the Informix® Administrator's Guide.
