Configure the Server-to-Server Distributor

Procedure

  1. Access Historian Administrator on the source Historian server.
  2. Select the Server-to-Server distributor from the list of collectors, and then select Configuration.
    The Collector Specific Configuration (ServerToServerDistributor) section appears.
  3. Provide values as specified in the following table, and then select Update.
    Field Description
    Source Server The source Historian server that you want to use.
    Alarm Replication Indicates whether you want all the alarm data to be transferred from the source server to the destination server. If you enable alarm replication, you must also enable alarm recovery. However, if you set the Max Recovery Time value to zero, alarm recovery does not happen.
    Message Replication Indicates whether you want message data to be transferred from the source server to the destination server. If you enable message replication, you must also enable message recovery. However, if you set the Max Recovery Time value to zero, message recovery does not happen.
    Calculation Timeout (sec) The maximum time allowed for a tag's calculation formula to execute before being terminated. The default value is 10 seconds.
    Max Recovery Time (hr) The maximum duration, in hours, for which the collector will attempt to restore data during recovery logic. The default value is 4 hours.
    Add Prefix to Messages The prefix to identify replicated messages on the destination.

    Alarms and events data will automatically have a prefix added to it with the following syntax: MachineName_Datasource

    For example, if your alarm is forwarded from the server Almserver12 with a data source named OPCAE, the prefix will be Almserver12_OPCAE.
    The Server-to-Server distributor is configured.
