About Installing the Historian Server for the First Time

About this task

You can choose one of the following types of installation:
  • Single server: This is for a stand-alone Historian system, which contains only one Historian server. This type of system is suitable for a small-scale Historian setup.
  • Mirror primary server and distributed/mirror node: This is for a horizontally scalable Historian system, which contains multiple Historian servers, all of which are connected to one another. This type of system is used to scale out the system horizontally. For example, if you have 5,00,000 tags in your Historian system, you can distribute them among the various servers to improve performance.

    In this setup, one of the nodes acts the primary server, whereas the others are the distributed/mirror nodes.

For all these types of installation, you can use the GUI-based installer or the Command Prompt window. You can also install Historian in a clustered environment.

This topic provides the high-level steps in installing the Historian server for the first time. You can perform the same steps to upgrade the server. However, before you upgrade, refer to the things to remember.

Note:
  • The number of alarms in the Historian Alarms and Eventss database, and the frequency of new events being added during the installation, impact the time it takes to install Historian. For example, an installation for a system with 1.5 million alarms can take up to three hours to complete.
  • To add a component, re-run the installer and select the check box for that component. Do not clear the check box for previously installed component. If you do so, it will be uninstalled.
  • Collectors will appear in Historian Administrator only when they are started.
