Prepare to install AVEVA Historian

A complete AVEVA Historian system consists of the following software components:

• Microsoft SQL Server

• Historian program files, database files, and history data files

• Operations Control Management Console, the configuration and control tool

• One or more local or remote IDASs (I/O data acquisition service) – at least one must be defined

• Historian documentation.

You should have a definite plan for implementing the Historian in your plant environment before you start the installation process. This plan should include the type of network architecture for the Historian system, the amount of disk space required for data storage, and the amount of space required for the Historian database files and log files.

Also, any administrative security accounts that you specify for either the Microsoft SQL Server or the Historian should be accounts that do not change often, if ever. In particular, do not change an administrative password during any part of the installation process.

You must have administrative rights on the local computer to install the Historian. The account with which you log on to the computer must also be a sysadmin for the SQL Server or you must be able to provide a sysadmin account for the SQL Server when prompted for it during the installation.

The installation program detects any previous versions of the Historian and notifies you of your migration options.
