What must occur before administering a Historian Server in the ArchestrA SMC?

Before administering a Historian Server in the ArchestrA System Management Console (SMC), the critical step that must occur is registration of the Historian. Registration establishes a formal connection between the Historian and the ArchestrA system, allowing the SMC to recognize and manage the Historian as part of the overall architecture. This process is essential for proper integration and functionality within the broader system.

Registration means that the Historian becomes a known entity within the SMC, enabling it to be configured, managed, and monitored effectively. Without completing this registration process, the Historian wouldn't be recognized, and no further actions—such as configuration or management—could take place successfully. It sets the foundation for subsequent operations like setting up configurations or verifying settings, which can only be done after this critical step.
