Prism Servlet
Each Niagara station includes a prism servlet, a text-based utility that provides basic troubleshooting and maintenance access. This appendix provides a brief explanation of the following prism topics:
•
About the Prism Servlet
•
Indentifying Basic Station Parameters
•
Backing Up a Station
•
Viewing External Link Data
•
Other Prism URLs
About the Prism Servlet
The prism thread (Persistent and Real-time Information Synchronization Manager) is at the heart of every station. Using prism URLs the prism servlet provides basic HTTP (browser) access to prism to review basic station configuration, verify various operations, and even perform a station backup in XML.
Prism access is universal among any Niagara host platform—the same prism URLs apply whether accessing a station in a Web Supervisor, JACE-NP, or a JACE-4 or -5.
Note
Prism-access to a station requires you to have “admin-read” rights. If you try to access a prism URL without sufficient user rights, you receive a “401 - Access Denied result.
Indentifying Basic Station Parameters
The URL for basic prism access to any running station is:
http:///prism
This produces the main prism page (Figure B, showing important configuration information about the station. In particular, the first few lines show the station’s name, Niagara release level, host name, and total number of objects (nodes).
This page is useful for troubleshooting. Access to this page, for instance, verifies that a station is running—and provides statistics on how long it has been since it was restarted
(upTime). If station issues arise, your system-support people may direct you here first.
