Appendix B Prism Servlet Backing Up a Station Niagara Release Niagara Browser Access Guide Revised: August 15, 2002 B–3 Backing Up a Station Another prism function is the ability to download a station’s database directly in your XML-capable browser (such as Internet Explorer xor higher, or Netscape Communicator 4.7 or higher. Once downloaded, the database can be saved on your PC as an .xml file for possible restoration later—or perhaps just for examination. The prism URL to backup a station’s database (in XML) is: http:///prism/backup Although not recommended for routine backups, which are done more efficiently using the JDE, it remains an option. Be aware that fora large station database, this backup (download) process can take along time to complete—an hour or more. If a Web Supervisor or JACE-NP station, the following URL causes the station backup to be stored locally (on the remote JACE-NP or Web Supervisor PC): http:///prism/backupLocal Progress is displayed by the exported listing of all Swids in the station, in text format. Caution A backupLocal replaces any existing station database (in .xml format) on the remote host. Before entering this URL, please get approval from your system administrator. P RISM XML A CCESS Related to this, prism is also capable of downloading the XML-formatted portion of the database for any single object, given its proper station Swid in this URL: http:///prism/xml/ For example http://192.168.1.131/prism/xml/demoR2/Sim/Displays/Home downloads in XML from station “demoR2” the database portion for the GxPage object Home which resides in the Swid shown above. Viewing External Link Data The prism servlet includes a URL that lets you seethe status of external links—that is, inter-station links (between stations. Most systems with a Web Supervisor, for instance, have many external links between the Web Supervisor station and JACE stations. Each external link is characterized by its two halves a subscription or receiving side, and a publication or sending side. The URL for viewing status of external links is: http:///prism/externalLinks This produces a snapshot of all external links in process by the station (Figure B-2 ).
