Reviewing/adjusting PlatformServices properties for the JACE

Prerequisites:

A station in the JACE is running, and that station opened in Workbench.

In the Nav tree, double-click Services and then PlatformServices.

Its “Platform Service Container Plugin” displays in the view pane.

Some properties are read-only status types, similar to many seen in the Platform Administration view. Other configuration properties can be edited. A group of 3 config properties allow adjustment of the time, date, and time zone settings for the host JACE (alternately accessible using a platform connection to the JACE). Access to these properties is useful if the installation requires all setup access using a browser only.
As needed, review other platform service configuration properties, which include the following:
NOTE: You should leave the following properties at default values, unless otherwise directed by Systems Engineering.
- Locale — Determines locale-specific behavior such as date and time formatting, and also which lexicons are used. A string entered must use the form: language [“_” country [“_” variant]]
  For example U.S. English is “en_US” and traditional Spanish would be “es_ES_Traditional”.
  
  See Oracle documentation at http://docs.oracle.com/javase/1.4.2/docs/api/java/util/Locale.html for related details.
- Engine Watchdog Policy — Defines response taken by the platform daemon if it detects a station engine watchdog timeout. With the watchdog, the station periodically reports to the platform daemon its updated engine cycle count. The watchdog purpose is to detect and deal with a “hung” or “stalled” station, and is automatically enabled when the station starts.
  Watchdog policy selections include:
  
  Log Only — Generates stack dump and logs an error message in the system log. (The station should ultimately be restarted if a watchdog timeout occurs with the “Log Only” setting).
  
  Terminate — (Default) Kills the VM process. If “restart on failure” is enabled for the station (typical), the station is restarted.
  
  Reboot — Automatically reboots the host JACE platform. If “auto-start” is enabled for the station, the station is restarted after the system reboots.
- Engine Watchdog Timeout — Default is 3 minutes in Niagara 4, and range is from 1 minute to many hours.
  If the station’s engine cycle count stops changing and/or the station does not report a cycle count to the platform daemon within this defined period, the platform daemon causes the VM to generate a stack dump for diagnostic purposes, then takes the action defined by the Engine Watchdog Policy.
- Enable Station Auto-Save — Either Enable (default) or Disable.
  Allows for “auto save” of running station to “config_backup_<YYMMDD>_<HHMM>.bog” file at the frequency defined in next property. Auto-saved backup files are kept under that station’s folder.
- Station Auto-Save Frequency — Default is every 24 hours for any embedded JACE, range is from 1 to many hours.
- Station Auto-Save Versions to Keep — Default is 0. Oldest of kept backups is replaced upon next manual save or auto-save backup, once the specified limit is reached. Significant flash space is saved by keeping this 0 or perhaps 1.
- RAM Disk — In MB (default is 1GB). Indicates the size of RAM disk used to store history and alarm files.
  
  Min Free — sets the level at which Platform Services and Platform Admin show a warning.
For further details on these and other PlatformServices properties, refer to the “PlatformServiceContainer parameters” section in the Niagara Platform Guide.
