Monitor Redundancy Status (Batch Management with Foxboro DCS Components)

The status of a redundant system is made available to your Foxboro DCS network by way of a shared variable. The shared variable can be used to monitor the redundancy status of the server. In operation, FoxDCSDriver continuously attempts to write an integer value to the shared variable. If the write attempt fails, a message is displayed and the feature is disabled.

The format of the shared variable is: <hostname>_RS

where: <hostname> is a machine name and _RS is appended to the

<hostname>

(for example, AW5104_RS)

Create the Shared Variable

Create the redundancy share variable file and make it executable. In the /opt/fox/bin/tools directory, execute the following command:

omcrt -v -i AW5104_RS

The shared variable that you created above is discarded each time you reboot your system. If you want to create this shared variable automatically each time you restart the system, there are two recommended options. The first is to edit the init.user file located in /usr/fox/wp/data and define the shared variable following the format and instructions in the file. The second is to include the omcrt command above in a batch start-up script identified in the /usr/fox/bin/fox_apps.dat file.
