Add the IP address variable

If you are deploying an HA DCE infrastructure on servers that are also running DRE, additional configuration is required to correct certain undesired network behavior. For standalone DCE servers without DRE running on them, the following IP Address configuration in not required.

If the secondary loopback NIC containing the IP Address of the VIP (for HA DCE) is added to a server that is also running DRE, when a user prints the DRE sends both IP Addresses to CAS. When there are multiple registrations with the same IP Address, users do not see jobs that have been printed to different DREs. For example, if a user prints a job to DRE1, and then another job to DRE2, they only see the job on DRE1. This happens because both DREs have registered the same IP Address (the VIP assigned to the loopback adapter), and it is assumed that since DRE1 has been queried for jobs, DRE2 has also been queried.

In order to correct this behavior, and have DCE only send its production IP Address as part of the service registration message, a system environment variable must be added to each DRE/DCE containing the appropriate IP Address.

  1. Go to Control Panel > All Control Panel Items > System Access on the DRE/DCE, and select Advanced system settings.
  2. On the System properties window, click Environmental Variables.
  3. On the Environment Variables window, click New from the System variables section.
  4. Create the Variable name EQ_IPADDRESSES with a Variable value of the production IP Address of your Equitrac DRE/DCE server, and press OK and then OK again.
  5. Repeat these steps above for every DRE/DCE in your deployment.
