TKE - DDE Server Fail-Over Process.

Overview

This document covers how to fail-over the BluB0X DDE Remote Servers.

TKE - DDE Servers Failover Process.

This process consist of two steps.

Step 1 - Disables services on primary DDE server.
Step 2 - Enables these services on backup server. You will be required to physically switch network cable from Primary server on to Back up server in order for failover to be successful.

Note:

System Downtime is under an hour.
Requires presence on site to switch cables (1 Person)
Make sure you inform your customer that DDE system will remain open/unsecured until failover process is complete.

Locate both DDE servers. Normally labeled as DDS 1 and DDS 2. If both servers are not clearly labeled, we strongly encourage you to label them before moving forward.
Find out which server is a primary one. It should have two Ethernet cables connected to it, one in the back and second one to the front. If cable are not labeled please label them accordingly.
Log-in into the current primary server. Open Services, and locate BluB0x_TKE Interface service. First STOP the service. Then right click go to properties, and DISABLE this service.
Open Notepad as an administrator.
- Open File by browsing to C:\Program Files (x86)\BluB0x\BluB0x_LocalSync\Blub0x_LocalSync.exe.config file. (While browsing to a file switch the file type for "All File Types” in order to see this file)
- Change two settings: (setting are highlighted in red)
  <add key="PollingPeriod_sec" value="60"/> TO <add key="PollingPeriod_sec" value="120"/>
  <add key="ServiceBusTopicPrefix" value="" /> TO <add key="ServiceBusTopicPrefix" value="dev_" />
Save and close that file.
Open Services again, locate BluB0x_LocalSync service and restart the service.
At this point you have stopped all services on primary DDS server which are responsible for operation DDE system. All floors should be open at this point.
Unplug TKE side Ethernet cable from the current primary server and plug it into the TKE side of the backup server.

Login to Back Server
- Open Notepad as an administrator. Open a C:\Program Files (x86)\BluB0x\BluB0x_LocalSync\Blub0x_LocalSync.exe.config file. (While browsing to a file switch the file type for "All File Types” in order to see this file)
- Change two settings:
  <add key="PollingPeriod_sec" value="120"/> TO <add key="PollingPeriod_sec" value="60"/>
  <add key="ServiceBusTopicPrefix" value="dev_" /> TO <add key="ServiceBusTopicPrefix" value="" />
- Save and close that file.
Open Services again,
- Locate BluB0x_LocalSync service and restart the service.
- Locate BluB0X_TKE Interface service,
  - Right click and set it to AUTOMATIC mode.
  - Click Apply and OK.
  - Manually START this service. (BluB0X_TKE Interface)
Now this server is the primary and the other is a backup server.
Test the operations of the system by swiping a valid card at every turnstile and kiosk. Make sure proper floor is given and car is assigned.
Create a visitor card to BluSKY and verify that it is working at the correct turnstile and kiosk.
