Overview

QESTField Scheduler is a React.js front-end + ASP.NET back-end web application, which is hosted via Internet Information Services (IIS). A connection to an instance of the QESTNet service is required, through which it can operate on the QEST Platform database.

Prerequisites

The following must be present in the target environment to support QESTField Scheduler.

Machine

• Google Chrome (or other Webkit-based web browser)
• Windows Server 2008 R2, Windows 7 or later (64-bit).
• Microsoft .NET Framework 4.6.2 or later. If required, this will be installed via the QESTNet installer if the environment has internet access.
• Internet Information Services 7.0 or later with default features plus ASP.NET v4.5.
• QESTField v4.6.

Services

• QESTNet v4.6 with the QESTLab API for QESTNet installed (default), accessible via TCP or HTTP.

Installation Files

• Installer QESTFieldScheduler.Installer.Ma.Mi.B.R.exe where Ma, Mi, B and R are the major version, minor version, build and revision numbers. E.g. QESTFieldScheduler.Installer.4.6.2895.26827.exe

Installing QESTField Scheduler

1. Run the provided installer.

2. If required, click on Options to change the installation options listed in the section below.

3. Agree to the terms and conditions and click Install. The installer will install and turn on any required Windows features before installing QESTField Scheduler.

Installation Options

Configuring QESTField Scheduler

1. If required, open the Web.config file which was installed into the QESTField Scheduler folder with a text editor. At the bottom of the file change all client endpoint address host names from localhost to the name or IP of the QESTNet server to which QESTField Scheduler will be connecting. Close and save the file. If any other configuration changes were made to the QESTNet such as port or protocol then the same changes must be made here.

     <system.serviceModel>
       <bindings>
         ...
       </bindings>
       <client>
         <endpoint address="net.tcp://localhost:52525/Lab" binding="netTcpBinding" bindingConfiguration="Lab_Session" contract="Spectra.QESTNET.Contracts.ISessionService" name="Lab_Session" />
         <endpoint address="net.tcp://localhost:52525/Lab/query" binding="netTcpBinding" bindingConfiguration="Lab_Query" contract="Spectra.QESTLab.Contracts.ILabQueryService" name="Lab_Query" />
         <endpoint address="net.tcp://localhost:52525/Lab/file" binding="netTcpBinding" bindingConfiguration="Lab_File" contract="Spectra.QESTLab.Contracts.ILabFileService" name="Lab_File" />
       </client>
     </system.serviceModel>

2. Depending on the installation options used, the QEST Platform website and QESTField Scheduler application may need to be manually configured and/or started via the IIS Manager. Note if you are manually configuring the QESTField Scheduler application, it must be configured with alias "Scheduler".

QESTField Scheduler is now installed and ready for use. If you navigate to the URL where QESTField Scheduler is hosted, you should see the login screen.

Troubleshooting guide

Installation

Unspecified Error

If you get the following installation error ‘0x80072ee7 – Unspecified Error’, this is most likely due to the installer being unable to download and install .NET Framework 4.6.2.

You can confirm that this is the issue by viewing the log file and looking for the following: Failed attempt to download URL: 'http://go.microsoft.com/fwlink/?LinkId=671728' to: 'C:\Windows\Temp{B321459C-617D-4C9F-8C70-15AEEE5945CF}\NetFx462Web'

Fix: To install QESTField Scheduler you will need to download .NET Framework 4.6.2 and install it prior to installing QESTField Scheduler. The .NET Framework 4.6.2 Installer can be found here: https://www.microsoft.com/en-au/download/details.aspx?id=53344

         ...
       </bindings>
       <client>
         <endpoint address="net.tcp://localhost:52525/Lab" binding="netTcpBinding" bindingConfiguration="Lab_Session" contract="Spectra.QESTNET.Contracts.ISessionService" name="Lab_Session" />
         <endpoint address="net.tcp://localhost:52525/Lab/query" binding="netTcpBinding" bindingConfiguration="Lab_Query" contract="Spectra.QESTLab.Contracts.ILabQueryService" name="Lab_Query" />
         <endpoint address="net.tcp://localhost:52525/Lab/file" binding="netTcpBinding" bindingConfiguration="Lab_File" contract="Spectra.QESTLab.Contracts.ILabFileService" name="Lab_File" />
       </client>
