Icon
The following is applicable only for ExamDeveloper version 7.1610.0.0 and above.

 

This page describes the following:

  1. Configure the ExamService Service
  2. Installation of ExamService Windows service
    1. Install the ExamService
    2. Start the ExamService

Configure the ExamService Service

Icon

It is important to ensure that all the values in the config files such as service name, URLs, username, and password are case-sensitive. ExamDeveloper may not run as expected if care is not taken to ensure that case sensitivity is maintained.

  1. Create a folder where you want to install ExamService, such as C:\EDEXS\ExamDeveloper\ (henceforth known as <EDEXSinstallDir>) and copy all the contents of <SVNFolder>\Exam\ (or <SVNFolder>\ExamService\) to this folder. In case of ExamDeveloper version 7.1610, the <SVNFolder>\ExamService\ folder contains a ZIP file ExamService.zip, please extract it to <EDEXSinstallDir> while ensuring that the folder structure within the archive is recreated.
     

  2. Open the various configuration files for ExamService located in C:\EDEXS\ExamDeveloper\configs (<EDEXSinstallDir>\configs\) - appSettings.config, connectionStrings.config, and log4net.config - with Notepad or a suitable text file editor.
     

  3. In the appSettings.config, enter a unique name and unique display name for the ExamService service, which is to be created and run on the application server.


    where,
    UniqueExamServiceName and UniqueExamServiceDisplayName are the unique name and display name given to the ExamService service. These names needs to be unique per install and should not contain any space.

  4. In the appSettings.config, ensure that the values of the keys "basicAuthUserName" and "basicAuthPassword" match the values in ExamDeveloper httpClients.config of the keys "userName" and "password" respectively for the line with httpClientConfig name "ExamSection" as in step 11 of Configure ExamDeveloper.

  5. If a line with the key "useSsl" exists, set the value to "true" as follows:

  6. If a line with the key "relativeUri" exists, set the value to "UniqueExamServiceName" as follows:


    where UniqueExamServiceName is the name the ExamService service.

     

  7. In the connectionStrings.config, update connection string value to match the value from the EDRS connectionStrings.config file as in step 2.a of EDRS Installation and Configuration.

    Icon

    Step 8 is applicable only for ExamDeveloper version 7.1612 and above.

  8. In the massTransit.config file, update the values to match the corresponding values from massTransit.config of EDRS as detailed in step 2.c of EDRS Installation and Configuration. This means that the name of the Virtual Host ExamDeveloper created in Create and configure RabbitMQ Virtual Host section of the RabbitMQ Setup and Configuration page, should be appended to the massTransit/host/rabbit@hostAddress attribute, which is rabbitmq://localhost/ExamDeveloper in our example. The username and password must match the RabbitMQ user (having access to the Virtual Host ExamDeveloper), created in the Create a RabbitMQ user for EDRS section of the RabbitMQ Setup and Configuration page, which in our example are ExamDeveloper and Password respectively.

    Icon
    If RabbitMQ is installed on a separate server, then you must substitute "localhost" with the hostname of that server. If RabbitMQ-URL is the server hostname where RabbitMQ is installed, then the line becomes:

    <rabbit hostAddress="rabbitmq://RabbitMQ-URL/ExamDeveloper" username="ExamDeveloper" password="Password"/>
    Icon

    It is extremely important that the same RabbitMQ Virtual Host name should not be shared between different instances of ExamDeveloper, as this can result in issues such as data loss and security breach.

    It is important to ensure that the RabbitMQ Virtual Host name, username, and password are case-sensitive. You will encounter an error while trying to log into ExamDeveloper if care is not taken to ensure that both are specified exactly as they are in the new RabbitMQ Virtual Host and user setup for this instance of the ExamDeveloper application.

     

     

  9. Update the values in the <log4net> section of the log4net.config file as shown below to indicate the path where the log file for ExamService service is to be located.


    By default, the log file ExamService.log is saved to the User service folder (C:\EDEXS\ExamDeveloper\ in our example). You can specify a different path to save it by modifying the value to something like "C:\ExamDeveloperData\Logs\ExamService\ExamService.log" as shown above.

Installation of ExamService Windows service

Install the ExamService Service

  1. Open an Administrator command prompt and run the following command:
     
    netsh http add urlacl url=https://+:443/UniqueExamServiceName user=Everyone

    where UniqueExamServiceName is the name of the ExamService service.

     

    Icon

    If you get an error stating "Url reservation add failed" on running the above command, please ignore it as it means that this has already been taken care of.

     

     

  2. Open an Administrator command prompt (click the Start button, type "command" in the search box, right click Command Prompt in the search results that appear, and click Run as administrator from the context menu) and navigate to <EDEXSinstallDir>.

  3. Run the following command:

    ExamService
