Deploying the Watson Query Remote Agent on Windows

Deploy the Watson Query Remote Agent on Windows.

1. Download and install the Java Runtime Environment from IBM® SDK, Java Technology Edition, Version 8 from Java SDK downloads, version 8.0 or the appropriate version of Oracle Java SE 8. Take a note of the installation path to complete the next steps.
2. Download the IBM Watson Query Remote Agent .zip file from IBM Watson Query Remote Agent.
   1. Unblock the Remote Agent archive by right clicking the .zip file, and then selecting Properties > General > Unblock.
   2. Extract the archive and take a note of the installation path. For example: C:\Users\Administrator\WATSON_QUERY_REMOTE_AGENT_V2.1.3
      Note: Ensure that the user who runs the remote agent has Read, Write, and Execute permissions on the directory.
3. Open a text editor, and then create a new document with the following information. Enter the remote agent installation path and the Java installation directory.

   set DATAVIRTUALIZATION_INSTALL="<Remote agent installation path>" 
   set JAVA_HOME="<Java installation directory>"

   For example:

   set DATAVIRTUALIZATION_INSTALL="C:\Users\Administrator\WATSON_QUERY_REMOTE_AGENT_V2.1.3" 
   set JAVA_HOME="C:\Program Files\IBM\Java80\jre"

4. Optional: To add memory or Kerberos configuration, complete the following tasks.
   • To change the memory from the default of 256 Mb to 512 Mb, add the following line to the file:

     set JAVA_OPTS=-Xmx512m

   • To allow the remote agent to access a Kerberos enabled data source, find the path to the krb5.ini file and then add the following line to the file. Enter the path to the krb5.ini file.

     set KRB5_CONF_FILE=<File path to the krb5.ini>

     For example:

     set KRB5_CONF_FILE=C:\ProgramData\MIT\Kerberos5\krb5.ini

   When you are done configuring the file, save it as a plain text file in the installation directory you created and name it as datavirtualization.env.bat.

   Windows service uses this file when you start the agent.

5. Open the Windows Command Prompt App.
6. Run the following command to change to the agent installation directory and to configure the agent. Enter the value for each parameter as described in the following table.

   cd <Remote agent installation path> config.bat -i "<Instance ID>" -c "<Configuration Hash>"

   For example:

   cd C:\Users\Administrator\WATSON_QUERY_REMOTE_AGENT_V2.1.3 config.bat -i "pre6e3c0-f94c-4f83-96bd-1004fbeff381" -c "Tm2IdX1tf20..."

   Table 1. Parameters and parameter descriptions that you use to deploy the Remote Agent on Windows

   Parameter	Description
   Remote Agent installation path	Enter the installation path for the Remote Agent.
   Instance ID	Enter the Instance ID from the Output values column. See Generating the configuration for the Watson Query Remote Agent.
   Configuration Hash	Enter the Configuration Hash from the Output values column. See Generating the configuration for the Watson Query Remote Agent.

7. Install the Windows service to automatically start the Watson Query Remote Agent when the system starts.
8. Run the following command from the command prompt window to install Watson Query on the Windows system. Enter the port number that the Remote Agent service is configured to use, as well as the Administrator password.

   install_dv_service.bat -p <Port number> -s <User password>

   For example:

   install_dv_service.bat -p 6414 -s abc123

9. After you install the Windows service, exit the command prompt and return to the Watson Query web client.
10. Navigate to the Data Sources tab and select Reload Connections to view the Remote Agent.
    After you deploy the Remote Agent, proceed to start the agent manually for immediate use or configure it as a system service to start automatically.

    To manually start the agent, see Manually starting the Remote Agent on Linux.

    To automatically start the agent, see Automatically start the Remote Agent by adding a systemctl service on Linux.
