Preparing the Operating System for GVP

This topic describes how to prepare the Windows operating system for Genesys Voice Platform (GVP) 8.5.x deployments. For information about the software prerequisites when deploying GVP on the Windows platform, see Prerequisites.

Tip
  • There are no requirements to prepare the Linux platform for GVP. This section contains information about the Windows platform only.
  • GVP supports installation on virtual machines created by VMware ESXi5 software. All the same requirements for physical GVP host systems apply. See the VMWare ESXi5 manuals and the operating system vendor documentation for installing virtual machines.

Windows Services and Settings

Complete the tasks to configure Windows services and modify Registry settings on each host before you install GVP. See the Task Summary below.

Important
When you name a computer, do not use the underscore (_) character, even though Windows setup permits it. Using the underscore character causes serious problems with several web services used by the GVP software.

Objective Related Procedures and Actions
Note: All instructions apply to both Windows 2008 and Windows 2012.
1. Modify Windows Registry settings. Accommodate environments that handle a large number of concurrent calls or enable quick usage of MRCPv2 ASR & TTS resources by changing the following Windows Registry parameter on all GVP hosts before you begin the deployment.

If you have planned your environment to reach call volumes of more than 200 concurrent calls, use the regedit.exe command to add the DWORD parameter to the following registry key:
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/tcpip/Parameters

  1. Select Edit > New.
  2. Click the DWORD value, enter TcpTimedWaitDelay with decimal value: 30 (or hex value: 1e)
  3. Exit the Registry and reboot the computer.

The minimum value for this parameter is 30 seconds. DWORD resets any value less than 30 to the default of 240 seconds.

2. Modify Windows OS settings. Set the IP DiffServ bits on outgoing packets by defining the QoS Policy in the QoS Packet Scheduler, which is included in the OS.

For instruction about how to define the IP DiffServ bits on outgoing packets per executable or per port, see the article, Creating and Editing the QoS Policy in the Tech Center Library on the Microsoft website.

  • Changing the QoS policy is optional; do not do it casually.
  • If you are installing the PSTN Connector and Dialogic, disable Physical Address Extensions (PAE) by executing the following commands in the CLC: C:\bcdedit /set nx OptOut
    C:\bcdedit /set pae ForceDisable
    Then, restart the server.
3. Enable or disable the required services, and set service start modes. Modify the following services as indicated:
  • Internet Information Server (IIS) Admin Service: AutomaticA
  • World Wide Web Publishing Service: AutomaticB
4. Specify the recommended system performance settings. See Procedure: Configuring Settings for System Performance below.

Note: See also the MicroSoft web page "Configuring Policy-based Quality of Service (QoS)," here: https://technet.microsoft.com/en-us/library/hh831689.aspx.

A: Not required for the default setup of MCP component. If you require inline grammars on the MCP, then consult Microsoft documentation on how to add the appropriate roles and features in Windows 2008/2012 to enable the Internet Information Services (IIS). Also, refer to the GVP 8.5 User's Guide or the Voice Platform Media Control Platform Configuration Options for how to configure inline grammars.
B: Inline grammars, when enabled, must be hosted on the local web server (MCP only). Please refer to the Microsoft documentation on how to add the appropriate roles and features in Windows 2008/2012 to enable the World Wide Web Publishing Service. Also, refer to the GVP 8.5 User's Guide or the Voice Platform Media Control Platform Configuration Options for how to configure inline grammars.

Procedure: Configuring Settings for System Performance

Complete this procedure for each Windows server that will host GVP components, to maximize host performance.

  1. Go to the Control Panel >System> Advanced tab.
  2. In the Performance section, click Settings.
    The Performance Options page appears.
  3. Select the Advanced tab.
  4. In the Processor scheduling section, select Background services.
  5. Set the virtual memory size:
    1. In the Virtual memory section, select Change.
      The Virtual Memory page appears.
    2. Select Custom size and then set the following:
      • Initial size (MB): 1.5 times your RAM
      • Maximum size (MB): 2 times your RAM
    3. Select Set.
  6. Click OK to exit all dialog boxes.
  7. When prompted, restart the computer.
