The OpenView Platform Adapter

The NerveCenter component that allows NerveCenter to integrate with HP OpenView Network Node Manager is known as the OpenView Platform Adapter.

For integration to take place between NerveCenter and OpenView, the following must occur:

• The NerveCenter OpenView Platform Adapter must be installed on the machine hosting OpenView.

  For detailed instructions on installing the NerveCenter OpenView Platform Adapter, see Installing NerveCenter.

• OpenView must be running.
• The NerveCenter OpenView Platform Adapter must be enabled.

  Enabling the NerveCenter OpenView Platform Adapter registers it to start as a service whenever you start OpenView. See How to Enable and Disable the Platform Adapter.

• The NerveCenter OpenView Platform Adapter must be running.

  The NerveCenter OpenView Platform Adapter typically starts at the same time OpenView starts. See How to Start and Stop the OpenView Platform Adapter.

How to Enable and Disable the Platform Adapter

A typical NerveCenter installation automatically enables the NerveCenter OpenView Platform Adapter. However, there may be times you will need to disable the NerveCenter OpenView Platform Adapter. Once you disable it, you will need to enable it manually before NerveCenter will be able to integrate with OpenView again. You can enable or disable the NerveCenter OpenView Platform Adapter by following the procedures described in this section.

Enabling the NerveCenter OpenView Platform Adapter

If the NerveCenter OpenView Platform Adapter is disabled or was never enabled during NerveCenter installation, you can enable it at any time by adding the OpenView Platform Adapter local registration file (ovpa.lrf) to the list of services that are started by ovstart.

---

   If you are unsure if the NerveCenter OpenView Platform Adapter is registered to run with ovstart, you can check OpenView's start-up file. When the NerveCenter OpenView Platform Adapter is registered, its data, including the pathname to the executable, appears in the file ovsuf typically found in the conf directory under OpenView's installation directory. If either the ovpa data does not appear or the line with the ovpa data begins with a 1, then the NerveCenter OpenView Platform Adapter will not run with ovstart.

---

 
  To enable the NerveCenter OpenView Platform Adapter:

1. From the command line of the machine hosting HP OpenView Network Node Manager, run ovstop.

   The OpenView services stop running.

   ---

      On Windows, you can also select the Services - Stop utility from the Windows Start menu.

   ---

2. Navigate to the following directory:
   • Windows: installation_path\lrf where installation_path is the installation directory for OpenView.
   • UNIX: installation_path/OV/lrf where installation_path is the installation directory for NerveCenter.
3. Run the following command:

   ovaddobj ovpa.lrf

4. Run ovstart.

   OpenView's services, including NerveCenter OpenView Platform Adapter, start running.

   ---

      On Windows, you can also select the Services > Start utility from the Windows Start menu.

   ---

The NerveCenter OpenView Platform Adapter now automatically runs every time you start OpenView.

Disabling the NerveCenter OpenView Platform Adapter

If the NerveCenter OpenView Platform Adapter is enabled, you can disable it at any time by removing the OpenView Platform Adapter local registration file (ovpa.lrf) from the list of services that are started by ovstart.

 
  To disable the NerveCenter OpenView Platform Adapter:

1. From the command line of the machine hosting HP OpenView Network Node Manager, run ovstop.

   OpenView's services stop running.

   ---

      On Windows, you can also select the Services > Stop utility from the Windows Start menu.

   ---

2. Navigate to the following directory:
   • Windows: installation_path\lrf where installation_path is the installation directory for OpenView.
   • UNIX: installation_path/OV/lrf where installation_path is the installation directory for NerveCenter.
3. Run the following command:

   ovdelobj ovpa.lrf

4. Run ovstart.

   OpenView's services, including NerveCenter OpenView Platform Adapter, start running.

   ---

      On Windows, you can also select the Services - Start utility from the Windows Start menu.

   ---

The NerveCenter OpenView Platform Adapter will no longer automatically run every time you start OpenView.

How to Start and Stop the OpenView Platform Adapter

The NerveCenter component that allows you to integrate NerveCenter with HP OpenView Network Node Manager is known as the OpenView Platform Adapter. Following a typical installation of the NerveCenter OpenView Platform Adapter component, NerveCenter enabled the OpenView Platform Adapter to run automatically as a service of OpenView.

---

   If for some reason, the NerveCenter OpenView Platform Adapter was not enabled during installation or has since been disabled, see How to Enable and Disable the Platform Adapter.

Therefore, whenever you start OpenView services by typing ovstart, the NerveCenter OpenView Platform Adapter will automatically start with any other OpenView services.

In the same way, typing ovstop stops all OpenView services, including the NerveCenter OpenView Platform Adapter.

• If you want to start only the NerveCenter OpenView Platform Adapter, you can type at the command line:

  ovstart ovpa

• If you want to stop only the NerveCenter OpenView Platform Adapter, you can type at the command line:

  ovstop ovpa
