What causes the following error when I start the console?
$ ./start_console.sh
$ Exception in thread "main" java.lang.NoClassDefFoundError:
com/cisco/gdpm/console/view/ConsoleMainFrame
The classpath is not set up properly. This might be caused by one of the following reasons:
You chose not to copy (append or replace) the profile during installation.
If you copied the profile, you did not log out and log back in to get the new profile.
You are not using ksh as the default shell.
What is the format of the batch import file?
Refer to Batch Import File Sample.
How do I import a file?
You can import a batch file from the console or the VRC client.
From the console, click the Operations tab, and choose Batch Import Network Element. Refer to Topology Operations for more information.
From the client, choose Import Topology from the Topology menu.
When you import files from the client, the batch import file must be located in the /tftpboot/gdpm/batch/ directory.
Why do I receive the following error on my browser when I try to launch the VRC client?
No Java 2 SDK, Standard Edition v 1.3 support for APPLET!!
You are probably using an unsupported browser. VRC supports only Internet Explorer 5.0 or 5.5.
Why do I receive a “The page cannot be displayed” error on my browser when I try to launch the VRC client?
You might not be using a trailing “/” after VRC in the address. Make sure the address is:
http://<server name or IP address>:8080/VRC/
Can I populate the topology with only part of my configuration and execute a Discovery using just this part until I become familiar with VRC?
We recommend that you do not execute a Discovery on a partial configuration. This might cause errors in the Discovery process. If you have elements in the topology that have dial plan references to elements that are not in the topology, VRC might not be able to resolve the references.
How do I execute a Discovery?
From the Baseline View, right-click the Administrative Domain (AD) or region and choose Discover from the menu.
We recommend that your initial Discovery be done at the AD level.
What is the difference between normal and forced Discovery?
A normal Discovery stops if an element is unreachable or if a network element is defined incorrectly in the topology (for example, a gateway is really a gatekeeper). Refer to About the Discovery Process for more details on what causes the normal Discovery process to stop.
A forced Discovery logs all errors and moves on to Discover the next network element.
When I open a saved design file, is it true that I may be out of sync with the Baseline?
Yes. Another user might have changed the baseline dial plan since you last started and saved your dial plan design.
How do I receive more debugging information than what is provided in the user log on the client?
Access the VRC console and turn on debugging. You can choose to debug a single process or debug all processes. If you are unsure of which process to debug, choose debug all. Refer to Set Debugging On or Off for more information.
On the server, debugging information is logged in the /opt/vnm/gdpm/log/gdpminternal.log directory.
I enabled debugging through the console and it was logging correctly. However, after the server was restarted, debugging is no longer turned on.
When you enable debugging from the console, it is only persistent until the VRC software is restarted, at which time the default setting of disabled is reinstated.
Why do the installation scripts and directories use the name gdpm instead of vrc?
The Cisco Voice Routing Center (VRC) was previously named GDPM. The directory structure and installation scripts were not changed to reflect the new product name.
