Licensing 

A brief overview of the licensing requirements for Allegro® X and OrCAD® X products. 

• Configuring and Using the License Manager 

Configuring and Using the License Manager

Although the installer installs and configures the license server, you can configure the server at any time using the License Client Configuration Utility. The license path to an existing license server is in the form of <port_number>@<host_name>, such as 5280@corporatelicenseserver. 

You can specify and get the license path information from the Cadence license file. The license path is specified in the license file by the SERVER keyword in the following form: 

SERVER <host_name> <license text> <port_number> 

For example, in the line SERVER corporatelicenseserver 83065c2 5280, corporatelicenseserver is the host name and 5280 is the port number. 

Types of License Manager 

Two types of installations are possible for the license manager: 

• Standalone Installation 
• Network Installation

Standalone Installation 

To install the licensing for a single user on an isolated computer that will not depend on access to a network, install the License Manager directly on that computer. 

Network Installation 

In a network installation, you install the License Manager on a computer that is accessible over a network, referred to as a license server. In this configuration, multiple users can run the Cadence products at the same time across the network by accessing the license and file server. 

You may have up to three license servers running simultaneously. These are referred to as redundant license servers. The licensing system remains operational as long as any two of the three License Managers are functioning properly. 

Uninstalling the License Manager 

To uninstall the License Manager 

1. Open Programs – Programs and Features from the Control Panel of Windows.
2. Navigate to Cadence License Manager and click Uninstall.

The License Server Configuration Utility 

The License Server Configuration Utility (Start – Cadence – License Manager – License Server Configuration Utility) lets you configure licensing on a license server without having to reinstall the License Manager. 

Use the License Server Configuration utility for the following conditions: 

• You received a replacement license file from Cadence. 
  You will receive a replacement file in the following conditions:
  • Current license file is about to expire.
  • You purchased additional licenses for products that you have already installed.
• You received a new license file from Cadence.

To Use the License Server Configuration Utility 

1. From the Start menu, choose Cadence – License Manager – License Server Configuration Utility. 
   The License File Location dialog box appears.
2. Specify the location of the Cadence license file or browse to it, and then click Next 
   The License Server Data dialog box appears. 
3. Review the license server information and modify the host name if necessary and click Next. 
   The Restart License Server dialog box appears informing you that the license server is running and will restart. 
4. Click Next. 
   The Configuration Status dialog box appears. 
5. Click Finish to exit the License Server Configuration utility. 
   Configuring the license file is complete. 

The License Client Configuration Utility 

Use the License Client Configuration Utility (Start – Cadence – License Manager – License Client Configuration Utility) to change the CDS_LIC_FILE variable to point to a different or an additional license server. After remote client product installations, either interactive or unattended, you must use the License Client Configuration Utility to set up the client machine to find the license server. 

To Use the License Client Configuration Utility 

1. From the Start menu, choose Cadence – License Manager – License Client Configuration Utility. 
   The License Path dialog box appears. Specify the port and hostname of the license server(s) you want to use, and then click Next.
   You can use semicolon (;) to specify multiple license servers, such as port1@host1;port1@host2. You can also specify a fault tolerant or triad license server. Use the comma to separate the triad hosts, such as port1@host1,port1@host2,port1@host3. 
   You can get the license path information from the Cadence license file. The license path is specified by the SERVER keyword in the following form: 
2. SERVER <host_name> <license text> <port_number> 
3. For example, in the line SERVER corporatelicenseserver 83065c2 5280, corporatelicenseserver is the host name and 5280 is the port number. 
   The Configuration Status dialog box appears to confirm that the CDS_LIC_FILE variable is updated.
4. Click Finish to exit the License Client Configuration utility.
