Installing CA ERwin Data Modeler › Using a Concurrent License › Borrow a License

Borrow a License

If you use the concurrent licensing model, you can borrow licenses to use CA ERwin DM on mobile devices that support CA ERwin DM. When you borrow a license, the license rights are available on your local computer. CA ERwin DM opens using the borrowed license when you are not connected to the License Server.

You can borrow a license from the Licensing dialog at the time of opening CA ERwin DM.

Note: To borrow a Navigator license, specify the server path that has a valid CA ERwin DM Navigator license.

Follow these steps to borrow a license at the time of opening CA ERwin DM:

1. Open CA ERwin DM.

   The CA ERwin Data Modeler Licensing dialog appears.

2. Click Acquire concurrent use Workgroup Edition license or Acquire concurrent use Standard Edition license.
3. In the Server Path field, type the license server details.

   This Server Path detail is reflected in the Help, Licensing dialog.

4. Select the Return Date checkbox and specify the return date and time.
5. (Optional) Select the Remember the licensing options and do not show this dialog again checkbox.
6. Click OK.

   A license is checked out from the License Server and the rights are available on your local computer.

To return a license before it expires, start CA ERwin DM and enter the server path in the CA ERwin Data Modeler Licensing dialog. After CA ERwin DM opens, click Help, Licensing, and then click Return Borrowed Licenses Early.

Note: If a license expires or is returned before it expires, you have four hours of buffer time to save your work. After four hours of the expiry of the license, CA ERwin DM closes. Similarly, if you lose the connection to the License Server, the License Server recovers the license and CA ERwin DM closes. The recovery happens after four hours of disconnection and several warning messages.

When the license expires, one of the following events happen:

• If the client computer is connected to the License Server and a concurrent license is available, CA ERwin DM checks out a license. If no concurrent license is available, a warning dialog appears and CA ERwin DM closes after four hours.
• If the client computer is not connected to the License Server, CA ERwin DM notifies users about the loss of connectivity with the License Server.

Review the System Requirements

Review the system requirements for the computer on which you want to install CA ERwin DM.

Verify that you have installed one of the following operating systems:

• Microsoft Windows 8.1
• Microsoft Windows Vista
• Microsoft Windows Server 2008 SP2
• Microsoft Windows Server 2003 SP2
• Microsoft Windows 7
• Microsoft Windows 8
• Microsoft Windows 2012
• Microsoft Windows XP SP3: As Microsoft has dropped support for Windows XP, CA ERwin Data Modeler will no longer be tested for compatibility with that operating environment. Should you encounter any problem(s) using CA ERwin Data Modeler you should first verify that the problem(s) encountered are not related to an unsupported operating environment before reporting the problem(s) to CA.

  Note: CA ERwin Data Modeler is a 32-bit application and is fully compatible with 64-bit operating systems, except for the following known issues:

  • 64-bit database drivers and clients will not work with the application. The workaround is to use 32-bit database drivers and clients in the 64-bit operating system environment.
  • Running the CA ERwin API in a 64-bit environment requires some changes to the workstation registry. For more information about changing the registry, see the CA ERwin Data Modeler WE Implementation and Administration Guide.

The following requirements must be met or exceeded for CA ERwin Data Modeler to install and run correctly:

• Microsoft-based workstation, Intel Dual Core processor or equivalent
• 2 GB available hard drive space
• 2 GB RAM minimum; more is recommended for large models
• DVD-readable device (only if installing from DVD media)

Note: The minimum screen resolution supported is 1024 x 768. If your screen resolution is less than the minimum supported, some portions of the screen will not be visible.
