FAQ for Licensing

These questions are asked frequently about your licensing environment.

What is a license file and what do I do with it?

The license file is a text file that contains the following:

  • Product licensing information
  • License server name (or other binding identifier)
  • Customer Success Services membership renewal date
  • License expiration date (if applicable)
  • Other system information

When you purchase a Citrix product, you are entitled to a license file. The License Server uses this file to determine whether to grant a license to a Citrix product.

What does allocating licenses mean?

When you allocate licenses, you apportion purchased licenses by product and License Server so you can split them among multiple environments or use cases. For example, your organization might own 1,000 licenses for the same product. You might want to use 800 in 1 location and 200 in another location. You can allocate 800 licenses to a license server in the first location today, and allocate the remaining 200 later to a different license server.

What’s the difference between Host ID type and Host ID?

The Host ID type is the required binding type you supply to allocate licenses. The Host ID is the license server host name, MAC address, or other binding ID required to allocate licenses.

Why can’t I partially allocate some licenses?

Some licenses do not allow partial allocation.

Why would I return a license?

An example would be if you’re decommissioning a License Server, but you’re not ready to deploy existing licenses elsewhere.

What happens to returned licenses?

Returned licenses are put back in the licensing pool. These licenses can then be allocated in any quantity at any time. After you return a license, remove the old license file from the License Server.

What happens when I archive a license?

Archiving doesn’t remove licenses from an account. Archiving removes them from view. To view archived licenses, click the Archive tab under View Licenses.

Can I rename the License Server?

License files run only on the License Server for which they were made. License files contain the host name or binding identifier of the license server you specify when you allocate the licenses. You cannot use the license file that you generated for a particular License Server or a MAC address (for an appliance), on a different License Server or appliance.

Create license files that reference the new server name or MAC address by reallocating and generating the new file on citrix.com.

If I upgrade my License Server does it affect my license files?

No. The License Server and all product licenses are fully backward compatible and do not introduce any issues into your environment.

Can a single License Server supply licenses to users connecting from different servers using different product editions?

Yes. One License Server can contain licenses for multiple editions of a Citrix product. The type of license checked out corresponds to the edition that is configured on the product server. A product server is configured to consume a specific edition of a license and checks out that license edition.

For example:

ProductServerA is configured to check out Enterprise licenses.

ProductServerB is configured to check out Platinum licenses.

LicenseServer1 contains both Enterprise and Platinum licenses.

  • Users who connect to LicenseServer1 from ProductServerA check out Enterprise licenses only. After the number of Enterprise licenses on LicenseServer1 is exceeded, new requests from ProductServerA users are denied until existing Enterprise connection licenses are released.
  • Users who connect to LicenseServer1 from ProductServerB check out Platinum licenses only. If the number of Platinum licenses on LicenseServer1 is exceeded, new requests from ProductServerB users are denied until Platinum connection licenses are released.

Note

License checkout times might increase if many product servers that have many users are contacting the same License Server simultaneously. One License Server can accept only 10,000 inbound TCP/IP requests at one time. If you are planning to have more than 10,000 Citrix product servers connecting at the same time, we recommend that you use several License Servers. These product servers can include XenApp, XenDesktop, Delivery Controllers, and Appliances.

Examples of possible deployments:

Scenario 1: Two farms

  • FarmA contains product servers configured for Enterprise edition.
  • FarmB contains product servers configured for Platinum edition.
  • One license server (shared).
  • User1, User2, User3, User4…User5000 connect only to FarmA.
  • User5001, User5002, User5003…User10000 connect only to FarmB.

Scenario 2: One farm

  • The farm has two sets of published applications.
  • Product servers configured for Enterprise edition host one set of applications.
  • Product servers configured for Platinum edition host one set of applications.
  • One License Server (shared).
  • User1, User2, User3, User4…User5000 connect only to product servers that have the first set of applications.
  • User5001, User5002, User5003…User10000 connect only to product servers that have the second set of applications.
