# Redundant License with Commuter Option

A commuter license enables you to “check out” an authorization for a license for temporary use on a portable computer. The redundant licenses can also be commuted. Your vendor selects whether a network license code will be a commuter license when creating the license code. However, the following points must be noted:

- A redundant license can be commuted in two ways:
- Directly obtaining a commuter license
  To directly check out an authorization, the portable computer (for example, a laptop) on which the application is to be used must be attached to the network and have access to a License Manager containing licenses for that application. The application must also be installed on that laptop. After checking out an authorization, you may disconnect the laptop from the network.

- Remotely obtaining a commuter license
  A license can also be checked out for a computer that does not have direct access to the License Manager. In such a case, any computer that can access the License Manager can check out the license for a remote computer by using remote checkout. For more details, refer to the Sentinel RMS System Administrator’s Help.

- The licenses can be checked out only from the primary License Manager.
- The commuted license must be checked in back into the primary License Manager from which it was checked out.
- If the primary License Manager goes down, the information about already checked out tokens is not transferred to the new leader.
- If any secondary License Manager recovers before the primary License Manager, check in of the commuted license fails on the primary License Manager,
- The WCommute utility might not show the proper check-out status of a license token if the License Manager name set in the specific License Manager field is other than the primary License Manager. Such a scenario might appear when the primary License Manager is not up and the user is trying to obtain the check out status of a license token from any secondary License Manager.

Because commuter licenses may automatically expire after the specified number of days (except for unlimited check-out of a non-expiry licenses), there is no real reason to check in the authorization back in unless the redundant License Manager pool is running low on commuter license tokens (which you can check by using lsmon or WlmAdmin).
