FAQ


How can I use a product with a License Server license when offline?

For more information, please refer to the offline seats chapter of this manual. Look up the relevant product setup and look for info about going offline within the corresponding section.


What are the License Server minimum requirements?

License Server requires Java 1.6 to operate. Wherever possible, we recommend to run License Server using Java 8 or newer. Please note that Java 6 and Java 7 have reached their end of life and no longer receive regular security updates. Using these versions can open the License Server to certain security risks. The future releases of the ZeroTurnaround License Server might require Java 8 as the minimum Java version.

License Server has been built to run on any modern server hardware. Other minimum requirements include:

  • At least 50 MB of hard disk space for the main application.
  • The log file size and database size are dependant on License Server usage. We recommend keeping at least 1 GB of hard disk space available at any time. Setting the log level to debug or trace will have an impact on log file size.

How long is a seat valid?

Seats are permanently assigned to developers – they will not be returned to the seat pool when the developer is not actively using their license.

The client checks against the server after every 60 minutes. If you have checked out an offline seat, the client will not ping the server while the offline seat remains valid (1 to 15 days).


How can I remove users from the License Server?

You can block License Server users from the Users section. This user will still show up in user history, but will no longer be able to obtain a seat. This functionality is designed for scenarios where an employee has left the company and no longer requires the seat. The EULA stipulates that once a managed seat is assigned, it should not change ownership until the end of the license period.


Does ZeroTurnaround host a public instance of the License Server?

Yes. Your licenses are delivered through ZT License Management. When making a purchase, you will receive an activation link by email. Activating your account automatically enables you to distribute your licenses without having to set up an on-premise License Server. Please refer to the ZeroTurnaround License Management for more information.


Can I move a License Server installation?

Yes. You can move the License Server installation to a new machine or location. Follow these steps to achieve this.

  1. Copy the contents of the License Server folder (including the data folder) to the new location.
  2. Upon starting, License Server itself will need to be reactivated. This does not erase copied license and database information.
  3. All License Server users need to reactivate their JRebel or XRebel clients using the new License Server team URL.

ZeroTurnaround permits a seven day transition period for moving a License Server installation. ZeroTurnaround monitors these events to prevent misuse.
