License properties (array-wide)

The License Properties panel of Array Manager is in two parts:

• the top part allows you to see and manage your Tarantella license keys; and
• the bottom part shows a summary of your licensing.

License management

The license management part of the panel shows all the license keys currently installed in the array. The keys apply to all array members. When you move your mouse pointer over a license key, a tooltip displays which shows a breakdown of what's licensed by the key.

You can add and remove license keys in this area:

• To add a license key, type or paste the key into the empty boxes.
  As you type the last character in the key, the key is validated and becomes active.
• To remove a key, delete the characters in the key.
  When you remove the last character in the key, the key is deleted.

As you add/remove license keys, Tarantella updates the information in the license summary part of the panel.

There are some conditions for adding/removing license keys:

• You must add an Activation license key before adding any other license keys.
• You can only remove an Activation license key if all other Tarantella license keys have been removed.
• You can only add one Activation license key in an array.
• If you want to join a server with an Activation licence key to a different array, you will be warned that the joining server will have its Activation license key discarded.
• If you add an Advanced Load Management license key, you must also do a warm restart of the primary Tarantella server (tarantella restart --warm).
• If you remove all the license keys, Tarantella reverts to evaluation mode or expired evaluation mode, depending on how recently you installed Tarantella. You cannot log in to a Tarantella server when it is in expired evaluation mode. To license a server when it is in expired evaluation mode, you must either add a valid Activation license key (using tarantella license add) or join the server to an array that is already fully licensed.

Array Manager displays any invalid license keys with a red background. This may be for example, because the license key was entered incorrectly.

Licensing summary

The licensing summary part of the panel displays the current licensing status for the array. It shows:

• the Tarantella product you are licensed to use. This is either Tarantella Enterprise 3 or Tarantella Enterprise 3 EX
• the current license mode of the array. This is either:
  • Evaluation mode - the end date of the evaluation period displays in brackets.
  • Fully licensed - the text in brackets shows whether you are using concurrent user licensing or the length of the lease period (for named user licensing).
• a breakdown by Tarantella component of what's licensed.
  • For each connectivity component, it shows the number of users licensed, including the number of users covered by your Maintenance license key(s).
  • For other components, it shows whether the component is licensed.
  • For the Extended Array license, it shows the number of servers you can have in your array.
