Introducing Array Manager

Use Array Manager to perform these tasks:

• Set up and manage an array of Tarantella servers, for emulator session load balancing.
• Configure array-wide settings, and settings for each array member.

You can use command-line tools for these tasks, if you prefer. See tarantella array and tarantella config for more information.

Only Tarantella Administrators are allowed to run Array Manager.

What you see

Array Manager has two panes, which you can resize.

• On the left, the Array pane shows the array members and all the areas you can configure.
• On the right, the Properties pane lets you configure those areas.

You can get help on any part of Array Manager: click the context help button at the lower right of the Array Manager window, and then click the part you want help on.

The Array pane

The Array pane shows all the areas you can configure. It's arranged as a tree:

• At the top of the tree are the array-wide properties. Changing attributes for these affects all array members. For example, in Tarantella Login properties you can set the login theme, which affects the login page that users see -- whatever array member they log in to.
• Expand the Array part of the tree to show all the array members. Choose Properties for an array member to show its current status.
• Expand the tree for an array member to show the configurable areas for that array member. Changing an attribute here affects only that array member.

You can also set up and dismantle an array:

• To add a Tarantella server to the array, click New Secondary and then type the server's DNS name.
• To remove a Tarantella server from the array, right-click it in the tree and then click Detach Server.
• To change the primary server in the array, right-click the server you want to become the primary server and then click Make Primary.

The Properties pane

The Properties pane shows all the attributes you can change for something.

In License Properties you can add and remove license keys: simply type each key into the empty boxes. As you type the last character in the key, the key is validated and becomes active. The summary updates to show your current licensing status.

You can remove a key by deleting the characters in the key. Removing the last character removes the key and updates the summary.
