Redundancy Page

License server redundancy provides an automatic failover solution to keep your print production environment running seamlessly in the event that one license server fails.

In Administration Console, you can configure redundancy by setting up license servers in a backup relationship that uses two servers or in a triad relationship that uses three. Then, if the main or primary server cannot be reached by a BarTender client for any reason, the client automatically connects instead to the other servers in the relationship.

Use the Redundancy page to specify the server redundancy relationship that you want (backup or triad) and to configure its properties.

After you configure the relationships that you want, the options that appear on the Redundancy page vary depending on the relationship types, as follows:

Server information also appears on the other pages in the Licensing section of Administration Console. A triad relationship is treated like a single license server, and it appears on these pages when one of its three servers is active.

Backup Relationship

In a backup relationship, you configure a main license server and a backup license server. These servers host different licenses but share the same settings. The data is periodically synchronized between the main server and its backup server so that the backup server can take over the responsibility of the main server when needed.

When you click Setup Server Redundancy and then specify a backup relationship, the Redundancy Setup wizard guides you to do the following:

Select the server that you want to use as the main server.
Select the server that you want to use as the backup server.
Map the licenses from the main server to the backup server so that if the main server fails, the backup server is used.

After you configure your servers, they are displayed in a table on the Redundancy page. You can manage these servers by using the Backup Relationship Setup wizard. To access this wizard, use one of the following methods:

Right-click a server to display a menu that provides management options, as follows:

The first option that is listed indicates the page in the Backup Relationship Setup wizard that applies to the selected server (for example, when Manage and Export Server Settings from Main Server appears in this list and you click this option, the wizard starts on that page).
The second option, Dismiss Backup Relationship, starts the wizard on the Dismiss a Backup Relationship page so that you can dismiss the relationship.

Use the and icons, as follows:

When you point to the icon, the page in the Backup Relationship Setup wizard that applies to the selected server is displayed. Click the icon to start the wizard on that page.
Click the icon to start the wizard on the Dismiss a Backup Relationship page so that you can dismiss the relationship.

The table also indicates the online status of each server. When the following icons are displayed, they indicate the status of the connection and synchronization between the servers:

Specifies that the servers are connected and synchronized.

Specifies that the servers are connected but not synchronized.

Specifies that the servers are not connected but are synchronized.

Specifies that the servers are not connected and not synchronized.

Triad Relationship

In a triad relationship, you configure three license servers to act as primary, secondary, and tertiary servers. These servers host the same licenses and share the same settings, so they behave like a single server.

When the primary server connects to either the secondary or tertiary server, it becomes the active server and can then process BarTender client requests. If the primary server fails for any reason, the secondary server tries to connect to the tertiary server. If the connection is made, the secondary server becomes the active server and can then process requests. BarTender clients automatically connect to whichever server can process their requests.

When you click Setup Server Redundancy and then specify a triad relationship, the Redundancy Setup wizard guides you to do the following:

Select the three servers that you want to use.
Assign roles to the servers (primary, secondary, and tertiary).

After you configure your servers, they are displayed as a diagram on the Redundancy page. The following options are available:

: Opens the following menu of management options for the triad:

Change Triad Roles: Starts the Change Triad Roles wizard so that you can change the role of the selected server.
Replace Triad Node: Starts the Replace Triad Node wizard so that you can replace the selected server with a different server.
Fix Connection Problem: Starts the Fix Connection Problem wizard so that you can reestablish connection to the node.
Dismiss This Triad: Starts the Dismiss the Triad wizard so that you can dismiss the triad.
Move to Top: Moves the triad to the top of the list of triads. Available after you configure more than one triad relationship.
Move Up: Moves the triad up one position in the list of triads. Available after you configure more than one triad relationship.
Move Down: Moves the triad down one position in the list of triads. Available after you configure more than one triad relationship.
Move to Bottom and Collapse: Moves the triad to the bottom of the list of triads and collapses it. Available after you configure more than one triad relationship.

Name: Specifies the name of the triad.
Append the current Active server's name to triad: Specifies that the name of the current active server is added to the triad.
Licenses: Specifies the number of licenses that the triad includes. Read-only.
Status: Displays a diagram that shows the three servers in the triad and their relationship to one another. The arrows in the diagram indicate the connection status between the servers.
