UniPrint Infinity High Availability Setup

Introduction

In any environment a print service outage is at the very least an inconvenience and in some environments it can be much more serious. To ensure maximum uptime and to eliminate any single points of failure, UniPrint Infinity can be set up for High Availability (HA).

The information outlined in this document is considered to be an advanced setup for UniPrint Infinity and a member of the UniPrint Support team should be consulted prior to commencing work.

High Availability Setups

Microsoft Failover Cluster

For more information on setting up UniPrint Infinity in a Microsoft Cluster, refer to the UniPrint Infinity Cluster Guide.

UniPrint Infinity HA Setup

When it is not possible to setup Microsoft failover clustering, follow the guidelines in this document to setup UniPrint Infinity in an HA

configuration.

Although UniPrint Infinity can be setup with only two Bridges or only two Print Servers, this document will focus on setting up UniPrint Infinity with two Bridges, two Print Servers and an external database, such as Microsoft SQL Server. This setup provides the best protection against UniPrint service failures.

NOTE: A redundant Bridge setup will only fully protect against a

UniPrint service outage on a Bridge. In the event of complete failure of the Bridge or Print Spooler service on the Bridge, some printing services, such as Microsoft Office 2010 or later, will be unavailable whilst others will experience a delay in printing. This is due to the underlying Microsoft Windows print system and how it deals with a server/Print Spooler service being available.

Before Installing UniPrint Infinity

Setting up UniPrint Infinity in an HA setup, requires an external, centralized database, such as Microsoft SQL Server. Before installing UniPrint Infinity, it is recommended that the following tasks be completed:

• Create a new database or instance.

• Execute a custom script on the new database. A custom script for Microsoft SQL Server is included in the UniPrint Infinity installation package and can be found in the Admin\HA SQL Script folder. • Create a system DSN connection from both Bridges and Print Servers

to the new database.

Setting up an external database will enable Printer Profiles and PrintPAL mappings to be replicated and reduces interruptions to SecurePrint and the Statistics modules.

The following instructions are purposely generalized. For detailed

instructions, refer to the documentation for your specific database version and its tools.

Setting up an External Database

1. Install the database application and create a new database, referred to as UniPrintDB throughout this document. Note: Microsoft SQL Express 2014 with Tools is free and is more than adequate for testing purposes. 2. Execute the SQL script, UniPrint_MSSQL_SERVER.sql, against

(12)

3. Confirm that the tables have been created.

Creating ODBC Data Sources

A System DSN connection needs to be created from both Bridges and Print Servers to UniPrintDB.

1. On all Bridges and Print Servers, click Start and then type ODBC Data Source. Click ODBC Data Sources.

(13)

Chapter 2: Before Installing UniPrint Infinity 7

3. Ensure that SQL Server is selected and then click Finish.

4. Enter a name for the database source and then select the SQL server where UniPrintDB resides.

5. Select With SQL Server authentication using a logon ID and

(14)

Password. Note: Windows NT authentication is not supported. Click Next.

(15)

7. Click Finish.

(16)

9. The UniPrint data source will now appear in the list. Click OK.

Connecting UniPrint Infinity to an External Database

The following steps are required, if the data source information was not provided during the installation of UniPrint Infinity.

After establishing a system DSN connection, the UniPrint Management Console on both Bridges and Print Servers need to point to UniPrintDB. Do the following on both Bridges and Print Servers:

1. On a Bridge or Print Server, open the UniPrint Management

Console.

(17)

3. Select Remote and then beside System DSN, select the UniPrint data source.

8. In the Ready to Install the Program dialog box, click Install. UniPrint installer will copy files to the destination folder.

9. Click Finish to complete the installation.

Configuring the Installation

(34)

To make this setup fully HA, both Print Servers need to point to both Bridges and the Application Server needs to point both Bridges. Both Bridges also need to point to each other. If change are made to the printer properties of a Gateway printer on one Bridge, then these changes will automatically be reflected on the other Bridge.

To do this, do the following:

1. On Print Server 1, open the UniPrint Management Console. 2. Under Properties & Settings, click Components.

3. Click to select UniPrint Control Service and then click

Properties.

(35)

5. To add a Bridge, click .

6. Enter the IP address of Bridge 2 and then click OK.

(36)

Bridge and if failure occurs, this print server will failover to the Bridge associated with the second IP address.

(37)

9. Repeat steps 1 to 7 on the Application Server, except enter the IP address of Bridge 2.

(38)

11. Repeat steps 1 to 7 on Bridge 2, except enter the IP address of Bridge 1.

After configuration is complete the HA Setup should look something the following diagram.

Confirming Correct Installation & Configuration

To confirm that the installation and configuration is correct, there should be two PrinterServerSID values in the registry.

(39)

2. Under the following key, there should be 2 PrinterServerSID values: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\Print\Printers\[PrinterName]\DsUser.

3. The printer will also be a proxy to two print servers on the UniPrint Management Console.

Modifying & Removing UniPrint

Before proceeding ensure that all user sessions have ended, and that new logons to the application server or virtual desktop image have been disabled.

(40)

Modifying a UniPrint Installation

To modify a UniPrint installation, you must either be logged in as the built-in “Administrator” or you must have UAC disabled. By design, modifying UniPrint as a user with administrative privileges does not give you sufficient permissions.

1. Click Start and then click the Control Panel tile. 2. Click Programs and Features.

3. From the list of installed applications, click to select UniPrint

Infinity and then click Change.

4. In the UniPrint Infinity Maintenance dialog box, click Next. 5. In the Program Maintenance dialog box, select Modify and then

Configuring UniPrint Infinity Features for HA

Some UniPrint Infinity features require additional configuration in order to function properly in an HA setup. These features include Printer Profiles and configuring the UniPrint NAS Service for SecurePrint.

Applying HA Licenses

Two separate license files corresponding to the two Bridges are required for the HA setup. Simply apply the license file to the corresponding Bridge. For detailed instructions on applying license files, refer to the UniPrint Infinity Administrator’s Guide.

PrintPAL

(42)

Printer Profiles

In recent releases of UniPrint Infinity, a Path registry value was introduced that allows for printer profiles to be stored in a shared network location. Setting this value allows for Printer Profiles to be replicated between the two Print Servers.

1. Create a shared location that is accessible by both Print Servers in your network, for example, \\FileServer01\UniPrint\Profiles.

2. On both Print Servers, open the Registry Editor, by clicking Start and then typing regedit.

3. Under the key:

HKEY_LOCAL_MACHINE\SOFTWARE\UniPrint\Profiles double-click the Path value.

4. Under Value data, enter the new path for the shared network location and then click OK.

5. Close the Registry Editor.

6. To ensure that this functions as intended the UniPrint Control Service must be run as a Domain user and this user must also be a local administrator. On both Print Servers, click Start, Administrative

Properties.

8. Click the Log On tab and then select This account.

9. Enter the credentials of a valid Domain user that is also a local administrator and then click OK.

10. Create and edit printer profiles on any Print Server. This only needs to be done on one of the Print Servers, since whatever profiles are created on one Print Server will automatically be reflected on the other Print Server. For detailed instructions on creating printer profiles, refer to the UniPrint Infinity Administrator’s Guide.

UniPrint NAS Service & SecurePrint

The UniPrint NAS Service is used to move SecurePrint jobs from the QueueJob folder to a shared network location.

1. Create a shared location on the network, for example, \\FileServer01\UniPrint\UPNAS.

(44)

3. Right-click the UniPrint NAS Service and then click Properties. 4. Click the Log On tab and then select This account.

5. Enter the credentials of a valid Domain user. 6. Open the Registry Editor.

16. Start the UniPrint NAS Service on both Print Servers.

Activating the UniPrint vPad

Activating the vPad in an HA environment is slightly different since the vPad has to point to both Print Servers and activation of the vPad should be done on a Print Server.

Follow these instructions for both the vPad device and the SecurePrint emulator.

(48)

Server Hostname or IP address is pointing to the wrong UniPrint Print Server or if only one is presented, tap Customize.

(49)

b. Change and add the IP address or hostname to that of both Print Servers and then tap to minimize the keypad.

c. Tap Apply.

(50)

2. The vPad will display the IP addresses of both Print Servers, with the currently connected Print Server in green.

3. From a Print Server, open the UniPrint Management Console. 4. Under Properties & Settings, click SecurePrint.

(51)

7. Once enabled, return to the vPad and the user name entry screen should appear.

Adding Printers to the vPad

After the vPad has been configured to point to both Print Servers, adding printers and other configuration tasks only need to be done on one Print Server, since SecurePrint settings are replicated to the other Print Server. For detailed instructions on other SecurePrint configuration tasks, refer to the

UniPrint Infinity Administrator’s Guide. To add a printer to a vPad, do the following:

(52)

3. Click to select an enabled vPad and then click Add Printers.

4. Click to select a printer and then to ensure users enter a password in order to release their print job(s), select Force Password. Note: To select multiple printers, click to select a printer and then hold down the SHIFT key for consecutive printers or the CTRL key for non-consecutive printers.
