Qlikview Server Clustering

Qlikview Server Clustering

Prerequisites:

Following requirements have to be met before starting the QlikView Server cluster configuration:

• A QlikView Server license allowing QlikView Server clustering.  That means that the QlikView Server LEF must consist of an entry “NUMBER_OF_CLUSTER_NODES;X;;” where X is 2 or higher
• AccessPoint (based on IIS or QlikView Web Server), Management Service, Qlikview Distribution Service, Directory Service Connector are already installed on QlikView system in the network
• A domain user to run the QlikView services on every machine is available.
• A Windows Network-Share
• All QlikView Server cluster nodes need read /write access to the following data centrally stored:
• Server status files aka .pgo
• QlikView Documents aka QVWs
• QlikView Server Logs aka audit, session, performance, event logs

Step-by-Step Installation

1. Prepare the shared device:

Create folders for the files accessed by every QlikView Server cluster node.:

• QvRoot for the .pgo-Files
• QvMount for a Mounted Folder
• QvLogs for the Logfiles
• QvExtensions for the extensions
• QvTemp for the temp files

2. Prepare the cluster nodes:

On each planned QlikView Server cluster node perform the following configuration

•   Login as Administrator
•   Turn Off Windows Firewall 

 

•   Deactivate Internet Explorer Enhanced Security Configuration for Administrators

• Add Domain User the QlikView services should use to Local Administrators Group
• Start QlikView Server setup and install feature “QlikView Server” only

NOTE: Do not install any other services such as QlikView Management Service on multiple nodes in the cluster!

• During the setup check that you will specify the QlikView service account later 

• Do not restart the system immediately after install is completed, but
    o   Add QlikView service user to “QlikView Administrator Group”
    o   Change Logon setting of the QlikView Server Service to the QlikView Service user
• Restart the system

3. Configure QlikView Server-Cluster in QlikView Enterprise Management Console

• Open QlikView Enterprise Management Console and register QlikView Server licence with activated cluster nodes

• Add first QlikView Server cluster node below QlikView Servers

• Switch Root,Mount,Logs,Extensions and Temp Folders to Shared Device folder paths using UNC-syntax (i.e \\Fileshare\QvRoot)

• Press Apply and let QlikView Enterprise Management Console initiate restart of QlikView Server service
• Add each additional QlikView Server cluster node and activate them by entering control number of the registered QlikView Server license

• Press Apply and let QlikView Enterprise Management Console initiate restart of QlikView Server service on all nodes
• Verify all QlikView Server nodes are running

• Configure Load Balancing feature (Functionality see QlikView Server Reference Manual)
