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)
