Configure Load Balancer
In multiple Load Balancer setup, one of the Load Balancers will act as the primary load balancer. All other Load Balancers will act as secondary load balancers.
In the event of failure of the primary load balancer one of the secondary load balancers will take the charge of the primary one.
For all the load balancers, carry out the following configuration tasks:
Specify Cluster Node and Load Balancer related details in RegistryInfo.xml file
Setup port of the Load Balancer in RegistryConfig.properties file
Configure report engine
Configurations in RegistryInfo.xml file
Load Balancer setup places file RegistryInfo.xml in LoadBalancerConfig folder.
Figure 14: Snapshot of RegistryInfo.xml file
You need to specify the following information in this file:
- Specify details of all cluster nodes
- Specify details of this and other load balancers
Cluster Node related information
You need to specify the following information about all the cluster nodes in the cluster:
- SERVER IP: The IP address of the cluster node.
- PORT: The port at which cluster node will listen.
- TASK PRIORITY: Specify a positive integer between 1 and 6 both inclusive. Priority 1, 2 is for Low; 3, 4 is for Medium and 5, 6 is for High.
- TASK TYPE: Specify the option ‘All’.
- WEIGHTAGE: Specify percentage of the load that this cluster node should take.
This information needs to be provided as an entry under SERVER tag. Example:
<SERVER IP=”192.168.33.115″ PORT=”50003″ TASK_PRIORITY=”0″ TASK_TYPE=”ALL” WEIGHTAGE=”30″/>
Specify this information for all the cluster nodes.
Load Balancer related information
You need to specify IP and port of all the load balancers.
- REGISTRY IP: IP of the machine where Load Balancer is installed.
- PORT: Port at which that Load Balancer will listen.
This information needs to be provided as an entry in REGISTRIES tag. Example:
<REGISTRY IP=”192.168.33.115″ PORT=”60001″/>
Configurations in RegistryConfig.properties file
Load Balancer setup places file RegistryConfig.properties in LoadBalancerConfig folder.
Load Balancer reads value stored in REGISTRY_LISTENER_PORT property in RegistryConfig.properties file to know the listener port.
Example: REGISTRY_LISTENER_PORT=60000
Modify values of following properties
An alert through e-mail will be automatically be sent in error conditions like the server shuts down, it reaches not responding state, or goes out of memory. Specify the email ID where the mail should be sent.

Configure Cluster Node
Deploying License on a node
Each node generates its license request file in the path:
<ClusterInstalledPath>ClusterReportEnginebin
A license file must be obtained by submitting this request file to your vendor. The obtained license must be deployed by manually copying to the license file in the path:
<ClusterInstalledPath>ClusterReportEnginebin
Note: Separate licenses should be purchased for each report server node
Restart after license deployment.
Configure each of the Cluster Report Servers
For all the cluster nodes, carry out the following configuration tasks:
- Set path of report server in cluster.properties file
- Set the port of the Cluster node in cluster.properties file
- Set schedule preferences in cluster.properties file
- Make changes in run.bat file
Path and IP information of Intellicus Report server is set in cluster.properties file. This file is at path IntellicusClusterClusterReportEnginecluster folder.
Configurations in cluster.properties file
Cluster Report Server setup places file cluster.properties in IntellicusClusterClusterReportEnginecluster folder.
Modify values of following properties
In REPORT_ENGINE_FOLDER property, specify the location where Shared Intellicus Report Server is installed.
For example:
REPORT_ENGINE_FOLDER=//servers/IntellicusShared/ReportEngine
Here, “servers” is machine name on which Intellicus Report Server is installed.
REPORT_ENGINE_FOLDER= \192.168.33.65IntellicusSharedReportEngine
Here, 193.45.34.24 is IP on which Shared Intellicus Report Server is installed.
In LISTENER_PORT property, specify the port at which this cluster node will listen.
For example:
LISTENER_PORT = 50001.
Specify STANDALONE if Intellicus is running as standalone. Specify CLUSTERED if Intellicus is running in the form of a cluster.
Default: CLUSTERED
Example: DEPLOYMENT_TYPE=CLUSTERED
Making changes in run.bat
In run.bat file specify the path where Shared Intellicus Report Server is installed. This is set in line under REPORT_ENGINE_FOLDER. For example,
REPORT_ENGINE_FOLDER=//servers/ReportEngine
Here, “servers” is machine name on which Shared Intellicus Report Server is installed.
For example, REPORT_ENGINE_FOLDER= 193.45.34.24SharedIntellicusSharedReportEngine
Here, 193.45.34.24 is IP on which Intellicus Report Server is installed.
Making changes in shutdown.bat
In shutdown.bat file specify the path where Shared Intellicus Report Server is installed. This is set in line under REPORT_ENGINE_FOLDER. For example,
REPORT_ENGINE_FOLDER=//servers/ReportEngine
Here, “servers” is machine name on which Shared Intellicus Report Server is installed.
For example, REPORT_ENGINE_FOLDER= 193.45.34.24SharedIntellicusSharedReportEngine
Here, 193.45.34.24 is IP on which Intellicus Report Server is installed.
Configure each of the Cluster Web Servers
For all the cluster web server nodes, carry out the following configuration tasks:
- Set path of report server in ReportClient.properties file
- Make changes in run.bat file
Configure portal Property file
When clustering and load balancing is installed, portal needs to point to load balancers instead of pointing to report server.
This change is made in ReportClient.properties file available on machine on which Shared Intellicus Client (portal) is installed.
When Intellicus is installed in Jakarta, this file is placed at path:
IntellicusSharedJakartawebappsintellicusclientconfigReportClient.properties .
Change values of following properties:
REGISTRY_ENABLED
Set this property to TRUE. For example:
REGISTRY_ENABLED=TRUE
REGISTRIES
Specify all IP and port of all the load balancers separated only by semi colon (no space).
Example:
REGISTRIES=201.90.56.23:60000; 201.90.88.95:60002; *
Save the file after making changes.
Configure run.bat file
Modify run.bat file (IntellicusClusterJakartabin) to set the path to read ReportClient.properties
set PROPERTY_FILENAME=”-DIntellicus.propertyfilepath=192.168.33.65SharedIntellicusSharedjakartawebappsintellicusclientconfigReportClient.properties”
How Property values are used
When value of REGISTRY_ENABLED is FALSE, it is assumed that clustering does not exist and client sends request to the IP specified in REPORT_ENGINE_IP property.
When value of REGISTRY_ENABLED is set to TRUE, client sends request to the 1st load balancer IP specified in REGISTRIES property.
If that load balancer is not available, client sends request to next load balancer in the list.
At a time multiple load balancers may be active. IP needs to be specified only by primary load balancer.
If the load balancer that client communicates with is not the primary load balancer, then it provides IP of the primary load balancer to the client. (So that from next time all the client requests should go to primary load balancer).
The client then checks if the load balancer IP provided exists in the list specified in REGISTRIES property.
Note: If the IP exists or it does not exist but list also has *, client sends the request to that load balancer. If it does not exist in the list; and list does not have *, then the client fallsback to the IP specified in REPORT_ENGINE_IP property.
When client sends request to the primary load balancer, It provides IP of the server where the client should send this request.
Now that the client know server IP, it sends the request to that server.
Run sequence
There is no predefined running sequence. Any of the components can be started or stopped at any time.
To run load balancer
If the machine is re-started after setup and service was also installed during installation, it will automatically start the load balancer.
As one of the results of successful installation, the setup creates a short cut in the start menu:
Start > Programs > Intellicus > Start Load Balancer
Follow this path to click Start Load Balancer to launch the Load Balancer.
Note: The load balancer that boots first, becomes primary load balancer. If primary load balancer fails, any of the secondary load balancers will become primary load balancer.
To stop load balancer
From Start menu
As one of the results of successful installation, the setup creates a short cut in start menu:
Start > Programs > Intellicus > Stop Load Balancer
Click Stop Load Balancer to stop the Load Balancer.
From Service Icon
This is applicable when Service was also installed during installation, is currently running and Load Balancer was started by Service.
- Right-click the Service icon. A context-menu appears.
- Click the Stop Load Balancer
Service will stop the Load Balancer.
To run Cluster node
As one of the results of successful installation, the setup creates a short cut in the start menu:
- Start > Programs > Intellicus > Start Cluster Report Server
- Follow this path to click Start Cluster Report Server to launch the Load Balancer.
To stop cluster node
From Start menu
As one of the results of successful installation, the setup creates a short cut in the start menu:
- Start > Programs > Intellicus > Stop Cluster Report Server
- Click Stop Cluster Report Server to stop the cluster report server.
