# Configuring Licpoll Load Balancer

Licpoll Load Balancer is a program that balances out the number of licpoll jobs with the number of servers or products to poll by creating scheduler jobs for running licpoll based on the configured products in licpoll.xml, the defined maximum instances, and the defined weight threshold.

As a scheduler job, it runs:

when the scheduler starts
10 minutes before the start of every hour
when the scheduler job that runs the license configuration builder ends

The following sections will guide you on configuring the Licpoll Load Balancer behavior.

This task requires support's assistance. Please coordinate with them to ensure a smooth process.

# Requirements

Open iT Core Server
Activated Licpoll Load Balancer

# Configuring Max Instances

The maximum number of jobs the Licpoll Load Balancer can create is ten (10) by default. To change it, follow these steps:

Open licpoll.xml in the Components directory, which is by default in C:\Program Files\OpeniT\Core\Configuration\Components.

Locate and change the value of object node max-instances.

licpoll.xml
<Object>
	<Name>max-instances</Name>
	<Description>Max number of concurrent LicPoll processes</Description>
	<Value type="Int">6</Value>
</Object>

Save the changes.
Open a command prompt with Administrator level privileges.
Go to the bin directory, which is by default in C:\Program Files\OpeniT\Core\bin, run the command:
Command Syntax
```
 cd $BIN_DIR
```
Example
```
 cd C:\Program Files\OpeniT\Core\bin
```
Update the configuration file, run the command:
Command Syntax
```
 openit_confbuilder --client
```

Open licpoll.xml in the Components directory, which is by default in /var/opt/openit/etc/Components.

Locate and change the value of object node max-instances.

licpoll.xml
<Object>
	<Name>max-instances</Name>
	<Description>Max number of concurrent LicPoll processes</Description>
	<Value type="Int">6</Value>
</Object>

Save the changes.
Go to the bin directory, which is by default in /var/opt/openit/bin, run the command:
Command Syntax
```
 cd $BIN_DIR
```
Example
```
 cd /var/opt/openit/bin
```
Update the configuration file, run the command:
Command Syntax
```
 ./openit_confbuilder --client
```

# Configuring Weight Threshold

Any product that exceeds the weight threshold defined is given a job of its own, aside from the specified max-instances. The weight threshold is 120 by default. To change it, follow these steps:

Open licpoll.xml in the Components directory, which is by default in C:\Program Files\OpeniT\Core\Configuration\Components.

Locate the max-instances object node then add an extreme-weight-threshold after it.

licpoll.xml
<Object>
	<Name>max-instances</Name>
	<Description>Max number of concurrent LicPoll processes</Description>
	<Value type="Int">6</Value>
</Object>

<Object>
	<Name>extreme-weight-threshold</Name>
	<Description>The weight threshold for extremely huge products</Description>
	<Value type="Int">200</Value>
</Object>

Save the changes.
Open a command prompt with Administrator level privileges.
Go to the bin directory, which is by default in C:\Program Files\OpeniT\Core\bin, run the command:
Command Syntax
```
 cd $BIN_DIR
```
Example
```
 cd C:\Program Files\OpeniT\Core\bin
```
Update the configuration file, run the command:
Command Syntax
```
 openit_confbuilder --client
```

Open licpoll.xml in the Components directory, which is by default in /var/opt/openit/etc/Components.

Locate the max-instances object node then add an extreme-weight-threshold after it.

licpoll.xml
<Object>
	<Name>max-instances</Name>
	<Description>Max number of concurrent LicPoll processes</Description>
	<Value type="Int">6</Value>
</Object>

<Object>
	<Name>extreme-weight-threshold</Name>
	<Description>The weight threshold for extremely huge products</Description>
	<Value type="Int">200</Value>
</Object>

Save the changes.
Go to the bin directory, which is by default in /var/opt/openit/bin, run the command:
Command Syntax
```
 cd $BIN_DIR
```
Example
```
 cd /var/opt/openit/bin

Update the configuration file, run the command:
