Processing Unit Instance Configuration

You can configure different properties of the instances including the log levels and global variables using the BusinessEvents Enterprise Administrator Agent UI.

Click any instance name to open the page listing the properties instance categorized in different tabs. Each tab represents a specific set of properties. After editing the configuration properties, redeploy the instances for the changes to take effect.

Global Variables

The Global Variables tab lists global variables for the instance with their default values, which are taken from the CDD if present, else as defined in the project. Ensure that the "Service Settable" flag in the project is enabled for editing global variables using the BusinessEvents Enterprise Administrator Agent.

You can also override the global variable value and then redeploy the instance to make the change permanent. If needed, after deployment, you can also delete the override value using the BusinessEvents Enterprise Administrator Agent.

System Properties

The System Properties tab lists system properties for the instance. You can add, update, or delete the system properties. The instance needs redeployment for the changes to take effect.

BusinessEvents Properties

Using the BusinessEvents Properties tab you can add or override the effective CDD value of the BusinessEvents properties.

In CDD the BusinessEvents properties are specified in the following locations:

  • In property groups in CDD PU sections
  • In property groups in CDD agent sections
  • In property groups at the "Cluster" (the top level) in the CDD

For properties with the same name specified in multiple places in the CDD, the PU level value overrides the agent level value which overrides the Cluster level value. This is called the effective CDD value.

You can override the value for the effective CDD value of a BusinessEvents property using the BusinessEvents Enterprise Administrator Agent. After deployment, the override value is placed in the instance TRA file. You can also delete the override value using the BusinessEvents Enterprise Administrator Agent.

In addition to the default CDD properties, you can also add new properties and also delete these newly added properties.

JVM Properties

You can update the following JVM properties for the instance:
  • Initial heap size (-Xms)
  • Maximum heap size (-Xmx)

Deploy the instance at least once before updating these properties. Thus, the default values are loaded from the target machine be-engine.tra file.

Log Levels

You can also change the log level of an instance using the BusinessEvents Enterprise Administrator Agent. You can specify multiple logger patterns and set a level for each of the patterns. The run time will evaluate these patterns and log levels are applied accordingly. Log level changes can be applied directly to running instances or they can be deployed, so that the changes are permanent.

Group Operation Support

You can also update configuration properties for multiple instances as a group operation.
