Decision Center parameters

Set parameters to customize the behavior of Decision Center. The parameters include timeout values, upload sizes, and paths to repositories.

Context parameters

The following list shows the context parameters. You implement them through the web.xml file.

Timeout value

This parameter is used to modify the timeout value that is associated with transactions. The value is in seconds.

Table 1. Timeout context parameter

Parameter name	Default value	Change default value	Platform
ilog.rules.decisioncenter.transaction.timeout	600	6000	Operational Decision Manager

Path to the configuration file

This parameter is used to define the path to the configuration file to use it to set up a ready-to-use Decision Center repository. If not specify, no automatic setup is provided.

Table 2. Path to the configuration file parameter

Parameter name	Default value	Platform
com.ibm.rules.decisioncenter.setup.configuration-file	/config/decisioncenter-configuration.properties	Operational Decision Manager

Path to custom configuration file

This parameter is used to define the path to the custom user configuration file to use it to set up a ready-to-use Decision Center repository. If not specified, the default Decision Center configuration file is provided for automatic setup.

Table 3. Path to custom configuration file parameter

Parameter name	Default value	Platform
com.ibm.rules.decisioncenter.setup.overridden-configuration-file	./config/overridden-decisioncenter-configuration.properties	Operational Decision Manager

Host HTTP header protection configuration

When enabled, this parameter provides a list of trusted hosts separated by semicolons. Each host must be a valid regular expression, for example, enableHostsAllowlist=true,hosts=host1.com;*.company.com;localhost:* This parameter is also used for the logout redirect parameter. Though not recommended, you can add the scheme here, like https://ibm.com or a wildcard *ibm.com.

Table 4. Host HTTP header protection configuration parameter

Parameter name	Default value	Platform
com.ibm.rules.decisioncenter.TRUSTED_HOSTS_CONFIGURATION	enableHostsAllow=false,hosts=ibm.com	Operational Decision Manager

Other properties

The following list shows other properties.

Enforce author-approver restriction

Prevent an author from also being an approver in a change activity. When you set this property to true, an error appears when a user tries to add an approver who is already an author.

Table 5. Maximum file size property

Property name	Location	Default value	Platform
decisioncenter.preventActivityAuthorToBeApprover	WEB-INF/lib/decisioncenter-iweb-core-V.R.M.F.jar/com/ibm/rules/decisioncenter/web/core/preferences.properties	false	Operational Decision Manager

Maximum file size

This parameter shows the maximum file size in bytes (20 MB).

Table 6. Maximum file size property

Property name	Location	Default value	Platform
maxUploadSize	WEB-INF/spring/applicationContext.xml	20000000	Operational Decision Manager

Thread pool task executor

This property is for configuring a ThreadPoolExecutor in a bean style by setting up the values for the instance variables. This parameter exposes bean properties for configuring a java.util.concurrent.

Table 7. ThreadPoolTaskExecutor property

Property name	Location	Default value	Platform
org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor	WEB-INF/spring/applicationContext.xml	xxx	Operational Decision Manager

Timeout

This property shows the number of milliseconds before a request is automatically stopped. The default value of 0 means there is no timeout.

Table 8. Timeout property

Property name	Location	Default value	Platform
xhrTimeout	WEB-INF/lib/decisioncenter-iweb-core-V.R.M.F.jar/com/ibm/rules/decisioncenter/web/core/preferences.properties	0	Operational Decision Manager
