GRE Configuration Options

Settings in GRE

Description	Valid values	Default value	Takes effect
deployed-rules-directory ( added to application template in 8.1.3)
Specifies the directory in which to keep the working copy of deployed rule packages. When a package is deployed, a copy of the deployed package is placed here. When the rules engine is restarted, all packages defined in this directory are loaded and made available for execution. Specifying a deployed-rules-directory is recommended. If a value is not assigned to the deployed-rules-directory, the rule packages are placed in the WEB-INF\config sub-directory within the genesys-rules-engine web application directory. At this location the deployed rule packages may be deleted when an updated .war file is deployed. If you choose to change the default value, ensure that the path exists and that the application server can write to the specified directory.		/GCTI/logs/GRS_Engine (8.1.3 onwards)	After restart
max-number-rule-executions
The maximum number of rules to be executed during a request. This is used to detect unwanted recursion when sequential-mode is false. If this maximum is reached an error is reported. May be set to -1 to denote no maximum.	Any positive integer or -1	10,000	Next rules execution
sequential-mode
Indicates whether to run the rules engine in sequential mode. In sequential mode, after the initial data set, no more data can be inserted or modified. This allows for the rules engine to operate in a simplified way.	true/false	false	On rules deployment
verify-deployer-address
Indicates whether to verify the TCP address of the application deploying rules to be that of an associated Genesys Rules Authoring Tool.	true/false	true	Immediately
esp-worker-threads (new in 8.1.2)
Specifies the maximum number of worker threads available when using the ESP interface to execute rules.	Any positive integer	5	Immediately
load-packages-on-start (new in 8.1.4)
Indicates whether to load deployed rule packages at application start up. If packages are not loaded at startup (value=false), then a package is loaded on its first execution request.	true/false	true	Immediately
json-hierarchical-driver (new in 8.1.4)
With value true, the JsonHierarchicalStreamDriver class is used to serialize JSON responses. With value false, the JettisonMappedXmlDriver class is used. The Jettison driver is unaware of the original data type and will try to detect numerical values and omit the quotes, whereas the JsonHierarchicalStreamDriver will maintain the data type.	true/false	false	Immediately
