GRAT Configuration Options


Settings in GRAT

Description Valid values Default value Takes effect
group-by-level (group rules by business level)

There are three levels of rules: global, department, and process.

With value true, rules are grouped by business level:

  • All global rules belong to agenda group level0.
  • Department rules belong to agenda group level1.
  • Process rules belong to agenda group level2.

When a rule package is executed, level0 rules are executed first. Updates from this first pass then influence the department (level1) rules which are executed in the second pass. Updates from this second pass then influence any process rules (level2), which are executed in a third pass.

Note: The GRE option sequential-mode must be false when group-by-level is set to true.

When group-by-level is set to false, all rules are executed in a single pass. Changes made by a rule do not influence which other rules are executed (unless a Drools “update” or “insert” command is used).

CEP functionality

  • Genesys Web Engagement's CEP functionality strips out the rule attribute that indicates which level a rule is associated with. So, the setting of the group-by-level has no influence on rule execution.


true Immediately

Specifies the maximum number of different users that may be connected to the server. Multiple connections from the same user ID are only counted once.

Any positive integer

99 After GRAT (re-)start

Specifies the amount of time (in minutes) a client session can have no communication with the Rules Authoring Server before timing out. If no value is specified, the timeout (if any) defined by the application server applies. If the value is less than or equal to 0, the session will not time out.

Any positive integer

30 Immediately

The amount of time (in minutes), prior to an expected timeout, for a user to be warned of a pending timeout. If no value is specified, or if the value is less than or equal to 0, the default warning period of 1 minute will be used. For example, if you set the value of this option to 3, the user will be warned 3 minutes prior to an expected timeout. This warning dialog box will prompt the user to extend the session. If the session is not extended, the user will be logged out and the login dialog box will be displayed. Any unsaved changes that the user made during their session will be lost.

Any positive integer

1 Immediately
This option controls whether or not the rules authoring tool enables strict mode in the DROOLS rule compiler. Strict mode will cause the compiler to catch common mistakes when the rule author attempts to validate or save a rule.


true Immediately

Indicates whether to verify the TCP address of the application deploying rules to be that of an associated Genesys Rules Engine.


true Immediately

Specifies the maximum number of versions to display for any published template.

Minimum value 1

3 Immediately
deploy-response-timeout (not in application template by default)

Specifies the timeout (in seconds) applied to the deployment of a rule package.

Any positive integer

300 Immediately

Specifies whether users must add a check-in comment when committing changes to rules. These comments show up when viewing package history. If the value is set to false (default), users can save changes to rules without specifying a comment.


false Immediately
Specifies whether users can deploy only a package snapshot. If the value is true, users can only deploy a package snapshot. If false (default), users can deploy either the LATEST package or a snapshot.


false Immediately
encoding (not in application template by default)
Activates Unicode support for the conversion of data between the local character set that is used by Configuration Manager and the UTF-8 encoding that is used by the Rules Authoring Server. By default, code page conversion is disabled. To activate this functionality, set this option to the name of a converter that can translate the local character set to UTF format. The converter that is suitable for a particular deployment can be found by using the ICU Converter Explorer. There is no default value for this option. For valid values, see the ICU Home > Converter Explorer pages (http://demo.icu-project.org/icu-bin/convexp). After GRAT restart

The GRAT server builds and maintains a cache of the rules repository database (for example, index files, and so on), and stores this on the file system under WEB-INF/classes/repository. The cache improves performance when accessing frequently used rules, calendars, and so on. However, this cache must stay synchronized with the rules repository database.

Normally, if GRAT is restarted, it re-uses the existing cache, which is synchronized with the rules repository database. In this case, the clear-repository-option should be set to false (default).

However, if you are configuring a second GRAT for cold standby (see High Availability Support), this option should be set to true for both the primary and the standby instances of GRAT. Since either GRAT could be brought online in the event of a failure, this option forces GRAT always to rebuild the cache and re-synchronize it with the rules repository database. Setting this option to true can delay the startup of GRAT, since the cache must be rebuilt, but it ensures that it is properly synchronized with the rules repository database.


false After GRAT (re-)start
evaluate-decision-table-rows-top-down (new in 8.5.0)

Determines the order that the Decision Table rows are written out to the DRL. The default value is false, meaning that the rows are executed from the bottom up. If you change this default option, the behavior of GRAT's Test Scenario feature changes immedately, but you will need to re-deploy the rule package in order for the change to be observed in GRE.


false Immediately
single-sign-on (new in 8.5.0)

Note: This configuration option should only be used when deploying in a Genesys Engage cloud single-sign on environment, and does not apply for Genesys on-premise customers deploying GRS.

Indicates the login method: either single sign-on, or legacy login. With value false, the /index.jsp page will redirect to /login.jsp for legacy user login. With value true, then /index.jsp will redirect to /singlesignon.


false After GRAT (re-)start
link-to-hub (new in 8.5.0)

Note: This configuration option should only be used when deploying in a Genesys Engage cloud single-sign on environment, and does not apply for Genesys on-premise customers deploying GRS.

This option specifies the URL to which GRAT should redirect once the GRAT SSO session completes. This URL is used in two situations:

  • First, when the user clicks the log out button in GRAT, the browser will be redirected to this URL.
  • Second, if an SSO login is successful but the subsequent login to Configuration Server fails, then an error box is displayed to the user. Once the error box is dismissed, the browser will be redirected to the specified URL.

Note: The user must have logged in via SSO for this to occur.


No default value After GRAT (re-)start
decision-table-enable-wildcards (new in 8.5.001)

Controls whether the wild card feature is enabled in decision tables.


true After GRAT (re-)start
help-file-url (new in 8.5.001)

Specifies the base URL location of online help for GRAT. You can specify a local protected URL to install the wiki Help files if your organization prefers.


http://docs.genesys.com/Special:GRATHelp After GRAT (re-)start
use-legacy-language-pack-webhelp (introduced in 8.5.001 and removed in release 8.5.1)
With value true, when the GRAT user clicks the Help button in non-English environments, GRAT will use the legacy WebHelp files shipped with the various language packs. These legacy files may not reflect the full set of current functionality. With value false (default), GRAT will retrieve online Help from the docs.genesys.com website in the desired language (if available). In release 8.5.1, translated online Help is available, so this option is not required.


false After GRAT (re-)start
context-services-rest-api-protocol (new in 8.5.001)

The protocol that GRAT uses for the Context Services metadata REST API. Valid values are:

  • http
  • https

http, https

http After GRAT (re-)start
context-services-rest-api-host (new in 8.5.001)

The hostname of the Context Services that GRAT connects to.


After GRAT (re-)start
context-services-rest-api-port (new in 8.5.001)

The port of the Context Services metadata API


After GRAT (re-)start
context-services-rest-api-base-path (new in 8.5.001)

The base path of the Context Services API.

/ After GRAT (re-)start
list-object-use-name (new in

Enables users to control whether either the name or the display name of a Configuration Server list object is encoded in the DROOLS rule file.

true/false After GRAT (re-)start
enable-nested-solutions (new in

Controls whether users can create new rule packages under any node of the hierarchy. For iWD, it is recommended to set this option to false.

true/false false After GRAT (re-)start
deploy-method (new in

Enables users to override the automatic detection of the protocol to construct the "callback" URL used by GRE to fetch the DRL. GRE will use the selected method to connect with the GRAT server during deployment.
