General

Limitation Comment or workaround
In the cloud dashboard for monitoring the usage of decisions and artifacts, the range selected in the date picker must not exceed 365 days between the start date and the end date. N.A.
A customer survey opens in Operational Decision Manager on Cloud. The language of the survey does not match the language of my locale. When the survey does not support the user's locale, it opens in English by default.
If you change the language of your browser when you have the cloud portal open on your computer, the language of the portal does not change immediately. If your user profile language is set to Browser language (default) and you change the language of your browser, you must log out of the cloud portal, and then log back in to display the portal in the selected language.
If you receive an error message while generating service credentials, the contents of the error message might not be fully localized to the language of your profile. None
The sample projects are in English. You must use the projects in English in your instance of Operational Decision Manager on Cloud.
Restrictions apply to using Operational Decision Manager on Cloud with on-premises versions of Operational Decision Manager. See IBM Operational Decision Manager on Cloud Compatibility.

Cloud environment

Limitation Comment or workaround
When sending cloud invitations, the plus character (+) is not supported in email addresses. Do not use email addresses that contain the plus character. When someone's email address contains a plus character, obtain an address for this person that does not contain the character.
The logout link redirects you to the login page, but it does not close your cloud session. When you refresh an open application such as a Decision Center console or the Rule Execution Server console, you see that you are still logged in. You must log out of each open application to fully log out of the cloud portal.
Some system messages refer to IBM Business Process Manager (BPM). Operational Decision Manager on Cloud shares its platform with IBM BPM. Some system messages that apply to both products mention only IBM BPM. These messages can include error messages and password reset notification email messages. Treat these messages as Operational Decision Manager on Cloud messages.
When you try to log in to the portal, you might get a message that says the portal is currently unavailable. Try again later. If the problem persists, contact your cloud administrator.
When a user is logged in and the user's role is changed, the user does not see the change in the open session. The user must log out completely, and then log in again to see the change.
When a new user signs in to the cloud portal, no applications are shown. The release manager must assign the user a role before the user can see the applications. By default, the role of all new users is set to none.
Deleting an account from the user management page might not stop the user of the account from continuing to work in an already open session of the portal. Pending the closing of the session, the behavior of the session cannot be guaranteed.
When a session times out, it can leave a window that looks logged in, or a blank window with no apparent error. To continue working, you must log out, and then log back in.
If you call a decision service from a client application and the user ID or the password cannot be authenticated in the cloud portal, you receive an HTTP status code 302 error: Moved Temporarily. If you receive this message, check that the user name and password are still valid in the cloud.
Mail servers might block invitations to join cloud work groups. If a team member does not receive a cloud invitation, check whether a mail server is blocking the invitation. If so, change the server to allow the team member to receive messages from Operational Decision Manager on Cloud.

Rule Designer

Limitation Comment or workaround

Cannot install Rule Designer on Eclipse.

Use a Modeling Tools version of Eclipse.

In macOS, if you use the ruleflow editor or decision table editor, you might lose your Eclipse workspace. Work on the artifacts in either Decision Center or a virtual machine.
Eclipse does not start properly in macOS Sierra. Do the following:
  1. Download Eclipse for macOS and decompress the file.
  2. Open a terminal in that folder and run the following command: xattr -d com.apple.quarantine Eclipse.app/
  3. Proceed with Rule Designer installation.
You cannot simultaneously connect a Rule Designer workspace to more than one instance of Operational Decision Manager on Cloud. To publish a decision service to multiple instances, for example, you must have a separate Rule Designer workspace for each instance. You can, however, deploy a RuleApp from a decision service to multiple runtime environments in different Operational Decision Manager on Cloud subscriptions.
On macOS X, some keyboard shortcuts and mouse interactions are different or inactive in some Rule Designer editors. The differences include the following items:
  • In editors for decision tables, decision trees and ruleflows, instead of Cmd+C and Cmd+V for copy and paste, you must use Ctrl+C and Ctrl+V.
  • Cmd+S for saving inside an editor, and Cmd+Z and Cmd+Shift+Z for undo and redo do not work. For these actions, use the file and edit menus, or the toolbar icons where available.
  • In the ruleflow editor, you cannot drop packages into the editor. Create a rule task, and configure it by selecting packages in the properties view.
  • In the decision tree editor, you cannot move nodes.
When you enforce security on a project that contains multiple projects and publish the project to Decision Center, security is not enforced on all the projects. The permission manager must enforce security on the projects in Decision Center.
When you try to create a connection to Rule Execution Server, Rule Designer does not save your authentication information. Run the Configure Operational Decision Manager on Cloud connection wizard, and then use the Add Rule Execution Server connection wizard.
When you try to synchronize Rule Designer and Decision Center without configuring an Operational Decision Manager on Cloud connection first, an exception prevents you from completing the wizard. Do one of the following:
  • Configure the Operational Decision Manager on Cloud connection before you run the synchronization wizard.
  • Reinstall Rule Designer from the cloud portal to get the latest updates.
When you fail to connect Rule Designer to the cloud portal by using the connection wizard, you get a blank page and no error message. Reenter the URL for the cloud portal. If the problem persists, check that you are using the correct URL for the portal.
The REST execution test produces an error when you use a RuleApp that has the character "é" in its name. Change the name of the RuleApp to remove the special character.
When the authenticated session with the cloud portal expires, synchronization between Rule Designer and Decision Center fails. Run the connection wizard, and then try to synchronize again.
Deployment of decision services from Rule Designer to the Operational Decision Manager on Cloud staging and production Rule Execution Server consoles is forbidden. However, nothing currently stops the user from trying. The deployment fails, and an error message and a call stack are displayed in an HTML report. From Rule Designer, you can deploy to the development environment on the cloud, but not to the test and production environments.
You cannot connect to Operational Decision Manager on Cloud by using the on-premises Rule Designer. Use the Rule Designer that is provided in the Operational Decision Manager on Cloud portal.

Rule Execution Server

Limitation Comment or workaround
A production application cannot invoke a decision service through a SAML account. The application must use a basic cloud account to log in to the portal and invoke the decision service. Contact your cloud administrator for a cloud portal account. The administrator can also provide service credentials, which are specifically calling applications.
Rule Execution Server does not run decision service projects deployed from older versions of Rule Designer. To use decision service projects from older versions of Rule Designer, you must deploy or publish the projects from the cloud Rule Designer. You can download the latest Rule Designer from the Operational Decision Manager on Cloud portal.
When you access the Rule Execution Server console, an exception might be thrown. This error is due to an unexpected behavior in the JavaServer Faces (JFS). Log out, close the browser, and start over.
When you use a SAML federated account to access a Rule Execution Server console directly by its URL, you get an error message. Refresh the page.

Decision Center Business console

Limitation Comment or workaround
The decision modeling service is only available in the English verbalization. To use the decision modeling service, you need a customer subscription with a persistence locale set to English. You cannot use the service in another language. The persistence locale is set when a subscription is provisioned for a client.
Cannot find the customization tab that is described in the IBM Knowledge Center. The IBM Knowledge Center introduces a customization tab for the Business console in the 2019.06 release. The tab is not included in the cloud version of the console.
The branch search function fails to find artifacts.

This problem relates to the indexing of your repository:

  • The search function is disabled when the repository is being refactored. Wait a few minutes and try the search again.
  • If the search function continues to fail, your instance of Operational Decision Manager on Cloud might need to be refactored.
To see deployment configurations that have multiple target servers, the current user's group must be defined on all the servers.

The administrator of the instance of Operational Decision Manager on Cloud must associate the current user's group with all the target servers:

  1. Log in to the Business console with an administrator account.
  2. Open Administration > Servers.
  3. Associate the user's group with the servers.

For existing deployment configurations, the administrator must edit them to take into account the change.

Having trouble with webhook notifier. To use a webhook notifier, it must be accessible on a public address.
In the Administration > Servers tab in the Business console, you cannot add a decision runner server from another instance of Operational Decision Manager on Cloud. None
In the Business console, you cannot change the name of a group. Contact your release manager or cloud administrator.
A group name longer that 52 characters produces an error when you modify it, and you cannot use the group in the project security tab. Limit group names to 52 characters or fewer.
Creating a group name with an apostrophe in the Business console produces an error. Do not use special characters in group names.
The Business console displays an error when you reopen it after opening other consoles. Open the Rule Execution Server or Enterprise console in the portal, and then try to open the Business console again.

Decision Center Enterprise console

Limitation Comment or workaround
The decision tree editor can replace characters with squares in labels. The decision tree editor displays some characters in the GB18030 character set as squares in labels.

Tutorials

Limitation Comment or workaround
The getting started tutorial refers to test and production environments that are not available to Express users. Express users can still use the tutorial, but they should ignore the sections on the test and production environments. These environments are only available in the full version of Operational Decision Manager on Cloud.
