General and installation

LimitationComment or workaround
When you install Rule Designer in Eclipse, you encounter several problems, including user interface issues, missing plug-ins, error messages, and broken About popup and Installation details button.When you install Rule Designer, Eclipse automatically updates selected plug-ins. It connects to Eclipse Marketplace, and installs the latest versions of the plug-ins. The plug-ins disable functionality in Rule Designer. For the workaround, see Resolving possible issues with Eclipse after updating Rule Designer.
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 your locale.When the survey does not support a 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

LimitationComment 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.
Your user role is changed while you have a session open, but the session does not apply your new role.You must log out completely, and then log back in to use the new user role.
The cloud portal is empty when you sign in to it for the first time.
Your cloud administrator must assign you a role before you can see the contents of the portal.
Deleting someone's account from the user management page might not stop that person 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 ID 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.

User group management REST API

LimitationComment or workaround
The internal group permissions are not defined in the REST API.
This limitation concerns the following endpoints:
 
You can view Decision Center groups by using the first two endpoints, and edit them by using the third one. However, there is no business impact because the permissions of internal groups are not defined at this level. 
The REST API methods cannot be used with SAML accounts.
Use service credentials to access the REST API.
 
For REST API methods that require the cloud administrator role, use the portal to assign the cloud administrator role to specific service credentials.
When you have a large number of existing users with an ODM role, you cannot invite someone and assign that person an ODM role in a single command.
You must split the invite into two steps:
1. Invite the person without specifying an ODM role:
POST /instance/services/users
...
{
  "user_id": "user@mail",
  "email": "user@mail",
  "given_name": "Firstname",
  "family_name": "Lastname",
  "details": {
    "preferred_language": "en"
  }
}

2. Then, assign that person an ODM role, for example, for developers:
POST /instance/services/groups/Developers/members
...
{
 "group_members": [
    {
      "member_id": "user@mail",
      "type": "user"
    }
  ]
}
When you use the REST API to assign a role to someone, that person retains any preexisting assigned role(s).Use the REST API to remove the no longer needed role(s).

The following requests return a 501 "Not Implemented" error:

  • POST /instance/services/groups
  • DELETE /instance/services/groups/{name}
Groups are managed internally, so group creation and deletion are blocked in the REST API.

2020.12 release: The following request returns a 501 "Not Implemented" error:

  • PUT /instance/services/groups/{name}/members
This API is blocked because updating group members when a group only has one member can cause problems.

Rule Designer

LimitationComment or workaround
You encounter PKIX issues while installing Rule Designer.
Follow these steps to resolve the issues:
  1. You start with a new installation of Eclipse IDE for Enterprise Java and Web Developers.
  2. An issue occurs with the p2 link that shows a PKIX cert build path error.
  3. Remove or uncheck all the links and URLs in Eclipse except the p2 URL.
  4. (If required) Install a new version of Java 21, for example, Semeru 21 or newer, or Oracle Java SDK/JRE/JDK 21(see IBM Operational Decision Manager on Cloud - Detailed System Requirements).
    1. Point to the new Java in eclipse.ini (see Installing Rule Designer).
    2. Change the java-home in the environment variables to point to the new version of Java.
  5. Download and install a fresh root certificate that originates from the p2 URL to the cacerts of the new Java (see Importing a security certificate in Rule Designer).
  6. Update eclipse.ini with the path and password for the updated cacerts.
  7. Keep a copy of the updated cacerts next to the current eclipse.ini.
  8. Restart Eclipse.
Note: These steps also resolve any issue that comes from using the wrong version of Java or Eclipse.
Users of Semeru JDK on macOS machines cannot use the Norwegian locale (no_No). They get an exception when loading a project.To work in Norwegian on Rule Designer, use a different operating system.
After installing Rule Designer from Eclipse with Install New Software, the Rule perspective does not open. The perspective is the main interface for Rule Designer.

Eclipse installs a version of the org.eclipse.draw2d plug-in that is incompatible with the installed version of Java. The plug-in prevents the Rule perspective from starting. 

Make sure you are using the correct version of Java for Rule Designer (see IBM Operational Decision Manager on Cloud - Detailed System Requirements).

In Eclipse, disable the Latest Eclipse Release setting before installing Rule Designer: 

  1. Open Preferences>Install/Update>Available Software Sites.
  2. Deselect Latest Eclipse Release.
  3. Now install Rule Designer from Eclipse.
The libraries that are available for the on-premises version of Rule Designer are not available for the cloud version of Rule Designer.None
When you launch Help > Help Contents in Rule Designer, the Eclipse help system displays a null topic instead of IBM Operational Decision Manager on Cloud.Open the null topic to see the help documentation for IBM Operational Decision Manager on Cloud.
When launching Help > Help Contents, the Eclipse help system displays a "Network Help Unavailable" error page that contains this message:
Do the following procedure:
  1. In Rule Designer, open Window > Preferences > Help > Content.
  2. Change the URL for the Knowledge Center from http://www.ibm.com/support/knowledgecenter/SS7J8H to https://www.ibm.com/support/knowledgecenter/SS7J8H.
Cannot install Rule Designer on older Eclipses.Use a Modeling Tools version of Eclipse.
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.
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.
(replace permission manager)
The Decision Center administrator 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 anyone from trying. When someone tries, 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, 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

LimitationComment or workaround
The IBM Knowledge Center does not define the property ruleset.decisionEngine.maxRunningTime in Built-in ruleset properties.This ruleset property is used to set the amount of time that a ruleset can run. The time is given in seconds. Only positive, non-decimal numbers should be used.
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

LimitationComment or workaround
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, your user group must be associated with the servers.

The cloud administrator must associate the user group with the target servers:

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

Tutorials

LimitationComment 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.
