You run the samples and tutorials using the sample server. The sample server runs on WebSphere® Application Server Network Deployment.
Operational Decision Manager contains a sample server. The sample server provided is a profile on WebSphere Application Server.
WebSphere Application Server is installed as part of Decision Server. It provides a default, pre-configured execution environment for Rule Execution Server and for Operational Decision Manager samples and tutorials, for the convenience of Operational Decision Manager users.
The sample server is only installed on distributed platforms.
For Decision Server Rules, if you do not want to use the provided sample server, it is not mandatory to use of WebSphere Application Server. All Java™ EE-dependent features can use an alternative Java EE application server from the list of Operational Decision Manager supported platforms. However, the event runtime requires WebSphere Application Server Network Deployment.
You can start and stop the sample server from the start menu shortcuts, directly from the command prompt, or from the samples console in Rule Designer. The samples console also displays message traces produced by the Sample Server.
Single sign-on (SSO) authentication is activated for the sample server. SSO allows users to log in once and gain access to all applications without being prompted to log in again for each of them. If you use different sign-on credentials for the applications on the sample server, for example when performing certain samples and tutorials, you get an error message when you attempt to sign in to the second application.
To avoid this issue, you must sign out of the first console and then sign in to the second console. Alternatively, you can sign in to all of the applications on the server using the credentials that you entered at installation time.
