This section gives an overview of use cases for centralized service models:
Calbro Systems is a telephone service provider that provides both landline services and cell phone services in a small rural town. Calbro Systems requires a service model that spans a large number of CIs. The needs of Calbro Systems can be met by a single BMC TrueSight Infrastructure Management Server that can accommodate a service model containing a large number of CIs and a Publishing Server that can publish these CIs. Such a service model allows Calbro Systems to perform the following tasks:
Calbro Systems is a telephone service provider that provides both landline services and GPRS phone services. Calbro Systems requires a service model that spans a large number of CIs. At present, a single BMC TrueSight Infrastructure Management Server can only accommodate a service model that contains a limited number of CIs and the Publishing Server can publish only few CIs at a time.
To build and manage a large number of CIs, Calbro Systems must be able to perform the following tasks:
To achieve these objectives, Calbro Systems needs to create a distributed service model.
Prerequisite: Calbro Systems has created a discrete service model on a Child Server. The service model has been promoted and published to the Child Server and can be viewed from the Central Server.
Assume that a database storage problem leads to a critical impact of the landline service database. If you view the service model in the Operations Console of the Central Server, not only the landline service database CI (impacting CI) but all its parent CIs are also impacted as illustrated below. That is, the impact is propagated from the impacting CI to all its parent CIs (impacted CIs).
Impacted discrete model
Consider the same scenario for a distributed service model. That is, the landline systems CI is the impacting CI and the impact is propagated to the parent CIs. The following figure illustrates the impacted distributed service model:
Impacted distributed model
You can view details about the CIs on the Related CIs area of the Details Notebook pane. Select a particular CI and click the Details Notebook pane to view its ID, cell details, details of its status and so on. For example, the Details Notebook pane of the discrete service model scenario would resemble the following figure:

To fix an impacting CI, perform the following steps:
