BMC recommends that you use BMC Atrium CMDB in conjunction with BMC ProactiveNet. BMC Atrium CMDB provides support for efficient editing of the service model and provides integration with other tools that simplify the process of building the service model.

Working with the service model in BMC Atrium CMDB

When BMC ProactiveNet is integrated with BMC Atrium CMDB, you can create or update the service model using Impact Model Designer in the Atrium Core Console.

BMC recommends that you also use BMC Atrium Discovery and Dependency Mapping to automatically discover, and keep up to date, the infrastructure components, and their relationships, in your environment. 

Publishing the service model from BMC Atrium CMDB

After you create a service model in BMC Atrium CMDB, the service impact model must be delivered from BMC Atrium CMDB to BMC ProactiveNet. The process of distributing the service model from the source to BMC ProactiveNet is managed and controlled by the BMC ProactiveNet Publishing Server.

Setting the PublishToSIM attribute

Follow the guidelines below while setting attributes to the CIs:

  • Set the PublishToSIM attribute to yes - myself and my providers only for the top-level or root CIs in the service model.
    This option avoids unnecessary load on the BMC ProactiveNet and BMC Atrium CMDB network.
  • Set the PulishToSIM attribute to implicit for provider CIs in the service models.
  • Set the PublishToSIM attribute to yes - only myself to publish standalone CIs that are not a part of the service model (not related to other CIs).

Automatic publishing of updates

By default, the Publishing Server initiates a publish of new changes to the service models in the CMDB when a reconciliation job completes a merge into the BMC.ASSET data set. The new changes can include promotions initiated from Impact Model Designer, or Atrium Explorer, or Service Model Editor. This can be disabled in the Publishing Server configuration, in which case you have to manually initiate the publish using the publish command.

The BMC ProactiveNet Server and BMC Atrium CMDB must be deployed in the same subnet to reduce network round trip time.

Splitting models across multiple BMC ProactiveNet Servers

Service models may be split across multiple BMC ProactiveNet Servers. You might want to do this when the number of CIs in the service model exceeds 25000.

To publish the models to multiple servers:

  • Set the HomeCellAlias attribute of the CIs to the server on which you want the service model to be published.
  • Set the HomeCellAlias attribute only at the top most level of the model for which all the provider CIs go to the same server.
  • Confine individual service models, as much as possible, to a single BMC ProactiveNet Server.
  • Publish infrastructure CIs to the BMC ProactiveNet Server that is monitoring the CI and receiving events for the CI.
  • Run the Publishing Server with the enterprise mode enabled. By default, the Publishing Server is installed with the enterprise mode disabled (set to false). Edit the pserver.conf file and set Enterprise=T to enable the enterprise mode.

Migrating service models from BMC ProactiveNet to BMC Atrium CMDB

In some environments, service models may have been created in BMC ProactiveNet before BMC Atrium CMDB was implemented or made available. Use the sim2cmdb tool to migrate these service models to BMC Atrium CMDB. For information about sim2cmdb, see the BMC ProactiveNet Service Modeling and Publishing Guide from the PDFs page.

BMC ProactiveNet may also generate new computer system CIs, and occasionally other CIs, based on components being discovered by BMC PATROL monitors.

  • These CIs are not automatically imported into the CMDB.
  • After these CIs are discovered by BMC Atrium Discovery and Dependency Mapping, or otherwise added to the CMDB, the Publishing Server reconciles the CIs from the CMDB with what already exists in BMC ProactiveNet if these CIs are present in the CMDB. If the CIs are present only in BMC ProactiveNet but not in the CMDB, then they either need to be automatically discovered and added to the CMDB by BMC Atrium Discovery and Dependency Mapping, or manually created in the CMDB.

For information about upgrading a service model to BMC Atrium CMDB, see the BMC ProactiveNet Service Modeling and Publishing Guide from the PDFs page.

Discovering application infrastructure with BMC Atrium Discovery and Dependency Mapping

BMC Atrium Discovery and Dependency Mapping discovers infrastructure CIs (systems, application infrastructure, applications) and populates this data into BMC Atrium CMDB. You can use the new Collaborative Application Mapping feature of BMC Atrium Discovery and Dependency Mapping to improve accuracy and detail of the discovered models.

Rules in BMC Atrium Discovery and Dependency Mapping generate impact relationships based on discovered relationships. Higher level logical constructs (business services, organizations, user communities, and so on) and their relationships must be manually created.

BMC Atrium Discovery and Dependency Mapping keeps the discovered CIs up-to-date. Rules in BMC Atrium CMDB can automatically relate infrastructure CIs to technical services.

Service models populated from the BMC Atrium CMDB to BMC ProactiveNet depend on the accuracy and completeness of the CI data in BMC Atrium CMDB. BMC Atrium Discovery and Dependency Mapping must be used to populate BMC Atrium CMDB. BMC Atrium Discovery and Dependency Mapping and the related reconciliation in BMC Atrium CMDB help ensure accuracy. Ensuring accuracy and preventing duplicates is more difficult when other mechanisms are used to populate the CI data into BMC Atrium CMDB.

For information about BMC Atrium Discovery and Dependency Mapping, see the BMC Atrium CMDB Data Modeling Guide and the BMC Atrium Discovery online documentation.

If you do not use BMC Atrium Discovery and Dependency Mapping for service modeling, you must manually create all the infrastructure CIs and their relationships or import them into BMC Atrium CMDB using other tools. You must also manually keep the service model up-to-date. This approach is not recommended because of complications and potential data issues that may arise and must be addressed. This approach is also less efficient and more difficult to maintain.
