Push Integration Mechanism

The components responsible for the ServiceNow integration are bundled in the ServiceNow Integration package, ServiceNow_Integration.zip.

The integration mechanism works as follows:

  1. The Integration job queries UCMDB for CIs and relationships.

    When an ad-hoc job is run from the integration point in the Integration Studio, the integration receives the names of the integration queries defined in the job definition, for that integration point.

    It queries UCMDB for the results of these queries (new, updated and deleted CIs and relationships) and then applies the mapping transformation according to the predefined XML mapping files for every TQL query.

    It then pushes the data to the Data Flow Probes.

  2. The integration job sends the data to ServiceNow.

    Next, on the Data Flow Probe side, the integration process receives the CI and relationship data sent from the UCMDB server, connects to the ServiceNow server using the Direct Web Services SOAP API, and transfers the CIs and relationships.

    Since the ServiceNow coalescing (CI reconciliation) mechanism is not available for the Direct Web Services API, a mapping of UCMDB CI IDs to ServiceNow SysIds is maintained on the Data Flow Probe. This mapping is used to update and delete CIs and relationships in ServiceNow.
