Data models

CMDB version differences

The default mapping works with CMDB versions 7.5, 7.6, and 7.6.03 and later. The data model in each is slightly different.

  • BMC_Impact relationships are not normally created with CMDB 7.6.03 and later, since the CMDB automatically maintains them itself. See the information about impact relationships for more details.
 Click here for reference information on impact and the data models.

Different versions of the CMDB have subtly different data models. Syncmappings can support multiple data models with datamodel declarations. CMDB data models are assigned simple integer values:

Data modelCMDB versionsEffect

6

7.6.03 and later

HasImpact and ImpactDirection attributes are set as appropriate.

5

7.6.03 and later

Only to be used with legacy SIM version 7.4. BMC_Impact relationships with Name “ImpactOnly” are created.

4

7.6.03 and later

No impact details are set by BMC Discovery. They may be set by Impact Normalization in the CMDB.

3

7.6 before 7.6.03

BMC_Impact relationships with name “IMPACT” are created.

2

7.5

BMC_Impact relationships with name “IMPACT” are created.

BMC_ComputerSystem

The root SNMPManagedDevice node is mapped to a root BMC_ComputerSystem CI with the following attributes:
