Retrieval method of federation

With the retrieval method of federation, you create BMC Atrium Configuration Management Database (BMC Atrium CMDB) classes to represent data that is stored externally. The following topics enable you to view the relationships between federated data and BMC Atrium CMDB data through such tools as BMC Atrium Explorer and BMC Atrium Impact Simulator.

Supported data types in federation

As part of the process of creating a federated data class, BMC Atrium CMDB creates attributes to represent the fields on the external repository. The data type of each attribute must be one of the types supported by BMC Remedy AR System.

The BMC Remedy AR System data type of each attribute depends on the native data type on the external repository. For example, Double fields on a JDBC-compliant repository are created as BMC Remedy AR System Real fields in the federated data class. String fields on a CMDBf-compliant external repository are created as BMC Remedy AR System character fields in the federated data class.

Data types on the external repository do not change. The mapping occurs in BMC Atrium CMDB as part of creating the federated data class.

For more information about BMC Remedy AR System data types, see Database data types for view forms in the BMC Remedy Action Request System online documentation.

The following table lists the supported JDBC data types and their mapped BMC Remedy AR System data types. Only the listed data types are created as attributes in BMC Atrium CMDB federated data classes.
