Changes to the BMC Atrium CMDB for BMC Remedy ITSM
Version 8.0 of BMC Remedy IT Service Management made important changes in the way BMC Remedy ITSM stores the attributes that it uses to describe configuration items (CIs). If you have custom programs or integrations that use asset lifecycle attribute data, you should review this topic because you may need to make changes to your procedures.
Impact of changes to Asset Management CI data
Pre-8.0 versions of BMC Remedy ITSM extended the BMC Atrium Configuration Management Database (CMDB) data model by adding a number of attributes that were used to track Asset Management CI data. These attributes included information about costs, foundational data such as company and location, and lifecycle information. In version 8.0 of BMC Remedy ITSM, asset lifecycle data was moved out of BMC Atrium CMDB and placed in a new BMC Remedy ITSM asset management form, AST:Attributes. Lifecycle data remains available through joins of the BMC.CORE:BMC_BaseElement form and AST:Attributes. This change occurred for the following reasons:
- Lifecycle data was not discoverable, and you did not need to reconcile it across multiple sources, so did not belong in the CMDB.
- Some customers need to maintain separate permissions on these attributes.
- Moving lifecycle data to AST:Attributes significantly improves CMDB performance.
Standard integration points and application forms were redesigned to accommodate this change, so customers who have upgraded to BMC Remedy ITSM 8.0 or later were not directly affected. But if your organization uses custom programs or integrations that use lifecycle data, those procedures may need to be modified to accommodate the new data structure.
Data migration resulting from an upgrade
The migration of lifecycle data to AST:Attributes happens during an upgrade from an earlier version of BMC Remedy ITSM. During upgrade, CMDB attributes are copied to AST:Attributes and a workflow is introduced to keep the data synchronized. If you want to delete CMDB attributes, run a script from the OS command line. For details, see Deleting BMC Atrium CMDB attributes copied to AST:Attributes. BMC recommends that CMDB attributes be deleted. However, ensure that deleting CMDB attributes does not interfere with your integrations or customizations.
Refer to the following topics understand the impact of this change and to evaluate whether you need to modify your customizations to accommodate the change.
