The following terms are used in CMDB-MDR integration:
A management data repository (MDR) represents software or data that contains source information about a CI. An MDR generally contains more unrefined CI information than the CMDB, which contains a managed subset of that data.
An MDR class (MDR_CLASS) is used to group MDRs that are processed similarly by CA CMDB. There are three special MDR classes: COHESION, GLOBAL, and cmdbf.
An MDR name (MDR_NAME) is the name that an MDR uses to reference itself. Verify that the mdr_name and mdr_class value combination must be unique within your enterprise.
A Federated asset ID (FEDERATED_ASSET_ID) is a unique MDR identifier for a CI.
Different CI families typically use different respective MDRs as data providers. However, a single CI can have multiple MDR data providers. For example:
|
CI Family |
MDR_CLASS |
|---|---|
|
Contact |
human resources system telephone directory single sign-on authentication system |
|
Document |
document management system |
|
Air Conditioning |
document management system contract management system air conditioning control system |
|
Mainframe |
tape management system DASD management system performance management system job scheduler |
|
Storage |
storage management system asset management system |
|
Location |
asset management system education calendar office directory |
|
Network |
network management systems problem management system |
There can be multiple MDRs in each MDR class, and each MDR can contribute data to multiple CIs. A given CI can receive data from zero or more MDRs. A CI also can have data contributed to it independently. For example, one mainframe CI may have data which was donated by Disk Management System 1, while another mainframe CI can have data donated by Disk Management System 2 and Job Scheduler 2. CA CMDB manages the relationships among CIs and all their related MDRs.
