DCML Sample Request audit_request 1234 VendorCo <!– used for identification  March 23, 2005 March 31, 2005 ServApp 6.2 BSD <!– One or more instances of application 

DCML Sample Response Message checksum checked Request acknowledged request_acknowledgement 1234 CustomerCo <!– used for identification 

DCML Step 2: Audit Initiated DCML Processor generates query for CMDB 312 cmdb_query list

DCML Step 3: CMDB Response cmdb_query_result notebooks desktops servers network_hardware telco_hardware PIM Miscellaneous

DCML Step 4: DCML PROC. > CMDB 313 cmdb_query BSD ServApp

DCML Step 5: CMDB Response cmdb_query_result 208 Vendor string Version Language Service Pack Patch Version Build Versions Install Location IP Address License Key Serial Number Install Date Number of Uses User Name Part Of Suite Date of Last Use Install Date Number of Uses User Name Part Of Suite Date of Last Use License Key Serial Number Install Date Number of Uses User Name Part Of Suite Date of Last Use
