DCML/ITIL/CMDB Use Cases
Ajay Gummadi
DCML
Problem
• Software Vendor VendorCo, requests for
an audit of Customer CustomerCo usage
of its server based application ServApp.
• VendorCo claims that CustomerCo
currently uses more licenses than
purchased and hence should purchase
more licenses.
• Use Case UC002 at
http://dcml.blogspot.com/
DCML
CustomerCo
• CIO of CustomerCo is IT/best-practices
savvy
• CIO has implemented DCML and ITIL in
the organization over a year ago
• CMDB reflects the current state of the
organization

Step 1
• VendorCo requests an audit
• Requests a list of all instances of ServApp,
running on BSD
• Request made via DCML DIX format.
DCML
Sample Request
<dcml version=“1.0”>
<action>audit_request</action>
<message_id>1234</message_id>
<requestor>VendorCo</requestor>
<vendor_id>10032</vendor_id> <!– used for identification 
<request_date>March 23, 2005</request-date>
<respond_by_date>March 31, 2005</respond_by_date>
<application>
<application_name>ServApp<application_name>
<application_name/>
<version>6.2</version>
<application_platform>BSD</application_platform>
</application> <!– One or more instances of application 
</dcml>
DCML
Sample Response
• Message checksum checked
• Request acknowledged
<dcml version=“1.0”>
<action>request_acknowledgement</action>
<message_id>1234</message_id>
<sender>CustomerCo</sender>
<vendor_id>10032</vendor_id> <!– used for
identification 
</dcml>
DCML
Step 2: Audit Initiated
• DCML Processor generates query for
CMDB
<dcml version=“1.0”>
<message_id>312</message_id>
<type>cmdb_query</type>
<query>list</type>
</dcml>
DCML
Step 3: CMDB Response
<dcml version=“1.0”>
<message_id>435</message_id>
<request_id>312</request_id>

DCML
Step 8: Verification of keys
• DCML Processor verifies each license key
against CMDB and DSL
• License keys are also checked against
invoices and receipts (available via
CMDB)
• DCML Processor seeks clarification from
DCML agents and users via DCML DIX
and auto-generated XUL/XForms forms
• CMDB is updated, with findings.
DCML
Step 9: Completion of Audit
• DCML Processor generates audit reports
• Internal workflow engine routes report to
CIO for approval and digital signatures
• Approved report is dispatched to
VendorCo, in DIX format.
DCML
Step 10: Post Audit Assessment
• CIO has data regarding ServApp usage
• CIO can negotiate better pricing for
licenses, using data available from
DCML/CMDB
• CIO can reallocate unused/sparingly used
licenses.
• CIO can minimize/eliminate upgrade fees
for unused (but installed) instances.
