ClearCase is an essential part of Rational's Collaborative Lifecycle Management (CLM) strategy. A key linkage to CLM is through Change Management systems, Rational Team Concert and ClearQuest in particular. The recently introduced ClearCase Change Management Integration (CMI) brings a new level of reliability, security, flexibility and extensibility to the integration of ClearCase with Change Management providers such as ClearQuest and Rational Team Concert. The integration is configurable on a branch-by-branch basis, or, in UCM, on individual streams. CMI supports secure Common Access Card (CAC) authorization authentication at the CM provider site, and tools to repair and recover from network or user errors without impacting productivity. CMI is the next generation of ClearCase-CLM integration.

What is ClearCase CMI?
• CMI stands for Change Management Integration. It is a key touch-point with
Rational Collaborative Lifecycle Management (CLM) strategy.
• The ClearCase CMI brings a new level of reliability, security, flexibility and
extensibility to the integration of ClearCase with Change Management
providers such as ClearQuest and Rational Team Concert.
• CMI is an enhancement to ClearCase which leverages dynamically loaded
libraries to support different CM providers. It is configurable on a branch by
branch basis, or, in UCM, on individual streams.
• CMI supports secure Common Access Card (CAC) authorization at the CM
provider site, and tools to repair and recover from network or user errors
without impacting productivity.

Our In-house Use of CMI
• We rolled out CMI-based CC and RTC integration in house
with two major reasons:
– while the developers have been using the CCRC/CTE eclipse client
to associate a UCM activity with a RTC WI for change set traceability,
it is quite unnatural for command line developers (such as the
ClearCase MVFS team and the CC RE team) to use Eclipse just for
association purpose.
– leverage IHD use to test out this new feature, with different client
types, and different platforms.
• Phased roll out starting with enabling it on developer’s dev
stream.
• Some UCM streams use CC-RTC bridge (via CTE) and CC-
RTC CMI together.

• From BaseCC-CQ legacy integration
– CMI provides robust and secure integration
– You can stop maintaining perl triggers ( if you have customized )
– Migration tool is available
• From UCM-CQ legacy integration
– CMI provides robust and secure integration
– CMI provides flexible configuration
• Enabling/configuring by stream, Policy based association
• From CC-RTC bridge integration
– CMI provides stream/branch based configuration with policies
– Cleartool and native GUI supports RTC integration as well
