RTC Source Control- How different from ClearCase ?

Change-set based SCM

– accept / deliver / suspend / resume to flow change-sets across workspaces and streams

Repository Workspace

– No “checkout” operation. Best practice is that every developer has his/her own repository workspace

Process Integration

– Access Control by team area / project area

– Pre-conditions and Follow-up actions by iteration types

– Association to Work Items, Builds

Distributed Development

– Distributed SCM for network latency

What is available only in ClearCase?

– Derived Object support / config records / build avoidance

– Dynamic view

– Multisite

– Hard-link4

ClearCase Baseline Importer

Importer available since RTC 2.0

Imports interested versions in history by label type or by UCM baseline

Leverage ClearCase Synchronizer

– Various setup requirements

Manual steps to importmultiple streams or branches

No migration of check-in credential

No migration of check-in timestamp

Both CC and RTC has to be online5

ClearCase Version Importer

• Two step importer

1. Export data from ClearCaseAll the file element versions in all branches, version properties, configurations ( label-types, views ) are extracted to intermediate files

2. Import data into RTCThe intermediate files are imported to RTC and file version histories and baselines are created in the RTC repository

RTC 4.0.5 (Q4 2013) Initial Release of the new Migration Tool

4.0.5 “ClearCase Version Importer”

– Simplified command-line tool to export/import

– Import all the file versions in all branches in single operation

• Merge hyper-links are also imported

– CC check-in user can be mapped to RTC change-set owner

– CC check-in timestamp is migrated as RTCchange-set creation date

– CC version attributes can be imported

RTC 4.0.6 (Q1 2014) ClearCase Version ImporterMake the tool more consumable & incorporate feedback

Multiple Configuration Import

– ClearCase views, label types can be imported by single operation

– They are imported as RTC baselines

Increased Robustness & consumability

– Restarting migration commands will resume the operationThis is helpful when the command fails in the middle by network glitch or scheduled outage, etc.

– Incremental Migration

• Large VOB can be migrated by sub-folders

• Additional versions can be migrated subsequently

• Additional configurations can be migrated subsequently

RTC 5.0 ( Q2 2014 ) and Future Enhancement PrioritiesMake it ready for mid&large scale deployments

Filter uninteresting versions

– As a user I would like to import only versions that are less than some number of years old (281520)

– As a user I would like to import only latest versions in selected configurations with dependency relationships (286971)

– As a user I would like to import only version from non-obseleted branches (281519)

CQ-enabled UCM migration

– Version Importer should add link from imported change-set to work items when CC and CQ are migrated together. (300055)

Performance Improvements

– [Time Boxed for 5.0] improve performance of Version Importer (299828)

Post 5.0 Consideration

– UCM Metadata migration : [CCM] Whole UCM PVOB importer (171345)

– Verification tool : Make the verification and report tool production ready (261011)

CLM 2014 Continuous Client Feedback Program/CCF Plan Program summary: The Continuous Client Feedback (CCF) Program is a new type of client program

created to support the strategy of the continuous delivery model, in place of the Beta Program used in past CLM releases.

Who are the target clients: We will leverage an extended client base for discussions of the nature that can be included on jazz.net. If the IBM team needs to discuss future topics beyond jazz.net (i.e., IBM Confidential in nature) we will leverage the clients under NDA agreement only. We will include the following clients: Existing DPP clients More practitioners from the existing DPP companies (administrator, tester, developer, business

analyst, scrum master) Previous beta clients, and new clients (with practitioners to participate)

How to facilitate feedback: IBM team needs to show clients the new features and improvements. Need to start as early as possible to get design feedback. IBM stakeholders and the clients will drive

the need for follow on discussions and reevaluate certain features after including clients’ feedback. The Jazz.net sandbox will be the milestone delivery method to clients who can’t install in their own

environments for hands on testing. Obtain client feedback on consumability & quality via hands-on testing of selected milestone(s) Conduct polls along the way, also send a short formal survey before QCert.

What is the duration of the program: Goal is to start getting clients engaged with earliest possible milestone agreed to by development team. Will end no later than 2 weeks after eGA, with additional feedback used as input to future release.

When to report feedback: Will provide small feedback report for QCert, and provide updates before the program ends.

CCF for RTC 5.0: Kick off meeting is planned for the week of March 3rd. Contact: Brian Jones ( [email protected] )
