What is the difference between Full baseline and Incremental baseline in Clearcase UCM?

由 我的未来我决定 提交于 2019-11-26 10:57:16
I have applied full baseline for my release. for ex. Baseline "MYProj_2.0.0.20". Then testing team found some major issue. To fix that development team has delivered few changes. After completing the build , I have applied the same baseline again "MYProj_2.0.0.20. But this time i have applied Incremental baseline. As per UCM, the baseline MYProj_2.0.0.20 was turned as MYProj_2.0.0.20.3452 (some random number at end to made it unique). Now If i consider MYProj_2.0.0.20.3452 as release baseline, Will it contain all the changes or only the changes (delta change between "MYProj_2.0.0.20" and

Evil twin problem and subtractive merge

Could anyone explain what is a Evil Twin and Subtractive merge in Clearcase? Evil Twin An Evil Twin is an element that you have removed (using rmname) and want to re-add, but it's 'evil twin' exists in previous versions of the directory. You have to remember that each element had a unique ID, so you are attempting to add an element with the same name - but with a different UID. This is not allowed. The best way to deal with an Evil Twin is to relink the newest version you can find of the existing element to the new version of the directory. You can then make a new version of the element and

Proper 'cleartool mkview' for ClearCase Snapshot view creation

由 人走茶凉 提交于 2019-11-26 10:00:21
问题 Good afternoon, Seems like I am somewhat stuck in CC-land these days, but I have one (hopefully) final question regarding proper CC-handling: When using the CC View Creation Wizard, I can create a proper Snapshot view on my machine perfectly fine, however when trying to do the same with the mkview command, it fails... Using the the view creation wizard results into the (working) following view: cleartool> lsview battjo6r_view2 battjo6r_view2 \\\\Eh40yd4c\\Views\\battjo6r_view2.vws cleartool>

ClearCase to Git migration

问题 We are working on converting our CC Vobs to GIT we have both base and UCM vobs, I have seen many topic with no clear steps. Is there any tool or steps that can keep history and branches? 回答1: No, there is no ClearCase to Git bridge, convertor or adaptor that I know of (retaining the full history, with all its events). It is best to: restrict a git repo to an UCM component (while a Vob can contain multiple component and be way too big for a Git repo to handle) add in a git repo only the last

How do I perform a recursive checkout using ClearCase?

由 血红的双手。 提交于 2019-11-26 09:39:58
问题 I want to check out all files in all subdirectories of a specified folder. (And it is painful to do this using the GUI, because there is no recursive checkout option). 回答1: Beware: ClearCase is File-centric, not repository centric (like SVN or CVS). That means it is rarely a good solution to checkout all files (and it can be fairly long with ClearCase ;) ) That being said, the question is perfectly legitimate and I would like to point out another way: open a cleartool session in the

How do I roll back a file checked in to Clearcase?

由 廉价感情. 提交于 2019-11-26 09:37:39
问题 I have a file in my Clearcase repository. I checked it out and modified it, and then checked it back in. I haven\'t done anything like make a baseline, or rebase, or deliver in my stream/view. I regret having made the changes to this file--I should have undone the checkout, in retrospect. How do I roll back the modifications? (Or undo, or revert, or whatever the correct nomenclature is.) 回答1: What is described by skwllsp can be be done in a dynamic view through the use of extended pathnames

Find local copy of files in snapshot view

由 落花浮王杯 提交于 2019-11-26 07:49:28
问题 I\'m using the ClearCase Automation Library (CAL) in a tool that helps me keep track of unintegrated changes; now I\'d like to extend the tool so I can also make checkins through it. For this feature, I need to find the local copy of a Snapshot View. While I can ask CC which View is attached to a certain directory, I cannot seem to find a function to look up the local directory for a given View; also it appears as if the most reliable method to find out whether a Snapshot View exists locally

ClearCase: Can I hijack a file in dynamic view?

由 天涯浪子 提交于 2019-11-26 07:47:29
问题 I am working in a dynamic view in Unix platform. I need to hijack a file temporarily and cancel the hijacking later. But the command chmod +w filename is not working. I get the message chmod: WARNING: can\'t change filename . I can change the read-only attribute of the file from a snapshot view in windows. Questions: Is hijacking possible in a dynamic view? If yes, how? Is there a cleartool command to cancel hijacking of a file? 回答1: One of the side-effects of a dynamic view is that ClearCase

Integration stream vs integration view in ClearCase

由 我是研究僧i 提交于 2019-11-26 07:46:41
问题 In clear case terminology, what is the difference between integration stream and integration view? Development stream and development view? More specifically, why \"joining an UCM project\" involves creating both integration and development views? If I am a developer, not an integrator, should only one view be enough? 回答1: Integration is a term used by convention to designate the first root stream of an UCM project. Each UCM project has one root stream (and potentially many sub-streams). The

Clearcase Issue [closed]

问题 I am responsible for clearcase at my project. I do not have much experience. My issue is , right now our project structure in cc is a project with PROD,PV, ST, DV streams as seen here; Link to the screenshot Now as you can see we have individual stream for each developer under DV stream. The way we deliver code up stream is one by one. Now due to changes in the management, we have to implement in such a way that PARALLEL development is possible. i.e. if there is a bug in Prod and we want to
