ClearCase wants to merge unchanged files after deliver to alternate target

阅读更多关于 ClearCase wants to merge unchanged files after deliver to alternate target

Using Rational ClearCase v. 7.0.1.1 with UCM, I have a problem here when using ClearCase's "Deliver from Stream to Alternate Target" functionality. Imagine we have one project integration stream and two developer streams A and B derived from it. Now I change a file in stream A. I want the delevoper owning stream B to be able to use my work without me having to deliver the file to the integration stream yet, so I deliver from stream A to the alternate target stream B. So far, so good. I go on making another change to the file but the stream B developer does not need this change, so I don't

What is deliverbl in UCM ClearCase?

阅读更多关于 What is deliverbl in UCM ClearCase?

问题 I am wondering about 'deliverbl', how important are they for historical purposes or during development? All I know is they are created during delivery and includes activies. If i am exporting major baselines from Clearcase to different SCM, should I consider 'deliverbl' as major baseline? 回答1: There are representing merges (from a child stream to another stream), so: they should be considered, as they show the code "merged" (with potential conflicts resolved) but you might have more trouble

Get all versions from a specific time - ClearCase UCM

阅读更多关于 Get all versions from a specific time - ClearCase UCM

问题 We are using ClearCase UCM, and someone asked me if there is a way to get all of the versions from a specific time. Example: Work is being done on a development stream. Someone broke the build, but the previous baseline is too far back and we would lose too much work. They would like to get the versions of every file that was there from last Thursday at 11:00am. Is this possible, even if it hasn't been baselined at that specific time? Is there a way to revert back to that specific time? (I

ClearCase: Is it possible to cancel checkouts not made from your own view?

阅读更多关于 ClearCase: Is it possible to cancel checkouts not made from your own view?

问题 Can the project manager force cancellation of checkouts of files/directories made in any view/stream/project? How? 回答1: A ClearCase administrator can force all files of a given view to be considered as "not checked out" (which is the equivalent of canceling their checkout status), with cleartool rmview: cleartool rmview -force -uuid (uuid_of_the_view) -vob \aVob You can get the uuid by grepping the user in the output of: cleartool descr -l vob:\aVob See technote "Removing checked-out

Clearcase UCM - Cross delivering vs. delivering upwards?

阅读更多关于 Clearcase UCM - Cross delivering vs. delivering upwards?

We have two Clearcase UCM streams in a hierarchy at the same level (i.e. same parent stream). If the two child streams are both rebased to the same parent baseline, does that mean that Delivering the activities of both streams up to the parent (one, then the other) Would be equivalent to: Delivering the activities of one child stream to the other child stream, and then simply delivering the one child stream to the parent Is this in fact true? It seems it should be, assuming any manual/user selected merges for all deliveries are made in the same way. VonC This is correct, but first a few

How to merge changes from a specific UCM activity from one ClearCase stream to another

阅读更多关于 How to merge changes from a specific UCM activity from one ClearCase stream to another

问题 This should in theory be quite simple, i.e. merge the changes from a specific UCM activity from one stream to another. I had thought that I might just be able to use the Deliver command in the GUI and then select just the required activity to deliver, but it seems that the target stream is set to not allow deliveries from other streams. From searching the documentation it seems that I might instead be able to do this via the command line using the findmerge tool, but it's not at all clear

Difference between branches and streams in ClearCase?

阅读更多关于 Difference between branches and streams in ClearCase?

问题 What is difference between branches and streams in ClearCase? 回答1: A branch is a classic versioning way to parallelize the history of versions for a given file: See "When should you branch" A Stream is not a branch : it is just a metadata able to memorize what baseline any view referencing that Stream will see. When you create a Stream, nothing happen (no branch is created). But a Stream name will be used when a file is checked out: any view will set its config spec in order to create a

Clearcase UCM is trying to merge pdf files

阅读更多关于 Clearcase UCM is trying to merge pdf files

While delivering to integration stream , Clearcase UCM is trying to merge pdf files and fails. As PDF files no need to be merged, how to solve this? Is it a defect in Clearcase UCM? any work around is there or some policy settings needs to be set to solve this? If you don't want to merge a specific type of file, you can change its type to a "copy merge" policy (ClearCase will copy the source over the destination) cleartool find . -name '*.jar' -exec 'cleartool chtype "COPY_MERGE" $CLEARCASE_XPN' This is an improvement from the NEVER_MERGE presented in this IBM article , and is available in

how to find the list activities delivered to integration stream on a particular day?

阅读更多关于 how to find the list activities delivered to integration stream on a particular day?

问题 We use to take nightly builds irrespective of any files were delivered to integration stream or not. What i would like to do is , find the list of deliveries done on a particular day. If there were no deliveries to integration stream then build will not be triggered. Through project explorer itself we can see. but i would like to know from commands. 回答1: Any deliver in UCM will generate an activity call deliver.xxx . Simply list all activities for a given Stream (see cleartool lsact man page)

What is composite baseline in UCM and when it will be used?

阅读更多关于 What is composite baseline in UCM and when it will be used?

What is Composite baseline in UCM? When it will be used? Will it be used mainly when we have multiple components? The reference on "composite Baselines" is: " Best practices for using composite baselines in UCM ". Introduced in ClearCase v2002, composite baselines are a mechanism for grouping baselines into a collection. One baseline is designated as the composite, and other baselines become members of the composite You do not necessarily have to use composite baselines when you have multiple components, but: If you want to remember the set of baselines existing at a given point on your Stream
