Finding the Latest Baseline in clearcase on which Rebase is not yet happned

Question

We have created multiple Development streams under Integration and also have one Deployment stream.
When the developer will do the changes and any one of the Dev stream and create the Baseline on Int, it automatically triggers rebase on Deploy stream, then build and deployment will happen.

The issue here is how do I know which development steam created the baseline when I have one deployment stream for rebasing against, with many Development streams for build and deployment.

Is there any command to find the latest baseline created and on which still the rebasing is not happened?

Answer 1

You have this I presume:

Int
|
-----Deployment
|
-----Dev1
|
-----Dev2
|
-----Dev3

You deliver to Int, then rebase to Deployment.

You know which baseline has just been rebased from Int (since a rebase simply replace the foundation baseline of Depl with one coming from Int) But you don't know what that baseline on Int comes from Dev.

Simplest solution: if that baseline on Int is created each time one dev baseline is delivered: naming convention.
A proper baseline name can help you remember the dev baseline it comes from.

The problem with rebase is that, once you rebase on deployment, you don't know what was the baseline present on deployment just before the rebase.
That is why, in addition of a rebase, you need to update a metadata attached to, for instance, the Deployment stream object, in order to keep a list of the rebased baselines.
See as an example cleartool mkattr illustrated in "How to update the property for all member baseline in UCM?".
