chbl

Changes a UCM baseline

APPLICABILITY

ClearCase UCM (cleartool subcommand)

SYNOPSIS

chbl [ -c·omment comment | -cfi·le comment-file-pname |-cq·uery | -cqe·ach | -nc·omment ]

{ [ -inc·remental | -fu·ll ] [ -level promotion-level ] }
baseline-selector ...

DESCRIPTION

The chbl command modifies one or more UCM baselines. You can modify a baseline's labeling status or assign a new promotion level to a baseline.

Baseline Labels

Baselines can be unlabeled, incrementally labeled, or fully labeled. Only labeled baselines can be used to configure other streams (by using the rebase operation or mkstream).

You can change the labeling status for a baseline to incremental or full with the following options:

• -incremental, which labels versions of elements that have changed since the last full baseline was created. The newer versions are labeled.
• -full, which creates a baseline by selecting and labeling a version of each element below a component's root directory.

Promotion Levels

Promotion levels must be defined in the baseline's project VOB, before they can applied to baselines. See the setplevel reference page for information on promotion levels.

The promotion levels available in a VOB can be listed by running the describe command on the UCM project VOB object.

PERMISSIONS AND LOCKS

Permissions Checking: You must be the owner of the baseline, the project VOB owner, or a member of the ClearCase group.

Locks: An error occurs if there are locks on any of the following objects: the UCM project VOB or the baseline.

Mastership: The baseline must be locally mastered.

OPTIONS AND ARGUMENTS

EVENT RECORDS AND COMMENTS. Default: Creates one or more event records, with commenting controlled by your .clearcase_profile file (default: -nc). See CUSTOMIZING COMMENT HANDLING in the comments reference page. Comments can be edited with chevent.

-c·omment comment | -cfi·le comment-file-pname |-cq·uery | -cqe·ach | -nc·omment

Overrides the default with the option you specify. See the comments reference page.

CHANGING A BASELINE'S LABELING STATUS. Default: None.

-inc·remental

Changes the labeling status for a component's baseline from unlabeled to incremental.

-fu·ll

Changes the labeling status for a baseline from incremental to full.

ASSIGNING PROMOTION LEVELS. Default: No change in promotion level.

-level promotion-level

Sets the promotion level for the specified baselines. The specified promotion level must defined in the baseline's project VOB.

SPECIFYING THE BASELINE.

baseline-selector ...

Specifies one or more baselines to modify.

baseline-selector is of the form: [baseline:]baseline-name[@vob-selector] and vob is the baseline's UCM project VOB.

EXAMPLES

Examples including wildcards or quoting are written for use in cleartool interactive mode. If you use cleartool single-command mode, you may need to change the wildcards and quoting to make your command interpreter process the command appropriately.

In cleartool single-command mode, cmd-context represents the command interpreter prompt. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt. In Attache, cmd-context represents the workspace prompt.

• Change an unlabeled baseline to use incremental labels. The baseline specifier includes a VOB component, which must be the baseline's project VOB.

cmd-context chbl -incremental testbl.121@\vobs\core_projects

Begin incrementally labeling baseline "testbl.121".
Done incrementally labeling baseline "testbl.121".

• Change a baseline's promotion level and check the labeling status. The baseline specifier includes a VOB component, which must be the baseline's project VOB.

cmd-context chbl -full -level TESTED testbl.121@\vobs\core_projects

Change baseline "testbl.121".
Baseline "testbl.121" is already fully labeled.
