chbl

Changes a UCM baseline

APPLICABILITY

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 streams (see the reference pages for rebase and mkstream).

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.

RESTRICTIONS

Identities: No special identity required.

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

Mastership: The current replica must master the baseline.

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 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 an unlabeled baseline to incremental. This option has no effect if the baseline is already incrementally or fully labeled.

-fu·ll

Changes the labeling status for a baseline from unlabeled or incremental to full. This option has no effect if the baseline is already fully labeled. A chbl -full operation make take a long time for components with many elements.

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. Default: None.

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

The UNIX examples in this section are written for use in csh. If you use another shell, you may need to use different quoting and escaping conventions.

The Windows examples that include 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 UNIX shell or Windows command interpreter prompt, followed by the cleartool command. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt. In Attache, cmd-context represents the workspace prompt.

NOTE: In the UNIX examples that follow, arguments and output that show multicomponent VOB tags are not applicable to ClearCase LT, which recognizes only single-component VOB tags. In this manual, a multicomponent VOB tag is by convention a two-component VOB tag of the form /vobs/vob-tag-leaf-for example, /vobs/src. A single-component VOB tag consists of a leaf only-for example, /src. In all other respects, the examples are valid for ClearCase LT.

Change an unlabeled baseline to be incrementally labeled. 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.
