You can start a comparison between the design of any entity
type, or the source code of Macros. You can carry out a comparison
in the history between two versions of an instance, or a comparison
between two instances.
Procedure
To start comparing, you must carry out the following
actions:
- In the Design Explorer view, select one
instance to compare it in the history, or two instances to compare
one with the other. You can start a design comparison from any instance.
You start a source code comparison from Macros only.
- In the contextual menu, select Compare with.
You can select one of the following comparisons:
- Each Other:
This choice
compares the two selected instances.
- Local History:
This
choice compares the selected instance with one of its versions that
are stored in the local history.
Note: To configure the size and depth
of the local history, select .
- Remote:
with one of its versions that are
stored on the server. In the Component source wizard
that opens, you must indicate where the version can be found on the
server.
This choice opens
the History view in comparison mode. Double-click
one of the versions that are displayed in this view to start comparing
it with the current version that is selected in the Design
Explorer view.
- Previous in the repository:
This choice is available if you are connected to the Rational
Team Concert server that stores the selected instances. It compares
the selected instance with
its latest version that is stored on the server.
This choice opens
the History view in comparison mode. Double-click
one of the versions that are displayed in this view to start comparing
it with the current version that is selected in the Design
Explorer view.
- Master:
This choice
is available from a subordinate instance. A subordinate instance is
an instance that has the same name as an instance in a higher project
of the design build path hierarchy. The instance in the higher project
is the master instance.
If this master instance is modified,
you must decide to copy or to ignore these modifications in the subordinate
instance. To copy the modifications, you must open the compare editor
and manually copy some or all of the modifications.
