Saving a Workload Apportionment Model
Saving a model involves saving the apportionment tables and formulas so that the model can be
used as a template for apportioning additional performance samples. Create a new model whenever
the apportionment method has been customized for a specific application (or set of applications)
for the first time or changed for an existing model.
The Save As menu item allows you to change the name of the model; the Save menu item does
not.
To save a Workload Apportionment model with its existing name:
1. Select File > Save.
2. The TCM Save dialog box appears. Select the desired option and click Continue.
• Select Workload Apportionment Model files to save everything that is open in this session.
• Select Apportionment Tables to save the apportionment tables. This option is available
only when apportionment tables are open in the current session.
• Select Capacity History to save the capacity history file. This option is available only when
a capacity history file is open in the current session.

apportionment tables file with a .WWA extension. The file is saved with a .WWA extension
in your folder. For example, in the tutorial’s Example application, the model file is named
EXAMPLE.WWA. The WA spreadsheet is saved in a file with an .SWA extension.
