Tandem Capacity Model (TCM) Manual

Workload Apportionment Options
Use the Workload Apportionment (WA) options to apportion sample data from processoriented
to transaction-oriented information before doing what-if analysis by using the Performance model.
Demonstrate Option
When you choose the Demonstrate option, TCM displays an apportioned WA model that you can
use for practice. You can make changes in the sample model, but you cannot save the changes.
Create a New WA Model Option
When you choose the Create a New WA Model option, you create a new model from your own
CSV data. You are prompted to select the CSV data to load into the new model. You also need
to apportion the data.
Work With an Existing Model Option
When you choose Work with an Existing WA Model, you can review a WA model that was
previously created as well as the history of the model. You can also load multiple samples into an
apportioned model and create several models to be part of a model set. A model set is a group
of models that use the same apportionment method but different CSV data.
Loading TCM Models Created by Other Users
If you want to load a TCM model created by another user, do not open the workload apportionment
table (.WWA file) or the performance model (.WPM file) as you would normally do for a model
that you created.
