Tandem Capacity Model (TCM) Manual

Merge Performance Models
As a TCM administrator or superuser, you can merge two Performance models into one model or
add transactions from one Performance model to another Performance model. These features are
useful for modeling the impact of combining two applications in a single system. The models you
are merging must have the same version and the same VPROC date.
1. Select Work with an Existing Model from the “TCM Initial Menu” (page 66) and click OK.
The Open PM Model dialog box appears.
2. Choose the model to open and click OK.
The selected Performance model opens.
3. Log on as a TCM administrator or super user. For more information about this step, see
“Changing Authorization Levels” (page 69).
4. Select Update > Merge Model. The Merge Performance Models dialog box appears.
5. From the list, select the model to merge with the current Performance model.
To work with a different Performance model than the one currently open, click Cancel to close
the Merge Performance Models dialog box. Select Close from the File tab. Then select from
the TCM Initial > Work with an Existing Performance Model and open the desired model.
6. Accept the default name of merged model or type a new name (other than TCM.spm) in the
Name of the Merged Model field.
7. Click the All Transactions button to merge all transactions, or click the Selected Transaction
button to specify the transaction to merge. Then click OK.
8. If you click All Transactions, the Merge Configuration dialog box appears. Accept the defaults
or make any desired changes, and click OK. TCM merges the Performance models and
displays the newly merged model. If you click Selected Transaction, the Merge Transaction
List dialog box appears. Specify the transaction to merge from the Merge Transaction list and
