3. Select a file from the list or enter the file name you want to open, including its .SWA or .SPM

Merging Performance Models
As a TCM administrator or super user, you can also merge two Performance models into one model
or add transactions from one Performance model to another Performance model. This approach
is 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.
To merge Performance models:
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. Select 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 that is currently open:
a. Click Cancel to dismiss the Merge Performance Models dialog box.
b. Select File > Close.
c. Select 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 select All Transactions, the Merge Configuration dialog box appears. Accept the defaults
or make any desired changes. Then click OK.
TCM merges the Performance models and displays the newly merged model.
If you chose Selected Transaction, the Merge Transaction List dialog box appears.
Specify the transaction to merge from the Merge Transaction list and click OK.
9. The Merge Configuration dialog box appears. Accept the defaults or make any desired
changes and then click OK.
TCM merges the Performance models and displays the Capacity Baseline–Plan of the merged
model.
For more information, see “Merge Performance Models” (page 168).
Modifying Apportioned Data Using an .AWA File in the Current Session
If you already have apportioned data but decide you want to modify the apportionment method,
you can modify the Apportionment Weights table of an existing model or replace it with a new
table. You must be a TCM administrator to modify apportioned data.
To modify apportioned data using an .AWA file that is in your current session:
1. Open a WA model.
2. Make sure you are logged on as an administrator or super user.
3. Select Find > Apportionment Weights.
If you have more than one .AWA file in the current session, the Find Apportionment Tables
dialog box displays the available files.
4. Select the desired .AWA file, and then click Find.
