Tandem Capacity Model (TCM) Manual

After the dialog box appears, choose the transaction to trend and optionally the start and end
dates. Then click OK. The data is modified to show the trend in the Planning Timeline model. TCM
uses a linear regression based on historical data to project the data. This option requires at least
10 Measure samples and a confidence level of 95 percent.
Calibrate Batch Response Time
The Calibrate Batch Response Time option is used to calibrate the response times for a batch
transaction to actual observed response times.
To calibrate Batch response times:
1. Open a Performance model.
2. Select Update > Calibrate Batch Response Time. The Calibrate Batch Response Time dialog
box appears.
3. Select the batch transaction name to calibrate from the list.
4. Type the observed response time in the Calibrate Batch Response Time dialog box or accept
the default values. You can enter hours, minutes, and seconds.
5. Click OK.
TCM changes the Performance model according to your observed response time instead of
TCM estimated response times.
