3. On the display that appears, specify your collection parameters and click OK.

4.3.2 Creating performance data

You must create the performance data files from the data collection object before you can use

the Performance Tools for iSeries to analyze the data. You may choose to create the

performance data while collecting it. However, because of the system overhead, we

recommend that you collect the data and create the files only when you need them. Sending

a collection object to another system is considerably lighter than sending a library.

Creating performance data using a 5250 display

To create performance data by using a 5250 display, follow these steps:

1. Enter the Create Performance Data (CRTPFRDTA) command. Press F4.

2. In the Create Performance Data display (Figure 4-85), specify the values for the

parameters and press Enter to create the database files.
