9 <h2>Dictionary file and trace activation</h2> |
|
10 <p>Trace activation is a way of generating specific trace data that is |
|
11 relevant for your components. This reduces the amount of traces listed |
|
12 on the TraceViewer user interface.</p> |
|
13 <p>All the traces that come from various components on the device are |
|
14 first passed onto a trace handler, called TraceCore. TraceCore then determines |
|
15 which traces should be handed over to the PC and which ones should not. TraceCore |
|
16 only passes on those traces that have been activated and ignores the rest. |
|
17 </p> |
|
18 <p>To activate and deactivate traces that are in the Open System Trace |
|
19 (OST) format, you must first define the used <i>Dictionary file</i>. </p> |
|
20 <p>Dictionary files are XML files that are usually available in your development |
|
21 environment. They are automatically re-generated every time Trace Compiler |
|
22 is run. This usually happens when you compile a component that contains Open |
|
23 System Trace (OST) traces. Dictionary files can normally be found from the <i> |
|
24 \epoc32\ost_dictionaries</i> directory under your Software Development Kit |
|
25 (SDK).</p> |
