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