Start and stop the trace directory

The History Trace view (HT) provides commands to do so.

Stop the trace directory

Use the STOPDIR primary command on the HT view to close and deallocate the trace directory. Active trace logging continues. All history trace commands except STARTDIR are disabled and a new trace logging request cannot be initiated. A trace directory is required for trace logging to occur.

Start the trace directory

Use the STARTDIR primary command on the HT view to reallocate the trace directory and open it with a disposition of old. If the STARTDIR command is successful, all history trace commands are re-enabled and new trace logging requests can be initiated. If the STARTDIR command is not successful, all other history trace commands remain disabled and trace logging cannot be initiated.
