runs. Use the same subvolume or working directory for different runs of the same
source code if you want to measure the code coverage provided by all runs
combined.
An existing raw data file is never overwritten. If a raw data file already exists in the
subvolume or directory, the instrumented program will create an additional file with a
different name.
Run the Application
Run the application. An instrumented application will run more slowly than it would
without instrumentation.
To produce a raw data file from an application that does not ordinarily terminate, stop
the application manually.
If any errors occur during execution of the instrumented application, they are written to
a file named ZZPELOG. After execution, you should check for the existence of this file
(it is created only if errors occurred). It can be useful to HP support personnel, should
you require their assistance in determining the cause of the errors.
Verify Output
Check the default subvolume or current working directory for one or more files with
names of the form ZZPF* in the Guardian environment or the extension .dyn in the
OSS environment.
On the NonStop server, a raw data file is a type 180 binary file.
Example
See Run the Application on page 8-4.
