Note:

The protrace collection is only available on UNIX.

Negative values produce the same output and process spawning option as the positive value, but also indicate that the event should only trigger if the error is fatal, bringing the database down.

To change this parameter while the database is running, use PROMON or the _DbParams VST.

You can use this parameter to support continuous operation of the database. For more information, see Change database parameters while the database is running.
