PROMPT This is an experimental script as some documentation/explanation is needed.
PROMPT The ASH "delta" metrics are not tied to individual SQL_IDs or wait events,
PROMPT They are valid in the session scope (and related mostly static attributes,
PROMPT like PROGRAM, MACHINE, MODULE). Which SQL_ID/operation/event happens to be
PROMPT active when ASH samples its data is just matter of luck.
