-- File name: ash_wait_chains.sql (v0.8)
-- Purpose: Display ASH wait chains (multi-session wait signature, a session
-- waiting for another session etc.)
--
-- Author: Tanel Poder
-- Copyright: (c) http://blog.tanelpoder.com
--
-- Usage:
-- @ash_wait_chains <grouping_cols> <filters> <fromtime> <totime>
--
-- Example:
-- @ash_wait_chains username||':'||program2||event2 session_type='FOREGROUND' sysdate-1/24 sysdate
--
-- Other:
-- This script uses only the in-memory G$ACTIVE_SESSION_HISTORY, use
-- @dash_wait_chains.sql for accessiong the DBA_HIST_ACTIVE_SESS_HISTORY archive
--
-- Oracle 10g does not have the BLOCKING_INST_ID column in ASH so you'll need
-- to comment out this column in this script. This may give you somewhat
-- incorrect results in RAC environment with global blockers.

-- Example:
-- @ashtopsum username,sql_id session_type='FOREGROUND' sysdate-1/24 sysdate
--
-- Other:
-- This script uses only the in-memory GV$ACTIVE_SESSION_HISTORY, use

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.

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 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.
