[20231117]完善ashtt.sql指令碼.txt

--//正好工作需要使用它,我以前以tpt ashtop.sql指令碼來修改的,好像原作者做了許多改動,在他的基礎上重新改寫ashtt.sql.
--//加入提示註解:
--     @ashttz  <grouping_cols> <filters> <fromtime> <totime> <owner> <table_name>

$ cat ashttz.sql

-- File name:   ashtop.sql v1.2
-- Purpose:     Display top ASH time (count of ASH samples) grouped by your
--              specified dimensions
--              
-- Author:      Tanel Poder
-- Copyright:   (c) http://blog.tanelpoder.com
--              
-- Usage:       
--     @ashtop <grouping_cols> <filters> <fromtime> <totime>
--     @ashttz <grouping_cols> <filters> <fromtime> <totime> <owner> <table_name>
--
-- Example:
--     @ashtop username,sql_id session_type='FOREGROUND' sysdate-1/24 sysdate
--
-- Other:
--     This script uses only the in-memory GV$ACTIVE_SESSION_HISTORY, use
--     @dashtop.sql for accessiong the DBA_HIST_ACTIVE_SESS_HISTORY archive
