-- NAME: LFSDIAG.SQL
-- ------------------------------------------------------------------------
-- AUTHOR: - Oracle Support Services
-- ------------------------------------------------------------------------
-- PURPOSE:
-- This script is intended to provide a user friendly guide to troubleshoot
-- log file sync waits. The script will look at important parameters involved
-- in log file sync waits, log file sync wait histogram data, and the script
-- will look at the worst average log file sync times in the active session
-- history data and AWR data and dump information to help determine why those
-- times were the highest. The script will create a file called
-- lfsdiag_<timestamp>.out in your local directory.
-- value for optimizer_features_enable may be modified as needed (4/19/18)

PROMPT
PROMPT IMPORTANT PARAMETERS RELATING TO LOG FILE SYNC WAITS:
column name format a40 wra
column value format a40 wra
select inst_id, name, value from gv$parameter
where ((value is not null and name like '%log_archive%') or
name like '%commit%' or name like '%event=%' or name like '%lgwr%')
and name not in (select name from gv$parameter where (name like '%log_archive_dest_state%'
and value = 'enable') or name = 'log_archive_format')
order by 1,2,3;
PROMPT
PROMPT V$LOG OUTPUT
PROMPT
PROMPT APPROACH: Review redolog size and members
select inst_id, group#, thread#, sequence#, bytes, status, first_change#
from gv$log
order by first_change#;
PROMPT
PROMPT ASH THRESHOLD...
PROMPT
PROMPT This will be the threshold in milliseconds for average log file sync
PROMPT times. This will be used for the next queries to look for the worst
PROMPT 'log file sync' minutes. Any minutes that have an average log file
PROMPT sync time greater than the threshold will be analyzed further.
column threshold_in_ms new_value threshold format 999999999.999
select min(threshold_in_ms) threshold_in_ms

from gv$active_session_history
where event = 'log file sync'
group by inst_id,to_char(sample_time,'Mondd_hh24mi')
order by 3 desc)
where rownum <= 10;
PROMPT
PROMPT ASH WORST MINUTES FOR LOG FILE SYNC WAITS:
PROMPT
PROMPT APPROACH: These are the minutes where the avg log file sync time
PROMPT was the highest (in milliseconds).
PROMPT
PROMPT Note that TOTAL_WAIT_TIME and AVG_TIME_WAITED do not accurately
PROMPT show total time or average time spent waiting in the database
PROMPT as ASH does not sample all waits. This is simply to look for
PROMPT potential problem timeframes.
column minute format a12 tru
column event format a30 tru
column program format a40 tru
column total_wait_time format 999999999999.999
column avg_time_waited format 999999999999.999
select to_char(sample_time,'Mondd_hh24mi') minute, inst_id, event,

PROMPT
PROMPT ASH LFS BACKGROUND PROCESS WAITS DURING WORST MINUTES:
PROMPT
PROMPT APPROACH: What is LGWR doing when 'log file sync' waits
PROMPT are happening? LMS info may be relevent for broadcast
PROMPT on commit and LNS data may be relevant for dataguard.
PROMPT
PROMPT Note that TOTAL_WAIT_TIME and AVG_TIME_WAITED do not accurately
PROMPT show total time or average time spent waiting in the database
PROMPT as ASH does not sample all waits. This is simply to look for
PROMPT potential problem timeframes.

PROMPT by looking at "wait_time_milli". Look at the high wait times then
PROMPT see if you can correlate those with other related wait events.

PROMPT is doing during each 'bad' snap. Most likely you will want to
PROMPT note the times of the high log file sync waits, look at what
PROMPT LGWR is doing at those times, and go from there...

ASH THRESHOLD...
This will be the threshold in milliseconds for average log file sync
times. This will be used for the next queries to look for the worst
'log file sync' minutes. Any minutes that have an average log file
sync time greater than the threshold will be analyzed further.
THRESHOLD_IN_MS
---------------
ASH WORST MINUTES FOR LOG FILE SYNC WAITS:
APPROACH: These are the minutes where the avg log file sync time
was the highest (in milliseconds).
Note that TOTAL_WAIT_TIME and AVG_TIME_WAITED do not accurately
show total time or average time spent waiting in the database
as ASH does not sample all waits. This is simply to look for
potential problem timeframes.

ASH LFS BACKGROUND PROCESS WAITS DURING WORST MINUTES:
APPROACH: What is LGWR doing when 'log file sync' waits
are happening? LMS info may be relevent for broadcast
on commit and LNS data may be relevant for dataguard.
Note that TOTAL_WAIT_TIME and AVG_TIME_WAITED do not accurately
show total time or average time spent waiting in the database
as ASH does not sample all waits. This is simply to look for
potential problem timeframes.
If more details are needed see the ASH DETAILS FOR WORST
MINUTES section at the bottom of the report.

HISTOGRAM DATA FOR LFS AND OTHER RELATED WAITS:
APPROACH: Look at the wait distribution for log file sync waits
by looking at "wait_time_milli". Look at the high wait times then
see if you can correlate those with other related wait events.

AWR HISTOGRAM DATA FOR LFS AND OTHER RELATED WAITS FOR WORST LFS AWRs:
Note: This query won't work on 10.2 - ORA-942
APPROACH: Look at the wait distribution for log file sync waits
by looking at "wait_time_milli". Look at the high wait times then
see if you can correlate those with other related wait events.

APPROACH: If you cannot determine the problem from the data
above, you may need to look at the details of what each session

note the times of the high log file sync waits, look at what
LGWR is doing at those times, and go from there...
