Is there any way to get the amount of redo generated in last 2 hour. which has below chareteistic
1. redo generated by currently connected session from last 2 hour.
2. redo generated by session disconnected during last 2 hour.
total_redo = disconnected sessoin during last 2 hour + connected session generating redo during last 2 hour.
As we know that, MV is generating more redo logs during the FAST refresh. but i need more clarifications on that.
see the below examples:
exec dbms_mview.REFRESH ( LIST => 'mv_test', method=>'F');
PL/SQL procedure successfully completed.
select a.name, b.value
from v$statname a, v$mystat b
where a.statistic# = b.statistic#
and a.name = 'redo size';
NAME VALUE
---------------------------------------------------------------- ----------
redo size 147144
see the redo size is 147144 bytes. Immediately, i refreshed in MV view. now there is no update or insert or delete stats happened in source tables. but i do see redo log generation is high for NO DATA refresh.
select a.name, b.value-147144
from v$statname a, v$mystat b
where a.statistic# = b.statistic#
and a.name = 'redo size';
NAME VALUE
---------------------------------------------------------------- ----------
redo size 42352
For no rows refresh, it takes 42352 bytes.. why oracle generated redo logs when there is no DML operations happened in source table.
I need to calculate the redo log volume generated by certain tables. If I have 100 tables in the database I need to know only 25 tables redolog vloume per day. How I can calculate this , Is the log miner useful on this issue.

how to extract hour part from a date?
suppose my date is like
29-mar-2004 09:20:34
i wanna get only hour from the above date-
i want to convert minutes that is 90 want to convert it in hours and minute that format should come in 01:30 format.
can i get in this format?
in the awr report I saw some segments in Segments by ITL Waits section. Number of waits reaches to 100 in 8-hour snapshot. Is it small/big number? Should I consider increase INITRANS or there is nothing to be worried because value 80-100 are not too high?
View 3 Replies View RelatedI have an Oracle application that deals with a 29 hour clock. so the days begin at 5am instead of midnight. I am trying to get data from a table where time is up to certain number of hours, but when it reached the 00 clock my whole query returns no records, even though there is plenty of records before the midnight hour, because the data is saved as lets say 2530 instead of 0130
I am using this
SELECT *
FROM WORK.WORK_UNIT
WHERE (to_char (current_garage) = :entry_blk.curr_garage
OR 'all' = :entry_blk.curr_garage)
AND route >= 0 AND run >= 0
AND ((package_id > 0 and work_code = 99) OR
(package_id is null and work_code = 1))
and Nvl (Emp_No, 0) = 0
AND work_date = :entry_blk.p_work_date
AND on_time <= TO_CHAR(SYSDATE + :Entry_Blk.up_to_hour/24, 'HH24MI')
since oracle deals with a 24hour clock, my code doesn't seem to work if there is data for after midnight (00 hour). I am using :Entry_Blk.up_to_hour/24 to determine up to how many hours I want to see data, i.e.
on_time <= TO_CHAR(SYSDATE + 2/24, 'HH24MI')
will give me data up to 2 hours
I'm looking for a way to say if a time range includes a specific hour.
If I was looking to work out if 01:00 to 04:00 includes 02:00, then this works:
CASE WHEN TO_DATE('02:00','HH24:MI') BETWEEN TO_DATE('01:00','HH24:MI') AND TO_DATE('04:00','HH24:MI') THEN 1 ELSE 0 END
But, if the time go over two days (with midnight in between), it doesn't work:
CASE WHEN TO_DATE('02:00','HH24:MI') BETWEEN TO_DATE('18:00','HH24:MI') AND TO_DATE('04:00','HH24:MI') THEN 1 ELSE 0 END
However, I need to refresh the group manually sometimes. Therefore, I cannot set the interval as sysdate+1.have tried setting the interval as follows. However, they are not correct
Quote:trunc(sysdate+1) +4/24
The next interval will show 9:25:20pm.
Quote:trunc(sysdate+1) + interval '4' hour
Incorrect syntax
I have been trying to develop a script for generating ADDM Reports every hour and save it in a directory on the server. I was able to develop a script to run the AWR Reports for every hour and save them in a directory, but I ran into troubled waters in the ADDM script.
Database Version : Oracle Database Enterprise Edition 10.2.0.3
OS : IBM AIX 5.3
I'm trying to debug the script below to generate ADDM reports on a per hour basis and save them in a folder as well as mail than to a particular entity.
########################################################################################
# Set up Oracle environment variables...
#------------------------------------------------------------------------------
export PATH=/usr/bin:/etc:/usr/sbin:/usr/ucb:/oracle/app/oracle/product/10.2.0/bin:/usr/bin/X11:/sbin:.:/oracle/app/oracle/product/10.2.0/bin
export ORACLE_HOME=/oracle/app/oracle/product/10.2.0
export ORACLE_SID=sarcotest2.ora
export ORAENV_ASK=NO
[Code].....
Initially, the script did return me an ADDM report, but the problem was that it generated the report for only a set of two snapshots (eg: 410110 and 410111). later when the snapshots advanced further, it still generated the same report for the same snapshots.
Now, it seems it have made several changes to the script in the declare and dbms_advisor section and the reports are not being generated anyway.
One problem I am facing is
ORA-13605: The specified task or object ADDM_UAT does not exist for the current user.
ORA-06512: at "SYS.PRVT_ADVISOR", line 2043
ORA-06512: at "SYS.DBMS_ADVISOR", line 560
ORA-06512: at line 1
It seems the task is not being generated at all in my user's schema.

But it is not returning any results because of the "having" clause.
