View 4 RepliesI am working on SQL Developer 1.5.1, i need to prepare hourly record of the activity on the database, for that i have a sql query that gives me the report as per selected columns on hourly basis.I need to prepare 24 reports a day.
Each time i have to go to the query , change the date as per hours like form 22:06:2011 10:00:00 to 22:06:2011 11:00:00 and get the report and export it in excel.
I want to automate the script so that whenever i run the script , it just asks me the date and runs the script 24 times and fetch me the hourly report of whole day.
the query syntax is something like this
Select
............................
...........................
..........................
from
..........................
........................
........................
where
And.......................
And...................
And......................
And req date between to-date( 22:06:2011 10:00:00) And to-date(22:06:2011 11:00:00)
Order by 7,1,2,3,4,5
Is there any possibility that i can automate the script to automatically change the hour itself and generate a report in excel 24 times?
I have a table which have two columns date on hourly basis and response time. I want to pull the previous date's data on hourly basis with the corresponding response time. The data will be loaded to the table every midnight.
eg: Today's date 23/10/2012
I want to pull data from 22/10/12 00 to 22/10/12 23
The below query is pulling the date as required but I am not able to pull the response time.
with a as
(select min(trunc(lhour)) as mindate, max(trunc(lhour)) as maxdate from AVG_HR)
SELECT to_char(maxdate + (level/25), 'dd/mm/yyyy hh24') as dates FROM a CONNECT BY LEVEL <= (1)*24 ;
I have a table with a date time column which actually stores the data as and when it is inserted. I need to calculate the time the machine has worked hourly wise. For example the table contains records from 13:00 to 13:15 and 13:45 to 14:00 i should get 30 mins as working time..

The sqlcache is getting over-written.I would like to capture information from AWR snapshots and feed those (as a workload) into the DBMS_ADVISOR.I can't see where it's possible (other than manually creating my workload from AWR information)
View 3 Replies View RelatedI have a table MYTABLE in database mydb1 duplicated via materialized view and materialized view log and refresh_snapshot commands to a MYTABLE on mydb2 database.
I like to duplicate this table MYTABLE to a third database mydb2, using the same method (materialized view and refresh_snapshot command).
Is it possible ? What's hapend to the materialized view log where I launch a refresh_snapshots on mydb2 ? How is this materialized view log truncated ?
How can check database performance in a non-sequential parts of a day using AWR tool. For example, suppose we divide a day to 2 parts: low-traffic time and high-traffic time with the following time interval:
low-traffic time : 7:00am - 10:00am and 7:00pm - 11:00pm
high-traffic time : 10:00am - 01:00pm and 4:00pm - 06:00pm
I want to examine performance using snapshots gathered by AWR. If I get 2 AWR reports for low-traffic time of day (one for 7:00am - 10:00am, another for 7:00pm - 11:00pm ) and compute average of values in 2 reports, could I called it database performance in low-traffic part of day or not?
Simplifying the data structure that my problem concern, let's say there are two materialized views between whose data there's a one-to-many relationship [the relationship can be logical without a need of creating any foreing keys].
The data should be as actual as possible respecting the content of the master tables, let's say it shoul be refreshed every 5 minutes.
As far as I know, the jobs related to each snapshot, even if they have a START WITH and NEXT parameter set to the same value, work independently...So: what would be the best manner to synchronize the jobs so as to make sure the data of both snapshots are coherent?
If I create an AWR Report via OEM or awrrpt.sql for an interval between two snapshots, in the report there are statements which were not executed in this interval.
Are there any known bugs for that problem or have you got an explanation for this behavior?
I have some questions about Oracle + EMC shared storage. I have Oracle 11gR1 RAC (2nodes) + ASM environment with shared shorage EMC Clariion AX4.
The database is running no archivelog mode. I'd like to implement point-in-time recovery using Snap View snapshots.
Currently my AX4 platform has the following LUNS:
LUN1 - registry 1
LUN2 - registry 2
LUN3 - vote 1
LUN4 - vote 2
LUN5 - vote 3
LUN6 - ASM - DISKGROUP DATA DISK DATA01 (actual db datafiles)
LUN7 - ASM - DISKGROUP DATA DISK DATA02 (actual db datafiles)
Using source LUNs in consistent session will take sync snapshots of all the LUNs working against my database. Once something happens with database, the LUNs can be returned to specific point in time when snapshot consistent session was taken and I'm expecting the database will up and continue to work.
Questions:
1. Is my approach correct at all? (The database is running noarchivelog mode, not dealing with hot backups. The recovery point in time implemented purely via EMC snapshot consistent sessions.)
2. The AX4 platform has a limit 8 source LUNs in session. If I understand it correctly, I can't place more than 8 LUNs in session. What will be the workaround if my database will occupy more than 8 LUNs, I'd like to take their consistent snapshot; for example:
LUN1 - registry 1
LUN2 - registry 2
LUN3 - vote 1
LUN4 - vote 2
LUN5 - vote 3
LUN6 - ASM - DISKGROUP DATA DISK DATA01 (actual db datafiles)
LUN7 - ASM - DISKGROUP DATA DISK DATA02 (actual db datafiles)
LUN8 - ASM - DISKGROUP DATA DISK DATA03 (actual db datafiles)
LUN9 - ASM - DISKGROUP DATA DISK DATA04 (actual db datafiles)

How to find out how much undo will be generated by a dml / ddl statement in Oracle 9i? With Oracle 10g we can use the famous mystat.sql and mystat2.sql with argument as 'undo change vector size'.
However with Oracle 9i there is no statname as 'undo change vector size'
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.

I have found there is a wearied of email generated from my database. I have the data base server located in US (estern time) and the sysdate in the database is AUSTRALIA (AEST). But i am working from India (IST).I have one procedure, which will send email to some recipients once the job is done. It is using UTL_SMTP for sending the email from database.
Now problem is, the email i got from this procedure has a different timestamp which is NOT matching to any of the times:
Time in Mail : 2-Nov-2012 9.56 PM
IST Time : 2-Nov-2012 10.56 AM

View 4 Replies View RelatedAs 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.
We are using the function dbms_utility.get_hash_value to create a unique identifier, the hash is created based on statement of creating an index. We see that for a different statement is being generated the same value, which in this cause errors because this value must be unique.
The Hash is to be calculated as follows HASH_VALUE = dbms_utility.get_hash_value (sql_text, a 10000)
We are using the correct the hash function or should we use another way to generate unique values?
