Regarding AWR Report

Hi,
I have created AWR report .But I can not identify excat problem of the database because it is taking more time to insert data into table.
How to identify this from AWR report?

Database insertion problem in table
Are these threads related? If yes, did you go through the suggestions in that thread?

Need help on Awr Report

It's hard to present AWR report content here as if i go for copy paste the content alinment and format get changed. Is there any better way to present AWR report in my query.
Here is my query.
In a 2 hour AWR reports for a database I can see the below top 5 wait event's
the database is running on high CPU consumption (there are very less physical reads on database and Logical read is high i suppose ) so I also gather the Segments by Logical Reads. Please provide any suggestion how can i avoid logical reads I/o for the dataabse. If you see at bottom only two segments are responsible for high logical reads.
Please let me know if more content of AWR report is required.

In a 2 hour AWR reports for a database I can see the below top 5 wait event's
Comment: 2 hour is a too big interval to draw any conclusion. It should be 15-30 mins maximum.
Apart from that: 88 percent of the wall time is devoted to CPU, so do you have a problem? Not at all!!! Your database is doing pretty nothing.
the database is running on high CPU consumption (there are very less physical reads on database and Logical read is high i suppose ) so I also gather the Segments by Logical Reads. Please provide any suggestion how can i avoid logical reads I/o for the dataabse. If you see at bottom only two segments are responsible for high logical reads.
Comment: the database is not running on high CPU consumption. You would need to run an ADDM report to be able to ascertain that. We have no data on the CPU load of the server, nor how much Oracle is contributing to the load.
You cannot avoid logical read I/O, other than just stopping the application. You can tune them by tuning statements.
In the future, please wrap the output in tags (no spaces, lowercase), or I will need new glasses ;)

How to Understand AWR Report

Hi
How to understand AWR report?

Hi,
first of all, you need to understand things that this report is about -- like wait events, DB time, CPU time, etc. If you are familiar with these things, the rest is easy.
There are also some articles about reading AWR reports in my blog, including some examples: http://savvinov.com/awr/

AWR reports DBMS_ALERT_INFO queries using significant elapsed time

Hi
10.1.0.3 / OpenVMS 8.2
Has anyone encountered AWR reporting significant resource consumption on queries relating to DBMS_ALERT_INFO (via calls to dbms_alert.register)? The buffer busy waits % from AWR is high as well (see AWR snippets below). Oracle are suggesting this is "expected behaviour for the objects owned by
the SYS user".
The query takes (on average) 2.3 seconds elapsed, using 1.63 CPU seconds and is responsible for 94% of all Buffer Busy Waits.

Closing this thread even if it's not answered...Sorry, I don't have time to test this myself now, but you shouldn't mark this thread as answered if it is not, because other people might find it and think they find an answer if they have a similar question.
I suggest you try the following to narrow down things:
1. Open the RAW trace file and check the cursor numbers of the "direct path reads" - check if you can find any references for those cursor numbers manually. The cursor numbers are those numbers behind the WAIT #<xx>, and you can check if you find any other entry unequal to WAIT #<xx> with the same #<xx>, for example EXEC #<xx> or FETCH #<xx>
A short primer on how to interpret the raw trace file can also be found in MOS document 39817.1
2. Run the RAW trace file through alternative free trace file analyzers like SQLDeveloper (yes it can process raw trace files), OraSRP or Christian Antognini's TVD$XTAT. If you have My Oracle Support access you can also try Oracle's own extended Trace Analyzer (TRCA / TRCANLZR). See MOS Note 224270.1
Check if these tools tell you more about your specific wait event and oddities with the trace file in general.

How to find problematic quries using AWR report

Hi All,
Somebody please help me how do I analyze the AWR report to find out problematic quires and the relevant recommendation for it.
It would be highly appreciable
Kind Regards
Shankar

if youre running AWR means you got enterprise edition with the diagnostic licence pack add on. Substantial investment even in a minimal cpu configuration.
Reason Im asking is your question is opened ended. Sure you can look at the top consuming SQL statement, but that not might be what needs tuning so you want to waste your time trying to fix things that arent broken?
Have you got a DBA on site?

Just saw this in an oracle note regarding the mmon process suspending message (this might be due to our DB's heavy usage)
ORA-12751 cpu time or run time policy violation [ID 761298.1]
If the system is so over-loaded that it takes over 15 minutes to gather statistics or other MMON tasks, this error is expected.It is a functionality enhancement in 11g, as it prevents MMON from locking resources those other processes might be waiting for. In 10g , mmon slaves are allowed to run indefinitely.
This is at database level, as many users are in contention for resources when load is high. This is a new code that will kill the MMON slave if it takes too long to complete so that normal sessions do not have
to wait for these resources.
Solution
If the load on the system is extremely high, this is expected, and error can be ignored.

Automatic generation of AWR reports

Hi,
How to schedule the automatic JOB to generate the AWR reports hourly basis. ( automatic comparing between 2 snapshots and then generate the text file).
Thanks in advance.

Hi,
If you want the report to be send to your mail through the ORACLE ENTERPRISE MANAGER than you have to write one perl script like below: Adjust statements and addresses as per your requirement.
The main views are:
dba_hist_snapshot & dba_hist_thread which are helping us in doing this.
Hope I answered your question

Generate AWR Report automatically every day

Hi Friends,
I would like to generate AWR Report automatically every day. How do i do it.
The Start Time will be 00:00 of Previous day and the end Time will be : 00:00 of current day. The File format is html.
Currently i am using awrrpt.sql to generate report manually and i would like to achieve it automatically,I am not sure how to pass the values of start and end time (From which table i can get the values)?
Regards,
DB

Hi, DB.
You may use the below sql script , the sql script generates the AWR report for the duration of 2 days in HTML.
So you change
1) the where condition as per your requirement,
2) report name in sql script,
3) and convert it as shell or bat script based on your environment, and schedule it in your OS job scheduler / crontab.

Automation of AWR report.

Hi All,
I want to automate for awr report generating for every 30 min. For this I am creating a script which is not working properly. Script given below.
1. Declaring an variable
2. Giving value to the variable by running sql query
3. Executing dbms_workload_repository procedure.
Please help me proper steps.
SET SERVEROUTPUT ON
Declare
DBID_NUM NUMBER;
INST_NUMBER NUMBER;
MAX_SNAP_ID NUMBER;
MIN_SNAP_ID NUMBER;
DBID_NUM := select DBID into DBID_NUM from dba_hist_snapshot WHERE ROWNUM=1;
INS_NUMBER := select INSTANCE_NUMBER into INST_NUMBER from dba_hist_snapshot WHERE ROWNUM=1;
MAX_SNAP_ID := select MAX(SNAP_ID) into MAX_SNAP_ID from dba_hist_snapshot;
MIN_SNAP_ID =: select MAX(SNAP_ID)-1 into MIN_SNAP_ID from dba_hist_snapshot;
Begin
SELECT output FROM TABLE (dbms_workload_repository.awr_report_html(DBID_NUM,INST_NUMBER,MAX_SNAP_ID,MIN_SNAP_ID));
End;

Hi,
I am trying to help, however it's hard because you haven't clarified your end goal. What time period do you need to generate the AWR report for? Generating an AWR report from the entire range of available snap_id's is utterly useless. It's like measuring your average body temperature from the moment of birth up to now.
How are you planning to generate it -- into a database table, into a file, to terminal output? You didn't mention that and it's impossible to deduce it from your script.
Most importantly, why do you need to produce all these AWR reports for each 30 mins? Every 30 days, I would understand, but every 30 mins?! Do you realize that if you want to look at some trends, it much easier to do that using AWR views directly, rather than trying to extract data from html codes? And if you want your performance history just in case -- why don't you increase your SYSAUX tablespace and AWR retention, so that you can go back and generate a retrospective AWR report when needed?
I wrote an anonymous to autogenerate an AWR report for the last snapshot and dump it to the screen, hope this helps:
declare
l_dbid number;
l_inst_id number;
l_last_snap_id number;
l_output clob;
begin
select dbid into l_dbid from v$database;
select instance_number into l_inst_id from v$instance;
select max(snap_id) into l_last_snap_id from dba_hist_snapshot;
for rec in (select * from table(dbms_workload_repository.awr_report_text(l_dbid,l_inst_id, l_last_snap_id - 1, l_last_snap_id))) loop
dbms_output.put_line(rec.output);
end loop;
end;
/Best regards,
Nikolay
