AWR Reports
Hi,
Can any one know how to pull AWR Reports for 15th day back from today.
My retention period is set to 7 days. Let me know ASAP.
Thanks
Kuldeep
sql> @?/rdbms/admin/awrrptGives you a list of available snapshots from which you can pick two with no instance shutdown between.
Of course, if you have set the (default) retention of 7 days, than it is extremely unlikely that you will see
snapshots from "15th day back from today".
That was as ASAP as I could write, by the way, and should have been obvious :-)

Diff b/w snapshot baselines and AWR reports
Hi All,
Can anyone tell what is the difference b/w snapshot baselines and AWR reports. I have gone through couple of articles and i feel both are same, however given different names.
Am I correct?
ThanksAWR report is a report comparing the pair of snapshots and thus giving you the details of what has happened between that inerval!
The baselines is that "interesting time period" which you define telling to oracle and is used by oracle to compute the sql response tiime of your db with it in the subsequent timings. So both are completely different actually!

Hi There,
We're just trying to generate a awr report for one of our databases and the report is coming out with no data.
statistics_level parameter is set to "TYPICAL"; any idea to what's going on please?
Thanks

Hello,
Just to start off on the right path I would like you to know that I am a Java developer trying to understand the AWR report. To give a quick overview of my problem :
I have built a load test framework using JMeter and trying to send SOAP requests to my weblogic server. Each of these requests are getting converted multiple Insert, Update and Merge statements and getting executed on the Oracle 10g productions grade DB server. When I run the AWR report, under the "SQL ordered by Executions (Global)" I see statements that have run for 2 billion times. The JDBC connection to the database is configured to have a maximum of 40 connections and I do not see all of them being used up. The issue now is I am NOT generating that kind of load yet. I am creating around 15000 SOAP requests in an hour and I am expecting around 1million records to hit the database. The test runs fine for a couple of hours and then the server starts failing because the database is not responding back properly. When I run the statistics query on tables "gv$session s, gv$sqlarea t, gv$process p" to get the pending sessions in the database I have seen anywhere between 30 - 62 pending sessions with a activity time of more than 300 minutes.
I am sure I am not sending in 2 billion requests from the LoadTest env that I have developed but the AWR report says so. I want to know if there is a possible reason for this behavior. The stuck threads start occurring on the Weblogic server after 30 mins I start the test. Below is the exception I got on weblogic just in case it helps

How to get AWR report in text format
Hi all,
Here we are getting AWR report in html format through OEM.I want to get AWR report in .txt format
Please help me
Thanks in advanceHi
You can use the following scripts:
- ORACLE_HOME/rdbms/admin/awrrpt.sql
- ORACLE_HOME/rdbms/admin/awrrpti.sql

How can I have a collective AWR report for RAC database in 10gR2 and 11gR1?
Plz correct me here
awrrpt.sql takes the snapshot at the instance level and incase we have 5 instances we have to take 5 awr reports for a particular period.correct???
If above is true ,any wayout to collect a single collective AWR report for RAC database which includes information on all the instances in Oracle 10g R2 or 11gR1 ?
Thanks in advance
GaganI have never come across a way for this. though I can n't say it is not there.
But I guess it may not be feasible too becuase as we know the current AWR report contains data which is specific for one instance.
Various hit ratios, top events, instance effeciency reports.... what not ..
It would be really nice to see something is a new format where it lists values from each instance in a single report.. I guess such a thing Does not exiist as of now. -

here intresting is that i also can't have the memory section view also.i trien to clear awr repositary and recreate it..bounce database,also tried taking different snap value.But does notmake any change.can u tell me why tha happening..and how can i get a good awr report.Hi there,
I have covered this in my blog entry on the subject. Check that link out for more licensing information and other resources.
The problem you are experiencing is caused by the fact that AWR is part of the DIAGNOSTIC and TUNING packs of Oracle 11g, which as of 11g is no longer a standard feature of the database but rather an optional extra which must be licensed in addition to your default Oracle Standard Edition package. In terms of the licensing, you just need to license it as an optional extra so that you will actually be using it legally, and then you can go ahead and enable it.
While it may be an additional licensed item, it is actually installed on your DB by default, but is just not enabled. So, once you have cleared the licensing issue, you will be free to enable diagnostics by setting the new database parameter, CONTROL_MANAGEMENT_PACK_ACCESS. You can do this by running the following as a dba:
<pre>alter system set control_management_pack_access="DIAGNOSTIC+TUNING" scope=both;</pre>
After running this command, your database will start accumulating diagnostic information. Note that you will need to wait until new snapshots are created in which the new diagnostic information will be available. I found that although most of the information became available after setting CONTROL_MANAGEMENT_PACK_ACCESS, it was only once the database was restarted that all of the information became available. I have seen many people reporting similar behavior.
Old snapshots will obviously continue to give the errors because they did not have the diagnostic information available at the time. -
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? -
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.

balvindarIn 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 ;)

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.

Need help in reviewing AWR report
Hello Friends,
I need some information on reviewing this AWR report. Can you please tell me if you see any red flags or out of the ordinary? I’m trying to look for some performance or blocking issue that may be causing a process to run for longer than expected time or eventually terminate without finishing.
C:\Users\SIDDHARTH\Documents\Desktop\awr_rpt_-wbprdsnap_193927_thru_193952.htm
I do appreciate your help.
Thank you,Hi Ehtiram,
Thanks for your suggestion.
I have enclosed SQL stat rpt. can you suggest me which SQL ID causing this issue.

How to do Detailed AWR Report Analysis
Hi,
Please let me Know how to do analysis AWR report and get it corrected.The best way to isolate the bottlenecks in Oracle is to analyze the top five wait events for the database and look for any external waits that might be associated with disk, CPU and network.
Oracle provide two scripts to produce workload repository reports (awrrpt.sql and awrrpti.sql). They are similar in format to the statspack reports and give the option of HTML or plain text formats. The two reports give essential the same output but the awrrpti.sql allows you to select a single instance. The reports can be generated as follows.
@$ORACLE_HOME/rdbms/admin/awrrpt.sql
@$ORACLE_HOME/rdbms/admin/awrrpti.sql
The scripts prompt you to enter the report format (html or text), the start snapshot id, the end snapshot id and the report filename. The resulting report can be opend in a browser or text editor accordingly.

How to generate AWR report by using ttStats?
Hi all,are there any links or documents to show how to use ttStats toolkit to generate a report like Oracle AWR report?
If no links or document available, could you tell me how to use it?
In fact I want to know how to do a performance analysis for my application and perform some tune.
If any other toolkits are more suitable please let me know and of course the guide that how to use them is much welcome.
Thanks.The ttStats executable can be found in the <TimesTen_home>/support directory. Before you can run the executable within a command prompt, you'll need to source the ttenv.* file in the <TimesTen_home>/bin directory.
The output of ttStats -h is as follows:
ttStats [-latchstats on|off] [-display-options] [-xml file]
[-statlevel level] <dsn or connstr>
ttStats -s[napshot] [-latchstats on|off] -xml <file> <dsn or connstr>
ttStats -report <xmlfile1> <xmlfile2> <-text|-html> <report_file>
Where parameters in <> are required, and in [] are optional.
-display-options:
This option only works in monitoring mode as
screen filtering. ttStats only displays on the
screen statistics with specified prefixes.
Available prefix options include:
-cg, -ckpt, -conn, -db, -grid, -lock, -log, -repl,
-stmt, -txn, -xla, -zz, where the naming of prefixes
conforms to naming of statistics in TimesTen
sys.systemstats table. If no display option
is specified, all statistics are displayed
by default. For example, run command
ttStats -cg -stmt dsn=TptbmData
to display only cache group and statement
related statistics.
-h[elp] Print help message and exit.
-interval <secs> Collect a set of statistics every <secs> seconds
(default=10).
Note: setting this lower can negatively impact
performance
-xml <file> Write statistics to <file> in XML format. All
statistics will be written to <file> no matter
whether they are displayed on screen or not.
For example ttStats -xml mon.xml dsn=TptbmData
and ttStats -xml mon.xml -cg dsn=TptbmData
write the same file even if the latter only
shows cache related statistics on the screen.
-snapshot One snapshot of all statistics are saved to disk
in the specified file format, then the program
exits. This option should be used together with
the -xml option.
-statlevel <level>
Set the SysStats level, this value of level only
applies to sys.systemstats table.
-report <xmlfile1> <xmlfile2> <-xml|-text|-html> <report_file>
Compare two snapshots, and generate an AWR like
report. At present, each XML file contains only
one snapshot. The difference is computed as the
absolute value of statistic value in <xmlfile2>
minus that in <xmlfile1>. The result can be
written in HTML and plain text formats. XML is
not supported as output format at present.
As an example, you can run the utility as the instance admin user by doing something like:
./ttStats -s -xml tmp.xml <DSN>
You can then open tmp.xml with a web browser and see statistics about the database.
You can also compare two previously captured snaps by doing something like:
./ttStats -report tmp1.xml tmp2.xml -html tmpReport.html -
Question about Load Average in the AWR report
Hi,
I've some database in 11.2 RAC on AIX.
I was analyzing the root causes of eviction.
Looking AWR Report before the reboot I see:
DB1
Host CPU (CPUs: 6 Cores: 3 Sockets: )
~~~~~~~~ Load Average
Begin End %User %System %WIO %Idle
4.18 12.33 60.9 12.6 1.6 26.5
Instance CPU
~~~~~~~~~~~~
% of total CPU for Instance: 27.4
% of busy CPU for Instance: 37.3
%DB time waiting for CPU - Resource Mgr: 10.6
DB2
Host CPU (CPUs: 6 Cores: 3 Sockets: )
~~~~~~~~ Load Average
Begin End %User %System %WIO %Idle
3.77 13.93 60.7 12.5 1.6 26.7
Instance CPU
~~~~~~~~~~~~
% of total CPU for Instance: 6.9
% of busy CPU for Instance: 9.5
%DB time waiting for CPU - Resource Mgr: 0.0
Do you think these value ar high?
This is vmstats at the time of reboot:

Thank youThank you Jonathan,
i'm looking ASH, 15 minutes before the crash.
I've 13% of buffer busy waits and 13% of cpu quantum
Avg Active
Event Event Class % Event Sessions
CPU + Wait for CPU CPU 59.09 0.15
buffer busy waits Concurrency 13.64 0.04
resmgr:cpu quantum Scheduler 13.64 0.04
The buffer busy waits was caused by an update of a table.
There are ETL jobs that runs every nigth.
Looking IO stats I notice a change in the use of the swap:
