What to Check in AWR Report
Hi All,
Not very much experienced in performance tunning that why need your help, i generate AWR report for different times what to check, i started with top 5 events and trying to understand the portion of the report. Can anyone help me to understand the same
In case if AWR requires for the 3 snap shot i will provide the same
Hi,
If you have a performance issue on your system look for causes of that performance issue in the AWR. eg. compare the awr report for the period with bad performance with that of a one taken when performance was good. AWR taken during bad time would have "things" that weren't in the awr taken when performance was good or have "high values" for some "things". Start from that point and drill down.
If you don't have performance issues then confirm everything is running as it shoud be. Compare several awr reports and there shoulnd't me "anything" out of the ordinary.
You can start with
Instance Efficiency Percentages (Target 100%)
Top 5 Timed Foreground Events
Time Model Statistics
There are no hard and fast rules as to how you go about interpreting an awr. It depends on type of problem you have, your system, your applicaiton, time of day etc.

In AWR report, what is "Batched IO (bound) vector count" ?
Hi All,
Oracle v11.2, Linux, 64bit.
I am looking at AWR report, in section, Instance Activity Stats.
First stat is "Batched IO (bound) vector count". What does that stand for? I tried searching in documentation.
Actually, in Instance Activity Stats, first few lines are, Batched IO (bound) vector count, Batched IO (full) vector count, Batched IO (space) vector count, Batched IO block miss count, Batched IO double miss count. Where can I find the details/meaning for these statistics ??
Thanks in advanceThis is an idle wait event. For the description of it, see below

Hi All
As below example, I have question What is measure of "Waits" value in "Wait Events" section in AWR report?
Because "Waits" value is high but "Total Wait Time (s)" is low. example "SQL*Net message from dblink" has 30,115 "Waits" but "Total Wait Time (s)" less than "db file scattered read" has 28,659 "Waits".
Could you please explain more about "Waits" value?
Thank you

Hi All
As below example, I have question What is measure of "Waits" value in "Wait Events" section in AWR report?
It's simply a count ... of the number of times the system had to "WAIT" on the specified event.
Because "Waits" value is high but "Total Wait Time (s)" is low. example "SQL*Net message from dblink" has 30,115 "Waits" but "Total Wait Time (s)" less than "db file scattered read" has 28,659 "Waits".
Look at "AVG wait time". In the one case, there were fewer occurrences of the event, but the average wait time per event was greater.
If I buy 3 hamburgers and pay $1000 each
or I buy 500 hamburgers and pay $1.00 each,
why do 3 hamburgers cost more than 500 hamburgers?
Could you please explain more about "Waits" value?
"Waits" is the number of times the system had to wait on the named event, during the sampling period.
"Total Wait Time" is the total time (measured in seconds) spent waiting on all occurrences of the specified event, during the sampling period.
"Avg" wait" is the average time (measured in milliseconds) spent on each occurrence of the specified event, during the sampling period.
It seems pretty self-evident. You count how many times something happens (waits), you measure the time spent doing that something (total wait time), and you divide the total time spent (total wait time) by the number of times it happened (waits) to find out the average time spent on each occurrence of that something.
Thank you

Updating AUD$ consumes most of the time in AWR report.
Hi All,
It's really good to see, great people passing their help to folks like us and making our life easier. Going forward,I am investigating on of the performance issue and analyzing the AWR report. By looking AWR, I did find updating aud$ taking most of times in AWR report. Following are the information , I extracted from the database and AWR report. Please see, what can be done to take away the bottlenecks.

Audit Size
2469RegardsBefore purging audit data I would suggest two things. First what is the time period for the report in question? If it is for a low usage period then the audit activity as a percentage of the overall load may be a bit distorted. It may also be worth checking to see what information the audit captured as you could have a contractual or legal obligation to capture the data.
Second and most import look to see what audit rules are in effect. By just removing a few unneeded rules such as auditing successful logins/logoffs or changing from by access to by session for specific objects you could potentially remove most of the activity being shown.
You may also want to check to see if a purge job has been set up. See dba_scheduler_jobs and Oracle proviced package: DBMS_AUDIT_MGMT.

Shared Pool Statistics - awr report -m 10.2.0.1
Hi,
I'm new to reading awr report and performance tuning.
I have the below in my statspack.
Do i need to increase my shared pool?
Any one can advise and explain "% Memory for SQL w/exec" and "% SQL with executions>1"
Shared Pool Statistics
Begin End
Memory Usage %: 95.78 97.71
% SQL with executions>1: 51.51 80.85
% Memory for SQL w/exec> 1: 67.88 82.46
thanks!user21123 wrote:
The sweet point for the shared pool Memory Usage % is at about ~70%-80% because of aging out. You are at ~90%. It would be advisable to increase the shared pool, but if you're using 10g SGA_TARGET and SGA_MAX_SIZE, then that might require increasing those parameters. It depends how your AWR report looks for the Buffer Cache.
What makes you think this ?
In an OLTP system you hope for 100% shareable SQL, and correct allocation for the other objects, which would lead to 100% usage. In realistic terms, you're likely to get a few percent (which is often the shared_pool_reserved) free because there's a constant turn-over of non-shareable SQL.
If you're always seeing 70% - 80%, then there are several scenraios that might explain the figure. One is that you've simply made shared pool a bit too big. At the opposite extreme you might be constantly flushing 20%-30% of the material from the shared pool because it has become so fragmented that you have to clear a lot of garbage to create a small amount of contiguous space.
The best guideline to follow is to check whether you appear to be losing a significant amount of time on libarary cache and shared pool latches, using up an undesirable amount of CPU on parse time, see lots of reloads (without corresponding invalidations) in v$librarycache.
Without further information, we really can't say how good or bad the situation is. In fact, it's possible that the information that +"50% of your SQL has been shared, 50% has been single use"+ is a possible indicator that the shared_pool_size is too small, and we are filling the excess space with garbage rather than keeping the garbage (and library cache search time) to a minimum.
I would be interested to hear the thinking behind your suggestion, though.

I need you help to analyze the results of the following awr report:
The following awr report is an one hour report of oracle EBS application, oracle version 10203,
on hpux with 20 cpus.
As you can see , the top wait event is on "CPU time".
I read an article by mr. lewis regarding the same issue:
http://jonathanlewis.wordpress.com/statspack-distractions/
on a machine with 20 CPUs , with one hour report , i have (3600*20)=72000 seconds to play with.
although for the one hour target we should be aiming to use less than (1*3600*20)=72,000 CPU seconds.
In my case I am using just 13,368 cpu second.
The Load averages (from hpux top command): 0.30, 0.29, 0.28 on the machine low.
Looking at "Top 5 Timed Events" shows that the last 3 wait events are not an issue.
I alreay know the reason for the db file scattered read , and fixed it.
Yet i still have a "nasty" huge plsql block (sqlid=32fwmj6fsaqm9) that run more than : 80973 sec (about 21 hour).
select last_call_et,status
from v$session
where sid= 97
LAST_CALL_ET STATUS
80973 ACTIVEThe top 3 statment that appear at top of "SQL ordered by CPU Time" are the same as
the ones on the "SQL ordered by Gets ".
Soprisely the statment that run 21 hour is not at the top of any wait event.
It just at the 8 place of the "SQL ordered by Gets ".

The last_call_et would be from the moment the front-end code called the pl/sql block, and since then the pl/sql could have been running a loop with a lot of deliberate waits (dbms_lock.sleep), or a number of different SQL statements that individually didn't consume huge resources or lose a lot of time, yet totalled a lot of time.
Simple check before you start tracing, and if the session is still alive: select * from v$session_event where sid = 97, select name, value from V$sessstat where sid = 97 and value != 0, to see what clues this gives you about the time. You never know, you may find that a lot of the time was spent waiting on "PL/SQL lock timer".

DBACockpit - Generate AWR reports not visible
Hello,
i have read the "SAP on Oracle Development Update":
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a07754d4-edd4-2910-0683-c9473aaeca51
On page page 27 is a screenshot of the possibility to generate AWR reports out of DBACOCKPIT.
I have an ABAP system on SAP_BASIS 7.00 with Patchlevel 15 (SAPKB70015) but i can not see this menu option. I only have the "Active Session History" but no "Workload Reporting".
As described in sapnote #1028068 the monitored database is a local one and the licenses are purchased by SAP. The note also describes that the function should be available with SP12.
What's wrong? Have you already checked your system for this point?
Regards
StefanHello Stefan, Hello Bill,
we had the same problem. In 7.00 SP12 you can select the option, in SP15 it is not visible. We opened a customer message and were told, that there were some irritations arount the license of Oracle Diagnostic Pack, so SAP deactivated it in DBACOCKPIT/SP15. This is no problem any longer (note 1028068).
In later SPs you can set an option (have look at note 1136582 / 1250596), but in SP15 you have to modify the source code. Unfortunately SAP isn't able to ship this via snote. In this case it might be better to open a customer message to get a detailed information.

AWR Report -- Buffer Pool Advisory
Hi,
does anyone know in that kind of measurement the "Estimated Phys Reads (thousands)" from buffer pool advisory is ?
I mean in seconds ? in hours ? addicted to the time period the report was written ?
http://img.ly/images/6379055/full
Thanks a lot
*TRe,
OK it makes it a little bit clearer.
What I now think to understand is that the "Estimated Phys Reads (thousands) no represents the
current workload of the system it only gives clue that there will be a change around 3 times more blocks was red.
Right ?
But if it is like that why these numbers are changing from one to another report....
So again another image.... Maybe my problem is that I try to set the current workload (phys block reads) in comparison with the "Estimated Phy Reads from the Advisory....
Our AWR reports are generated every hour.
http://img.ly/qNfn
Sorry for my understanding problem... I also will try to check if the views gave other information than the ARW report.

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!

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. -
Hi, friends ..
I am using Oracle 11g standars edition(11.2.0.1.0) on solaris 10 platform.I do have a very strange probleem..when iam trying to capture awr report i am getting a blank
awr report contain ing nothing...like below section

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. -
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.

Randolf
