SGA Sizing + OEM Issue+AWR reports
Hi Techies,
There is small application(Billing Application) running on Laptop. (Windows Vista 32 bit , RDBMS 10.2.0.3.0.)
1- We have increased the SGA_MAX_SIZE. Thought of Increase 700 M. Once we did the changes it has taken effect as 702 MB Allocated to SGA_MAX_SIZE. The same thing happened, while changing the SGA_TARGET Parameter.(After changed the parameter, it has added up 2MB extra).May I know the reason why the 2MB has added while changing the parameter.
2- OEM is not working , When it prompting for the Host User name and password, it won't accept the username and passowrd which I am used to Login into the Laptop.
3- After the generated the AWR reports, how to approach the finding , though it has many more data . Please help
Thanks,
Tippu
Hi
If you're looking to performance tune your database, run the AWR report - preferably starting and ending at snapshots during which times there was a fair amount of activity, then post the section 'Top 5 Timed Events' here and I will point you in the right direction :-)
If OEM is still not working, you can manually take snapshots and generate AWR reports from sqlplus.
Take a manual snapshot:
BEGIN
DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT ();
END;
Produce an AWR report:

Steps to generate AWR report from Oracle 11g OEM
I have gone through online documentation for generating an AWR report from Oracle 11g OEM but the documentation is more focused on generating the AWR report manually. I would request if there is a link or documentation to go through for generating AWR report from Oracle 11g enterprise manager.
I hope my question is clear.
Please revert with the reply to my query.
RegardsHI ,
Please check following link: Siva Oracle: How to generate AWR Report from OEM Grid
Thank you -
Analyzing AWR reports, how can i decide i need to increase my SGA
Hi,
I am analyzing my Production server AWR reports, how can i decide on which basis i can increase SGA.
Thanks,
MahiYou need to make sure that the corresponding memory areas are not having any waits associated with them. Changing the memory parameters is generally not an option to pick in 10g as the instance management is automatic( shouldbe) and this makes the allocations done in an optimal manner depending upon the workloads. Still the change in the parameters can be there when we see some specific wait event related to that memory area. For example, if you see lots of Shared Pool latch contention and you are assure that you have no duplicate sqls coming up in your system than may be you have an undersized shared pool so it can be increased.
You are using AWR.What about the recommendations from ADDM?Is there any advice coming up to change the memory components ? Did you elliminate all teh other areas which may be a problematic reason rather than a low memory value for parameters?

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. -
User I/O and db file parallel read is high in AWR report
Hi,
We have one performance issue during a job execution.
From the awr report we have identified one query with a table having millions of records causing problems and then we had also fine tuned that query by changing it's code and by using the optmizer hints. It is being executed in plsql batches. After fine tuning, On the first batch execution(first 5000 records) the query is taking only 5 mins, but on the consecutive batches it is consuming more time( more than 30 mins).
From the awr report I got the statistics as
Release : 11.2.0.2.0
Instance Efficiency Percentages (Target 100%)
Buffer Nowait %: 100.00 Redo NoWait %: 100.00
Buffer Hit %: 85.44 In-memory Sort %: 99.98
Library Hit %: 99.76 Soft Parse %: 99.15
Execute to Parse %: 88.91 Latch Hit %: 100.00
Parse CPU to Parse Elapsd %: 87.32 % Non-Parse CPU: 98.65
The buffer hit % is good. On each batch execution it is taking different set of records.
Top 5 Timed Foreground Events
Event Waits Time(s) Avg wait (ms) % DB time Wait Class
db file parallel read 120,485 42,540 353 89.60 User I/O
DB CPU 3,794 7.99
db file sequential read 145,074 606 4 1.28 User I/O
db file scattered read 70,030 556 8 1.17 User I/O
direct path write temp 12,423 21 2 0.04 User I/O
So the I/O is our main concern since that query contains one table with millions of records.
Host CPU (CPUs: 24 Cores: 24 Sockets: 4)
Load Average Begin Load Average End %User %System %WIO %Idle
1.40 1.45 0.6 0.3 3.7 99.0
Load is also normal.
From the Time model statistics , sql execute elapsed time is 98.27% of db time and only 7.99% is that of DB CPU.
Memory Statistics
Begin End
Host Mem (MB): 64,318.0 64,318.0
SGA use (MB): 30,720.0 30,720.0
PGA use (MB): 488.2 497.1
% Host Mem used for SGA+PGA: 48.52 48.54
Both the size of sga_max_size and sga_target are 32,212,254,720(32gb) bytes and that of
pga_aggregate target is 629,145,600(600mb)
from this it is evident that the memory is still available(so increase in memory size is not an option).
The sql statistics for that query shows like that
Elapsed Time (s) Executions Elapsed Time per Exec (s) %Total %CPU %IO SQL Id SQL Text
44,950.03 55 817.27 94.67 6.99 94.72 79dgmrxh4kv74 SELECT /*+ index(cdr_data cdr_...
I can't understand whether the problem is in the database side or with the query?
If the problem is with the query, then how it has been executed in 5 mins for the first batch ?
(all the batches are having 5000 records each).
And how can we reduce the db file parallel read ?
Your valuable advice will be greatly appreciated.
Thanks in advance
Manoj Kumar N"db file parallel read" is likely to be associated with something like index prefetching.

Tune the SQL.
Review the execution plan.
Check whether the statistics are accurate.
Review whether the index hint (and others that we can't see) is appropriate. -

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?

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

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.

Shell script for Automatic Awr Report
Hi Good Morning,
I have a requirement to generate the AWR report daily between (10AM - 06PM , 10AM - 01PM , 01PM - 10PM) . I have the below script for this .

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 sameHi,
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.

Hi,
I have doubts in Report Summary scection in AWR report.Please anyone clear it.
1,What is W/A MB processed?
2,What is the difference between logons in load profile section and Sessions in snap info section?
Logons means connection which may one or more sessions.Is it right?
3,What is the difference between Block changes and Physcical writes in load profile section?
a,,Block changes means only datafile? or including Undo/Temp?
b,Physical writes:Number of physical writes performed.What does mean?
For Ex:
1,Emp table has 5000 rows on 50 blocks.
2,Insert into emp select * from emp;Then commit;
50 blocks changed Hence the value 50 added to Block changes.Is it right?
What about Physical writes?How the writes value calculated.Just assume 100 writes performed for this insert statment.
How is the value(100) cacluated?What basis?Is there any parameter influenced?like db_block_size .....If it's what are the parameters?
4,Execute to Parse %: Parse once execute many.
Softparse %:
Buffer Nowait %: 99.97 Redo NoWait %: 100.00
Buffer Hit %: 99.93 In-memory Sort %: 100.00
Library Hit %: 103.53 Soft Parse %: 94.67
Execute to Parse %: 100.00 Latch Hit %: 94.42
Parse CPU to Parse Elapsd %: 12.94 % Non-Parse CPU: 99.81
a,Soft Parse %: 94.67.So Remaining 5.23% is hard parse?
b,If Execute to Parse % is 70,What does mean of remaning 30%?(Same statement but differ in various reason like authentication or optimizer)Is it right?
c,How to relate Execute to Parse %: with Soft Parse %:?
d,How to relate Parse CPU to Parse Elapsd %: with % Non-Parse CPU:?
5,Shared Pool Statistics
Begin End
Memory Usage %: 26.26 25.90
% SQL with executions>1: 98.95 98.31
% Memory for SQL w/exec>1: 97.79 99.46
a,What does mean of Memory usage?26.26% memory used in allocated total SGA(if configured sga_target or memory_target).Is it right?
b,at does mean SQL with executions>1?How to/Where to realet with other parameter in AWR?
c,at does mean % Memory for SQL w/exec>1?How to/Where to realet with other parameter in AWR?
6,What does mean of Per exec, per call in load profile section for the attribute DB Time(s),DB CPU(s)?
7,What is Load average begin/end in host cpu section?How is the value calcuated?
8,What is %wio in in host cpu section?
9,What does mean %total cpu and %busy cpu in instance cpu?
10,what does mean Applied urec?

RajHi,
Thanks for your Reply..........
Now we use 11g only,Not 12c.
I read oracle 11g document already(few times).But i couldn't understand it.Hence,i posted here.
If anyone tell,it is a BIG release from headache.

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.

ADDM and AWR report interpretation
Hi,
I have some confusion regarding the understanding of ADDM and AWR report.
I have created AWR reports for various period. All report indicated that all Instance efficiency checklists at their high 90s.
I have also created ADDM report during the same intervals. ADDM reports suggesting a higher SGA value.
When I am trying to correlate the ADDM and AWR then the findings seems self contradictory. On one hand AWR reflecting high instance efficiency ratios and on the other ADDM suggesting for higher SGA value. Please help me to get a better idea regarding this.
There is one more confusion. Due to some product related compulsion we have to use CURSOR_SHARING=EXACT. But the AWR report reflects 98 against Soft Parse %. Though we are using high number of bind variable within our application. But due to the value of CURSOR_SHARING all queries should be hard parsed each time the literal change. As per my understanding there should be very less soft parsing, but the value reflects high Soft Parse.
Thanks in advance for your valuable time.
Regards,
Joy>
Just a little detail to add to Dom's comments.
If you are convinced that you have lots of code that should be doing hard parsing, but the "soft parse ratio" looks wrong, then take a look in the statspack/AWR section labelled "SQL ordered by Parse Calls". You may find that some trivial, harmless looking piece of SQL has suffered a huge number of parse calls - and if so they will almost certainly have been "soft" parse calls and could therefore be hiding your expected "hard" parse figures.
Critical point: if you look at a ratio, you've hidden the underlying scale of any potential problem.
