Oracle 9.2.0.8 and AWR report?
Does anyone know if 9.2.0.8 supports AWR?
Thanks in advance!
Thanks! I figured it may since I have also seen that it now support Automatic Memory Management, which was also introduced in 10g v1.
Thanks

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!

Oracles tools to generate static and interactive reports
Hi,
What kind of oracle tools can generate statis and interactive reports, is there any free one, and where to get it?

What type of reports you're looking? Performance report? you can use AWR but this is not free. You can use statspack instead
Hope this helps

Is statspack and awr report are same?
Hi
All,
Is statspack and awr report are same? and in which oracle version they are?
Thanks,
VishalI wouldn't expect AWR or statspack to be able to generate snapshots or to run reports while the database is in restricted mode. I've never tested it, but I wouldn't expect it to work.
Restricted mode is not normally used to allow normal users to test a database. Normally, if you're upgrading a production database, you have already validated that the upgrade works correctly by upgrading and testing the dev, test, and potentially staging databases. So when it comes to upgrading prod, you do the upgrade, verify that the upgrade scripts didn't throw any errors, and open up the database for users to do some quick validation. If there is some fear that users logging in would "mess up the database", that implies that you don't have enough confidence in the upgrade to even think about upgrading prod.
Occasionally, you'll have a standby database that gets upgraded and opened up and a select number of users given information on how to connect to the new database. Those users would verify the new database and then some sort of switchover would take place to move everyone from the old system to the new one. That generally requires a lot more work, though, because you have to replicate data during the parallel production phase.

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.

To post code, statspack/AWR report, execution plans or trace files, start and end the section with the tag {noformat}{noformat} (lowercase, curly brackets, no spaces) so that the text appears in fixed format.

Can I have automatic e-mail setting for ADDM and AWR reports??
Can I have Automatic e-mail settings for all my AWR and ADDM reports so I don;t have to run the reports all the time but they can be sent over to my mailbox and I can review them, if at all I can do that then can I bound them to a particular time frame where I can recieve only those reports durin the peak usage of my database.
thanksHi Rohan,
Can I have Automatic e-mail settings for all my AWR and ADDM reports so I don;t have to run the reports all the time but they can be sent over to my mailbox and I can review them,You bet! I do it for all of my databases:
1 - Use a cron (or preferably dbms_scheduler) to schedule the awrrpt.sql execution, directing the report to a fixed file location (e.g. /tmp).
2 - As step 2 from the scheduled task, direct the report as input to sendmail:
For Windows:

Urgent!!! Oracle 11.5.8 AP and GL Report Packages
Does anyone know where I can find Report Packages that provide sample reports for GL, AP and Fixed Assets? Please email me and let me know.
[email protected]
Thanks.Dear Sam!
I know you are Guru. I want to learn Oracle Financial like GL , AP, AR setup or configuration. As you know I was able to install EBS11i on my PC and I also logged in as sysadmin but If you can little bit tell me that after login how I can go to GL , Please be specific that what responsibility I have to select right from beginning after login as sysadmin. If you please tell me some path like select this go next select this . I know it is little anoying but your help in this regard will be appreciated. Just guide us that this is the path to setup GL/AP/AR and from that I can find some way. -
Oracle 9.2.0.5 and Crystal Reports 10
I'm using a Windows XP machine as my client operating system.
When trying to create a report with more than one table in Crystal. The section where I would "link" the tables together, "hangs"... I have to kill the whole application in order to get out of it...
Oracle 8 databases seem to work fine.
Has anybody else ran into this problem? Any more info would be greatly appreciated...
Thanks,
MarciaHi Marcia,
I don't know why the SQL painter would hang in Crystal 10. I have found it too awkward and limiting to use. I use stored procedures for the source data for each report. This gives you the power of PL/SQL and the potential for lots of code reuse to extract your result set for the report. For example:
create or replace procedure p_myreportdata
(< your input parameters if any would be here >
,rs_rpt_data out sys_refcursor)
as
begin
open rs_rpt_data for
select <column list>
from <tables>
where < your filter using input parameters here >;
end p_myreportdata;
Use the Databaes > Verify Database function in Crystal anytime the procedure changes to pick up or remove fields or parameters.
Hope that helps! -
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.

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. -
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. -
How to use awr and addm reports
Hi,
to use awr and addm reports does we should have separate license or oracle server software license is enough.
which tool do we use to read this awr and addm reports in real time.
please give your valuable suggestions.
thank you!Seeing as you seem to want to continue the discussion on someone else's old thread rather than your own one
AWR files in oracle
If i don't then it is difficult to find the queries thata re related to my application as most of those are the sysqueries, i just need schema specific queries in the SQL ordered by Elapsed Time section. Perhaps you are using the wrong tool?
A system-level report like AWR or ADDM is no use to you as it seems your application code is not significant at the system level.
You might want to consider tracing the sessions from your application using client_id or module to identify sessions belonging to your application then possibly use TRCSESS and TKPROF. -
How Far Back Oracle Keep AWR Reports
Hello,
A quick question:
Does anyone know how far back Oracle retain AWR reports in the database? Is this something that we can customize? If it is, can someone offer some insights?
Thanks!The default settings for 'interval' and 'retention' are (60 min and 7 days respectively),
Sample modification using,
execute dbms_workload_repository.modify_snapshot_settings(interval => 120,retention => 20160);
the parameter value is in minutes.
