Plase check your log file.
it is mentioned as below
Enter value for file_name: awr_exp.txt
Loading from the file name: awr_exp.txt.dmp
it should be awr_exp.dmp and not awr_exp.txt.dmp
Also, try to use with default values for: schemaname, tablespace, temp tablespace etc.

Oracle 11G - Oracle AWR export import Query Statistics.
I have Oracle 11G, i have seen the sql statements through Historical AWR option from Top Activites in performance tab. Can i export all AWR query statistics from production machine so that i can analyze all logs after importing it.
How can i know all statistical sql ( information ) and performace of production machine ?
any help ?Hello,
have you checked the DBA_HIST* objects to see what / how was imported?
If the awr export dosn't get the contents of the rolling buffer, then you won't see any session statistics that are only there. If you want to get the contents of the rolling buffer you have to dump the contents of it with :
oradebug setmypid
oradebug dump ashdump 10
and load it into your "test" database.
But before doing this I suggest you read the related metalink documentation if any!!!

Import AWR Html report into another database
Hello,
Im in 11gR2, is it possible to import the AWR Html report from database 1 into another database 2?
I would like to use ADDM from another database 2 to analyze the AWR Html report of database 1.
Thanks,AWR report importing on another database
i dont think so -
I am testing a Sony a7r, shooting RAW. I can't seem to import the files (which are .awr) into my Lightroom 4. Anybody know what options I have? Thanks!
Support was added by Adobe for this camera model in LR 5.3 and ACR 8.3. see the link below.
Camera Raw plug-in | Supported cameras
You can download the latest trial version of LR 5 the current version is 5.7.1 and use tor 30 days.
The other option is to download the latest Adobe DNG Converter (version 8.7.1) for free and convert the Sony .arw files to dng format and they will work fine with LR 4.
Make sure you retain the original copies of the .arw files. -
Enq: TX - row lock contention in AWR reports
Dears,
One of my friends asked me to give him a help on analyzing a performance problem they are experimenting from time to time. First of all I am sorry to tell you that he didn’t gave me a lot of information. I will share with you all what I have been sent and would like to have your precious advice according to the available information.
It is a third party software installed on oracle data base 10.2.0.4.0. He said that from time to time the application hangs. He sends me an AWR reports supplied by the local DBA. Unfortunately, the local DBA send only the AWR information he thinks are most important to be looked at (he did not include the load profile and the instance efficiency Percentages part in this AWR for example).
Here below is the available information I can share with you

I am waiting to have the table table1 script and its indexes
Given those information I think that the locking problem is due to this update on table table1 which is not followed immediately by a commit or a rollback. But, instead, several selects that might be taking a long time are done before reaching the commit that ends the lock on the table table1
What do you think about the possible reason of this lock?

Awr and dba_feature_usage_statistics
Hi Gurus.
I found below important information about the license.
http://download-east.oracle.com/docs/cd/B19306_01/license.102/b14199/options.htm#CIHJJBGA
It says that to use AWR features(to access v$active_session_history, dba_hist_xxxxxxx, oracle_home/rdbms/admin/awr*.sql, etc...), we need to extra license, correct?
after I installed enterprise edition and set up EM( not grid ) for test, I have questions
1. I checked 'remove access' on the management pack access screen of EM's setup menu.
but still I can find all views(dba_hist_xxx, v$active_session_history, etc..) about AWR.
is it correct?
2. I ran a $ORACLE_HOME/rdbms/admin/awrrpt.sql script, but still I can find that the value of column 'Currently_Used' of the name 'Automatic Workload Repository' from the view 'dba_feature_usage_statistics' is still 'FALSE'.
is it correct?
thanks.

is it correct?Yes. It only stops the display in EM. Since some of these views are also used for other things internally, it does not remove them. It's up to you to NOT access the views.

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

DBID_NUM NUMBER;
INST_NUMBER NUMBER;

/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;

select dbid into l_dbid from v$database;

select max(snap_id) into l_last_snap_id from dba_hist_snapshot;

dbms_output.put_line(rec.output);
end loop;

Hello,
Can anybody guide me how to generate an AWR (automatic workload repository) report at schema level? Actually I have created one user name xyz and imported some 1000 objects (tables, views etc) .
I have little doubt here , when we create one user ,is schema for that user will it create automatically …..if its true then I need to generate one AWR report for that user or schemaI don't think this is possible: AWR only works at database/instance level and not at schema level.

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.

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 to open AWR in PSE 12 running on XP
I am running Windows XP and understand I must use DNG converter to open AWR files in PSE 12. I have downloaded DNG converter, but still do not know how to open the AWR files. I appreciate any help. Thanks.
The dng converter converts the files to dng copies which can then be opened in pse 12.
For example, in the dng converter dialog, for the source folder you point to the folder with your sony rx100 images and then for destination, choose that folder or a different folder.
Then the dng converter converts your images to dng copies, which can be imported into the pse 12 organizer or opened in the pse 12 editor.
Another thing you could do is install the 8.3 dng converter (to install the needed profiles) and then copy the camera 8.3 plugin to
http://www.adobe.com/support/downloads/detail.jsp?ftpID=5694
(dng converter 8.3 windows)
C:\Program Files\Common Files\Adobe\Plug-Ins\Elements 12\File Formats
to replace the existing camera raw.8bi already in that folder, then you could just open the native sony rx100 files without the need for the dng converter.
https://workspaces.acrobat.com/?d=uP7Dof8zfUMEhBu-IQsmxQ
After you download the 8_3 Camera Raw.zip, extract the folder and copy the camera raw.8bi file to
C:\Program Files\Common Files\Adobe\Plug-Ins\Elements 12\File Formats
Then hopefully you should be able to open your sony files without having to use the dng converter. -

AWR-Avg wait(ms) and the right storage platfom
Dears,
I have just one question to clear relatively to a conclusion I can make or not when reading AWR. Let's take the following Top 5 Timed Events
Top 5 Timed Events Avg %Total
~~~~~~~~~~~~~~~~~~ wait Call
Event Waits Time (s) (ms) Time Wait Class
CPU time 356 94.5
CSS initialization 8 13 1647 3.5 Other
db file sequential READ 2,428 3 1 0.8 User I/O
control file sequential READ 4,547 3 1 0.7 System I/O
log file parallel WRITE 333 2 6 0.5 System I/O
----------------------------------------------------------------------------------When looking to the 1 ms of Avg wait to read a single leaf block (from disk when not in cache), can I conclude that the machine has a very acceptable storage service that services a physical I/O very quickly?
And when looking to the following second example (where I have deliberately exagerated the Avg Wait(ms) times)
Top 5 Timed Foreground Events
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Avg
wait % DB
Event Waits Time(s) (ms) time Wait Class
db file sequential read 465,020 3,969 29 47.4 User I/O
DB CPU 995 11.9
db file parallel read 2,251 322 143 3.8 User I/O
db file scattered read 15,268 153 30 1.8 User I/O
gc current block 2-way 108,739 116 1 Could I also "jump" to a conclusion that those average wait time for single I/O(29 ms) or multi block reads(30 ms) are serviced by a slow storage service?
Thanks for your help
Mohamed HouriHi Randolf,
I agree that if an AWR looks like this, it doesn't necessarily mean that the database doesn't have any performance problems. Yes, there can still be inefficient plans. But those inefficient plans in this case aren't a global problem. I.e. if the system still has free CPUs available, then tuning them won't have a global effect. Imagine that you have a database with CPU time responsible for 95% of DB time, but only 10% of the host CPU. Imagine that you find a SQL statement that is responsible for a large portion of the CPU usage within the database. There is a good chance that this statement has an inefficient plan which can be improved by tuning -- but in this case it would only make sense if that statement is important on its own. If that is not the case (e.g. the statement is a part of a batch job and no one care whether it completes within 5 minutes or 10 hours) then tuning it would be essentially a waste of time -- in the very best case you would reduce DB CPU usage from 10% to 5% or 1%, which no one will ever notice.
This is very different from cases when DB time is dominated by I/O- or concurrency-related waits (when top-down approach works fine).
So that's one of the reasons that I'm saying that high CPU time is not a problem. Another reason is that people often tend to perceive high CPU time % in the AWR report as an indication that the system is running out of CPU, which is generally wrong.

Hi ,
we having two environment SIT1 and SIT2 on which some Sieble CRM application runs
Database : 10.2.0.3 OS: AIX 5L Sereis
Every weekend there are some repository import Job happening on application level which import product data into database
On SIT1 it takes 1 hour , where as on SIT2 same job take approximetly 3.5 hours
the server configuration and Database configuration are same on both the environment.
We are unable to understand why it consume so much time on SIT2 environment since the amount of data import on both server is equal.
During application import Job , no other task run on database server.
Any suggestion to tune this , would highly appricited.
Thanks to you allthanks for kind support anantha , these are not imp/exp or impdp/expd jobs.
there are some jobs or task run at application level which insert/import product data into database.
Unfortunetly the AWR retention had been too short and snapshot details been purged out now.
yes, we will monitor session_wait and locks , latches if any during this repository import job this weekend.
As this issue been assigned to me today only , couldn't doo much at the moment :-( -
DB version:10gR2
After looking at Top 5 wait events and SQL statistics, what is the next most important thing i should be looking for in an AWR report?This would depend on the top events that you have seen. For example, if you have seen that in the top 5 wait events, there was very high DB File Scattered Read , it means that there are statements which are predominantly going for full table access. So you should look upon for those queries. Or if there is a high Latch Contetion, for example, Shared Pool Latch Conteions ,it means that there are lots of sttement which are going for hard parse and are contending for this latch. So you should look for those sql which are having more cnstants and are not using bind varaibles.
So its not a standard way but it is depending on what you see. Over Jonathan Lewis's blog, there is an excellent series of how to read Statspack report. I shall suggest to read it. This would make a good base to go through with AWR report also.

Unable to import .jpg versions
I recently purchased Lightroom 5 and have updated to 5.2. I did my first import from a file folder to the catologue. I noticed that all my .awr files imported and any edited .jpg imported, but the original .jpg would not import if there was a corresponding .awr file. I'm not sure how to fix this. I would like all my photos imported. Any ideas?
From the menu bar go to Edit >Preferences >General tab> Import options > Select "Treat JPEG files next to raw files as separate files".
The next time you import files lightroom will import both. For the existing files when in the Library module use Library > "Syncronize Folder".
Maybe you are looking for
