Performance and Tuning

I'm somewhat new to oracle. I have an oracle install that is Standard Edition 11g on windows 2003. They did not and won't purchase the performance tuning pack or support for the database. What is available to me to look at the performance statistics for the database? What tools can i use to gather baseline stats? I appreciate any help.
Thanks.

Shafiulla SyedJust for clarification. The original poster stated that he is running the Standard Edition of Oracle 11g. AWR cannot (legally) be used with the Standard Edition of Oracle. Using AWR (legally) requires the Enterprise Edition of Oracle and the purchase of the additional cost Database Diagnostics Pack and possibly the Tuning Pack.
The responses provided by Centinul and Mark are very helpful.
One approach is to monitor the Time Model data, CPU usage, and Wait Events - there is an example at the following link that will do that for you using a web interface (be sure to take a look at the follow-up post that provides the source code):

How similar is the performance and tuning 1z1-064 (12c) to the 1z0-054 (11g)?

I had taken the Oracle 11g performance and Tuning class from Oracle.
I am just wondering how close the 1z1-064 will be to the 1z0-054.
I am also studying for the 1z1-064 exam.
Are there any books out yet, or just the otn material.
Thanks Roger

Hopefully John Watson will pipe in on this. I know he has taken both exams. He recently noted on the OraFAQ forum that he had taken both the 1Z0-063 and 1Z0-064 beta exams. His comments about them there were:
"I would say that looking at the exams as a whole, there is a huge improvement over the 10g and 11g equivalents. The new exams cover a lot more material in a lot greater detail, and are a lot harder. These 12c exams are a Good Thing for the profession. They should filter out a lot of exam-cram only DBAs"
It's not clear to me how much of that comment was directed at 063 and how much at 064. The topic list for 063 is much larger than that for 053. However, the topic list for 064 is actually a bit smaller than that of 054.

Trying to get hold of my own course pdf for performance and tuning 11g, would oracle have list of classes i have taken?

Tyring to find my own course pdf for oracle performance and tuning 11g that I took thru Oracle.
I am studying for 1z0-064 currently using 10g perf tuning book.
Would Oracle have list of Oracle classes that i have taken.
If they do, is there any way to get hold of the pdf from the class that I took?
I realize that this is a stretch.
Roger

Roger,
This is a question that you'd need to contact Oracle University Support about - Oracle University Contact Information. They should be able to help you.

Can anybody recommend useful performance and tuning books. I plan to take the 12c perf tune beta on March 21st

Can anybody recommend any useful performance and tuning books.
I should probably limit my search to 11g or higher.
I am starting to prep for the 12c perf and tuning beta I have scheduled on March 21st.
Thanks Roger

Hi,
I will review your review.
I do see this Oracle 12c book at Amazon written over a year ago.
Its not a certificaiton book.
I also did take the course at Oracle for 11g performance and tuning.
Amazon book:
Oracle Database 12c Performance Tuning Recipes: A Problem solving approach.
Thanks Roger

Studying for Oracle 11g Performance and Tuning exam - 1Z0-054

Hello all,
I want to attend to this exam and I'm looking for interesting and usefull studying path. Sure manuals on tahiti are needed.
Neither sefltestsoftware not Testking has released a proficiency test for this exam. I was only able to find a test from Braindumps here (http://www.exam4test.net/1Z1-054) but not sure this is a serious material.
Any hints about this material and / or any other suggestions?
Thanks
Stefano

Hi Stefano
Seems that our friends from Certguard aren't sure that this a legal provider, but the look and feel would say to avoid that site.
Try the http://www.certguard.com/braindump-quiz.asp it matches very well to the site or?
Besides that while looking on the domain i found that
Domains being linked from exam4test.com
* Traffic rank 252963. test-inside.com
* Traffic rank 940584. exam4test.net
and those sites aren't clean.

[1Z0-054] Oracle 11g Performance and Tuning

Hi all,
does anyone has already taken this exam? I just want to know which study materials you've used and also if there's any online testing software.
I've downloaded ucertify test for this exam but I'm not sure that is a great and affordable testing tools...
Thanks
Steve

Some people have given more positive opinion on some more recent Ucertify practice tests than this on this forum.
I would not completely write off Ucertify practice tests .... but if you buy them:
They may not have same quality as SelfTestSoftware
They may not represent value for money.
They probably give full topic coverage.
They could even have incorrect answers for all I know.
However they may help you identify some weak areas.
If you buy expecting a 5*Hotel you may be disappointed, if you buy expecting a room with a hammock and cockroaches you may be happy about it.
(Please note I have not bought the tests .... it is only from feedback to this forum).

Unresolved Questions in Performance and Tuning

In an attempt to close some threads neglected by the OP's this year and achieve SDN's goals with regards to points (see the Welcome thread about the UN food program and other donations made by SAP based on annual contributions) I and other moderators will be combing through selected threads from the current year and assigning points as moderator.
It will be impossible to do a perfect and complete job of this, but we will do our best to be fair and concentrate on those who have contributed valuable inputs of information (and are just a few points shy of the 250 mark) but not been recognized appropriately.
Also please close your own threads and do not dump them all to the top again unless there is a good reason to comment further (the comment field is not mandatory!)

Can i use "Oracle Database 12c: Performance Management and Tuning " training for getting certification on "Oracle Database 11g: Performance Tuning 1Z0-054"

i have taken "Oracle Database 12c: Performance Management and Tuning new" training from oracle university. Now i would like to get certified on "Oracle Database 11g: Performance Tuning 1Z0-054" exam. Is it possible ?

I essentially endorse and refer you to Matthews' and John's post above.
I would differ with slightly with Matthew because my guess is you would often be able to use like for like 12c training for an 11g certification ( I believe there are precedents). BEFORE ANYONE ASKS THE OTHER WAY DOESN'T HAPPEN.
.... but totally concur with Matthew you would ill advised to procede on that basis without one of:
- This being advertised as possible on the website : e.g. https://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=654&get_params=p_id:169 ... option 2 show courses.
- Confirmation from Brandye
- Confirmation from an Oracle Certification Support Web Ticket ( http://education.oracle.com/pls/eval-eddap-dcd/OU_SUPPORT_OCP.home?p_source=OCP )
... The more common (and in my opinion usually better) way would be get your 11g DBA OCP ( or higher first) and then take the 1z0-054. I am almost certain they will accept your 12c course for the 11g DBA OCP.
If you are choosing the route of not being a 11g (or 12c ) DBA OCP first but are on option 2 and relying on the course for certification then the issue is more in the balance and you are even more strongly advised to get confirmation before proceding (remember if the rules need to be changed for you only then any profit out of the exam is lost).
In general my understanding is Oracle would prefer to encourage people to train on the latest version of product that is available for training and will prefer to avoid restrictions which would cause you to train at a lower version. ( This is simply my guess at Oracle University Policy ... personal opinion only).
Having said all I have said I'd encourage you to go with the advice of the earlier two posts.

Oracle 11g SE One Performance Monitoring and Tuning

I've recently "downgraded" a couple databases from Enterprise Edition to Standard Edition One and in doing so lost the use of Grid Control, specifically Performance Pack. Now, of course, monitoring and tuning, is a bit more cumbersome.
Can anyone offer advice on methods specific to Standard Edition One for monitoring/tuning databases? Specific SQL statements you use, 3rd party software, built-in packages in the database that can be used?

There are a large number of performance views that can be queried, and if you capture the current values, wait a known amount of time (whether 1 minute or an hour) and then recapture the current values, you can determine by how much the statistics have changed over the time period. Do not query the views that begin with either "DBA_HIST_" or "DBA_ADVISOR_", since those views belong to the extra cost licenses that are only available with the Enterprise Edition (access to the views is audited).
You could, for instance, track the changes in the time model statistics, and use that as a basis to determine if anything else should be examined. It would probably also make sense to track the changes in the various non-idle wait events. If you have a Windows client PC, you can experiment with one of the scripts that I wrote which tracks changes to the time model statistics, changes to the OS statistics, and changes to the wait events:
http://hoopercharles.wordpress.com/2010/02/09/working-with-oracle%e2%80%99s-time-model-data-3/
If you do not have a Windows client PC, you might be able to determine how the script works and build your own solution.
