Oracle Memory Issue/ performance tuning

I have Oracle 9i running on Window 2003 server. 2 GB memory is allocated to Oralce DB( even though server has 14GB memory)
Recently, the oracle process has been slow.. running query
I ran the window task manager. Here is the numbers that I see
Mem usage: 556660k
page Faults: 1075029451
VM size: 1174544 K
I am not sure how to analyze this data. why the page fault is so huge. and Mem usage is half of VM size?
How can I do the performance tuning on this box?

I'm having a similar issue with Oracle 10g R2 64-bit on Windows 2003 x64. Performance on complicated queries is abysmal because [I think] most of the SGA is sitting in a page file, even though there is plenty of physical RAM to be had. Performance on simple queries is probably bad also, but it's not really noticable. Anyway, page faults skyrocket when I hit the "go" button on big queries. Our legacy system runs our test queries in about 5 minutes, but the new system takes at least 30 if not 60. The new system has 24 gigs of RAM, but at this point, I'm only allocating 1 gig to the SGA and 1/2 gig to the PGA. Windows reports oracle.exe has 418,000K in RAM and 1,282,000K in the page file (I rounded a bit). When I had the PGA set to 10 gigs, the page usage jumped to over 8 gigs.
I tried adding ORA_LPENABLE=1 to the registry, but this issue seems to be independent. Interestingly, the amount of RAM taken by oracle.exe goes down a bit (to around 150,000K) when I do this. I also added "everyone" to the security area "lock pages in memory", but again, this is probably unrelated.
I did an OS datafile copy and cloned the database to a 32-bit windows machine (I had to invalidate and recompile all objects to get this to work), and this 32-bit test machine now has the same problem.
Any ideas?

  • 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.

  • Dates for "Oracle Database 11g: Performance Tuning" exam

    Hi!
    Today Oracle posted info about the new Oracle Database 11g Performance Tuning exam needed for the new expert certification:
    http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=41&p_exam_id=1Z0_054#2
    It says that pre-registration for the beta exam starts today, however, it does not say when the beta phase starts and ends. Does anyone know?
    Thanks,
    Marcus

    Hello Hussein
    Yes true, I remember it for the OCE and Linux exams they rescheduled the end date several times. As far as I know it is related to the number of participants and the given feedback.
    I've also participated to several other exams, and I must admit that it is a long and hard process to get through. When I got the feedback 10 weeks after the beta period closure, I had to review nearly all the topics to get the exams passed the second time. But this it is a cheap and good exam preparation.
    What about you Hussein? Do you think that's trivial?

  • Oracle Database 11g: Performance Tuning exam 1Z0-054

    Hi,
    I want to take the certification Oracle Database 11g: Performance Tuning exam 1Z0-054 and want to write the exam.
    To earn the OCE credentials, I know that we need to take training from Oracle University. I am not an OCP currently.
    Can I write the exam now and later take the course to meet the certification requirements? I know it is not the right way, but I can not pay $3000 for the course as of now. I can write the exam through self study. I want to check if I can take the exam now and later take the course.
    Is it mandatory to take the course before taking the exam?
    Thanks,
    naveen.

    naveen.Indeed you can take the exam now, and subsequently earn the 11g PERFTUNE OCE credential when you either:
    1) complete, submit and get verified the OU authorised 11g perftune course (possible but seems a little cart before horse).
    or
    2) Become 11g DBA OCP.

  • 1z0-054: Oracle Database 11g Performance Tuning Expert

    I am planning to give the exam 1z0-054 to get the certification, "Oracle Database 11g Performance Tuning Expert".
    The Certification Path says that, if you are and "OCP DBA 11g" then you can directly take this paper, and there is no Instructor Led Training requirement. Therefore, I decide to prepare for it by my own. Can someone guide me about the study material and dumps?
    Regards,
    Ahmer Mansoor

    Therefore, I decide to prepare for it by my own. Can someone guide me about the study material and dumps?First of all, the word 'dumps' has a specific meaning. It is shorthand for 'brain dumps' which are illegal and can cost you this certification and any others you have taken.
    http://blogs.oracle.com/certification/entry/0477
    Second -- there currently is no study guide or book specific to this certification available at this time. I write study guides and this one is actually next on my list once I complete the current book for *1Z0-117: Oracle Database 11g Release 2: SQL Tuning*. I won't have a guide for 1Z0-054 until some time in May most likely. That said, I have some links to legal study material on the companion website for my guide series relevant to topics for this exam. It also has links to the Oracle documentation that contains information you need. Once I start writing the book for this exam, the links will expand rapidly as I research the topics for it and the documentation links may expand as well.

  • Select stmt issue, performance tuning.

    Hi Group,
    I have a question.
    There is a select stmt which is using inner join, and its taking good amoutn of time to get executed. I was told to tune the performance of that query. And my TL suggested me to use ranges in that select stmt, like the sign, option, low, high.
    Could you please help me out on this issue? Urgent.
    Thank you in advance.
    Regards,
    P. Varun Kumar.

    They are suggesting to use ranges rather than For all entries.
    Here is the query:
    SELECT b~kunnr
             b~zz_echan_reg
             a~title
             a~first_name
             a~last_name
             a~email_addr INTO TABLE gt_ecustomers
                          FROM zyd_contacts AS a
                         INNER JOIN kna1 AS b
                            ON ayd_kunnr = bkunnr
                         WHERE zz_echan_reg EQ 'X' OR zz_echan_reg EQ 'A'
                           AND zzcap_divert EQ space

  • Oracle Performance Tuning Certification

    Hi Guys
    I am going for 10g OCP then maybe 11g Tuning Expert Certification.
    1. I look at the prerequisites of 10g Performance Tuning course:
    Required Prerequisites:
    * Knowledge of Database Administration
    * Oracle Database 10g: Administration Workshop I Release 2
    * Oracle Database 10g: Administration Workshop II
    * Oracle Database 10g: New Features for Administrators Release 2
    Does this mean that it is COMPULSORY that I take the 3 courses above first before I can take the Performance tuning course? This cost a lot of $$$! ; o
    2. Where can I get 11gTuning Expert Certification practice questions? From the 11g Performance Tuning course? Couldn't find it in SelfTestSoftware....
    Advance thanks!

    Hi,
    Exam # 1Z0-044 does not exist.
    Why there is no Oracle exam for Performance Tuning for 10g?
    There is one for 9i and there will be one for 11g (currently it is in beta).
    Lorrys,
    I guess this needs to be corrected a bit. 9i exam is a part of teh OCP track, its not an individual exam which you may clear and would be awarded an certification for it. OCE is itself is an certification track and unlikely OCP, it doesn't need multiple exams to be cleared. You just have to clear one exam and youwould be awarded teh certification. Now, about the 10g exam of PT OCE not being there and given in 11g, it should make sense as 11g is already out and there is no point in launchnig a NEW certification track for a previous version. So that's why 11g PT is launched for the newest release, which is 11g.
    That said, I am not from Oracle so its just my own opinion about your comment.
    HTH
