New DBA help on indexing

I have taken over as a DBA of an Oracle ERP system, and have limited knowledge of ERP environment. A developer on another database has written a query to extract data from the mtl_material_transaction table via a database link. This query is running really slowly as it is performing a full table scan of 300,000 rows. In a normal database environment I would look at putting an index on the table, but can I add indexes to application tables in the inv schema.

Oracle will say so many things, that is only a guidance. Can a business be run without response performance? After all, the first level support person can only say what is in the external and internal metalink. If you do not mind, can post the query and the apps version? You need to index the columns wherever the join occurs. You can run explain plan to find the bottleneck or use tkprof (consult oracle guides).

  • Urgent help with Index page needed

    Can anyone help? I use Dreamweaver 8 to modify and update my
    work's website and I've come across a very strange problem that I
    haven't seen before. I amended a news page, entitled 'news.html'
    and uploaded it as normal last week. I also put a few new pictures
    on the index page and did the same. It was fine at that point,
    however having looked at the page four days later, the news page
    now shows as the home page when you visit the site. It isn't
    calling itself the index page as the browser still shows as the
    page as 'news.html'.
    But the strange thing is, when you first go to the site or
    click the homepage from an internal page, you get a very quick
    glimpse of the original index page before the news page replaces
    it. Almost overwrites it.
    VERY confused. Have tried re uploading the index page and am
    running out of solutions. Any help most welcome.

  • Tabs only open in a new window. Ctl T opens a new window NOT a new tab help-last update this problem started. How do I set FF back to open tabs in 1 window

    Tabs only open in a new window. Ctl T opens a new window NOT a new tab help-last update this problem started 2 days ago. How do I set FF back to open tabs in 1 window?
    There is no plus sign and going into optins and changing settings has not worked. I have uninstall FF and reinstall-keeping my personalization-and that was no help.
    Right clicking on FF Icon to open a new tab, or going up to FF drop down tab and clicking on new tab both do not work.
    Help everything opens a new window not a new tab. there seems to be no way to reset this or to chose a different optin. I just downloaded new tabs at end addon and it didn't do a thing.

    as a first troubleshooting step - does it work like normally when you open & run firefox in [[Safe Mode|safemode]] by pressing the shift key while you open firefox (all other instances have to be closed before)...

  • How can we suggest a new DBA OCE certification for very large databases?

    How can we suggest a new DBA OCE certification for very large databases?
    What web site, or what phone number can we call to suggest creating a VLDB OCE certification.
    The largest databases that I have ever worked with barely over 1 Trillion Bytes.
    Some people told me that the results of being a DBA totally change when you have a VERY LARGE DATABASE.
    I could guess that maybe some of the following topics of how to configure might be on it,
    * Partitioning
    * parallel
    * bigger block size - DSS vs OLTP
    * etc
    Where could I send in a recommendation?
    Thanks Roger

  • [svn:fx-trunk] 8303: This change tries to support legacy usages of StyleManager. setStyleDeclaration() while keeping the new "subject based" internal index of style declarations in sync with selectors.

    Revision: 8303
    Author:   [email protected]
    Date:     2009-06-26 07:50:46 -0700 (Fri, 26 Jun 2009)
    Log Message:
    This change tries to support legacy usages of StyleManager.setStyleDeclaration() while keeping the new "subject based" internal index of style declarations in sync with selectors. We no longer support the invalid usage of constructing a CSSStyleDeclaration with one selector but re-registering it with StyleManager.setStyleDeclaration with another selector.
    QE: Yes, look out for test cases that incorrectly create a CSSStyleDeclaration with a selector AND also use StyleManager.setStyleDeclaration(). I saw one invalid usage in the mustella test file: tests/Managers/StyleManager/AdvancedCSS/mixedSelectors/AdvancedCSS_MixedSelectors, specifically the "CSSStyleDeclaration_CSSSelectorKind_Type_method" test case.
    Doc: Yes, please remove any examples that showed a CSSStyleDeclaration being constructed with a "name" as that is incorrect. You only construct these instances with a selector, or nothing.

  • Definition of new search help in report RFBILA00

    Hello,
    I have created a new search help which I would like to include in the selection screen of the report RFBILA00.
    Does anyone know how to include a new search help in this report which can be used in the screen "Dynamic selections"?
    Best regards
    Peter

    Try by extending collective search helps - like SAKO for SKA1-SAKNR - by appending your custom search help.
    Then I think when you select GL Account description in chart or accounts it will call your custom search help inside it.

  • I bought a new MacBookPro moved everything from old MacBookPro, new machine runs 10.6.7 - but iPhoto won't 'upgrade' the library - just hangs up supposedly while writing new library. help. thanks.

    i bought a new MacBookPro moved everything from old MacBookPro, new machine runs 10.6.7 - but iPhoto won't 'upgrade' the library - just hangs up supposedly while writing new library. help. thanks.

    How did you "move everything" over?
    Migration assistance does not handle the iPhoto library well sometimes - the best way is to drag the bad iphoto library from the pictures folder on the new system to the desktop, connect the two systems together (network, firewire target mode, etc) and drag the iPhoto library intact as a single entity from the old system to the pictures folder of the new system and launch iPhoto on the new system - it will open and convert the iPhoto library as necessary and you will be fine - once you test the iPhoto library you can delete the one on the desktop

  • Oracle DBA Help

    We have an Oracle 9i Database Standard Edition that is in production for about 3 years running on Windows 2003 Server Standard Edition. Our company does not have Oracle DBA. When we purchased Oracle license we didn’t sign up for Oracle Support.
    If something goes wrong with Oracle Database, if we could not figure out the solution on our own, is there any company that provides Oracle DBA help on a contract basis?
    What happens if we get internal errors in the database? Can we still contact Oracle Support?
    Please advice.

    #1. When you purchased Oracle Licenses, I guess Oracle would have provided (Support Identifier or CSI numbers), with that you should be able to create accounts/access with METALINK, which is one form of support Oracle provides. 99.99% of the day-to-day problems are resolved via metalink, oracle forms (like this) and other discussion threads.
    #2. But if you want Oracle personnel onsite, then it needs a different contract or support level, which is very expensive in my opinion. There used to be different support levels like platinum, gold, silver etc., I'm not sure of the classification now, better contact Oracle for additional info.
    I would highly recommend for #1, check the cost involved in #2 compare that with that of hiring a part-time/remote DBA, and see which one works better. If your database is not mission critical, configuring proper back and restore would help bring your database up, but with some downtime.
    Hope it helps,

  • When I try to publish a video in CS5 it adds the extension .new. Help please!

    When I try to publish a video in CS5 it adds the extension .new. Help please!

    Your video is encoded in a format that PS doesn't understand. It's as easy as that. AVIs are just containers that can contain a multitude of different CoDecs and settings. You will have to do some reading up on that matter and then use external programs like VirtualDub, MPEGStreamclip and otehrs to convert your file to something PS understands - if that realyl is what you need. Otehrwise simply move on to "real" video editing apps that can handle all that much better.

      Apple TV will not give me a "password sign in" for iTunes even though it recognizes that my password is wrong (it's new). Help!

    Hi letjimdoit,
    If you are unable to get to the screen that allows you to enter your password on your Apple TV, you may want to first try restarting the Apple TV. Use the steps in this aricle -
    Apple TV: How to restart your Apple TV
    If the same issue continues after restart, you may want to restore the Apple TV. See this article -
    Apple TV (2nd and 3rd generation): Restoring your Apple TV
    Thanks for using Apple Support Communities.
    Best,

  • New Search help - Cloning DEBIX

    Hi I need to create a new search help which will be a clone of standard search help DEBIX. I have to add two new feilds to the DEBIX which will be STR_SUPPL3(street 4) and LOCATION (street 5). When I copied this particualr search help and added the two fields in it , it dosent seem to allow me to get a new selection screen for it and it gives the same selection screen as DEBIX without addition of these two fields where I can input some value. I did add those two fields to my list of fields that I want on my selection yet it gives me a selection screen similar to debix. Then I tried using a database view instaed of teh search help exit used in it , this works but this made the search help case-sensitive which I dont want .
    Can you please advice or suggest what I need to do so that I get a screen with fields that I want and its case-insensitiuve.
    Help will be greatly appreciated.
    Thanks
    Aarav

    Thats right Greg < i have done exactly that way . I created a Z search help with same fields as DEBIX , added my two extra fields , removed the search help exit , created a new Z view table included those two fields there and then added this new search help in DEBI and assigned the parameters , its working fine , but as I said its case-sensitive , I want to make it case-insensitive , so that it goes by the word and not by its cases.
    Please suggest as what needs to be done to accomplish this .
    Thanks
