Is custom views effect the performance of EBS?

We are using EBS r12.0.6,, database 0g R2.
Our developers are writting some views to sumarize the data and those views are using in custom reports.
Is this effect the EBS performance?

Technically, just doing select 1 from dual will affect the performance. The impact may be a pico second but it will certainly be there.
My point is that it is very difficult to answer this question without knowing the kind of views and the queries that are run on the views. It is best to analyze the report request to identify performance impact (if any).
views to sumarize the data Keep in mind, for some summary type of reports, it might be better to write materialized views instead of regular views OR do the summarization on a data w/h
instance or a reporting instance if you have one.

  • [iPhone] Place a custom view below the status bar and above the navbar

    Hello,
    How can I add a custom view between the status bar and the UINavigationBar?
    The Myspace App does this so I know it can be done. It has a custom bar between the status bar and the navigation bar which displays the myspace logo and a logout link. I would like to do something similar w/ my app.
    Thank you

    You can move the tabs to the lower position just above the browsing area without using an extension with code in userChrome.css as basically you only need to give the Tab bar a higher -moz-box-ordinal-group value (most toolbars have a default -moz-box-ordinal-group:1 to show them in DOM order).
    *[[/questions/997353]] How can I put the Tabs back below the navigation bar?
    You can look at the Classic Theme Restorer extension to restore some functionality that was lost with the arrival of the Australis style in Firefox 29.
    *Classic Theme Restorer: https://addons.mozilla.org/firefox/addon/classicthemerestorer/
    *You can check out the settings of the CTR extension via its Options/Preferences button on the "Firefox/Tools > Add-ons > Extensions" page.
    *You can find extra toolbar buttons and more toolbar settings in Customize (3-bar Firefox menu button > Customize)

  • Does the ETL workload effect the performance of reports?

    Hello
    There are several heavy ETL processes running on production. Do they effect the performance of the reports that user may execute during this time?
    thanks

    Definitely... Your server has a finite number of resources available to share with all those processes... Running a report is just one more process... Users can be (and are) impacted by other processes in the system...

  • About how many CDs can I put on my hard drive before it effects the performance of me iMac/

    About how many CDs can I put on my hard drive before they effect the performance of my imac?

    Well, it depends on how much content is on the CD. You should have, at a minimum 10 - 15 GB of empty hard drive space at all times - more is much better. I do a fair amount of video/graphics editing and in order to render and burn properly, I need at least as much empty hard drive space as I have files in my current project, which usually means at least 150 GB or more. So, to be safe, my goal is to have a minimum of 250 GB empty space at all times - the OS will thank you if it has more room to work with.
    So, add up what you want to put there and keep watching your hard drive space diiminish - it's best to have space hogging files on an external hard drive to keep your internal working well.

  • Does Row Wise Initialised block effects the performance of OBIEE 10.1.3.2.0

    Hi,
    I am trying to implement the security in my application using row wise initialisation block. Could any one help me with below mentioned doubts:
    1) Does it effect the performance of the OBIEE server.
    2) Cons with row wise initialisation block used for implementing security which uses Oracle customise function in it. this initialisation block is been created for implementing 2 level security.
    Thanks
    Savita

    Savita,
    Answers to your questions are as follows:
    *1) Does it effect the performance of the OBIEE server.*
    No. This is part of the Oracle BI Repository modeling process for Oracle BI 10g.
    *2) Cons with row wise initialisation block used for implementing security which uses Oracle customise function in it. this initialisation block is been created for implementing 2 level security.*
    There really aren't any cons. To get the security you are seeking row-wise security in Oracle BI 10g is the route you must take. In addition, this process is used widely in Oracle BI 10g for numbers of consecutive users and total users/groups in an LDAP or security group table ranging from hundreds to tens of thousands with nothing but success. So, don't worry about implementing this as your implementation will be sound by configuring row-wise security.

    Thanks EBSDBA and Helios for your time.
    Are there any scripts/reporting tool that helps me monitor iAS performance other than OEM for EBS?
    Note:370583.1 is very helpful in monitoring JDBC connections. Are there any similar Notes/scripts that can answer my questions:

  • Adding Flex-field to Custom View in the Worklist

    Hi,
    I am using OAS10133. I have mapped a SIMPLE_TYPE payload attribute to a flex field label in the worklist. I created a custom view. I want to display this playload attribute as a column in custom view and want to make it searcheable. But when I create the custom view, then at the time of selecting the columns, I do not find the name of this label listed in the dropdown.
    I have also made an entry in WorkFlowLabels.properties file.
    Can anyone please let me know if I need to follow any other step to display the flex field label as a column in custom view?
    Thanks in advance.

    Hi Pete,
    There are two exits that were used.
    A user exit IMRC0001 (MeasPoint/MeasDoc: Exit before update (after COMMIT WORK) /  FM: EXIT_SAPLIMR0_001) for the transaction IK11 to enter the value for the custom field. When the measuring document is saved a pop up appears wherein the value for the custom field can be entered.
    A menu exit IMRC0003 (MeasDoc: Menu exit for customer-specific function / FM: EXIT_SAPLIMR0_003) for the transaction IK12 in order to change the custom field.

  • Does triggers effect the performance

    Hi all,
    I have 3 triggers on the table....2 of which are select triggers and one is it insert into other tables whenver there insert/update/delete for each row..
    so if i do dataload say 1 lac rows on the table which has trigger.
    does trigger slows down the performance.
    thanks

    does trigger slows down the performance.As compared to what?
    If the trigger is properly written, and if the action that the trigger is to perform would have been performed anyway by the application but at the application level, then perhaps a trigger could be faster.
    If the trigger is doing stuff that should have been done elsewhere (eg: instead of declarative constraints) then a trigger could be slower.
    If the trigger is doing stuff on a per-row basis that could be done better on a per-set basis, especially when handling bulk data (which is the specialty of an RDBMS, much to many developer's surprise), then realize we often turn off constraints for exactly that reason during bulk loads.
    If the trigger is doing stuff that it shouldn't be doing at all, well ... I let you figure that one out.
    In the mean time, I have no idea of the context of the question and therefore the answer - like so often in Oracle - is 'it depends'.

  • Best pratices for the customizing about the performance

    Hello,
    I would like to know the list of the best pratices for the customizing BPC NW 7.5 about the performance.
    Best regards
    Bastien

    Hi,
    There are few how to guides on SDN which will give you a basic idea on script logic. Apart from this, you can refer to the help guide on help. sap.com.
    The templates might also effect the performance. The number of EVDRE functions, the number of expansion dimensions, the number of members on which expansion takes place will effect the performance. A complex formatting in the template will also effect.
    Hope this helps.
