Thanks !These are all dynamic parameters and thus can be changed without requiring the db to be down. That said, please check the oracle documentation to know about such things. Here is the link to the documentation, http://tahiti.oracle.com .

  • Can you change the value of a variable that is reset by a parameter?

    Sorry if this is simple but I just crashed a package and can't do an autopsy. I suspect I sent it into an infinite loop. I know you can't change the value of any passed in parameters. What I tried to do was have the parameter set the value of a variable
    and then I tried to change the value of the variable. Is that even allowed?
    I was trying to do this:
    MyCheckVariable = MyParameter (which equals true)
    (some cool stuff happens)
    MyCheckVariable = False
    I hit F5 and my package turned into the Energizer Bunny. Is the way I try to reset the variable the culprit?

    This is a prototype so I just created a project parameter and set it to true. In the real world the parameter will be used to control an optional part of the process because on a re-run after error that part doesn't have to be ran again.
    So when I say MyCheckVariable = MyParameter (which equals true) in reality what I actually have is in the variables window I'm using an expression and it looks like this in the variables window
    name = runDownload
    Scope = Package
    Data Type = Boolean
    Value = True (but greyed out)
    Expression = @[$Project::param_runDownload]

  • How can I change the value used in a Criteria Rule in a Subscription agent

    Dear mobile heroes.... How can I change the value used in a Criteria Rule in a Subscription agent in a quality environment? (CRM 70 SP04).
    I have built a subscription agent in dev, which uses a static where clause to filter activity_object on VKORG. I need to filter on a different VKORG value in the quality environment, but when I change the value of the sales org, the change is not saved. I have tried this even non 'activated'  subscription agents, but it still does not appear possible to change and save the changes.
    This poses a big problem because the VKORG value I want to use does not even exist in the dev environment, so I could not even rebuild in dev and transport the new agent to quality. Can anyone help me?

    Too old to care now.

  • Can you change the value of app_user?

    can you change the value of app_user?

    Hi Scott,
    Thanks for being patient.
    A lot of the reports are based on personal information tied to the username. so on my reports I use app_user to pull the information. the app is a production app so when problems arise a lot of the time is user error but the users are in some other state so i need a way to look at the same thing they are looking at. I need to be able to sign in as them but since the app uses sso they cannot give me their corporate passwords. when i changed the value of g_user it changes but only for the scope of the region that i changed it in. it does not persist for the session.
    Thanks Fernando

  • Can i change the value of the discrete states in EMI_CB_CalculateResetStates?

    can i change the value of the discrete states in EMI_CB_CalculateResetStates?
    The help of LabVIEW said that calculates the values to which to reset the states of an external model in it.But it didn`t said how to reset the discrete states in it.EMI_GetNextDiscreteStates said it can be called only within the EMI_CB_CalculateDiscreteStates function.So if the discrete states can be reset in EMI_CB_CalculateResetStates,how to do it?
    THX

    What is EMI_CB_CalculateResetStates?  If I knew what you were asking about I could give a little more inteligent answer.

  • How can I change the value of "colorscheme" parameter at runtime?

    Hello all
    Can I change the value of colorscheme at runtime ?
    This parameter can be config in formsweb.cfg file.
    I want to put this colorscheme as "User Preferences" in my application.
    Please help me if some one knows how to achieve this.
    From
    Chirag Patel (Nairobi)

    Hi,
    Try the following. This might help you.
    Edit you Formsweb.cfg file with following code (add the code to your file):
    [look1]
    separateFrame=True
    lookandfeel=Generic
    [look2]
    separateFrame=True
    lookandfeel=Teal
    [look3]
    separateFrame=True
    lookandfeel=Khaki
    and save your file.
    Now, when you call your form in the address bar look for " ? ". After " ? " add config=look1 now your form will take Genric look & feel.
    or
    config=Teal now your form will take Teal look & feel.
    That's how you can change the look & feel at run time.
    Hope that you understand what i want to say......

  • Can I change the order of lines in a drop-down menu?

    Can I change the order of items on a drop-down menu? Specifically, the "open" menu that comes up when I right-click on a link.
    Putting "open in new tab" on top of "in new window" makes sense, of course, since it is used more often. But I do a lot of surfing, and had the old position in muscle memory. Re-training my brain to click on the first line instead of the second is taking a long time, and makes me grumbly.
    I'd love to put it back to the old order. Can I? and, if so, how do I do it? (Please give me detailed instructions, IOW, please assume I am a complete simpleton, because sometimes I am.)
    HP G62 w/ Win 7 home premium. If it matters, it's 64-bit.
    And my old desktop, which has, yech, Vista. (I haven't upgraded it to F4 yet.)

  • My mum set up an iCloud account and forgot the password, and this caused me to create a new account. The new account works for the App Store and all that, but I can't change the initial iCloud account without the password. Help?

    My mum set up an iCloud account for my iPhone 4 but forgot the password. This caused me to create a new account, and it can be used for the App Store and iTunes and all that, but I can't change the initial iCloud account (the one my mum made). My device keeps prompting me for the password every few minutes after updating to iOS 8, and I've tried every option possible to retrieve the password, but I don't even know the answers to the security questions and I can't find the password reset email anywhere and I don't know the back up emails my mum used. I literally cannot find any legitimate way to sign out of the initial iCloud account without entering a password (which neither I nor my parents know). Is there a way for me to retreive the password or change to my new account without the password?

  • I can't change the values in Property Palette

    I am working with Report Builder 3.0.5.17
    I generated a report layout with the wizard ;altough i set the width of the fields to certain dimensions (30 or 15),in the Property Palete it is diffrent(4000! or other and the most important thing : i can't change it! When i run the report, i get no data, it's empty! (i verified the interogation with Toad and everithing's fine)
    What could be the problem?
    Thanks!

    Hi,
    I'm quoting from Reports Builder Help:
    The Width property specifies the maximum number of characters that the values of the column can occupy. This Width refers to the width that Reports Builder uses internally for the column. It affects such things as the calculation of summaries and formulas. The size used to display the column's data, however, is determined by the size of the associated field in the Paper Layout view and its Vertical Elasticity and Horizontal Elasticity properties.
    If the Column Type is Database Scalar and the Datatype is Character, Date, Number, or Raw, Width is uneditable. However, this does not mean you cannot control the width of the column's values in the report output. You can change the width of the values in the output by modifying the field's width in the Paper Layout or the Field properties.
    About the report not containing any data, there could be several reasons:
    Make sure that the physical width of the columns is enough to display the values. Tyry changing the values for Horizontal / Vertical Elasticity in the property inspector.
    Also check the vertical / horizontal elasticity of the frame / repeating frame surrounding the field.
    Make sure that you are connecting to the DB with the correct username.

  • How can I change the value in a stepper cell

    In Numbers 2.3 I was able to change the value in a stepper cell by highlighting the value and using the arrow keys to increase or decrease the value. This was a very easy way to input data. Numbers 3.0 when I do this is moves to another cell
    Is there a way to get the use of the arrow keys to change the values in 3.0?
    Thanks

    I use number to keep a running daily tally of the productivity of the members of my group. As each member performs certain tasks, all I had to do was click the up arrow and add to it. IE Jim made 4 widgets yesterday and then made 4 today, I would just hit the up 4 times total 8.
    I guess the good news is when I upgraded to Numbers 3.0, It did not delete Numbers 2.3
    I will continue to use 2.3 until it no longer works, I guess
    Thanks for the replies
