Oracle parameter - how to reset to the default value ?

Hi
I saw once how to reset the init.ora parameter to the default value with "ALTER SYSTEM" clause. I've read the manual but I couldn't find it.
Do you know how to do it?
Regards

ALTER SYSTEM set <parameter> = <value>; - if not using SP file. and also change in int file.
ALTER SYSTEM set <parameter> = <value> scope=<memory or spfile or both> ; - if using SP file.
Only some parameters can be changed this way not all.

How can I get the default value of a particular preference in FireFox?.
I know I can see the default value for some of the preferences in about:config but, I need a programatic way to get the default value.
I see some that there are values for preferences in firefox.cs but I am not certain that these are being used as the default values for preferences. prefs.js in user's profile only has the updated values and not the default values.
Any help towards acheiving this programtically is greatly appreciated.
If the default values are stored in a file, kindly let me know the format in which it is stored for me to parse it programatically.

Dear Friend,
Here when you have the callableSattement as ?=proc(?), the first ? is an output parameter. So you should register it as out parameter using registeroutparameter.
Then you can get the value from the outparameter using callablestatement.getXXX().
Try that way.

How can I change the default value of a command ?

I want to be able to change the default value of a comand when the vi
is running. (I know how to do that with a right click when the vi is
not running).
In fact I would like the user of the vi to be able to choose a new default value for a command.
How can I do that ?

You can't do this on a running VI. If you have an idle VI, you can open a reference to that VI and use an invoke node with the Make Current Values Default method, but that will only work in LV (i.e. not in an EXE) and will affect all the controls. What you can do is save the values to a file and load them when the program starts. OpenG's File I/O package includes some VIs which will help you with that.

How do I set the default value to 0 in a property with "money" as the type?

I have an entity with several properties with the "Money" data type. I also have a Money property with a "computed" value that shows the sum of the other money type properties. However, a total will not display if any of the other
fields are left with a null value. Is there way to make the default value set to "0"? I am using c#. Thank you.

Mark, there's a very basic .NET method on every nullable object:
GetValueOrDefault
EDIT: Now I see...please avoid duplicating
questions...
To be clear:
Put GetValueOrDefault on every nullable field used inside your 'TotalDue_Compute' sub
You don't need to define 'TotalDue' as Nullable anymore

I've figured out I can change
"*DefaultXRAccountingSystem: PickOne" to "*DefaultXRAccountingSystem: XSA"
enabling accounting.
then I change
"*DefaultXRAccountingPrompt: Prompt" to "*DefaultXRAccountingPrompt: DoNotPrompt"
so I'm not prompted to enter the accounting code on print
what I haven't figure out is how to set the value of the accounting user id.
I suspect that
*XRFeature XRAccountingUserID: "string 0 20 Accounting"
is declaring the accounting user id, and might be a place to set the accounting ID. But i'm not sure how to set it.
or maybe it should be set at
*XRAccountingSystem XSA/Xerox Standard Accounting or Auditron: "" ?
any suggestions? ideas?

Hi TeenTitan
I may have a problem simular to yours with a KM bizhub C451 with accounting turned on from Mac OX 10.6 + 10.7 + 10.8 machines.
On some machines we can go into printer settings just to check that all user/password settings are ok (without changing anything) and then we can print one job. It looks like the system forgets the user name and password unless we go into printer settings each time we want to print.
I was thinking of putting in the user/password in the PPD just like you.
I was wondering if you ever found a solution ?

How can i implement the default value for this variable?

In one of our Stored procs,we have a variable RECS_TO_DELETE, which determines the number of records to delete from various DELETEs that happen within this proc.
The value for RECS_TO_DELETE variable should be obtained from a configuration table sys_config
select
rec_num into RECS_TO_DELETE
from sys_config
where
sys_code=55;
But if something goes wrong with sys_config table or the above SELECT INTO, our client wants to makes sure that RECS_TO_DELETE should have a default value of 1000.
In the code, how will i implement having this default value of 1000 for RECS_TO_DELETE variable in case the above SELECT INTO fails for some reason.

Hi,
You have to assign a value before the execution...
DECLARE
    RECS_TO_DELETE NUMBER(9) := 1000;
BEGIN
    SELECT rec_num
    INTO   RECS_TO_DELETE
    FROM   sys_config
    WHERE sys_code = 55;
    DBMS_OUTPUT.put_line(RECS_TO_DELETE);
EXCEPTION
    WHEN NO_DATA_FOUND THEN
       DBMS_OUTPUT.put_line(RECS_TO_DELETE);
END;

How can I change the default value in IT0009?

Right now in our system when we create a new IT0009 entry, several fields are defaulted such as the payee name, bank country, and currency (field WAERS). But in table T588Z I can not find anything defined for IT0009. Now even I create entries in T588Z ex. as
0009 WAERS 06 10 W P0009-WAERS='USDN'
the currency still shows up as 'USD' when I create a new record. Can anyone tell me where the field 'WAERS' is defaulted as 'USD' and how can I control this?
Thank you very much.
Best regards,
Johnson

Hi Johnson,
Correct me if I am wrong,You need to default a value, so i guees you would need to use the feature P0009 not the dynamic action. If you could let meknow the current structure of the p0009 feature, may b i could help you figure the could-be structure of the p0009 to default the required value.

How do I set the default text in a bound textbox?

How do I set the default value of a bound textbox when the AddNewItem button on the MenuStrip is clicked?
I have the following code (see below), but for some reason it does work when I put the code in the
AddNewItem_Click event; however, it does work if I put it in the
Form's Load Event. The statement in question is Me.txtBusUsagePct.Text = 100.
What am I doing wrong? Why can't I set the default text in the AddNewItem_Click
event?
Private Sub BindingNavigatorAddNewItem_Click(sender As Object, e As EventArgs) Handles BindingNavigatorAddNewItem.Click
Me.txtBusUsagePct.Text = "100"
End Sub

Hello,
Here I am using mocked up data but the important thing is after loading the data. Requires on the form a BindingNavigator and two text boxes.
Public Class Form1
WithEvents bsData As New BindingSource
Private Sub Form1_Load(
ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles MyBase.Load
Using MockedData As New DataTable()
MockedData.Columns.AddRange(New DataColumn() _
New DataColumn("PartName", GetType(String)),
New DataColumn("partqty", GetType(Int32))
MockedData.Rows.Add(New Object() {"Part A", 100})
MockedData.Rows.Add(New Object() {"Part 99", 34})
MockedData.Rows.Add(New Object() {"Part B", 4})
bsData.DataSource = MockedData
End Using
CType(bsData.DataSource, DataTable).AcceptChanges()
BindingNavigator1.BindingSource = bsData
TextBox1.DataBindings.Add("Text", bsData, "Partname")
TextBox2.DataBindings.Add("Text", bsData, "partqty")
End Sub
Private Sub bsData_AddingNew(
ByVal sender As Object,
ByVal e As System.ComponentModel.AddingNewEventArgs) _
Handles bsData.AddingNew
Dim dv As DataView = TryCast(bsData.List, DataView)
Dim rv As DataRowView = dv.AddNew()
rv("PartName") = "(new)"
rv("partqty") = 0
e.NewObject = rv
bsData.MoveLast()
End Sub
End Class

How do I set ical default values in lion?

I have just upgraded to Lion and so far, so good. In the new iCal, how do I set the default values? In the old version, when you clicked on the calendar, the default value was a 1 hour meeting around the current time of day. The new version defaults to an all-day meeting. I like the old way better, or best would be to have it as a preference.
Is there a way to set this that I'm not seeing?

Mike,
It sounds to me like you are using the "Month" view for that entry.
Default event creation in Month view results in an all day event.
Lion iCal Help (Add events to a calendar) says: "Add a new event in Month view by double-clicking within the day you want the event to appear. Enter a name and time duration for the event in the event’s title field, and then press Return."
Try entering "Meeting at 9am"...that will create a one hour event named Meeting.

My tab default is1.25 which is too big for the A5 document I'm working on, how do I change the default tab so that I don't have to reset each individual line?

Hi Hannah,
Inspector > Text > Tabs Button > Tab Settings > Default Tabs.
To set a tab stop on the go, click in the ruler.
If you can't see the ruler, Menu > View > Show Rulers.
To set tab stops for lines (paragraphs) you have already typed, select those paragraphs and set them all at once.
Also, have a look at Menu > Pages > Preferences > Rulers.

How to make a subscription use the default value for a parameter

Hi everyone,
I need to use the CreateSubscription method and have this new subscription use a default value for certain parameter. How can I do this?

Hi Marianne,
I have to create the subscription programatically, which is different from what you mention. To further clarify my challenge:
I have three parameters in a report: date-interval (string), start-date (date), end-date (date). If the user selects for example "last week" as the date-interval, the DEFAULT values for the other two are as follows:
Code Snippet
start-date=DateSerial(Year(Today),Month(Today),Day(Today)-Weekday(Today)-6)
end-date=DateSerial(Year(Today),Month(Today),Day(Today)-Weekday(Today)-1)
The user can then select intervals like "today", "yestarday", "this month" etc, and the other two parameters are calculated based on that date-interval parameter. Now, If I programatically create a subscription to a report that contains these three parameters and set a value of "last week" for the date-interval parameter, the subscription stores the fixed days (say september 10 to september 16) producing a report of the same week every time the subscription is run and not updating the correct interval to LAST-WEEK!. What should I put as the value for start-date and end-date when I create the subscription to have these two params get the DEFAULT calculated value based on the third param date-interval?
Hope to have been more clear now.

How to reset all the icon spacing etc in Finder back to default?

I have tried to set back to the default values but it's still isn't quite the same as before -- the horizontal spacing is correct but not the vertical one. Is there a way to reset the icon spacing as default?
Thank you.

John Guo wrote:

Your not done... That will set the user defined defaults back to the Apple defined defaults. To get your folders to use the Apple defined defaults, open up a folder showing the wrong spacing and press Command-J to bring up the View Options window. At the bottom of the View Options window there is a button that says "Use as Defaults". Press the Option Key and the "Use as Defaults" button will change to "Restore to Defaults". Click the "Restore to Defaults" button and the folder will go back to the Apple defined default settings. You might need to Control-click on the window for the folder and select "Clean Up" to get things lined up. Good luck...

How we can find out the default value of the initialization parameters

Hi All,
How we can find out the default value of the initilization parameters from oracle database.
Thanks
Shiju

Hi,
you can find currently used parameter values v$parameter and v$parameter2.
if default values is different real values then you can see alert.log.
because in alert.log you will see non default values, rests is default.

SRM 4.0- How to set the default values for product type (01) only for SC

The radio button Service should not be visible.
Also for search help (e.g. search for internal products) where a search should only be possible for product type 01 (goods). The system should not display the product type and internally always search for goods only.
How to set the default values for product type (01) only for SC
We needs to use Search help BBPH_PRODUCT which having parameter PRODUCT_TYPE
Here we can set defalut value 01 but it is not correct one since same search help is using several places.
We need to limit the search help results only for SC.
Kindly help out me ASAP.

The easiest way to set defautl values is to edit the batch class.
Goto the characteiristic and go to update values.
In here you probably have something like 0 - 100 as a spec range.
On the next line enter the default value within this range. At the end of the line, click in the box in the column labelled "D". This indicates the defautl value for the characteristic.
If you need to you can do this in the material classification view as well.
Just to be clear, these values will only show up in the batch record. You can not have defautl values in resutls recording screens.
