Why i cant change log_buffer parameter dynamically

hi , why dont i can change the log_buffer parameter dynamically by alter system command.
ORA-02095: specified initialization parameter cannot be modified

It's because log_buffer has DML images. Oracle can't risk redo information, since it's a main source for recovery. At any cost oracle don't want log_buffer to be corrupted. This why log_buffer in most of the OS gets the GUARD PAGE protection.

I am hoping your Oracle Consultant know what he's talking about.
According to Oracle Performance Guide,
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14211/memory.htm#sthref654
"On most systems, sizing the log buffer larger than 1M does not provide any performance benefit. Increasing the log buffer size does not have any negative implications on performance or recoverability. It merely uses extra memory.
The best method to determine if bigger redo buffer is needed is
SELECT NAME, VALUE
FROM V$SYSSTAT
WHERE NAME = 'redo buffer allocation retries';
The value of redo buffer allocation retries should be near zero over an interval. If this value increments consistently, then processes have had to wait for space in the redo log buffer. The wait can be caused by the log buffer being too small or by checkpointing. Increase the size of the redo log buffer, if necessary, by changing the value of the initialization parameter LOG_BUFFER. The value of this parameter is expressed in bytes. Alternatively, improve the checkpointing or archiving process.
Other than that, hight log file sync event indicate you need faster disk for your redo logfiles. However, please also post your commits per second and redo per second from your AWR report.
100M redo logs might be small for your environment.

I cant change payment method in Apple Ipad, because it tells me bla bla u had problems with billing bla bla. I DO NOT HAVE ANY PROBLEMS with billing bla bla. WHY i cant change my payment card????????? WHY I CANNOT CHANGE REGION? FROM UK TO RUSSIAN?????

Cant change details, cant change region, cant download apps, cant change payment card, cant upload apps.

Apps are always associated with the Apple ID and password used to download or purchase them. If you have begun using a different Apple ID, when those old apps require an update, you will have to enter the old Apple ID and password that used use to originally download those apps.
You can stop this requirement by deleted those old apps and purchase or download them again with your current Apple ID.

Change Movie Parameter Dynamically

This is more of a javascript question but I figure
actionscript folks would have run across this before.
Is there a way, using javascrit , to change a movie's
parameters, dynamically, AFTER the movie has been embeded?
I know you can change some parameters (see links below) but
specifically I am looking to change the wmode parameter.
I have looked at:
http://www.adobe.com/support/flash/publishexport/scriptingwithflash/
and
http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_12059
But this documentation appears to be 3 to 6 years old and I
am hoping things have changed. Any easter eggs out there realtive
to this that anyone has found?

For access over VPN you need:
management-access inside
and don't forget:
ssh inside
http inside
I'm guessing you forgot to grant ASDM (http/https) access to the IP addresses used by the VPN? Can you SSH? If not, that is your problem to solve first.

How to change any parameter in gradient?

Why I can not change any parameter in an existing gradient?
For example: one pageitem have gradient and i can see (in vba locals) its parameters:
FillColor.Angles
FillColor.Matrix
FillColor.Origin
FillColor.Length
But nothing change.

setListVOBoundContainerColumn method can be used on poplist bean to set value from current row of table dynamically.

How to calculate the Percent change in a dynamic

hi All,
I'm trying to get the percent increase/change of two dynamic
colums. In my report, the user has a checkbox where he can select two colums to calculate the percent growth.
My DataSet is PilarName, Calification(is a decimal value) and Period (this is a string). I created the Matrix this way:
PilarName [Period]
[PilarName] [Calification]
Which give me these values:
So, now I need to create another column to calculate the percentage change between these two colums. I tried this:
I added a Adjacent column group for Period column and I grouped by the calculated column "ColumnDiff". Add the following expression.
=(SUM(Fields!Calificacion.Value)- Previous(SUM(Fields!Calificacion.Value),"ColumnDiff"))/Previous(SUM(Fields!Calificacion.Value),"ColumnDiff")
After that I get:
I'm getting the sum of the two columns instead.
Any clue about what I'm doing wrong? Please help me, I've been looking for the answer but any solution works for me.
Luis Carlos

Hi Luis,
According to your description, you have a report with different dynamic columns. Now what you want is show your user percentage growth in your matrix report after your user select two of those columns (I think you may use parameter to achieve your “checkbox”
function). Is my understanding correct?
In Reporting Service, we can’t calculate dynamic columns with our build-in arrogation functions. So we need to add custom code into our report, and call those functions which defined in custom code in our expression. We have tested your scenario in our local
environment. Here are steps and screenshots for your reference.
Go to your Report Properties, add the custom code below into your report:
Dim Shared Num1 As Double
Dim shared Num2 As Double
Public Function GetCalification(Calification as Double,Type as String,Type2 as String)
If Type = Type2 Then
Num1=Calification
Else
Num2=Calification
End If
Return Calification
End Function
Public Function GetPec()
Return (Num2-Num1)/Num1
End function
Create a matrix. Put PilarName into Row field, put Period into Column field. In Data field, put the expression below into the textbox:
=Code.GetCalification(Fields!Calification.Value,Fields!Period.Value,Parameters!Period.Value(0))
In our sample report, we created a parameter (named Period) for selecting two columns. You can replace “Parameters!Period.Value(0)” with your own parameter.
Add an outside column at right (%Growth), put the expression below into the textbox:
=Code.GetPec()
Save and preview. The matrix and result looks like below:

How change NLS_NUMERIC_CHARACTERS parameter for load external table

Hi,
I use this version:
OWB 11gR2
Database 11gR2
Parameter NLS_NUMERIC_CHARACTERS Database ., Instance ,.
When I created database with wizard and in this moment I don't set spanish language, later I changed this parameters in instance parameters.
Now I want load data from a file to external table, but I've an error when I try load data with decimal point.
why does it use the database parameter instead of instance parameter?
Is possible to change this parameter?
Cheers
Marisol

At this moment , this is not possible . You can see metalink note ID 268906.1.
It says:
Currently, external tables always use the setting of NLS_NUMERIC_CHARACTERS
+at the database level.+

I can not transfer date from one hard drive to another, I keep getting an error because I have two of the same file names and one file name is in caps and I cant change the file name

can not transfer date from one hard drive to another, I keep getting an error because I have two of the same file names and one file name is in caps and I cant change the file name. My original external has an error and needs to be reformatted but I dont want to lose this informations its my entire Itunes library.

Sounds like the source drive is formatted as case sensitive and the destination drive is not. The preferred format for OS X is case insensitive unless there is a compelling reason to go case sensitive.
Why can't you change the filename? Is it because the source drive is having problems? If so is this happening with only one or two or a few files? If so the best thing would be to copy those over individually and then rename them on the destination drive.
If it is more then you can do manually and you can't change the name on the source you will have to reformat the destination as case sensitive.
Btw this group is for discussion of the Support Communities itself, you;d do better posting to Lion group. I'll see if a host will move it.

[Q] how to change lines in dynamic textfield

Hi, I am struggling to change lines of loaded text from xml.
Basically I wrote few sentences in one child of xml file but
when i loaded it to dynamic textfield I cant change the lines.
(i tried with <br> /n both didnt work, textfield was
multilined)
thank you for your time

how much text are we talking about?
What parameters have you set for the text field? multilane?
html?
What size is your text field?
Just some basic questions to think about. I actually link to
an external text file if I have too much text to deal with. However
I usually write text box's in the code.
You already have the text field, so you shouldn't need the
create command, which I probably got wrong anyway.
my_TXT.createTextFeild(name,depth, x, y, width, hight)
my_TXT = new textformat ("my_format")
my_format.size = 27
my_format.mutilne = ture
my_TXT.html = true
my_TXT.htmltxt = "bla bla <b>bla</b>"
my_TXT.format(my_format)
Again I can't be sure I got all the names right, but
that’s about how it works.
Again you don't have to use that, but to get the text to work
you at least need mutiline to be on. To get html to work, you need
html to be on, and you need to use the htmltxt to write it to the
txt field in code. However I’m not 100% on if that’s
the correct way to write it.

When is the next update for iphone carrier setting?I cant change my carrier to 2g!!!There is only 3g or LTE available for me.

Carrier Settings are dependent entirely on your carrier. 2G is old outdated and slow etc, most carriers are phasing out their 2G service. You would need to ask your carrier when they plan on releasing a new update.
Why on earth do you want to set your iPhone to 2G? It will automatically switch to 2G if 3G is not available, and 2G is found.

Why we cant use commit in trigger, can any one give proper explanation

Why we cant use commit in trigger, can any one give proper explanation

You shouldn't use a commit in a trigger if it's part of the same transaction as the action happening on the table.
Eg. Suppose you have a table that stores details of orders, and it has a trigger that updates the stock table.
If a customer comes along and creates an order but decides part way through that actually, they don't want the order after all, the transaction is rolled back.
If you don't put a commit in the transaction, then the stock table details remain unchanged - no order, so no stock reduction. If, however, you forced the commit to happen in the trigger, you now have no order, but the stock table details have changed.
That's not what you want to happen!
Sometimes it does make sense to have a commit in the trigger, but this is very much the exception. If you come across a table mutating error, it usually means that you have a problem with your design and that you need to rethink it, NOT bodge it by using autonomous_transaction and a commit.
Of course, the times when you'd use triggers should be few and far between - the above example is NOT how I'd code an orders-stock transaction; I'd have some PL/SQL that handled the transaction, rather than direct inserts onto the table.

Msprot: cant read profile parameter rdisp/mshost

Hi
When I run : msprot -name <SID> -l it returns:
cant read profile parameter rdisp/mshost
rdisp/mshost is set in the default profile to : sapms<SID>
in etc/services sapms<SID> is assigined to <port_number>/tcp
If you change rdisp/mshost to the port number rather than sapms<SID> it works....but we don't want to change the parameter to the port number.
Thanks
Jim

Thanks.....i've being testing the command....it's like it can't read the default profile...
if i use mshost switch it complain it can't read msserv.....once I use both switch it runs ok....
I changed default profile to 777 just to test if it was a permissions issue but that didn't make a difference.
Thanks for the note but that seems to be dealing with windows...i'm working on sun...tried it on linux also and get
the same problem....
Cheers
