Question about broker Switchover command

Hi guys
i have one question about switchover cmd . For example, i have 1 primary database called stdby3 and 2 standby databases that are called stdby1 and stdby2.

A simple question about Calculation property

Hello friends at www.oracle.com ,
I tried to create a summary column that sums data from another block, but it has failed - Oracle showed the FRM-30377 error, and it was needed to create a non-database item at the block to be summarized.
This situation has raised one question: if you can't summarize data that comes from another block, why can you choose the block to be summarized at "Summarized block" at Calculation property?
Thanks, and best regards,
Franklin Goncalves Jr.

You can summarize data that comes from another block. But the calculated item must be in a block that has its Single Record property set to Yes.
So you can create the calculated item in a control block, set Single Record to Yes for the control block, and use the calculated item to display a sum of data from another block.

Question about the property of the nested class.

"Nested classes may be declared static. In this case, the nested class has no reference to an enclosing instance"
Can any one demonstrate the above through an code example?? thanks

thanks jverd.
Then why dont you answer my other thread??You have several threads. I've said what I have tosay in all the ones that I know about, am interested
in, and have the time to answer. Last one I lookedat, you were in Monica's very capable hands, so I had
nothing to add.
Thanks!I may not be the sharpest knife in the drawer, but I know better than to piss of her what's gonna administer the dread Blueberry Pie Torture.

Question about 'READBYME' property

We are using XMLForm and we've a problem with portal behaviour.
We want to create a ListShow form which displays only unreaded items in a folder.
Our problem is the following:
- When we use km navigation with a LayoutSet (ConsumerList) readbyme property is not activated until you open the file.
- However, when we have a km navigation iview using RenderListItem, every items are marked as readed when displayed (we display only property id of items). How can I avoid this?.
Thanks in advance.
Damiá

Thanks for your comments,
but our problem is not filtering content but reading xml documents in a folder using ListShow or RenderListItem because readbyme property is set to true when you are only displaying visiblename or id property of items.
--> Is there any possibility for reading file properties using XMLForm throw ListShow or RenderListItem keeping readbyme property false until you access to Show form???.
Correct behaviour of readbyme property in EP is very useful for our pourpose.
Any suggestion?

My understanding about Calc Property

Hello friends, I have a quick question about Calc property. My understanding is Calc=N(that means value is not calculated) would mean same thing as base members. As all non-base members are never calculated, Calc=Y always in non base members, is my understanding correct?
Thanks.

If you have set CALC = Y for a memeber you cannot send data directly to it. CALC property can be Y for the members which are at the parent level or baselevel members for dimension formulas have been defined.
You'll not find much information on this property in help but you can check this link http://help.sap.com/saphelp_bpc70/helpdata/en/4a/88580e1e01465f9ae876ffc46becd2/frameset.htm

Question about the programming of a legend

Hello everybody,
I have a question about the programming of a waveform's legend. I
already asked here in this forum about the legend programming (03)
months ago.
I went satisfied but I ve just noticed that this code
(See Code old_legend_test.llb with main.vi as main function) operates a
little different from my expectances.
Therefore I have a new question and I want to know if it
is possible by labview programming to plot and show, on a waveform
chart, a signal with activ plot superior to zero (0) without to be
obliged to plot and show a signal with activ plot equal to zero (0) or
inferior to the desired activ plot.
I give you an example
of what I m meaning. I have by example 4 signals (Signal 0, 1, 2 and 3)
and each signal corresponds respectively to a channel (Chan1, Chan2,
Chan3, Chan4). I want to control the legend (activ plot, plot name and
plot color) programmatically. Is it possible with labview to plot signal
1 or 2 or 3 or (1, 3) or (2,3) or (1,2,3) or other possible combination
without to active the signal with the corresponding activ plot zero
(0)?
Let see the labview attached data
(new_legend_test.llb with main.vi as main function). When I try to
control the input selected values again I get them back but I don't
understand why they have no effect on the legend of my waveform chart.
Could somebody explain me what I m doing wrong or show me how to get a
correct legend with desired plots? Thank by advance for your assistance.
N.B.
The
both attached data are saved with labview 2009.
Sincerly,PrinceJack

Hi
princejack,
Thanks for
posting on National Instruments forum.
The behavior
you have is completely normal. You can control the number of row displayed in
the legend and this rows are linked to the data you send to your graph. Thus,
if you have 3 arrays of data, let say chan1, chan2 and chan3, you can choose
which data you want to display in your graph using the property node (Active
plot and visible). But for the legend as you send 3 plots there is an array of
the plot name [chan1, chan2, chan3] and you can display 0, 1, 2 or 3 rows of
this array but you cannot control the order in this array! So, to be able to
change this array you have to only send data you need to you graph. I'm not
sure my explanations are clear so I have implemented a simple example doing
that.

Questions about supporting TLF with Halo components in Flex 4.1

We recently decided to upgrade to the Flex 4.1 SDK after a year or so at 3.2. We have been asked to not use the new SPARK components yet because our products would then have a mistmatch of Halo and Spark components in the UI. We have built support for our Halo components to display html through the ".htmlText" property for the Text components. For example, we can display strings such as "<p>Choose <b>one</b> option:</p>". With the upgrade to Flex 4.1 a couple of questions about supporting bi-directional text have come up. My understanding is that in order to support bi-directional text we need to use the Text Layout Framework. Does anyone have a suggestion on how we can utilize the TLF with the Halo components in Flex 4.1? Can we still use the ".htmlText" property somehow or is there a new property that understands the TextFormat markup? We would love to still be able to use the limited html tags that are supported for the "htmlText" property. Is there an option where that syntax is still understood?
Thanks in advance!
David

The halo components use TextField, and the spark components use TLF. Both sets have support for some html markup to import and export text. To use bidi text, you have to use TLF; TextField won't work properly.
It is possible to use TLF to build your own components, and this can work well particularly for applications with specialized needs. But if you need bidi support for advanced components like DataGrid and List, then you should use the spark components.
Thanks!

Question about get web service result in actionscript and convert data format

Hi, All
I have question about how to get dataset from web services
and put it in tree structure. I have 2 questions about this:
1, How can I get data correctly in actionscript?
I have no problem to get data by
<mx:ArrayCollection id="acFolder"
source="{mx.utils.ArrayUtil.toArray(MyGServices.getFolder.lastResult)}"
/>
And display in datagrid.
But when I try to use
public function
handleFolderContents(event:mx.rpc.events.ResultEvent):void{
arData=mx.utils.ArrayUtil.toArray(event.result);
acData=new ArrayCollection(arData);
input.text=acData.getItemAt(0).id;
Seems I can’t get data, it always say:
TypeError: Error #1009: Cannot access a property or method of
a null object reference.
2, how to convert data format
I get data from web service and want to convert it to tree
structure, as mention below:
I get:
<Array>
<id>111</id>
<Name>Production1</Name>
</Array>
<Array>
<id>222</id>
<Name>Production2</Name>
</Array>
Convert to:
<mx:XMLList id="treeData">
<node>
<node label="Production1" data="111">
<node label="Production2" data="222"/>
</node>
</node>
</mx:XMLList>
Please help me.
Thanks.

First, don't specify the package path in the argument
declaration. Instead import the event object:
import mx.rpc.events.ResultEvent;
The docs state this emphatically.
Second, try "lastResult", in place of "result":
arData=mx.utils.ArrayUtil.toArray(event.lastResult); // I am
not positive about this. I maybe recall reading that result was ok
for the event object, but maybe not.
Finally, why do you want to convert the xml? You certainly
could, but it would be a manual process, recursively reading the
existing xml nodes and building the new structure, but again, why?
Just use a labelFunction if necessary to display the nodes as
you wish.

Urgent - Question about logging and debugging.

Hi,
I have a question about the logging and debugging supported by
Weblogic 6.0. From what I understood by reading the documentation
it has classes e.g. NotCatalogLogger class for logging the information.
The class has one method callded
debug() for writing the debugging information. I want to log the
debug messages only in some situation. Can I control this using
some property? Because the documentation says that the debug information
is logged only if application is running in debug mode. Now how
do I change the mode of an application??
Thanks and Reagrds,
Manoj

About application property "Proxy Server"

Hi,
I have a question about the "Proxy Server" property in Shared Components\Definition
Isn't the setting of this property a deployment node issue and not a application specific setting. I would see it similar to the e-mail server settings which are set system wide for an APEX instance. Any reason why it has to be stored for each application?
Thanks
Patrick

Hi Scott,
thanks for your reply. Haven't looked at this from that point of view that sometimes you want to use the proxy and sometimes not.
Currently I just saw it from the point of view of an ISV which is doing the software development on a local systems and then deploys the application to the customer site. For example our environment has another proxy server than the customer site, which is always something which has to be considered when an export/import is done.
A possible solution for your good arguments why someone may wants to have application level/url specific settings and still be able to remove it from the application definition and define it globally on instance level (by the administrator and not the developer) would be to have a look look at how browsers handle the proxy stuff.
What I have seen from IE and FF, they offer the possibility to define a comma delimited list of domains/URL patterns where the proxy should NOT be used. With that additional property the administrator could define that for example for some internal domains/URLs the proxy should not be used.
I would also suggest to replace/enhance the existingAPEX_APPLICATION.G_PROXY_SERVER to have a
FUNCTION get_proxy_server
( p_url IN VARCHAR2 DEFAULT NULL
) RETURN VARCHAR2;where you can pass the URL you want to call and which returns the proxy server property in the case if the URL needs a proxy, otherwise it will return NULL.
I think that could make the proxy handling quite flexible and also easy for the developer if he needs to use the proxy setting in his code.
Maybe John could also contribute some valuable input from a hosting provider point of view.

A question about AdvancedDatagridColumnGroup

Hi guys,
     Just a quick question about AdvancedDatagridColumnGroup, is the children property only allowed to have an AdvancedDatagridColumn on it?
Because what I'm trying to do is in my recursive function I'm trying to create a nested AdvancedDataGridColumnGroup, all good until I set the ADG's groupedColumns to a certain array which is a return array of the recursive function. It throws out an exception something in the groupedValidation function of ADG.
Here's the code that does that
var createColumnGroup:Function = function( group:Array, xml:* ) : Array
                              var ret:Array = new Array;
                              var colGroup:AdvancedDataGridColumnGroup = newAdvancedDataGridColumnGroup;
                              for(var index:int = 0; index < 1; ++index){
                                    var parts:Array = String(group[index]).split(DELIMITER);
                                    if(parts.length){
                                          colGroup = new AdvancedDataGridColumnGroup;
                                          colGroup.headerText = parts[0];
                                          colGroup.children = [];
                                          var curHeader:String = parts[0];
                                          parts.splice(0,1);
                                                                                     //this is the part where I'm trying to nest the advancedDataGridColumnGroup
                                                                                     // what's to be replaced in this line to make a valid nest of ADGColumnGroup?
                                          if( parts.length > 0){
                                                colGroup.children.push( createColumn([parts.join(DELIMITER)], xml));
                                                                            ret.push( colGroup )
                              return ret;
and I call it like this
var gCols:Array = createColumn( colsArr, new XML(_xml.children()[0].toString()));
adg.groupedColumns = gCols;

A question about Oracle 1g R2 Enterprise Edition license

Dear all,
I have a question about Oracle license and I would appreciate if you could kindly help me.
I have installed an Oracle server (11g R2 Enterprise edition) on a linux virtual machine. The pc used for this purpose
is my enterprise laptop (therefore a professional and not a personal Computer). However, I use the this Oracle Server
only for learning purpose, that is, only for running the examples in my Oracle Press books (SQL, PL/SQL and some
administration tasks) just for learning the stuff.
There is absolutely no data related to my enterprise, stored or used on this server. Whenever I want to work with my
enterprise data, I use the Oracle server of the enterprise which has of course the appropriate license. So as I said, I
use this Enterprise server on the virtual machine only for running queries/programs in my Oracle Press books just for
learning and I'm the sole person who uses this server (no remote connection for other users).
The reason for which I needed to install this server on my PC was that our DBA couldn't provide a training environment
for me with all required privileges and functionalities.
Am I supposed to buy a license for this installed Enterprise server on my virtual machine?
Thanks in advance,
Dariyoosh

Question about Local Variables (Multiple answers welcomed!)

A couple of questions about Local Variables
1. Programmers always say: “Do not abuse of Local Variables”. I’d like to know, when and where Local variable are most efficiently used?
2. If I have to create a couple of local variables, is there anyway to “clone” them without going through the repetitive “create/local variables” mouse click each time? (When I try to copy and paste, it creates a new variables instead of the one that I am trying to reproduce)
3. Which is faster in execution: Updating a variable through a) writing to property node/value or b) through local variable
Everyone’s input is welcomed, so if this question is already answered, please
feel free to add additional comments/answers!

1. Use Local Variables in user interface code and no where else. The only exception is using a local variable of a cluster output to define the datatype for a bundle by name node.
2. You can drag copy them then right click to get to a menu of all the currently defined controls and indicators on the VI.
3. B. The problem with A is that it forces a thread switch to the user interface thread--which can take time if you aren't already in it, and it's a very convoluted process under the hood. NI's advice never update indicator values through a property node unless you absolutely, positively can't figure out some other way of doing it.

Question about child "windows"

Hello Everyone,
First, I want to thank everyone who's so graciously taken
their time to answer my previous questions. Because of you, I am
well on my way to developing my very first real world Flex
application. I am consistently astounded at how helpful this
community is and am very thankful to have you all here.
Now, I do have one question about some code that works on the
example but not in real life. I am trying to open a popup window
from a class named composeScreen. In my CDATA section, I have the
following code:
function showWindow(modal) {
var popup = mx.managers.PopUpManager.createPopUp(this,
composeNewMessage, modal, {deferred: true});
Yet, when I save the program, Flex Builder tells me:
"Access of undefined property mx"
Any idea why this is happening?
I've even tried importing the mx.managers.popUpManager class
and it makes no difference.
Please help! This is driving me nuts!
Thanks in Advance,
Anthony

Hi Anthony,
You will have to use popup manager class for this.Here is the
code to give you a lil bit of direction. Call init() function in
the initilize event of the <mx: application> tag
import mx.managers.PopUpManager;
private function init():void{
myWindow = PopUpManager.createPopUp(this, MyWindow, false);
myWindow.visible = false;
myWindow.x = 200;
myWindow.y = 200;
myWindow.height = 100;
private function showWindow():void{
myWindow.visible = true;
myWindow.expand.play();
<mx:Button id="btn" label="click me"
click="showWindow()"/>
When you click on the button your child window must pop
up.
