Client side load balancing and server side load balancing

Hello Team,
I need to know how to set up client and server side load balancing in oracle rac. What all things to be implemented like creating a service, tnsnames.ora settings etc.
And also if i used SCAN ip instead of VIP. how the settings will change.

UIX - unable to turn off client and server side field validation

Hello,
I've scoured the forums for info on how to turn off client / server side field validation, for the very common case of a Cancel button. Here's the use case:
User enters a page displaying records of some kind that can be edited, or an option to create a new one. User clicks create, is taken to a new data entry form. Before entering any data, the user decides he isn't interested, and clicks the cancel button.
The problem I'm having is that I'm getting messages that required fields have no values. I have found several references on this forum that setting the submitButton attribute unvalidated="true" will turn off client side validation. Here's what my submitButton looks like:
<submitButton text="Cancel" event="success" unvalidated="true"/>
But I am still getting errors, such as:
JBO-27014: Attribute ListName in DealerListAppModule.WebDlrListsView1 is required
Now I have also seen references in the forums to turning off server side validation by overriding the validatModelUpdates method in the DataAction. I have done this too. No luck.
Any ideas why this isn't working? I have seen other posts in the forums stating that there were improvements in JDev 10.1.2 that caused a create but not insert, where you could just navigate away from the page you were on, without having to worry about rolling back the create of a new record. I am also not seeing this behavior either. I am using 10.1.2, completely updated, but when I execute a create, if I navigate back from the create page to the original one without saving (i had to fool with this to get it to work because of the validation problems above), I am still seeing the blank, created record in my rowset. I originally created my project in 9.0.5.2, but am now using 10.1.2, and having migrated the project.
So what's the deal? What's the definitive way to turn off both client side and server side validation, and what's the status of this create but not insert functionality?
Brad

Haven't worked with this but possibly this method of "deactivation" is not valid in 11gR2? Have you cross checked that with Oracle support?

What is the difference between jsp :include and server side include

what is the difference between jsp :include and server side include(request dispatcher include method)????
i understand that both request dispatcher include method and jsp:include take dynamic data,so when would one use request dispatcher include and when jsp:include.
Is the usage interchangeable?i believe jsp include is used only for jsp/html but include directive can be used to include servlets ,jsp and html....correct me if i m wrong and
do suggest if u hav ny other diff in this context...

The difference really is: in what format do you want your inclusions? If your environment has many Java developers and only a few designers that focus mainly on, say, Flash, that might push you more towards the server-side include() directive. Or, if you have a large set of pages that receive dynamic content that is displayed in a consistent fashion (such as a workflow header area on a page).
If, on the other hand, you have more web designers, there may be a greater desire to deal in markup rather than Java code. Java developers themselves might prefer to view markup (JSP) that more resembles the eventual output than something occuring in Java code.
Finally, there are considerations of tiering. While it is totally possible to (and I have previously) implement 'view classes' that render markup or generate layout templates, JSP's offer, IMO, a subtle, psychological advantage. By forcing a developer to work in a different format, markup versus Java source, the separation on view from controller and model becomes a bit easier. It is still possible to make mistakes, but if a developer at some point notices, "Wait, I'm in a JSP, should I be importing a java.sql class?", then the choice to use JSP includes has paid off in spades.

This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded

Hello,
When trying to register a custom data flow component (.dll file) to the Global Assembly Cache. I received the following message:
Failure adding assembly to the cache: This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
I think that the problem lies with .NET version (as described in different forums). However the target framework of my project is .NET framework 4 (assembly built by runtime). Where can I see what the currently loaded runtime is?
Regards,
Eddy

Hi Eddy,
You are right. It is caused by that .Net framework 4 is not installed in the server. Please check the installed versions by the following article:
http://msdn.microsoft.com/en-us/library/hh925568(v=vs.110).aspx
If the .Net framework 4 is not installed, please install it at first.
In addition, this issue sounds to be a .Net development related issue. Could you please post it in the appropriate forum in the future.
Thanks,

i serch most of forum i got same answer and i try it but i was not success.
any kind of help is appriciated.
i attached my code(which i implement for testing ) pls reply me

Disable ADF Client and Server side validation during drop down changes

In my ADF Faces there is PanelFormLayout containing dropdown with country code value. Changing the dropdown value should change the layout to different country.
If the data is proper in the form the Layout changes perfectly but if the data is not proper it gives client validation & the layout doesn't get changed.
I want to disable the client/server side validation while changing the dropdown.

Hi Just framing the Question once again -
In my ADF Faces there is PanelFormLayout containing dropdown with country code value. Changing the dropdown value should change the layout to different country.
If the data is proper in the form, the Layout changes perfectly but if the data is not proper it gives client validation & the layout doesn't get changed.
I want to disable the client side validation just for that page or panelformLayout
Issue -
If the data is incorrect on the form, user is able to change the countrycode from the dropdown but the layout doesn't changes because client validation is stopping.
Below is the code -
1) Changing the drop down cause the switcher to call the code - defaultFacet="#{backingBeanScope.AddressComp.displayType}" which changes the layout.
2) But if the data is not correct the country value is getting change with the new Country but the Layout is unable to get change. ADF start showing client validation.
<af:panelGroupLayout id="pglA1" partialTriggers="plcol1:table1 *usCountryId caCountryId*">
     <af:switcher binding="#{backingBeanScope.AddressComp.switcherComp}" defaultFacet="*#{backingBeanScope.AddressComp.displayType}*">

Load balancing and server session

if i configure SLB what will happen if the server initiate connection back to client for example authentication or for a data transfer.
Will the server still use the virtual ip?
example below server3 initiating a session (example authentication) back to client. will it use the virtual ip?
client ------virtual----server1----server3---client

The server will use the VIP if you configure a source group as shown below. You must have a content rule with the same VIP and services.
owner myorganization
content serverfarm
add service server1
add service server2
vip address 172.16.36.58
active
group serverfarm
vip address 172.16.36.58
add service server1
add service server2
active

How can I convert client-side Shared Object in server-side Shared Object?

Hello world....
I have a problem...
I have a program that uses client-side shared Object, like the Example "Ball" il the FMS 3.5 guide: I can move a ball around the stage...
I need to convert this program so I can use server side shared object. This is because I can load the .swf to another .swf and I must to be able to reset, or delete, the properties of my shared object. With client-side sahred object I can't delete or reset the shared object after I loaded my external .swf....
My script is:
private var pointer1_so:SharedObject;
nc=new NetConnection ;
nc.connect (rtmpNow);
nc.addEventListener (NetStatusEvent.NET_STATUS,doSO);
Cerchio=new cerchio ;
addChild (Cerchio);
Cerchio.x=220;
Cerchio.y=280;
Cerchio.addEventListener (MouseEvent.MOUSE_DOWN,beginDrag1);
Cerchio.addEventListener (MouseEvent.MOUSE_UP,endDrag1);
private function doSO (e:NetStatusEvent):void
             good=e.info.code == "NetConnection.Connect.Success";
             if (good)
                   //Shared object
                   pointer1_so=SharedObject.getRemote("point1",nc.uri,false);
                   pointer1_so.connect (nc);
                   pointer1_so.addEventListener (SyncEvent.SYNC,doUpdate1);
private function doUpdate1 (se:SyncEvent):void
             for (var cl1:uint; cl1 < se.changeList.length; cl1++)
                   trace(se.changeList[cl1].code);
                   if (se.changeList[cl1].code == "change")
                        switch (se.changeList[cl1].name)
                             case "xpos" :
                                   Cerchio.x=pointer1_so.data.xpos;
                                   break;
                             case "ypos" :
                                   Cerchio.y=pointer1_so.data.ypos;
                                   break;
private function beginDrag1 (e:MouseEvent)
                 Cerchio.addEventListener (MouseEvent.MOUSE_MOVE,moveMc1);
                 Cerchio.startDrag (false,Rect1);
private function endDrag1 (e:MouseEvent)
                 Cerchio.stopDrag ();
private function moveMc1 (e:MouseEvent)
            e.updateAfterEvent ();
               pointer1_so.setProperty ("xpos",Cerchio.x);
               pointer1_so.setProperty ("ypos",Cerchio.y);
Can someone helps me?
I know I need of a server side script but...
Please...

RequestDispatcher.include and "server-side" include

I have the following code in a servletA. It will dispatch a servletB within the same webapp. As a result, response content of servletB is included to a original servlet's response. Then servletA can add more data to a response before data is sent back to a client.
servletB is called from client-side as normal, and then inside the servletA.
Problem and Question to You:
If I call servletB within servletA, then responses of these two servlets are merged together. This is a problem here.
How can I dispatch servletB >>but then do not want to include<< that response data, but skip it. Only the response of servletA should be sent back to a client?
RequestDispatcher dispatcher =
getServletContext().getRequestDispatcher("/servlet/testServlet?id=AA");
dispatcher.include(
new HttpServletRequestWrapper(env.getRequest()),
new HttpServletResponseWrapper(env.getResponse())
);

Thx and yes, you got it right. Due to a (bad) design, I cannot separate a logic to a standalone bean from servletB and then use that bean. So, I must call it through a url-dispatcher.
If I'm right, I cannot take a reference to servlets from SessionContext object due to a deprecated-and-not-implemented getServlet method.
I was hoping, that using a WrapperXXXX class would solve my problem but it did not. I am not sure about why and when should one use that WrapperXXX classes anyway in a dispatcher calls.
Anyone has a good ideas?

Tabbed panels, Collapsible Panel, and Server Side Include

Hi,
I'm having a problem with the way a Server Side Include inside a Collapsible Panel displays.
Here is how this particular page is set up.
The page has spry tabbed panels.
>>A panel has one overall Collapsible panel (the main product tab)
>>>>Nested in that Collapsible panel are four other collapsible panels (Overview, Features, Screenshots, What's New).
>>>>>>In each of these four collapsible panels is a server side Include that features that category's content
E verything works fine as far as opening and closing is concerned. However, the problem is with the display. The content panel doesn't resize with the Include content, and therefore, the Include content extends outside the border of the content panel.
I'm thinking this is because it is Include content rather than normal content. Is that right?
Do I fix this by changing the overflow value of one the Tabbed Panel CSS styles? If so, which one should I change, and to what value?
Or if that's not how to fix it, can anyone tell me how?
Thanks a lot,
Mike

Hi, I'm using the latest version of Spry. I modified some CSS rules of the tabbed panels, but not the javascript file. I didn't do anything to the Collapsible Panel rules.
Since first posting this thread, I changed the overflow of the Tabbed Panels Content Group CSS rule to "scroll". That did produce a scroll, but I'd much rather have the panel expand. So, I changed it back the way it was.
Here's the page I'm working on. Click the Court Solutions tab to get to the problem panel.
http://www.ptssolutions.com/Test/public_safety_products_3.shtml
It has different results in IE and FireFox, but doesn't work correctly in either.
Thanks a lot for all your help,
Mike

Weirdness involving IE, JSP, data scraping and server-side redirecting

I have a JSP script that validates inputted data. Upon successful input, it will
1) set a cookie
2) Do a data scrape to a URL that points to a servlet that performs server-side actions based upon query string data that is formed from your input
3) Redirect back to itself to ensure cookie availablity and further actions.
If you run this script on Netscape or Firefox, all is well.
If you run this script on IE, while [2] works, it seems to be performing [2] twice, because the actions are duplicated (the actions in [2] consist of placing info into flat files so you can see what is going on).
Does IE have a problem with data scraping + server-side redirection (I am using response.sendRedirect()) that I don't know about?
Thanx
Phil

Agoston_Bejo wrote:
The problem is that right after having logged in, while you're still in the filter, the beans managed by JSF haven't been put into any scope yet. (The faces servlet hasn't been called yet, so it hasn't had the chance to instantiate the managed beans, put them into the appropriate scopes etc.) So it is request scoped? Just create one yourself. I however don't see any benefit/reason for having the logged in user in the request scope ..

Flash and server-side Java interaction

If I have a graphic designer who is going to build a Flash
front-end that needs to interact with server-side Java code running
in a web server (Tomcat), should we be using Flash Remoting with a
front-end that the designer creates with the Flash builder? It
seems like that would be the easiest way for them to build it
rather than having them get into Flex and all that. However, if
there's a better way, please point it out to me, because I've never
tried using any of these Adobe products. Thanks...

hi Naija
If you need to communicate with flash and java , then you
need to move to the flash remoting concept. it the better way to
communicate with the server side scripting language.
