Communication between domain models

Hi All,
I have an event that is being dispatched from a domain model (DomainModelEvent.RESULT) which needs to be received from another domain model (DomainModel2.play()). I've read in various forums the use of patterns such as Messenger or Presenter being helpful for PM-to-PM or PM-to-Domain communication, but not Domain-to-Domain. Since I'm using Cairngorm, should I just have these domains dispatch a CaringormEvent that a command object can handle. This creates dependencies between the model and the Cairngorm framework, but is that so bad? Since it's a DOMAIN model, it is dependent to the application (which is in Cairngorm) anyway? Does anyone have any insights on this?

Hi there,
Do you have a motivation for the domain1 not referencing domain2? Maybe the guideline Options in Loose Coupling could be useful. Checkout the Guidelines section.
Best,
Alex

Communication issues between domain controllers

Hi everyone,
I am experiencing some problems in communication between domain controllers in our organization
We have three domain controllers, one of them is a Windows 2003 server service pack 2 which is physical (controller A), another which is Windows 2008 Service Pack 2 (controller B), also physical, and a third one (controller C) which is a Windows 2008
service pack 1 and is virtual.
I have problems with this last DC, it won't respond to pings, or DNS query. I can't Access it by remote desktop client even when it is enabled. I cannot update it, it prompts error messages if I try to do so.
This problems are solved if I reboot it, it will work fine some hours or days, but not much longer. I have checked event viewer and I didn't found any message about this.
I read some time ago it would be great to have a DC in a virtual machine, so I did it, but is it right?
Do you know what might be going on with it? would depromoting it and seting it up again the best solución?
Thank you very much.
Best regards.
David.

This sounds like a NIC issue, which is odd since it is a virtual machine. Have you checked the host for any logs about the client?
I think the first thing I would do is destroy the current virtual NIC card and add a new one. Since this has nothing to do with Active Directory I would also suggest you post this in a forum of for the Host (VMWare or Hyper-V).

Is in PI7.1 possible asynchronous communication between SOAP and ABAPProxy?

Hi,
when method execute_asynchronous has disapeared since XI/PI 7.1, is
there still way how to use ABAP proxy in asynchronous way?
We need to build asynchronous connection SOAP->PI->ABAP_Proxy.
In PI, both interfaces are defined as asynchronous (outbound for SOAP and
inbound for ABAP Proxy).
Despite of this fact, when message is sent, it is processed
synchronous way.
I have set breakpoint in my implementation of method for ABAP Proxy
message processing. When message is sent and breakpoint is reached,
whole connection stays open (between SOAP and PI and between PI and
ABAP Proxy) and waits for processing method (the breakpointed one) to
return. Only when processing method returns, is connection finelly
closed.
If i understand it correctly, this is synchronous behavior. In
asynchronous behavior, as i understand it, should be connection
between PI and ABAP Proxy of application server closed immediately
after message has been delivered. This mean before my processing
method is even called.
The same could be said about SOAP and PI communication. Connection
should be closed immediately after PI has received message. From
definition of asynchronous communication of PI is obvious, that PI
should receive message correctly and close connection to sender system
even when receiver is unreachable. It should deliver message later
when, receiver system is back on line. So why it keeps connection to
sender system open while it waits for receiver?
Why is this happening, when both interfaces are defined as
asynchronous? Could be the reason for this, if APPLICATION
ACKNOWLEDGEMENT is set on by default? If so, how can i change it
to SYSTEM ACKNOWLEDGEMENT, or disable it at all?
Or is this kind of asynchronous communication even possible since
XI/PI 7.1 ?
Processing of message we are sending can take some time, so we dont
want connection pending open while waiting for finish of
processing. Thats the reason why we have chose asynchronous model to
use.

Quote from How to Use the J2EE SOAP Adapter:
"If you select Best Effort, the Web service client will receive a response
message in the SOAP body. Otherwise, the Web service client will not receive a
response message if no error occurs."
"if no error occurs" - that is the problem. In either case he still
waits if some error occure or not. I dont want it. Once PI has
received message, I want the connection with sender to be closed. If
there will be error in communication between PI and reciever, I want
to see it only in PI log. That mean no notification to sender to be
send about that error.
Is that possible?

Communication between two MVC's

Hi.
I want a communication between two MVC's, offcourse in one project.
What I have:
MainWindowView (MVC)
|
+--> MenuView (MVC)In my Menu MVC there is a button Logout. When this one is pressed the model had to tell the MainWIndowView that he can close.
How can I do this?
Statix.

I have a solution... but I don't know if this is a neat one..
This is my MenuModel:
          case 3:
               MainWindowController.closeMainWindow();
               LoginModel loginModel = new LoginModel();
               LoginController loginController = new LoginController(loginModel);
               break;
          ...This one communicates directly with a public static void closeMainWindow () method which disposes the view (JFrame)
     public static void closeMainWindow (){
          mvcView.dispose();
     }     Is this a solution so I stick to the MVC pattern??? I hope so... I wouldn't know another way...
Thanks in advance!

Communication between Edge and Transport servers in Exchange 2010

hi,
Its a strange communication error that I'm having here, though there are no service outages observed till now.
When I try to test-servicehealth from any HUB server to any Edge server, it always says some error (refer the error below), but the services are all running perfectly fine. even restarting of RPC service and WMI service not helped either.
likewise when I run get-exchangeserver -server <edgeserver> | fl name,*exchangeadminversion*, this result shows exchange version is 14.2, but the actual version of Edge server is 14.3 (SP3 with RU8.
This means the communication between my Edge server to other exchange server having some issues? or is it a conman behavior that i no need to worry?
Error message:
Couldn't get information about the Exchange services using Windows Management Instrumentation (WMI) due to error: WMI e
xception occurred on server 'Edgeserver.domain.com': The RPC server is unavailable. (Exception from HRESULT: 0x800706B
A)
+ CategoryInfo : ReadError: (:) [Test-ServiceHealth], ServiceHealthWmiFailureException
+ FullyQualifiedErrorId : EBBF3409,Microsoft.Exchange.Monitoring.TestServiceHealth

I think I got an answer for this question.
The version number displayed is the one that was written to Active Directory at the time the Edge subscription was created. Because EdgeSync is a one way process, the version number does not update as you update the Edge Transport server to newer versions.
If you want the version number to reflect the current value, recreate the Edge subscription

Migrate servers between domains

Hello
We need to plan an AD domain migration to an already existing domain - i.e. not a new domain - for dozens of servers hosting different roles and am looking for some general pointers for what we should be aware of.
We cannot use ADMT (for internal political reasons) and cannot use external tools, e.g. Quest (for cost reasons)
The roles on the servers include:
Domain controllers, IIS, SQL, CRM, VMWare Virtual Center - plus other bespoke applications.
I know there will NOT be a "one size fits all" process for every server (or even every application) but was hoping someone could provide general information for the apps mentioned above.
e.g. should we not even consider moving the server(s) between domains but rather build a new server and reinstall the application ? If rebuilding a server is NOT an option for any reason, CAN we move the application server(s) to the
other domain without issues ?
I realise this is a very complex set of tasks but, as I said, just looking for some general information to give us a starting point.
Thanks

>>>CAN we move the application server(s) to the other domain without issues ?
It depends on your authentication and permission model. Where are the users and groups? ACL on these servers from a different domain?
Please provide more information.

Bug: _global vars between domains

Hey
I submitted a bug report on _global variables, and i just
wanted to hear your opinions.
Scenario 1
1. MovieA loads MovieB from SAME domain
2 Both MovieA and MovieB contain a _global variable
Comclusion/Result:
Both MovieA and Movie B adapts the _global variables
Scenario 2
1. MovieA loads MovieB from DIFFERENT domain
2. Both MovieA and MovieB uses
System.security.allowDomain("*")
3. Both MovieA and MovieB contains a _global variable
Comclusion/Result:
Both MovieA and MovieB CAN NOT access/read eachothers _global
variable.
The help file says:
quote:
The Flash Player version 7 and later security sandbox
enforces restrictions when accessing global variables from SWF
files loaded from separate security domains For more
information, see Understanding Security.
I clearly read that as , you should be able to control the
usage between domains , (just like any other scripting operating
with domain policy )
It fails nomatter what, even with
System.security.allowDomain("*") AND crossdomain.xml policy file.

Looking to this Oracle Doc >> http://docs.oracle.com/cd/E24329_01/web.1211/e24375/basics.htm#BRDGE128
"Typical tasks required to manage a messaging bridge using the Administration Console include
Creating a trusted security relationship. See "Configuring Domains for Inter-Domain Transactions" in Programming JTA for Oracle WebLogic Server"
And, clicking the link to Configuring Domains for Inter-Domain Transactions, there's two types of communications:
Inter-domain—The transaction communication is between servers participating in transactions that are not in the same domain.
Intra-domain—The transaction communication is between servers participating in transactions within the same domain
Check the rest of the doc to know how to configure each type, and apply the one that matches your case..
Hope it helps

Communication between Best Buy and Apple

Where is the communication between these two companies? It's frustrating to have NO CLUE if a phone will come in a day or in 5 weeks. Who at Apple is deciding what they end to what stores? Obviously, Best Buy has to pay for the phones. There has to be some sort of communication.
Would it really be that hard for someone high up in Best Buy to communicate with Apple? Maybe a list from each store of their orders and what they are waiting on. Give that to Apple. Apple can give some sort of answer. Exepect this much in this time frame... expect this much later. I mean, something. Instead of leaving everyone in the dark, completely.
Someone at Best Buy corporate has to have SOME clue how Apple is shipping and to what stores. To say no one has no clue at all, is nuts. And if it's true... Best Buy needs to get a clue. DO SOME WORK FOR YOUR CUSTOMERS. At least get some truth, so if we need to go elsewhere, we can. It would be better for both sides.

Apparently since they come on UPS, they don't know when the shipments are coming in or how much. Which I think is bull.
If that's the case, what I want to know is HOW do they know they received the amount they were expecting? If they don't know how much they're getting or when they're getting a shipment, then what's stopping the delivery man from stealing a box, and they wouldn't know any better? Maybe the higher up manager's know, and they aren't allowed to reveal that info, but there has to be a checks system in there somewhere verifying the stock received.

Communication between iViews

How to realize communication between two iViews of the same window but not the same portal page? I tried with using firing portal events but this doesnt seem to work with Mozilla Firefox. Do you have any other ideas?
The sending iView is a portal application the receiving iView a Web Dynpro for ABAP application (so I cant use JavaScript, I guess).
Thanks!
René
Edited by: Rene Guenther on Jan 10, 2008 3:29 PM

Hi Mrkvicka,
To enable communication between iviews you need to use the EPCF .
You can raise an event in the component of the first iview and define an OnClick event.
this event you can subscribe from the other iview
Refer to this link to get a more clear picture
DropDown Selection and EPCF
also refer to
EPCF
hope this helps,

Communication between jsp and abstractportalcomponent

Hello All
Communication between jsp and abstractPortalComponent.
jsp contains one input text field and one submit button.
when the user clicks on submit button it will call the component and that input value will
display in same jsp page.
how this communication will happen?
Rgrds
Sri

Hi Srikanth,
In the JAVA File,
OnSubmit Event,
String inputvalue ;
InputField myInputField = (InputField) getComponentByName("Input_Field_ID");
if (myInputField != null) {
               inputvalue = myInputField.getValueAsDataType().toString();
request.putValue("textvalue", inputvalue);
request is IPORTALCOMPONENTREQUEST Object.
In JSP File,   to retreive the value,
<%
String textstring = (String) ComponentRequest.getValue("textvalue");
%>
In PORTALAPP.XML File,
<component name="component name">
      <component-config>
        <property name="ClassName" value="classname"/>
        <property name="SafetyLevel" value="no_safety"/>
      </component-config>
      <component-profile>
        <property name="tagLib" value="/SERVICE/htmlb/taglib/htmlb.tld"/>
      </component-profile>
    </component>
Using the code above, You can pass and read values between abstract portal component and Jsp Page.
Instead of this, I suggest you to use JSPDYNPAGE Component for Data Exchange.
Check the [Link|http://help.sap.com/saphelp_nw2004s/helpdata/de/ce/e0a341354ca309e10000000a155106/frameset.htm].

Communication between : AP and WLAN controller

Hi,
The communication between AP and WLAN Controller is ( Data and Control ) UDP.
Source port 1024 and destination port 12222 and 12223. Actually which device listen to which port or both should listen as control and data can be generated from both the devices.
How does the user ( wireless client) traffic is switched - if user traffic is a TCP traffic. It will be sent to WLANC and then WLANC forwards it to respective VLAN or default gateway ( depending upon the destination in the packet ).
Please explain / share the experience.
any link on cisco.com
Thanka in advance
Subodh

"the LWAPP Control and Data messages are encapsulated in UDP packets that are carried over the IP network. The only requirement is established IP connectivity between the access points and the WLC. The LWAPP tunnel uses the access point's IP address and the WLC's AP Manager interface IP address as endpoints. The AP Manager interface is explained in further detail in the
implementation section. On the access point side, both LWAPP Control and Data messages use an ephemeral port that is derived from a hash of the access point MAC address as the UDP port. On the WLC side, LWAPP Data messages always use UDP port 12222. On the WLC side, LWAPP Control messages always use UDP port 12223.
The mechanics and sequencing of Layer 3 LWAPP are similar to Layer 2 LWAPP except that the packets are carried in UDP packets instead of being encapsulated in Ethernet frames."

Communication between HP eprint and Google Cloud Print

Hi,
the communication between HP eprint and Google Cloud Print seems to be broken. At least for me.
The documents do get printed when I print vio Chrome browser or Cloud Print dashboard -- but the status in cloud print remains as "submitted". It seems like somehow the HP eprint status doen't get reported back to cloud print. In HP eprintcenter the log says "printed".
Well, I wonder who will take care of this problem ... (Hope it will not result in fingerpointing only ...)
Thanks for your support!
Best,
George
This question was solved.
View Solution.

Are you able to log back in later and the status at Google Cloud print update to reflect the true outcome of the print job? Or does it just remain as "submitted". Otherwise, if it is printing and showing in the log at ePrint Center (EPC) as printed, the issue would not be on the ePrint side but on Google's

Communication between Lab view and Controller via USB

USB communication between C8051F320 and Lab View. I try doing methods given in the NI site(http://zone.ni.com/devzone/cda/tut/p/id/4478) and atlast, it gives me error −1073807302 so if any one can answer my question please do post me the details concerned to it.

My devices show up as NI-VISA USB but I'm not sure if that makes a difference and I'm not using USB RAW either. One thing that you can run is a VISA Property node like below and see what it reports. Also, what version of VISA are you using? If you are not using 4.0, you can download it from http://digital.ni.com/softlib.nsf/webcategories/85256410006C055586256BBB002C0E91?opendocument&node=1....

Communication between the DNS/DHCP Manager and OES Server

No communication between the DNS/DHCP Manager Console and OES server (status,start,stop)
The screenshot shows the tab "DHCP (OES Linux)" in the DNS / DHCP Manager console
in the bottom of the image it shows the state of the DHCP servers.
allDHCP.JPG
The dhcp service is started on all these servers
You can see that the status is known only for four servers.
The button "start/stop DHCP service" works fine on this servers and
the dhcp service can be canceled and also restarted
But the status of the "dhcp service" is not recognized for all the other DHCP servers
and so we can not start or stop dhcp service on these servers.
All servers were installed at different times (last three years) with OES11 and
are upgraded to OES11SP2 with all patches.
The server keto (DHCP_keto) is a new installation OES11SP2 few days ago.
All OES servers were set up identically from me. LDAP, LUM, DMS, DHCP works fine.
Which service on the OES server is responsible for
communication (status indicator) between the DNS/DHCP Manager and the OES serve?
How the status query is performed by the DNS/DHCP Manager?
How can I test the communication to the server on the client (console)?
Which configurationfiles I should be compare on the server?
Thanks in advance

Communication between two clients

In Java Networking, communication between server-client or bwtween server-multiple clients is general. But How will be the communication between two cients, means two clients can send & receive messages to & from each other(being guided by server).

Sorry,
I didn't get your reply clearly.
I want, if Server is running, and two clients(two instance of a same program) are opened, whatever message(string)client1 send to Server,then the Server needs to send those to client2.Again, the some response should come from client2 to client1 thru Server.
How can I implement this?
If you have idea, or some sample code about this, please let me know.
Regards.
