Notify Clients on changes?

Hi,
I have one server an a number x of clients. The server has a method to change a String (for example). If one client call this method and change the string, is it possible to notify all other x clients that something has changed?
Thanks,
Mirco

Not by magic.
This scenario has been worked out many times before. Search the forum.
It requires the Server to build an array of Clients (for callback).

Can server side notify client automatically instead of client refreshing

generally, when we get messages to client, we use refresh requests from server make changes. Dose anyone know in Java has any mechanism that the server can notify client automatically, and dosen't need the client request server initially?
how to implement this?

Thanx, but if not in Http, can java relealize this? For instance, use socket or something else?

Where to Notify About 301 Change After Conversion to HTTPS

Hello,
My website has an approved Podcast channel. Recently for security and other reasons, we have changed the whole website to HTTPS (managed Rackspace), 301 redirection is working fine plus I can manually Edit the XML file to reflect the changes (changes has been deployed 72 hours ago). Support from Rackspace has suggested me to officially notify for the change over email. I will be much helped if any link or email is provided to help me to notify about the change.
(I am not adding the URL here because it is working with 301 and may be, the question will look like a promotive post.)
Thanks in advance,
Abhishek

You don't have to notify anyone regarding Tunes and the iTunes Store. Once the redirect is in place the Store will update and go to the new feed when it next checks the feed - usually within a couple of days. Subscribers will see the change pretty well immediately.
If you are going to use a 301 you should also add the 'itunes:new-feed-url' tag to the new feed so that iTunes and the Store will permanently redirect to the new feed and not be dependent on the 301.
Full details on this page: http://wilmut.uk/move
However https may not be advisable. It certainly used to be the case that the Store would not handle https - I don't know for certain whether it can now do so, though I've seen some evidence that it can - so you should check this with the 301 (which you can presumably remove) before adding the tag.

BPC 5.1 SP3 Client Installs Change EnableNegotiate Registry Key

Just starting with BPC. Our first version is 5.1 SP3 and the server installation was completed successfully.
However, we have found that installing either the Admin or Office client components changes the following windows registry key on the client machine.
Under
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings
EnableNegotiate is set to 0.
This causes the users default home page link to our Sharepoint Intranet to fail with a security error (403.1).
Uninstalling the client components does not reverse the registry key change.
Only manually changing the value of the key back to 1 resolves the issue.
Is there any way to prevent this key from being modified by the client installations?
Why is the registry key changed? Is it critical to the functionality of the client components?
We have not seen any problems in the BPC 5.1 client applications with the EnableNegotiate key set back to 1.
I'm new in these forums. Any input is appreciated.
Regards,
James Littleton

Hi James,
Personally I never have had any issues with this registry key, might be because I do not have many customers using sharepoint.
As you already did, I would change the key and test all functions within BPC extensively, If no problems are found, you could go for it. But be carefull with upgrades of the client software of BPC
Additionaly you could ask support why this key is changed with a client install of BPC.
Instead of a client install via the BPC webportal, a lot of customers are preparing/using custom software packages like SMS. You could reset the registry key with the requred value by using these kind of packages automatically.

Regarding Client Role change in DEV system.

Hi All,
I had some requirement from SapHR they want to do some Holiday calender changes in Sap Level.
and we have only Test Role client in our Dev System. They want me to change the Client Role from Test to Customizing Client.
Kindly let me know if Client Role is changes from TEST to CUSTOMIZING. is there any inconsistany in TMS.
Thanks,
Abdul

Hi,
Run BDLS to change the source system assn. Then check to see if all your transfer structures are active and also your source system is now the correct one. Easiest way is to goto RSA7 on the src system and see where the system is pointing to.

Transacation log in 2 client after Change PI default client (Note 940309)

Hi,
I have changed the PI default client follow the SAP note 940309, and then all the transaction working fine, but then i realize that the xml transaction log save in both client. (001 and new client(220)).
SXMB_MONI
- Monitor for Processed XML Messages (Got data both client).
- Processing Statistics (Only new client 220).
I used PI 7.0 SP 11.
Anybody have same problem with me, Please advise
Regards
Fernand

Hi Fernand,
You mean XML messages?
If Yes
then you see the XML messages in both the clients.
Since the program which selects the messages RSXMB_SELECT_MESSAGES
doesnt take the client into consideration.
If we see the code inside..we will find the following..
    LOOP AT rt_mandt INTO rs_mandt.
      SELECT *
        FROM (lv_master) CLIENT SPECIFIED
        APPENDING TABLE ex_msgtab
        WHERE (where_clause)
        AND   mandt      =    rs_mandt-low
        AND   pid        IN   rt_pid
Correct me if i am wrong.
Cheers,
Sumit
ps : award points if the solution helped u ..

Notified of Property Changes in a Java Object

Hi guys,
Is there a standard mechanims in java where when an object's properties change value, it being notified to the caller. i am typically refering something similar to listeners which the object concerned implments and when reacts to it when the properties change. something similar to a ActionListner or a MouseListener.
I am NOT intrested in UI objects although it could also be considered but my main focus is on POJO type of normal objects in java.

sdbala wrote:
i am quite aware of this but if u read my 5th posting, i simple dont wish to have any code in the target class which notifies the listener, that part should be hidden or at least moved to another place.
ever wondered why i have this weird requirment
well the problem that i have is that i have a framework which basically need to track changes to properties which are implemented by those who using my framework and report those changes to my framework, so that i could proceed with whatever action that i need to take.
therefore i prefer to have less lines of code to be implemented by those who use my framework.Sounds like you want AOP, then, if you really want to keep notification logic out of your classes. We use AOP to capture certain changes in business objects and send them to a data repository, although in a slightly different way: we intercept calls to our persistence layer, rather than changes to the business objects themselves.
The downside is that all of these objects you're tracking will have to be under management of your framework, and you'll be introducing a whole new layer of reflective code to deal with it. Think hard if this is what you really want, really need, before proceeding. The Spring framework will come in very handy for this, btw

Change client after changing system status

first we registered our system as develop. after that we have to change its status to productive. on service.sap.com we changed the system status to productive. in transaction USMM we changed the system type to production. as far as i concern also we had to change the mandat status to productive.how can we do it? can you help me with the documentation or to write how to do it.
thanks in advance

Hi Andrey,
You can change the client status to "Production" in SCC4. Is this what you mean?

Can any one please suggest me some idea.
Thanks in advance

HI
One small Qn.
The note is for changing the client or copying it from one S.system to another sys (Eg:- dev to production)
But in my case i have to change the client within Bw system , So that i can get all the transfer rule from one client to another

Once site is up, can clients make changes?

I'm wondering once Muse is set up and hosted with BC, can a client go in and edit -- as they can do with Word Press?
I see there are some changes in Admin panel, but I don't understand it. I've read quite a bit online but am missing this aspect.
Thanks!

Hi Anita
Yes, your client would be able to access admin section of the site and make changes.
You can create site from Muse or DW , after publishing the site , adding the users as admin to the site will allow them to login to BC backend and make changes.
You can update your site from Muse or DW while working on the site to make changes.

Sanjit

Quantum Client keeps changing to 480p Video!

So I have 3 Quantum clients in my home. On two of them the video keeps changing to 480p and only fitting the 4:3 letterbox size. I go to settings and it says 1080i or 1080p or 720p but it does not matter. The output stays at 480p. So to fix it I have to take out the HDMI from the TV and plug it in to a different input. Then it keeps the settings for a few days but then reverts back to 480p. One is hooked to a new Vizio TV and one is hooked to a new Samsung TV.
Any ideas out there?
Thanks in advance!

Other then to say I am not seeing it with my Samsung "e" series (2012-2013). Mine stays set at 1080P.
Is this happening on the VMS or on the IPC, or both.

Migration Planning: What will happen with clients when changing namespace?

Hello,
We are planning to upgrade our EX2010 enviroment to EX2013.
Sadly our namespace in EX2010 is right now owa2.domain.com. The name owa2 is coming from last migration between ex2003 and ex2010. I'd like to remove this minor flaw if possible.
But what will happen with all the clients and mobile devices which are right now bound to owa2.domain.com? Is it possible to change the name back to owa.domain.com without manual interaction with the clients?
Kind Regards

Hi ,
Based on my knowledge for services like pop,imap and active sync we need to have the manual interaction.Without manual intercation we cannot achieve this.
Same time we need to have the new name on the SAN certificate .
For owa users you can simply communicate the new url via email and then for internal outlook and external outlook connectivity we need to repair the profiles to force the autodiscover service to fetch up the new name.On my experience most of the times repair
will not help.So again your only hope would be reconfiguring the existing profiles.
Note : Most importantly before renaming the host A record on the external and internal dns all you need is to reduce the TTL value for the existing host A record on the name owa2.domain.com.So
that external and internal clients will not have the dns cache for a long period.
Anyhow we will wait for some expert inputs on this case.Because their ideas might be good and different than me.
Thanks & Regards S.Nithyanandham

Using Incquery as EVM for notifying UML papyrus changes

Hi everyone,
I'm using IncQuery for incremental evaluation when model changes.
I have a model listened by IncQueryEngine, my model is UML created by papyrus. I want each time the model changed by Papyrus editor, the incquery should evaluate queries incrementally and notify me the results.
How can I do it? I tried to use ExecutionSchema but it only works if I change my model by Java code not by the Papyrus editor. Say like:
val clz = UMLFactory.eINSTANCE.createClass => [name = "ABC"]
umlModel.packagedElements += clz
This code snippets work and IncQuery notifies me the results but not does by IncQuery? Does Incquery re-evaluate models if they are changed in any manner?
Thanks

Hi,
Quote:This code snippets work and IncQuery notifies me the results but not does by IncQuery? Does Incquery re-evaluate models if they are changed in any manner?
I guess, one of the IncQuery occurences in the first version should be Papyrus; in the remainder I would go on that basis. If it is incorrect, feel free to ask for clarification.
The change notification in EMF-IncQuery works by registering an IncQueryEngine instance as change listener to EMF models (more specifically, Resource/ResourceSets), and then sends further notifications when match sets are changed. E.g., you can verify this in the Query Explorer view from the IncQuery SDK: load your queries and the instance model (from a Papyrus editor), and you can check that the display reacts to model changes automatically.
Behind the scenes, for EMF-IncQuery to work with the changes of the edited model, you have to make sure to initialize the IncQueryEngine on the ResourceSet used by Papyrus, instead of simply opening the model again programmatically (that would result in having a separate in-memory representation of the same model; but the two are not connected in any way). For this to work, you have to write some integration code, e.g. check the current selection of the editor, and find the corresponding resource, or (if I recall correctly), the Papyrus editor implements the IEditingDomainProvider interface, that can also be used to access the editors ResourceSet.

"Poor Signal", "Coverage hole pre alarm for client" after changing from Autonomous to Lightweight infrastruture

Dears,
I use to have wireless infrastructure based on autonomous APs 1142n, auth w/ 802.1x and everything was fine.
My Company decided to implement WLC 5508, and I changed only 2nd floor (2 APs) as lightweight and implement WLC over there as pilot testing...
Now All persons here (around 35 clients) are complaining about disconnections, poor signal...
Both APs are distant each other maximim of 15 meters... Our office has a medium open spaced room, with (20 X 15 meters) only 2 "Pilaster" in the middle of the room.
I am facing this message at WLC logs

Thanks in advance!!!

Actually I am using both APs as lightweight in 2nd floor.
How about this power level? where I can find those parameters ?
At 3rd floor all APs are autonomous, I accessed one of them and find this parameter
CCK Transmitter Power (dBm):           Max
OFDM Transmitter Power (dBm):           Max
Client Power (dBm):                     Max

IP address conflict on Windows 7 clients after change 3560 to 3650

Hi,
after a switch change 3560 to 3650 some Windows 7 clients show a popup with the message "IP address conflict". Because of using manual DHCP (MAC reserve an IP address) i would exclude the possibilitiy of using an duplicate IP address. After search i found this document:
http://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/8021x/116529-problemsolution-product-00.html
I tried the command
ip device tracking probe delay 10
on the 3650 sw. Till now there are no messages with duplicate IP addresses on clients which connected to 3650 sw.
But on on 3560 sw th command does not exist. Anybody who has a similar problem or an idea to solve the problem on the 3560 sw.
The command "sh ip device tracking all" on 3560 shows that ip device tracking is disabled.
Thx for any help.

IOS version 12.2.(46) SE
the suggested command does not exist.
btw the ip address conflict popup appears on clients which are connect to the 3560 too.
any other ideas?
