Connection loss SUM GUI to SL Controller

Hi experts,
I am experiencing an issue that I need to resolve. It is that I lose the connection from SUM GUI (locally) to the SL Controller running on the remote server.
Currently I am doing an upgrade and after some time, e.g. when I have an error and don't notice it immediately, I get a warning message.
"The connection to the SL Controller is down.
The SDT GUI will reestablish the connection, when possible."
On the server I get the following error message:
May 26, 2014 7:49:47 AM [Error]: com.sap.sdt.engine.core.communication.FactoryAlreadyRegisteredException: Factory for key 'com.sap.sdt.engine.core.com

My current assumption is that the firewall drops the connection due to inactivity.
The main issue then is:
although I restart my local SUM GUI and reconnect to the server I can't continue the upgrade because the Buttons are "unclickable" (grey).
Currently I always had to restart SUM including the services on ther server (SL controller).
My question is:
what can I do to avoid this connection loss?
Is there a option to set a "keep alive" to the network connection?
so that the firewall does not validate the connection as idle and drops?
Unfortunately we can't do much about the firewall settings due to security restrictions.
I would be glad to hear from you.
Kind regards,
Niklas

Hi Mathias,
I got an answer from SAP. There is no option that can be executed with STARTUP to solve this.
I already proposed to forward this request to the dev team at SAP
What I am currently doing is:
Start the GUI and keep it open only if I know if there is are Actions coming next, otherwise I close it (only the GUI) and when some time has passed by I logon again to check.
This is a really bad solution, but currently the only one.
Regards,
Niklas

Is this possible: SNC connection from SAP GUI to SAP Router, and ...

Hi,
I have (stupid perhaps) question.
Is this scenario possible:
SNC connection from SAP GUI to SAP Router, and non-SNC connection from SAP Router to SAP System.
I know how to set up scenario like this:
SAP System --- (non-SNC conn) --- saprouter1 --- (SNC conn) --- saprouter2 --- (non-SNC conn) --- SAP GUI.
Best regards,
Marek Majchrowski

Wolfgang,
To be sure myself and Marek understand, can you confirm the different scenarios supported:
Scenario 1:
SAP GUI --- (non SNC conn) --- saprouter1 --- (SNC conn) --- saprouter2 --- (non-SNC conn) --- SAP System
With this scenario, it would be possible for a user to logon using SAP GUI onto the SAP System, but without SAP GUI SNC.
Scenario 2:
SAP GUI --- (SNC conn) --- saprouter1 --- (non SNC conn) --- saprouter2 --- (SNC conn) --- SAP System
With this scenario it would be possible to logon to the SAP System using SAP GUI, and using SNC authentication.
Also, with this scenario the SAP GUI software and SAP System software would consider this to be similar to:
SAP GUI -- (SNC conn) -- SAP System
Scenario 3:
This is the scenario mentioned by Marek in his initial question:
SAP GUI -- (SNC conn) -- saprouter1 -- (non SNC conn) -- SAP System
With this scenario it will not be possible to logon to SAP System using SNC, and only possible if the SAP GUI is configured to not use SNC. In other words the SNC connection between SAP GUI and saprouter1 is available, but cannot be used.
Thanks,
Tim

Windows server 2012 and windows xp remote desktop connection loss

I am having this problem for a month now, and i am stumped with trying to find an answer . I have talked with several network admins in my area and with no luck i have not found a solution. I have a windows server 2012 placed with 5 pcs that are connected
on a local network , those 5 pc's connect to the server via remote desktop. List of pc's:
1x Windows 7
4x Windows XP SP3
All have the latests network drivers, all have the latest version of remote desktop installed. All have been scanned for viruses. All have antivirus software.
Problem is the 4 XP machines lose connection on when connected via remote desktop. If one starts losing connection the other 3 start to lose the connection aswell. The windows 7 machine is not affected by this it works fine.
What have I tried:
Scanning for viruses.
Disabling Firewall and antivirus software.
Updating all drivers.
Did many changes to group policy like keepalives etc.
Turning off SMBv2 SMBv3.
Turning off network adapter Offload settings.
Changed some registry settings like keepalive, smb etc.
Updating every pc and server with all windows updates.
Changed the router and switch.
Port forwarded needed ports like 3389.
Updating remote desktop to 7.0.
I might be forgetting some stuff i will add as i remember anything.
So the thing is this. I use a Windows XP machine from my office I remotely connect to the server via the Internet and I DO NOT experience any connection loss. BUT the XP machines on the local network constantly experience connection loss via remote desktop.
I pinged every Machine from the server via CMD command PING. So when they lose connection the Packets get time outs . Packets get dropped between 1-10 packets when a connection is lost. This packet drop does not occur when using the internet or anything else.
ONLY when connected to the server via remote desktop. The packets get dropped at random intervals.
Problem is I use an XP machine and I am not experiencing any loss of connection , while the XP machines on the local network experience it , but not the windows 7 machine.
Router is ASUS RT-N53 , and switch is Dlink DES-1008D. Server is a Dell PowerEdge T110 II.
Can someone please tell me what can i do to solve this problem?

So today got some word from their office. They were using RDP from 8AM until 12PM all was working fine. Then got back after lunch about 1PM and got a few connection lost errors when they tried using RDP again. Its weird since they didn't have disconnects
in the morning, and started having them after lunch.
Also noticed, that two pc were not using RDP and were disconnected as shown in task manager. And they still got request timeouts.
Maybe this is not a remote desktop issue?

Why do I have Intermittent Wifi Connection Loss during music streaming ?

Hello,
I have an ipad3 and an iPhone 4S and I am getting with both devices interruption of the sound when I send music to the Apple TV. It generally happens after a few minutes. The signal for the wifi is still good and I have still access to the Internet I have tried all the recommendations of the article "iOS: Troubleshooting Wi-Fi networks and connections" but this did not help. I have used several applications for sending music to the Apple TV (music application from Apple and DSAudio from Synology) but I'm getting the same issue. I have also the same issue with the media center application from Bouygues Telecom connecting directly to my internet router. My router is a bbox sensation. I had also the same kind of issue with my old router when sensing photo albums to the internet: I had the error message "your system is running low on ressources". How can I solve these intermittent wifi connection losses ?

Try #5.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Connectivity loss between PLC and Kepware

Hi Experts,
I m working on SAP PCo and PLC connectivity using Kepware.
I m trying to find out ways to find connectivity loss between
1) PLC and kepware
2) kepware and PCo
For 2nd approch,if connectivity loss is there then PCo instance will go in error state and using remote monitoring we can get alert.
But m not able to find any way for 1st approch.
If PLC connection lost then only tag quality in kepware is bad.
Is there any way in PCo expression editor to check tag quality so that i can trigger MII transaction?
Thanks in advance.
Regards,
Neha

To add to Hubrisnsx's comment ... are you provisioned Ethernet or MoCA for the WAN connection?
Edit: Never mind, I see in the first post you said MoCA. So, if the MoCA channel is staying up, then it sounds like it might be something inside the ONT.
Keep in mind that while some Verizon folks do drop by these forums from time to time, that this is primarily are user to user forum where customers can help one another.

Calendar Crashes on connection loss.

Does anyone know why oracle calendar crashes when the connection to the calendar server is lost. This happens for both Mac and Windows. I am using calendar version 9.0.4.2

after much work I have discovered that this is due to power settings on the mac. if you don't turn off the hardrive it seems to work better. This however doesn't explain the corruption issues due to connection loss.

Trying to detect connection loss

I have built a little telnet program which is specialized for a specific telnet supporting server... Everything works just fine except for detecting connection loss...
I am connected to the server using java.net.Socket, data is sent using java.io.PrintStream and data is received using java.io.InputStream...
I have tried having a thread running and looking if the Socket was still connected, but even after closing the server, the Socket keeps returning true when I call Socket.isConnected()... How could I detect the moment when a connection is broken, would it be because the user has a modem connection and gets disconnected or because the server shuts down or any other such reason?

You can detect a dead socket when a write to it fails.
So, you could periodically send "keep alive" messages
to know approximately when it drops.Okay, I had noticed that the PrintStream would set it's error state to true when I try to send a message and the socket is dead, but I hoped I didn't have to wait until that moment... Thanks though! You confirmed me I'll have to do it that way :P

Internet connection loss using Airport Extreme and Netgear DG843

Hello,
I am accessing internet via a Netgear DG834 router (not wifi), connected to an Airport Extreme base station. Most of the time, I can access internet through the Wifi network of the AEB without any problem. But around once a day I am experiencing connection loss and the only way I found to restore it is to reset the Netgear Router by physically unplungging it.
Both the Netgear and the AEB have up to date firmware, so I suspect some kind of problem in my setup, as I am not an expert in setting up networks.
Is it possible that using a Netgear Router connected to the AE (which is also a router if I understand correctly) could cause connection problems ?
I am at a loss, and do not even know how to describe the relevant informations of my current setup. If a kind soul could help me nonetheless, I would be very gratefull.
Mr Pedrito
Powerbook G4 Mac OS X (10.3.9)

Is it possible that using a Netgear Router connected
to the AE (which is also a router if I understand
correctly) could cause connection problems ?
Yes.
Ensure that that the AEBS is configured to not distribute IP addresses.
Also ensure that the AEBS is on a different channel to the DG834G.

Folders being closed upon connection loss?

The issue is that previously it would bring up an error saying that connection was lost and would still show the folders but without any contents, and it would've been possible to do a refresh when you'd have a connection, now it instantly brings to Network folder.
Update:
Previously before the OS reinstall, I've tested what's causing the CPU usage to go up so high using ProcessExplorer, and found out that explorer.exe is using too much services/libraries, mainly ntdll.dll, which is being looped constantly, i.o. ntdll.dll would be copied and copied and copied until you'd restart the process (explorer.exe)

Hello,I'm currently having an issue with a user that is often on the road and obviously it's often that connection is being lost. That person often opens a lot of folders that we have on our local file server, and as soon as his connection is lost it brings him to the "Network" folder. Any idea what could be the issue? Also CPU would rise up to a %100 in total (File explorer .exe consuming approx. 40-60% because explorer.exe has a looping ntdll.dll library being looped in its process).He uses a Dell XPS 13 ultrabook with a four core i7 processor.Before connection loss:After connection loss:

Creating a connection between the GUI and a program's back end

I have created a program (over 50 classes) and am currently a little confused as to how I should connect the back end of my program (the real functionality) to my front end (the GUI). Currently I am thinking about using a list of event listeners in my back end that will announce when certain events have completed and thus front end can handle the updates accordingly.
But I want to ensure that the back end doesn't "know" about the front end. In other words, I would like to ensure that the back end and the front end are as independent/modular as possible.
Can anyone make some suggestions besides event listeners?
Thanks,
Timmers

From what I am able to ascertain from your post, you would advocate using EventListeners in the back end (in same VM) to inform the GUI of changes?
Is this the commonly accepted way of communicating your back end functionality to your front-end (GUI)?
I've read that all EventListeners are part of a single thread. So what happens if two events occur simulataneously in the back-end. Do those events get queued or do some of them get lost?
Thanks,
Tim
If the back-end changes state asynchronously to the
front-end GUI (ie does work in background threads and
then notifies the front-end when something happens),
then you should make it send events when this happens.
The basic concept is the same for CORBA, RMI, JINI,
or running everything in the local VM.
To do this you define a set of events (or maybe you
can use the java.beans.PropertyChangeEvent) and
listener interfaces. The front-end then registers to
receive events (probably via an addXXXListener()
method in the back-end). You would have to have a
class (or classes) in the front-end that implemented
the event listener interfaces to receive the events.
If you are using a distributed technology (CORBA, RMI,
JINI, ...) the concept is the same, but the event
mechanisms are slightly different.
To notify the back-end of state changes in the
front-end you probably can just do plain old method
calls from the front-end to the back-end.

Connectivity loss when roaming from AP to AP

I work for a healthcare organization where nurses use what we refer to as COWS, or carts on wheels. These carts are basically laptops attached to carts that utilize our wireless infrastructure to access patient care applications.
The problem we've been having and working with the application developers on is that, whenever the carts are moved between patient rooms and have to associate with a different AP, the telnet connection that the application uses to establish connectivity is dropped during the short delay in the changeover.
Anyone have any experience with settings that might mitigate this? Far as I know there are no telnet timers that can be adjusted(buffered) to help with this situation, and I'm not certain if anything can be adjusted on the wireless network to help. The "fix" has been to have the user reboot to re-establish the telnet session and then everything's good again.
Any suggestions on things to try?
Thanks.
/rls

I assume these are all on the same SSID and same subnet, i.e. there are no layer 3 roaming issues since you did not mention if you use LWAPP APs. In any case I used to roam all the time with telnet sessions to Cisco switches. If it is dropping the session, it is more likely because of the host system. You could test that by testing to a Cisco device.
A couple of suggestions:
1. Use WPA2 instead of WPA. WPA2 handles roaming better.
2. If you are using XP wireless make sure you have the Microsoft WPA2 update installed. Not necessary if you use another wireless supplicant.
3. Test roaming with a laptop from room to room. If you are loosing more than two pings or so, your roaming sensitivity is not working optimally. Use continuous pings.
4. You could go to fast roaming using CCKM; however, I would make sure the standard roaming method is working correctly before going to the effort of changing everything. Besides, you will need to have a wireless client capable of CCKM. If not, you are out of luck. I had that problem with some of my Windows CE devices. They were too dumb to use CCKM.
5. I did have some Windows CE devices which did not roam properly until I had the roaming sensivity set. I was loosing about 7 pings. This is not normal unless you have a problem.
6. Last resort - but expensive. We had an intermediate server that would hold sessions to SAP due to the potential of the same problem you have. The company that provided it to us was Psion Teklogix. It prevented session loss because a server held the session, not the mobile client. A company like this one should be able to modify the application to your needs if you have money to spend.
Testing is the key I think, but WPA2 would have to help due to the caching of authentications. If you go back to a room you were just in, it should roam faster.

Cannot connect a Java GUI client to an EJB

I am having problems trying to make a Java GUI client connect to an EJB. I am using JRun4.
At first, I tried making the Java GUI client a part of the enterprise application that I am building (of which the EJB is a part of). I included the client as a Java module in the application.xml of the enterprise application.
However, when I try to start the server, containing this application, I get an error saying:
Application authentication required. Incorrect method call.
Now when I try to execute the application from the console, it works fine except when it comes to the part when it has to connect to the EJB. At this point I get an java.lang.reflect.UndeclaredThrowableException. Here's the stack trace:

Since the bean is local, I am using a local reference to the bean in the lookup in the code of the client:
Object o = context.lookup("local/BeanTest")
I tried to use:
Object o = context.lookup("java:comp/env/ejb/BeanTest")
and added an ejb-local-ref in the application-client.xml file of the client. But when I try executing the client in this case, I get an error saying:

I wish someone can help me out with this. My main aim is to get the app client talk to the EJB. Thanks a lot in advance.

Speed connection loss issue since mid December

Morning all here,
We've been having speed problems since the middle of December. We've had BT Total broadband since January 2009 with a very consistant and reliable 3-4 Mbps download speed, but since arround the 13th of Dec when we had a 24 hr power cut the line has never recovered. I've had a good look round the forum here re possible solutions and suggestions, tried all the tricks re the Openreach master socket faceplate, new microfilters etc but its not attainng the service we used to have.

Thanks for the reply imjolly
I haven't done a quiet line test yet, I was trying to leave the hub online as long as possible over xmas to see if things improved, I had tried the hub in the master socket behind the faceplate, but there was no diference between speed tests with it plugged in there instead of the front faceplate socket or the extension it normaly sits in someplace else in the house.
Interestingly, I've just 5 mins ago spoken to my next door neighbour, he's just had an openreach chap in testing the line not half an hour ago. His homehub has turned out to have been fried during the power outage on the 13th Dec., its running slow and unreliably dropping out now and then. Openreach chap took it apart and you could see the damage to the circuit he said.
Now, where do we go from here, that doesn't involve having to speak to BT India I wonder? Should I have a peak inside our router or make the dreded phone call......aaaggghhhh..
Thanks for you attention again.

BBS BEX Query to R3 Transaction - Connect to SAP GUI for HTML not to R3 Backend-TA

Hi Experts,
I try to customize a report-report-interface from a bex query to R3 transaktion fs10n.
I configurated everything in TA RSBBS within BI.
When I start the BBS from the BEX Query a browser session opends, I have to enter the login data for the R3 system an SAP GUI for HTML is started.
Several years ago I tried the same and was connected directly to the Backend-Transaction within R3.
Was there a change within the last year?
Is it possible to configure somewhere in R3 or BW that I want to be tranferred to the Backend-TA and not to open a SAP GUI for HTML?
Can someone help?
Best regards
Mirjam

Hi Stephen,
You should try running one of these transaction iViews using Firefox and have Firebug installed (or use HTTP watch in IE). This might show you why the styles are not being loaded, it could be that since the upgrade something has changed in the SICF configuration settings that is blocking the download of the CSS... that is just a guess, but if you use a tool that will show you the HTTP traffic (like Firebug) then you might get a better idea of what is going on.
Hope this helps,
Simon
