SLD configuration - JCO connection with SAP Router

Hi,
I installed the new Sneak Preview SP11 Java Edition including SAP Portal. I tried to run an own Web Dynpro Application with RFC-Access on a R/3 System.
Unfortunately I was not able to get the JCO Connection to run. The R/3 System is reached via SAP Router. I am a little bit confused, because with the last Sneak Preview (SP6 or SP7) this application was running without problems. Of course I thought that this can't be. So I uninstalled SP11 and installed the old version (SP7). I configured the JCO-connection, no problems.
Now I know that this is not my mistake (hopefully ).
If I configured a JCO-connection in SP11 and tried to PING, the first PING was ok. After testing the connection with user, the PING failed. The testing with user returns something like "user or password are not accepted".
Any ideas?
Best regards
Renald

In your SLD configuration, what do you have as your Logon Group under the message server config. Is it "PUBLIC". if so, then the user id needs to belong to that Logon Group in the system.

Hello,
I want a connecton from XI 3.0 to R/3 with SAP Router.
But if i want to import the RFCs i become no connection.
I Edit Software Component Version, but there is it not possible to set any Sap Router String.
For Connection Data you can only set System, Client, Message Server and
Group.
I have also test to write the Router String before the Message Server IP without any sucess. Not enough Place to write the holfe Path in the Field.
I become no connection to the R/3 to import the RFCs.

DBACOCKPIT Connection for SAP systems with SAP Router

Hello!
We are trying to integrate all the remote SAP systems and their databases (primarily Oracle) into DBACOCKPIT of SAP Solution Manager 7.1.
Our SAP Solution Manager is running on Windows with Oracle 11.2.0.2
The most SAP systems (Unix and Windows) can only be reached from SAP Solution Manger over the SAP Router connection.
It means no direct ping from Solution Manager server to the Server of managed system will work.
Question
Is it possible to integrate such SAP systems (with SAP Router) into DBACOCKPIT of Solution Manager?
According to sap note 1265134 only the DBCON-connection will be required.
By doing so (tcode SOLMAN_SETUP), we get TNS errors.
Do we miss some additional steps (adapting tnsnames.ora of SOLMAN with the entry of managed system), etc.?
Thank you!
regards

Systems can be reached via SM59, then what's the problem ?
In fact, this 'is' the standard procedure. This is as normal as you could have Solution manager in same 'network' with rest of the remote systems.
Answer should be yes, you can manage several remote sap systems from sap solution manager dbacockpit.

Error in creating JCo connection with destination type'Load-Balanced Con'

Hi,
I am working on webdynpro application(NW 04s), i need to connect with the backend system(ECC 6.0) using model.I configured my SLD and created technical system successfully.
The technical system got created with an error:
CIM_ERR_ALREADY_EXISTS: Instance already exists: SAP_BCApplicationServer.CreationClassName="SAP_BCApplicationServer",Name="ID1.Number.01.HostName.ahsides"
But the system got created so I proceeded with Jco connection creation:
I need to create 2 Jco connections for this,
First with Data Type 'Application Data' & Destination Type 'Single-Server connection'. Second with Data Type 'Data Dictionary' & Destination type 'Load-balanced Connection'.
The first Jco with 'Single-Server connection' got created successfully and ping and test is also successfull.
The second Jco connection with 'Load-Balanced Connection' got created successfull but it is throwing error while pinging and testing.
Ping Error : Failed to ping JCo destination 'WD_EMPLOYEE_RFC_METADATA_DEST'.
Test Error : com.sap.mw.jco.JCO$Exception: (102) JCO_ERROR_COMMUNICATION: JCO.Client not connected in repository call
Please help me in this.This problem was with 'Load-Balanced Connection' only.

Hi,
Have you taken a look at the file %windir%\system32\drivers\etc\services?
If you haven't, try and find the line sapms<sid>, where sid is de SID of the system you-re trying to reach.
If the line isn't there write it down like this.
sapms<sid> 36<nr>/tcp
That works for me.

How can i fix my wifi connection with my router

how can i fix my wifi connection with my router?

I think I'm having a similar problem, my wifi disconnects when a bluetooth device is connected to the MBA.
I have a MacBook Air (13-inch, Mid 2012) with WiFi and Apple Trackpad. I'm unable to use the trackpad(bluetooth) and wifi at the same time. If I turn off the trackpad then the wifi works fine and if I shutoff the wifi then the trackpad works fine. This configuration was working fine prior to upgrading to Yosemite.
I experienced the same problem at home and at the office.
Additional test:
I turned off the bluetooth trackpad and connected my bluetooth headphones to the MBA. The wifi disconnected as soon as I paired the headphones with the MBA.
I have had no problems with the MBA's keyboard or integrated trackpad.

Quality Server not connect through SAP Routing String

Hi,
When remotely access client SAP through SAP routing string in Quality Server it shows error message as
"timeout occured

Here GUI version is 7.1(where from connecting). Client SAP version is ECC 5.0 and they use GUI 6.4 version. But Development server is being connected through SAP Routing String.

You might want to check following things:
Can you do a ping to the IP address you specified?
Is the data correct (ip, host, system number,...)?
Is the gateway with system number 00 running on the server?
Did you install the SAP RFC SDK dll's?

Problem in configuring IPv6 interface with default Router lifetime.

I'm facing Problem in configuring IPv6 interface with default
Router lifetime through a router advertisement.
I'm also see an unusual behavior that even after configuring accept_rtadv=0,
the ipv6 address is configured.
Please help in out .

Mac OS 9 does not support IPv6. While you can have IPv6 on your network, a Macintosh running Mac OS 9.2.2 or earlier cannot make connections to services using this network protocol.
To use IPv6 on a Macintosh, you need Mac OS X 10.1 or later (as far as I know).

1) I deleted bridge-utils, netcfg
2) I edited /etc/hostapd/hostapd.conf:
interface=wlan0
#bridge=br0
edited /etc/dnsmasq.conf:
interface=wlan0
dhcp-range=192.168.0.2,192.168.0.255,255.255.255.0,24h
and edited /etc/rc.local:
ifconfig wlan0 192.168.0.1 netmask 255.255.255.0
ifconfig wlan0 up
3) I added in autostart these daemons: hostapd, dnsmasq and iptables.
Profit!

Not able to connect with my router, but other networks work ok.

I have a 2d generation iPod Touch. I can't connect to my home network that operates on a DLink DIR-628 router. However I can connect to other access points with no trouble at all. When my iPod tries to connect with my router, it asks for my password and I enter the password I think is correct, but it won't accept it. When I check the router web page there is no password visible. Does the problem lie with the Router or with the iPod Touch? I have three other computers and two wireless printers that are operating through the router with no problem at all.

Have you tried:
- Resetting your iPod:
- Resetting network settings on the iPod: Setting>General>reset>Reet Network Settins
- Powering off and then back on your router

C # Aplication connection with SAP Windows CE

Hi,
I have a problem with an aplication that I've made in Visual Studio C#. The problem is the next:
I've made an aplication that connects with SAP and passes some data. This aplication works well on any computer but I've got a problem when I tried tu convert the code and use it in a hand help pc. The version of OS of the hand held pc is Windows CE 5.0 and the error that I get when I execute my software is something related with the COM and the Class ID, the error says the next:
"COM object with CLSID '{B24944D6-1501-11CF-8981-0000E8A49FA0}' cannot be created due to the following error: Class not registered ."
I think that the problem could be with some dll that I don't have installed on the hand held pc but I don't really know which or what exactly.
Does anyome know anything about all of these??
Thanks.

Hi Julien,
To do the connection on a normal PC I include in the code the next references: SAPLogonCtrl and SAPFunctionsOCX.
Once they are included in my code I do the next:
private SAPLogonCtrl.SAPLogonControlClass saplogon;
private SAPLogonCtrl.Connection conexion;
private SAPFunctionsClass func = new SAPFunctionsClass();
SAPFunctionsOCX.IFunction sapfu = null;
Then I have a method to connect to SAP and other to pass the data. The one that connects to SAP is:
private void Connect_SAP()
saplogon = new SAPLogonCtrl.SAPLogonControlClass();
saplogon.User = usuSAP;//Usuario SAP.
saplogon.Password = passSAP;//Contraseña del usuario de SAP.
saplogon.Language = "ES";//Idioma.
saplogon.Client = cliSAP;//Mandante a través del cual nos vamos a comunicar con SAP.
saplogon.ApplicationServer = "10.10.20." + serSAP;//Ip en donde se encuetra el Servidor de SAP.
saplogon.System = sysSAP;//Entorno al que vamos a acceder.
saplogon.SystemNumber = System.Convert.ToInt16(num_Sis);
conexion = (SAPLogonCtrl.Connection)saplogon.NewConnection();
conexion.Logon(0, true);
DateTime hora = DateTime.Now;
if (conexion.Logon(0, true)==true)
MessageBox.Show("Conectado a SAP");
*Error1.Text += "SAP:Conexion establecida con exito" + "
Write_log("SAP", "Conexion establecida con exito",hora);
else
MessageBox.Show("No establecida conexión con SAP");
*Error1.Text += "SAP:No se ha establecido la conexion con exito" + "
Write_log("SAP", "No se ha establecido la conexion con exito", hora);
func.Connection = conexion;
if (sysSAP == "PRO")
labelSystema.Text = "Productivo";
else
labelSystema.Text = "Desarrollo";
Now the problem is that I want to use these code to make the same connection on a handheld PC but it doesn't work, when I execute the compilation on the handheld PC I get the next error:
"COM object with CLSID '{B24944D6-1501-11CF-8981-0000E8A49FA0}' cannot be created due to the following error: Class not registered ."
When this happens the compilation stops and it shos me the line in the code thar points to:
saplogon = new SAPLogonCtrl.SAPLogonControlClass();
I don't know why I get this error, I think that it could by that I'm not using the correct dll for a handheld PC that uses a Windows CE 5.0 O.S.. My question is: do I have to get a new dll that works on a handheld PC? or is it not working for any other reasson.
Thanks for your help.

Loss of connection with Belkin router

I have been using a Belkin N450DB router with my Westell modem for over 2 months. Everything was fine until 4 days ago when my router lost connection. I have tried the self heal with the router and the troubleshooting with the modem. I currently have internet with just the modem hooked up but have lost connection 3-4 times this way over the past 4 days. I have no connection with the router connected now. It says wire unplugged. I was thinking it was the router but have found out another DSL customer in my town has the exact same issue and he has a different router. Did Verison reset some security programs that won't allow my router to connect or is Verison DSL having issues we are not aware of in Greenwood, DE? It is just strange that two residences are experiencing the same issues in different areas.

#1 What is the model of that Westell modem?
#2 When you said

are you saying that the router says that or are you saying your OS (and Version - for example Windows XP) is saying that?

Why my IPAD2 sometimes loose connection with my router and I need to enter again the WPA password?

Why when my IPAD2 loose connection with the router sometime I need to enter again WPA2 password?

same problem here.
MBA (latest os), even my ip5 (latest ios) & ipm (also latest ios) looses the connecntion.
Ive tried to figure out what causes the problem - neither my xbox360 nor (and i guessed they will be the problem) the pcs here...
the connecntion runs well.. switching also (MBA-IP5-IPM).. but not for longer than an hour.. or even minutes. When the connection looses a high-frequency noise is followed by silence. A restart fix that problem and all devices streaming well... but not for long...
any suggestions?
