RFC call failing due to UNICODE implementation

Hi
We are trying to connect to a SAP system using the JCO (SAP-JAVA Connectivity). We are passing the user name as an input parameter and in turn the SAP system send back the no. of item (ABAP Type integer) pending for the user name to the java and its inserted/updated in Oracle DB (which does accept the unicode characters).
It was all wokring fine untill the SAP system has been migrated to Unicode upgrade. Now the RFC call is getting failed from our system. On analysis we found with debug, that the user name is not getting accepted by the SAP system and throwing the error -says Exception in thread "main" com.sap.aii.proxy.framework.core.BaseProxyException: Conversion error between two character sets., error key: RFC_ERROR_SYSTEM_FAILURE and at the SAP end the error says "Conversion of "UNAME" from code page 4103 to 4102 is failed". The unicode change in SAP system cannot be reverted back due to some constraints.
Can you please help, how can we pass the user name as encoded in character set 4102 or any other solution so that it can be accepted by SAP and run the Function module and return the data.
Many Thanks
Snehil Joshi

Check RFC destination in Tx SM59. You must have one tab for unicode settings.

RFC call failed: JCO.Server could not find server function 'SET_SLD_DATA'

Hi, All
the system is PI 7.0 EHP1 oraclei Win2003 server, I configured SLD but I run RZ70, having error "RFC call failed: JCO.Server could not find server function 'SET_SLD_DATA' ". I know there are lot of tread about this error, but none of themsolve my problem. all JCO, RFC connections and SDL DATA supplier(VA) seem OK. error message in SM21 is "Could not send SLD data"
detail from SM21
The system could not send the data that has been collected automatical
for the System Landscape Directory (SLD). Check whether the gateway
configured in transaction RZ70 has been started and whether the SLD
bridge has been registered with this gateway.
You can use transaction SM59 to check this in the sending system for t
implemented RFC destinations. The RFC destinations have the standard
names "SLD_UC" for Unicode sending systems and "SLD_NUC" for non-Unico
sending systems. If a different RFC destination has been entered in
RZ70, check this destination instead.
You can use the Gateway Monitor to check the target gateways. In ABAP
systems, this monitor is started with transaction SMGW, or you can use
the external SAP program "gwmon". Check whether the specified gateway
has an active registration.
OF COURSE I checked RFC of SLD_UC and SMGW
any different ideas
Regards
ABH

Hi
Please check the following notes are implemented
Note 906454
Note 907729
You may be aware but if you are not --->RZ70 creates the required SLD* RFCs during runtime - therefore if you have defined these RFCs manually first using the same namespace you can get RFC conflicts which result in a failed submission
Please also check the user in the RFC is known to both systems and has required authorization to write to SLD
Generally with SLD you have to install or select a suitable gateway to handle incoming data supply traffic
Also the gateway you are using has be known to SLD and reflected in RZ70 - i.e these defintions have to be the same
It is also recommended to delete all references to SLD_* RFCs in data supplier and target SLD
after a failed submission attempt to allow RZ70 to recreate these consistently once the above has been checked

Lync server call failed due to network issues

hi,
i receive an error while making a lync call to an internal user
"call failed due to network issues"
i have two ip's installed on My NIC but when i remove one ip of the ip's from
my nic, everything seems to work fine.
Kindly help

Hello Matt,
Hope you keeping well..!!
We are communicating with external customers lync server through federation option setup on our corporate lync server. We have received the federation setting from the customer with SIP address which has been setup on our corporate lync servers after
that we were able to browse the customer contact through corporate lync account.
We were also able to chat with external customer but however voice/video functionality are not working through same session. Whenever we try to dial out external customer lync account it ended with error message "call ended due to network issue".
We have checked the setting from corporate lync servers and network point of view but doesn't find any issue which cause the disconnection to voice/video over lync. Could you pl help or guide with the way.
Thanks

Call Failed due to FADING ??

Hi, I'm hoping someone out there can help me!
I sent my Torch 9810 in to Rogers for repair (phone was overheating). Today they sent me a new replacement, because they couldn't fix the old one....but now the new one can't send or receive calls.
I keep getting the error message "Call Failed due to Fading". Is this a network or a hardware problem?
Rogers said it was the network and tech support said it could be the hardward....any suggestions?
thanx

Hey myrad,
Sorry for the delay in replying.
So if you're using EDGE/GPRS (2G) the phone calls are working perfectly. It sounds to me you have a radio issue now but to make sure it is a radio issue, check the following:
1. Are you using the most up to date device software from www.blackberry.com/update or from Rogers?
2. If not, I suggest updating and then try to reproduce the issue.
3. If you are running the latest software then I suggest contacting Rogers to get a replacement since it is a radio issue.
Let me know if you have any more questions.
Cheers.

Call failed due to network issues

call failed due to network issues lync 2010 client. even when i'm trying to do a test call from my system, same error comes.

Please, share more details on error from logs. Also check firewall ports.
The Media Relay Authentication Service (MRAS) is responsible for notifying the Lync client of the STUN and TURN IP address for ICE. This service
run on UDP port 3478.
To check that the UDP port is open on the firewall between the Internal Lync clients and the Edge server running this service you can use the Microsoft tool PortQry

XI RFC call failing

Hello,
 I am setting up a very simple scenario where I am making a sychronous RFC call to a BAPI in R/3 (Version 4.6c) from an XI Sandbox (Version 7.0).
 I have the RFC Communication channel properly configured, or so I think, and have verified everything else as well. I initiate the message from the Runtime Workbench and it shows with status "Successful" in the Message Monitoring section. However, when I look in SXMB_MONI transaction I am unable to find a response message from the BAPI coming back in the payload. I notice that even though the scenario is synchronous, the "Type" column in the SXMB_MONI transaction results shows it as "Asynchronous". Also, in the message details there is a Payload (which I am sending when I create and send the message from the RWB), in every step, until the Call Adapter step. After that there is no payload in the Call Adapter or the Response steps, just the SOAP Body with the Manifest.
 In the message details I see that the <SAP:Processing Mode> entry is set to "Asynchronous" rather than "Synchronous".
 Does anyone have any idea why this is so?
Thanks,
Murtaza.

Hi Amitabha,
 I looked in the location you suggested and got a list of "Success" messages. These are listed below for you to look at:

2007-06-18 15:17:55 Success The message status set to DLVD.
 The problem that I am seeing is that this is posted under the list of Asychronous Received Messages. Thats something I am just unable to understand. I have a Synchronous Outbound Interface defined and an RFC Communication Channel, which is Synchronous as far as I know. So why is the processing mode for the message being chosen as Asynch? Which config setting have I missed that is causing this problem? I am just unable to find the answer so far.
 I appreciate your help. Please let me know if you have any clues.
Thanks,
Murtaza.

RFC call fails while implementing Inovis EDI. ' NO AUTORITY FOR CONNECTION

Hi All,
We are implementing 'Inovis's' EDI solution. I have narrowed done the error to note 618941. It is telling me to modify the SEC file to allow a RFC_REMOTE_EXEC call.The SEC file came down in the form of a physical file. So I am really not sure what to do here. I don't know where this file should reside. Any ideas?
Thanks!!

I figured it out. Thanks.

RFC Call failing at SAP because of output schema (Response) sent from Biztalk

Hi,
I have deployed the Request/Response message with SAP. Getting RFC Request from SAP in a Request-Response Port. After processing the message, sending it throght same port.
At SAP side the reponse got failed for below error:
Action in response message is
http://Microsoft.LobServices.Sap/2007/03/Rfc/Z_TEST_RFCResponse. Expected Action is
http://Microsoft.LobServices.Sap/2007/03/Rfc/Z_TEST_RFC/response.
I checked my schema file (created by Consume Adapter Services ), there it shows action as
http://Microsoft.LobServices.Sap/2007/03/Rfc/Z_TEST_RFC/response. But still why it is passing RFCResponse at SAP end?
Thanks, Girish R. Patil.

Hello Girish,
Since you are using receive request-response port, it is not possible to mention the action in physical port,
So, You need to assign the Action in Orchestration...For that you use the message assignment shape...inside it write the following code...this will work...!
Response(WCF.Action) = "http://Microsoft.LobServices.Sap/2007/03/Rfc/Z_TEST_RFC/response";
Where Response is name of the response message...!

Naveen.

Oracle stored procedure call failed,but not captured by the error handling

Hi All,
I have a unix shelll script which calls a stored proc in Oracle, the stored proc call failed due to "ORA-01033: ORACLE initialization or shutdown in progress".
But it is not captured in the error handling block, Any ideas why this had happened?
SQL file had : my_test_sql.sql
exec my_proc(..............);
Unix shell script has this call:
sqlplus -s my_user/my_pwd@db1 @my_test_sql.sql
if [[ $? -ne 0 ]]; then
echo "failed"
exit 1
else
echo "success"
fi
If i execute the above shell, I'm getting the following
ERROR:
ORA-01033: ORACLE initialization or shutdown in progress
SP2-0306: Invalid option.
Usage: CONNÝECT¨ Ýlogon¨ ÝAS SYSDBA¨
where <logon> ::= <username>Ý/<password>¨Ý@<connect_identifier>¨ | /
success.
This puzzled me, any pointers?

The $? status variable shows the return code of the last command executed. It will be difficult to determine what the exit status of your sql script is without knowing the script. Do you have any "WHENEVER SQLERROR EXIT" statements in the script?
The ORA-01033 error happens when the database is not open, perhaps in recovery, or startup or shutdown is halted due to a failed or full disk, error in archiving or writing to redo, etc.
