JCo Destination Failing With RFC_Error_COMMUNICATION
Hi Gurus,
We installed a new Bi system with ABAP and JAVA stacks on different hardware and SIDs, now we have problem in integration where JCO BI Meta Data connection is giving following error if I test it. Ping is also failing.
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=host.domain.com GROUP=PUBLIC R3NAME=<SID> MSSERV=sapms<SID> PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR service 'sapms<SID>' unknown TIME Tue Aug 10 05:26:09 201 RELEASE 701 COMPONENT NI (network interface) VERSION 38 RC -3 MODULE nixxhsl.cpp LINE 776 DETAIL NiHsLGetServNo: service name cached as unknown COUNTER 2
I checked sapms<SID> in etc -> services on ABAP host it is defined to message server port, I have added sapms<SID> as 8100 in SLD connection.
All three connections from portal as successful, still JCo destinations are not working.
Note:I have initally added message server port as 3600 in SLD connection where I replaced it to 8100 now, not sure whether this has any impact.
Kindly help.
Thanks
Gopal
Hi,
Please add the sapmsSID entries for both systems (java and abap) in the /etc/services file of BOTH SERVERS. This means that each server should have entries for every system in your landscape.
Additionally, please ensure that this is set to 36<NN> and not 8100 as you mentioned. The reason is that 8100 is ABAP HTTP port, but 36<NN> is message server port. These two are different.
Try this.
Regards,
Shitij

Creates JCO Destination Fails with Error
Hello
I am trying to create a JCO Connection in our EP6-SP9 (Menu Content Administration -> Web Dynpro -> Create JCO Connection). I have not installed a SLD for EP6 but have configured the EP6 to use the SLD of the XI 3.0 SP9. The test connection works OK. The creation of the JCO fails with the message below
An error has occurred:

Edited by: m.genova on May 19, 2009 4:23 PMHello,
The services mapping (name vs. TCPor UDP port number) are specified in /etc/services or the corrsponding file for your OS.
Obviously "sapmsXYZ" is missing there. sapmsXYZ should match the TCP port of the message server.
Kind regards,

Failed to ping JCo destination 'WD_RSDAS_RFC_METADATA_DEST'.
Hello SDNers,
I have Netweaver ABAP trial SPS12 and Netweaver Java Trial SPS14 installed in my laptop. I have also configured SLD and successfully run transaction RZ70. I'm stucked at configuring JCo.
From Web Dynpro Content Administrator, when I ping, it gives me:
Failed to ping JCo destination 'WD_RSDAS_RFC_METADATA_DEST'.
From Web Dynpro Content Administrator, when I test, it gives me:

What's wrong with my config? Help, pls!
Rgds,
Hapizorr Rozi AliasHi,
Just to test, try to connect using SPACE LOGON GROUP
Another tip, verify the property rdisp/autoabaptime on profile of your ABAP Installation.
Try to change it from 0 to 300.

Vijay KalluriHi Vijay,
You need check following thing to resolve this issue.
1. Check the your host file entries for CRM System (Start>Run>enter 'drivers'>etc>hosts)
2. Check SLD test is successfull or not.
3. As per your error message group PUBLIC not found. Check in the CRM system (T-code : SMLG) whether PUBLIC group is available or not.
Then check JCO destination parameter again and test it.
Hope this will helps you.
Thanks

Hi,
when logging in am getting com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'WD_GPMS_RFC_METADATA_DEST' in the SLD.
I had restarted the Server & and also System.
Exception:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'WD_GPMS_RFC_METADATA_DEST' in the SLD. No such JCO destination is defined in the SLD.
Accessing the System Landsape Directory (SLD) failed. Depending on the concrete reason (see root cause) check the following:
is the SLD Supplier in the J2EE engine configured correctly? See the SLD documentation for more details about the SLD and about how to configure it.
are all JCO destinations maintained correctly? Use the preinstalled Web Dynpro Content Admin application to check/edit the destination. Use the Ping and Test functions of the
Content Admin to verify that each destination is properly configured.
Additional information about the System Landscape Directory and the Web Dynpro Content Admin can be found in the SAP Developer Network (SDN) and in the Online Help for the SAP Web Application Server (installed with SAP NetWeaver Developer Studio and available online).
Note: the above hints are only a guess. They are automatically derived from the exception that occurred and therefore can't be guaranteed to address the original problem in all cases.
Please help me resolving it.
Thanks,
HussainHello Hussain,
It looks like your Basis team has added another JCO destination to your Landscape....just check with them and create the jco destination on the portal...to fix it.
Let me know if it helps. -
Dear all,
When i was running a Wec dynpro Application created with The abap Function Modul BAPI_FLIGHT_GETLIST, a error "com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'WD_FLIGHTLIST_RFC_METADATA_DEST' in the SLD. No such JCO destination is defined in the SLD. "
happened. Can someone tell me how to sole this error?Thanks .
Rgds,
Sweet.Hi,
when you are creating Adaptive RFC Model .
in the 2nd step it will ask for 2 things
1.Define the logical system name for model instances
2.Define the logical system name for RFC Metadata.
what ever the names you give here you have to create JCO destinations for that.
Logon to portal.
navigate to content Administartion---->webdynpro
there you have a button "Maintain JCO Destinations".
click on that
In the table you will find WD_FLIGHTLIST_RFC_METADATA_DEST
with status with an icon in red color.
That is indicating that you are JCO destination is not created.
click on create button and follow the below link from page no 25-27
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/355b9c90-0201-0010-d2a8-89fece426526

We migrated Packages from SSIS 2008 to 2012. The Package is working fine in all the environments except in one of our environment.
SSIS 2012 is intermittently failing with below error while importing data from a source table into a Destination table with same exact schema.
Error: 2014-01-28 15:52:05.19
Code: 0x80004005
Source: xxxxxxxx SSIS.Pipeline
Description: Unspecified error
End Error

Description: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft SQL Server Native Client 11.0" Hresult: 0x80004005 Description: "Invalid date format".
End Error
Error: 2014-01-28 15:52:05.19
Code: 0xC020901C
Source: Process xxxxxxxx Load TableName [48]
Description: There was an error with Load TableName.Inputs[OLE DB Destination Input].Columns[Updated] on Load TableName.Inputs[OLE DB Destination Input]. The column status returned was: "Conversion failed because the data value overflowed
the specified type.".
End Error
But when we reorder the column in "Updated" in Destination table, the package is importing data successfully.
This looks like bug to me, Any suggestion?Hi Mohideen,
Based on my research, the issue might be related to one of the following factors:
Memory pressure. Check there is a memory challenge when the issue occurs. In addition, if the package runs in 32-bit runtime on the specific server, use the 64-bit runtime instead.
A known issue with SQL Native Client. As a workaround, use .NET data provider instead of SNAC.
Hope this helps.

Bug: LCDS-180 - [WebLogic 10.1 on Suse9] MxUnit Dynamic destination "SecurityEmployeeUser" test fails with a NullPointerException
QA: Yes
Doc: No
Details:
This prevents the NPE but for non-servlet endpoints you need to be sure to define your users/roles in Weblogic's default security realm. The test was failing because login was failing, most likely because the regression server wasn't fully configured.

I have checked SLD is running and is configured properly , i dont know anything about JCO destinations , this error is giving hint as
Accessing the System Landsape Directory (SLD) failed. Depending on the concrete reason (see root cause) check the following:
is the SLD Supplier in the J2EE engine configured correctly? See the SLD documentation for more details about the SLD and about how to configure it.
are all JCO destinations maintained correctly? Use the preinstalled Web Dynpro Content Admin application to check/edit the destination. Use the Ping and Test functions of the Content Admin to
I have gone through Blog
Configuring SLD in Sneak Preview SAP NetWeaver '04 Sneak and all settings looks fine.
Please make note this system has come recently under our maintainence and i am not much aware what exactly previous Administrator performed , But SLD is running fine.
Can somebody help at earliest?
Best Regards,
AjitRHi,
Have you defined the JCO destinations in Web Dynpro Content Admin.
If you havent, look at these link and configure the JCO Destinations required for ESS.

Failed to resolve JCO destination name in the SLD
I have installed the ESS/MSS business package, and configured all JCO connections. testing the JCO connections is successful. I can connect to the SLD from the WebDynpro administrator.
when I run the ESS/MSS, I get the following error:
"com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'SAP_R3_HumanResources_MetaData' in the SLD. No such JCO destination is defined in the SLD. "Hello,
when I installed ESS/MSS there were two JCO Connections:
SAP_R3_HumanResources_Metadata
SAP_R3_HumanResources_MetaData
Pay attention to the right spelling! I mean the second one is the right one.

Failed to resolve JCO destination name 'WD_RFC_METADATA_DEST'
Hi Experts,
I am using NWDS 7.1 ehp1 version and i developed a sample application here to retreive the data from r/3.
when i try to execute the application it's giving the following error..
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'WD_RFC_METADATA_DEST' in the SLD. No such JCO destination is defined in the SLD.
can anybody help me to solve this issue..
thanks,
viswaHi,
First test your destination.
'WD_RFC_METADATA_DEST'
Login as an Administrator, then click on "Check SLD", Check if if in your System Landscape Directory Both the ABAP technical system and a Web AS JAVA. are created or not????
If not create the two systems.
If they are already created then,
click on "Maintain JCo Destinations" and there you can see all the applications and their corrosponding metadatas. If JCo is already created then status comes in green color or else status comes in red color.
Check if these JCos are created or not....
If they are not created then create the JCo destinations.
If they are already created then Ping them....
But as per your error, it seems like you haven't maintained JCo destinations.

Any suggestion what is problem?Hi Wooi,
Please create JCO destination 'SAP_R3_SelfServiceGenerics_MetaData' and 'SAP_R3_SelfServiceGenerics_MetaDataFIN' for Metadata. First check SLD working fine or not. if the SLD is fine then update SLD data supplier in the visual administrator.
As you metioned the JCO are grayed out. then you need to update host and service file in server location. the do SLD and SLD data supplier test.
Once JCO connection test will successful then your issue will resolved.
Hope it will helps
