Hi,
The Following Procedure Follow  To Create JCO Destinations.
First You Configure SLD Correctly.If You Have ECC And BW.You Maintaing Two WEBAS ABAP Systems.
You Create WEB AS ABAP System In SLD And Maintain Connection Properties Of ECC.And
Similarly For BW Also.
If You Want To Create JCO Destinations.You Go To Login Portal
Content Administration->Webdynpro->Create JCO Destinatiion
A.General Data -> Specify Model Name,Client And JCO Pool Configuration
B.Specify J2EEE Cluster
C.Destination type
Data Type-> Application DataModel,Dictionary MetaDataMetadata
Destination Type->Load Balancing Or Single Server
D.Specify Either Application Server Or Message Server
E.SecurityUsername,password,confirm password,language
F.SummaryWhole Information
Similarly Metadata Created Follow Same Steps As Above
After Creating JCO Destinations, Go For Maintain JCO Destination And test The JCO Destinations Works Fine Or Not you Con Test.

    Could anybody please suggest what is wrong with this creation?
    Thanks much!!

    Hi Maria,
    Please update the host and sevice file first then check the SLD test and SLD Data supplier in visual admin.
    Also check and verify the data using in the Jco destination creation.
    Hope it will helps

    What may be the issue.

  • AS Java 7.10: Can't create JCO destination 'WD_RFC_METADATA_DEST' in SLD

    Hello,
    I registered my J2EE 7.10 in the central SLD (sldmain.wdf.sap.corp:53000) successfully and created JCO destinations WD_RF_METADATA_DEST + WD_MODELDATA_DEST there. But the deployment of a WD application using Adaptive RFC fails because the above JCO destinations are not found (or access to SLD fails at all?). I didn't find any documentaion on how exactly the 2 destinations must be configured. On the central SLD there's no test/ping function for JCO-destinations! Could it be that my WD-deployer still tries to access a local SLD?
    <b>Root Cause</b>
    The initial exception that caused the request to fail, was:
       <b>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.</b>

    Jen,
    Edit your JCo destinations and make sure you have Metadata as data type.  I am guessing you are getting this error becuase you might have selected Application data as data type.
    Hope this helps

  • Using Ant task wlserver/wlconfig: Received exception while creating connection for pool.

    Hi,
    I am using ant tasks wlserver and wlconfig to configure my weblogic server. while creating a connection pool as shown below
    <target name="jdbcinfo">
    <wlconfig password="weblogic"
    username="weblogic"
    url="${url}"
    <query domain="mydomain" type="Server"
    name="myserver" property="serverbean"
    />
    <create type="JDBCConnectionPool"
    name="jdbcpoolA"
    property="jdbcPoolProp">
    <set value="false"
    attribute="ShrinkingEnabled"
    <set value
    attribute="
    <set value="${serverbean}"
    attribute="Targets"/>
    The JDBCConnectionPool is created as long as I don't specified the attribute "Targets"
    Once I add the target I get the following error
    <JDBC> <BEA-001129> <Received exception while creating connection for pool "poolname" invalid arguments in call>
    Please any help will be greatly appreciated.
    Thanks

    In your applicaion module configurations check if you are using 'JDBC URL' or 'JDBC DataSource'. You should use JDBC DataSource. Then make sure that your deployment descriptor (menu 'Application->Application Properties->Deployment) has the 'Auto Generate ...' checkbox set.

    The status for built-in JCO destinations  WD_MODELDATA_DEST
    WD_RFC_METADATA_DEST is shown as unknown.
    The "Enable" button is also disabled.
    Also i am getting the error "Connection to System Landscape Directory (SLD) could not be opened successfully".
    Can anyone please help me in this.
    Thanks and regards,

    Hi Mayuresh,
    In nwa go to Configuration Management->Infrastructure->SLD Data Supplier Connection->Destinations.
    Create a Destination.
    Ping the destination to check if it is successful.
    After that you can create a JCO Connection.

    Thanking.

    Hello Rajendra,
    Good to hear from u. Let me try to give a soln for this problem of yours.
    I think probably the logon group has not been specified in the backend.If thats the case then do the following:
    Connect to the backend server for which you are trying to create the JCO. Run the transaction SMLG. It will show u the existing logon groups. carry out the following steps if the 'PUBLIC' group is not present in the list of logon groups.
    Click on the create button. In the pop-up, type the logon as 'PUBLIC'. For the instance, select the F4 help and choose the existing instance number. Click on copy and click save. Try running the transaction /nsmlg and now it should show the logon group 'PUBLIC'.
    When you create the JCO connection, it should now show the logon group 'PUBLIC'.
    Regards,
    Prathamesh.
