    Hi Krish,

     

     

    Go to following path : oracle/product/network/admin

     

    Please verify following things:

     

     

    1)Make sure that TNSNAMES is listed as  one of the values of the names.directory_path parameter

    in the sqlnet.ora Oracle Net profile.

     

    2)Verify that a tnsnames.ora file exists and is in the proper directory and is accessible.

     

    3)Check that the net service name used as the connect identifier exists in the tnsnames.ora file.

     

    4)Make sure there are no syntax errors anywhere in the tnsnames.ora file.

     

    5)Look for unmatched parentheses or stray characters.Errors in a tnsnames.ora file may make it  unusable.

     

    Please find attached files for reference.

     

     

    Thanks,

     

    Srinvas

    May be the issue is with your Integration Service. Do check the Connect String Given under the Repository setting.

    If the Issue is with the user, then try giving Admin privileges to that user given under Repository setting and then use the same user to setup Integration Service.
