Using MS Excel as a Source

Question

Hi All,
I want to use excel as a source in OWB. By searching on the web I tried something but no luck it failed. I know that I’m doing something wrong somewhere, I don’t know where am going wrong.
Here I have posting all the system information and steps I followed please correct my mistake.
System Information
Windows Server 2003 R2
Standard x64 Edition
Service Pack 2
Oracle 11.1
Oracle Warehouse Builder 11.1
Microsoft Excel 2007
Steps
1.     Created a DSN named odbc_excel. –actually there were no drivers found in when I followed the usual way to create ODBC connection. By suggestion on the web I ran C:\WINDOWS\SysWOW64 \odbcad32.exe      and created the DSN.
2.     Intit.ora file
Created a init.ora file named initexcel.ora in E:\app\administrator \product\11.1.0\db_1\hs\admin
HS_FDS_CONNECT_INFO = dm_odbc_excel
HS_FDS_TRACE_LEVEL = 1
3.     Listener.ora
+(SID_DESC =+
+(SID_NAME = odbc_excel)+
+(ORACLE_HOME = E:\app\administrator\product\11.1.0\db_1)+
+(PROGRAM = hsodbc)+
+)+
4.     Tnsnames.ora
odbc_excel =
+(DESCRIPTION =+
+(ADDRESS_LIST =+
+(ADDRESS = (PROTOCOL = TCP)(HOST = <server_name>)(PORT = 1521))+
+)+
+(CONNECT_DATA =+
+(SID = odbc_excel)+
+)+
+(HS = OK)     +
+)+
After doing all this I restarted the listener and did a tnsping it was ok.
Then connected to sqlplus and created a database link as below, This also succeeded .
SQL> create database link odbc_excel using 'odbc_excel';
After creating the database link I tried below SELEct statement
          SQL> select * from all_tables@odbc_excel;
     At this point its throwing the error saying
          ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from ODBC_EXCEL
What could be the reason for this?? Is there any special things to consider when doing this in x64 bit environment?????

Hi Sutirtha,
Thank you for the reply. Sorry I couldn't get that doc, It seems there is a backend server issue +(No backend server available for connection: timed out after 10 seconds or idempotent set to OFF. )+. if you could get this pls share with me that will be really great.
and Sutirtha, ianother quick question, does this is totally different way of configuring or the same as above?? if so, then i need to change only PROGRAM = dg4odbc insted of PROGRAM = hsodbc as below right?
+(SID_DESC =+
+(SID_NAME = excel)+
+(ORACLE_HOME = E:\app\administrator\product\11.1.0\db_1)+
+( PROGRAM = hsodbc )+
+)+
(SID_DESC =
(SID_NAME = excel)
(ORACLE_HOME = E:\app\administrator\product\11.1.0\db_1)
( PROGRAM = dg4odbc )
Thank You.
