Hi all,

before I smash my head against the wall..........

I am trying to execute an external procedure defined in a C .dll.

I have set up my tnsnames/listener.ora as following :

# C:\ORANT\NET80\ADMIN\TNSNAMES.ORA Configurationfile :C:\ORANT\net80\admin\tnsnames.ora
# Generated by Oracle Net8 Assistant

Tcp-loopback.world =
  (DESCRIPTION =
    (ADDRESS_LIST =

        (ADDRESS =


          (PROTOCOL = TCP)

          (Host = 127.0.0.1)

          (Port = 1521)

        )

    )
    (CONNECT_DATA = (SID = ORCL)
    )
  )
extproc_connection_data.world =
  (DESCRIPTION =
    (ADDRESS =

        (PROTOCOL = IPC)
        (KEY = ORCL)

    )
    (CONNECT_DATA = (SID = extproc)
    )
  )         

# C:\ORANT\NET80\ADMIN\LISTENER.ORA Configuration File:C:\ORANT\net80\admin\listener.ora

LISTENER =
  (ADDRESS_LIST =

        (ADDRESS=


          (PROTOCOL= IPC)

          (KEY= oracle.world)

        )
        (ADDRESS=


          (PROTOCOL= IPC)

          (KEY= ORCL)

        )
        (ADDRESS=


          (PROTOCOL= TCP)

          (Host= ff1)

          (Port= 1521)

        )
        (ADDRESS=


          (PROTOCOL= TCP)

          (Host= ff1)

          (Port= 1526)

        )
        (ADDRESS=


          (PROTOCOL= SPX)

          (Service= inventory_lsnr)

        )
        (ADDRESS=


          (PROTOCOL= NMP)

          (SERVER= nt_inventory_box)

          (PIPE= ORAPIPE)

        )

  )
STARTUP_WAIT_TIME_LISTENER = 0
CONNECT_TIMEOUT_LISTENER = 10 SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =

      (GLOBAL_DBNAME = ff1)
      (SID_NAME = ORCL)

    )
    (SID_DESC =

      (SID_NAME = extproc)
      (PROGRAM=extproc)
      (ORACLE_HOME=$ORACLE_HOME)

    )
  )

LOG_DIRECTORY_LISTENER = c:\orant\net80\trace TRACE_DIRECTORY_LISTENER = c:\orant\net80\trace TRACE_LEVEL_LISTENER = admin

The plsql test code is :

drop library zPrintString;
create library zPrintString as 'c:/newsys/bin/PrintString.dll';

select * from user_libraries;

create or replace procedure PrintString

		(OutPutString IN VARCHAR2)
		as external 
		Library zPrintString 
		name "zPrintString" 
		parameters (OutPutString STRING);

begin 
	execute PrintString('testing');

end;

Oracle tells me, that it is not able, to loead the dll. Error message is :

ORA-06520: PL/SQL: Error loading external library
ORA-06522: Unable to load DLL
