I am trying to call an External Function but Oracle says ORA-01041: internal error. hostdef extension doesn't exist .
How do I do it??
I have done all this (see example below)
/* In the MyFunc.dll (Borland C++ Builder) File Code the Following: */
#include
#include
#include
#include
extern "C" __declspec(dllexport) int TestFunc(int);
int TestFunc(int arg1)
{
return arg1*2;
}
/* In the tnsnames.ora File, added the Following Entry: */
extproc_connection_data =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(CONNECT_DATA = (SID = ORCL))
)
/* In the listener.ora File, added the Following Entries: */
EXTERNAL_PROCEDURE_LISTENER =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL=ipc)
(KEY= EXTPROC0)
)
)
SID_LIST_EXTERNAL_PROCEDURE_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = ORCL)
(ORACLE_HOME=/orant)
(PROGRAM=extproc)
)
)
CREATE OR REPLACE LIBRARY MyLib AS '/orant/mydir/MyFunc.dll';
CREATE OR REPLACE FUNCTION F_MyFunc (Arg1 IN BINARY_INTEGER)
RETURN BINARY_INTEGER AS
EXTERNAL LIBRARY MyLib
NAME "TestFunc"
LANGUAGE C
CALLING STANDARD C
PARAMETERS (Arg1 int, RETURN);
/
Function created.
VARIABLE MyVar NUMBER;
BEGIN
:MyVar := F_MyFunc (7);
END;
/
ERROR at line 1:
ORA-01041: internal error. hostdef extension doesn't exist
Did I miss something in the configuration?
Has anybody faced the similar problems and if yes, how were you able to overcome ?
