I have one C Dll that should be called in PL/SQL.
To achieve this, I have done the following steps but I am not successful.
Please go thru my solution, and suggest me how I can correct this problem.
Step 1:
Created shell.c
#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
void __declspec(dllexport) sh(char *);
void sh(char *cmd)
{
system(cmd);
}
Step 2:
Compiled with the following options:
bcc32 -WD shell.c
implib shell.lib shell.dll
bcc32 shell_run.c shell.lib
Step 3:
Created Oracle Library
CREATE OR REPLACE LIBRARY DEMOLIB IS 'd:oracleora92binshell.dll';
Step 4:
Created Shell Procedure with External Lib
create or replace procedure shell
(
cmd IN varchar2)
as external
NAME "_sh"
LIBRARY "DEMOLIB"
LANGUAGE C
PARAMETERS (cmd string);
/
Step 5:
Testing the Procedure
exec shell('del c:a.txt');
I am get the following error.
BEGIN shell('del c:a.txt'); END;
*
ERROR at line 1:
ORA-28595: Extproc agent : Invalid DLL Path
ORA-06512: at "CON_OWNER.SHELL", line 0
ORA-06512: at line 1
Please refer my TNSNAMES.ORA and LISTENER.ORA
