Dynamic library+ Linux + ORACLE 10.2

Question

Hello !
I have Linux + ORACLE 10.2
$ env | grep LAN
NLS_LANG=AMERICAN_AMERICA.UTF8
LANG=en_US.UTF-8
database parameters:
1 NLS_LANGUAGE AMERICAN
2 NLS_TERRITORY AMERICA
3 NLS_CHARACTERSET UTF8
4 NLS_NCHAR_CHARACTERSET AL16UTF16
I have a dynamic library and plsql function:
#include <stdio.h>
int sysrun(char command, char ying, char *yang)
FILE *fpointer ;
fpointer = fopen("out6.txt","wt");
if (!fpointer)
printf( "!!! file error \n" );
return;
fprintf(fpointer,"ying:%s yang:%s command:%s \n",ying,yang,command);
fclose(fpointer);
return 0;
//return system(command);
create or replace function sysrun_2 (syscomm in varchar2, ying IN VARCHAR2, yang IN VARCHAR2 )
return binary_integer
as language C
name "sysrun"
library shell_lib
parameters(syscomm string, ying string,yang string);
I send to library russian words(by sqlplus), but it write in a file bad symbols
'п╡я▀'
I run query on sqlplus:
SELECT CONVERT('п╡я▀', VALUE) conv,VALUE FROM
v$nls_valid_values v
where parameter = 'CHARACTERSET';
And see, that the best code page is CL8KOI8R
why CL8KOI8R? And where's from ?
And how can I change it ?
P.S. when I call library from Linux it's ok !!

Answer 1

Hi,
I'm not familiar with Russian characters and charsets like CL8KOI8R. Have you tried creating a table in the database and inserting the same characters to verify if that works?
It might be worth verifying if the environment variables are correct for the extproc process as well. I'm not sure if the environment variables you listed are for the "oracle" user or not.
Also, are you using the Oracle C++ Call Interface (OCCI) with this?
