linux发行版：centos5.5 x86_64
oracle版本：10g
问题：为什么zxm用户下无法连接数据库，而oracle用户下可以连接数据库？（zxm用户群组和oracle用户群组相同）
一个连接数据库的小程序：
[code=C/C++][/code]
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <sqlca.h>
EXEC SQL BEGIN DECLARE SECTION;
char username[10];
char password[10];
EXEC SQL END DECLARE SECTION;
int main()
{
strncpy(username,"bswdb",6);
strncpy(password,"bswdb",6);
EXEC SQL CONNECT :username IDENTIFIED BY :password;
if(0==sqlca.sqlcode){
printf("success!!\n");
printf("username:%s\npasswoad:%s\n",username,password);
}
else{
printf("返回错误：%d\n",sqlca.sqlcode);
printf("username:%s\npasswoad:%s\n",username,password);
}
return 0;
}

在zxm用户下执行结果：
[zxm@localhost test]$ test_oracle
返回错误：-1034
username:bswdb
passwoad:bswdb：
在oracle用户下执行结果：
[oracle:/home/oracle/test]$./test_oracle
success!!
username:bswdb
passwoad:bswdb

[color=#FF0000]以下是环境配置：[/color]
用户群组权限zxm用户和oracle用户是相同的：

[zxm@localhost ~]$ id
