OTL连接Oracle-连接方式

otl_connect::otl_initialize(true);	//OTL连接数据库设置

try
{
string strConn = "";
//strConn = "ordsys/annet@orcltest207a";			//需要在TNS中配好IP和端口
strConn = "ordsys/annet@120.25.148.207:1521/orcltest207a";			//可以不依赖TNS
//strConn = "driver={Oracle}; server=(120.25.148.207);database=orcltest207a;uid=ordsys;pwd=annet";//没成功

db.rlogon(strConn.c_str()); // 连接到本地Oracle    账号/密码@数据库名
}
