连接错误：ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA

wxcnl1 2012-05-10 05:45:07

我用ado.net去连接oracle出错
ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA

代码如下
this.connect = new OracleConnection("Data Source=computerName;User Id=system;Password=123456789;");
this.connect.Open();

我的tnsnames.ora如下

ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = computerName)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

我再其他客户端使用tnsping computerName都是没有问题的，太奇怪了
谢谢！

之前我用jdbc连接11g 碰到这样的问题。 11g不能用sid 用server_name 加反斜扛
