oracle查询dblink信息,oracle通过dblink查询sqlserver报错

报错如下：

SQL> select * from t@mstest;

select * from t@test

*

ERROR at line 1:

ORA-28545: error diagnosed by Net8 when connecting to an agent

Unable to retrieve text of NETWORK/NCR message 65535

ORA-02063: preceding 2 lines from MSSQL

解决办法：

说明：sqlserver版本为2008

gateway版本为11.2.0.4。

sqlserver端的listener中将program的值写成了tg4msql。11g版本应该为dg4msql，10g版本中为tg4msql

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = C:\product\11.2.0\tg_1)

(PROGRAM = extproc)

)

(SID_DESC =

(SID_NAME = test)

(ORACLE_HOME = C:\product\11.2.0\tg_1)

(PROGRAM = dg4msql)

)

)

再次执行成功
