【问题描述】：
我从 Oracle 尝试这个查询：
select * from "a_table"@Postgres;
这是我收到的错误消息：
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: précédant 2 lines de RECORD
28545. 0000 - "error diagnosed by Net8 when connecting to an agent"
*Cause: An attempt to call an external procedure or to issue SQL
to a non-Oracle system on a Heterogeneous Services database link
failed at connection initialization. The error diagnosed
by Net8 NCR software is reported separately.
*Action: Refer to the Net8 NCRO error message. If this isn't clear,
check connection administrative setup in tnsnames.ora
and listener.ora for the service associated with the
Heterogeneous Services database link being used, or with
'extproc_connection_data' for an external procedure call.
Erreur à la ligne 1, colonne 25
这里是 tnsnames.ora
Postgres =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(CONNECT_DATA =
(SID = RECORD)
)
(HS=OK)
)
这里是 listener.ora
LISTENER_HS =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1525))
(ADDRESS = (PROTOCOL = IPC)(KEY = PNPKEY))
)
)
)
SID_LIST_LISTENER_HS =
(SID_LIST =
(SID_DESC =
(SID_NAME = RECORD)
(ORACLE_HOME = /oracle/product/10.2.0)
(PROGRAM = hsodbc)
(ENVS = "LD_LIBRARY_PATH=/oracle/product/10.2.0/lib32:/oracle/product/10.2.0/hs/lib32:/user/lib")
)
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oracle/product/10.2.0)
(PROGRAM = extproc)
)
)
注意启动监听器后，这里是输出
$ lsnrctl status LISTENER_HS

编辑： 当我尝试手动检查 ODBC 驱动程序是否已启动并正在运行时，这就是我得到的：
$ isql postgres USER PASS -v
