核心提示：1、安装oracle 的transparent gateway 透明网关，安装ORACLE 选择自定义安装，oracle透明网关环境的建立，然后再选择安装透明网关，再进去选择安装FOR SQLSERVER 的组件，2、修改 oraclehome\ora92\tgsmsql\admin\inittg4msql.or

1、安装oracle 的transparent gateway 透明网关。
安装ORACLE 选择自定义安装，然后再选择安装透明网关，再进去选择安装FOR SQLSERVER 的组件。
2、修改 oraclehome\ora92\tgsmsql\admin\inittg4msql.orq 文件

HS_FDS_CONNECT_INFO="SERVER=YIRONG-NO1;DATABASE=jsoct"
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
说明可以通过 ORACLE 工具中的migration WorkBench 进行配置。（过程中需要配置ODBC）

3、建立监听修改oracle 的 oraclehome\ora92\network\admin\listener.ora 文件。

# LISTENER.ORA Network Configuration File: F:\oracle\ora92\network\admin\listener.ora
# Generated by Oracle configuration tools.

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = yirong-no1)(PORT = 1521))
)

)
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = F:\oracle\ora92)
(PROGRAM = extproc)
)

(SID_DESC =
(GLOBAL_DBNAME = ora9i2)
(ORACLE_HOME = F:\oracle\ora92)
(SID_NAME = ora9i2)
)

#连接 sqlserver
(SID_DESC =
(GLOBAL_DBNAME = tg4msql)
(PROGRAM = tg4msql)
(SID_NAME = tg4msql)
(ORACLE_HOME = F:\oracle\ora92)
)

)

4、修改TNS

TG4MSQL =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))
(CONNECT_DATA=(SID=tg4msql))
(HS=)
)

5、创建DBLINK 说明建立的用户名，密码要是 SQLSERVER 的用户名和密码
create PUBLIC DATABASE LINK oratoSql
CONNECT TO sa IDENTIFIED BY "lanwei"
USING 'TG4MSQL' ;

6、测试数据的是否正常检索。
