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 SQL Server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SQL Server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。
