oracle 透明网关环境的建立
兰伟 2007-0-082
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。
