一、环境
公司网站系统使用的是IIS + Oracle
但公司某系统使用的是Sqlserver 2000, 但其数据需要做成报表放到网站上，为简化编程，使用Oracle做透明网关，定期从Sqlserver 抓取数据的方式
A: Web Server
- OS: Windows Server 2008
- IP: 10.108.3.10
- 安装软体：IIS, Oracle Client
B: Oralce DB Server
- OS: Windows Server 2008
- IP: 10.108.3.20
- 安装软体： Oracle DB, Oracle Gateway
C: Sqlserver 2000 DB Server
- OS: Windows Server 2003
- IP: 10.108.5.100
- 安装软体: Sqlserver 2000
这里面A和C的安装配置都很简单，主要说下B机器 Oracle透明网关的配置
二、Oracle透明网关配置
1. gateway安装
当然是要先安装好我们的Oracle DB,做好其它业务。然后再来安装Gateway
2. 配置 E:\Oracle\product\11.2.0\tg_1\dg4msql\admin\initdg4msql.ora
[
10.108.5.100].MSSQLSERVER.SQLDB HS_FDS_TRACE_LEVEL=OFF HS_FDS_RECOVERY_ACCOUNT=RECOVER HS_FDS_RECOVERY_PWD=RECOVER
Oracle Gateway在此文件中默认将sqlserver 2000的IP，实例名，数据库名以 / 分隔，这种设置后续会报错，改为以 . 分隔则OK
#HS_FDS_CONNECT_INFO=[10.108.5.100]/MSSQLSERVER/SQLDB
3. 配置E:\Oracle\product\11.2.0\tg_1\NETWORK\ADMIN\listener.ora
dg4msql =
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.108.3.20)(PORT = 1522)) ) (CONNECT_DATA = (SERVICE_NAME = dg4msql) ) (HS = OK) )
5. 配置E:\Oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
dg4msql = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.108.3.20)(PORT = 1522)) ) (CONNECT_DATA = (SERVICE_NAME = dg4msql) ) (HS = OK) ) ORACLR_CONNECTION_DATA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) ) (CONNECT_DATA = (SID = CLRExtProc) (PRESENTATION = RO) ) )
7. 建立DB link
-- Create database link create database link SQLSERVERLINK connect to sa identified by password using 'dg4msql';
