ORACLE 9i连接SYBASE的透明网关的配置

ORACLE实现异种数据库连接服务的技术叫做透明网关（Transparent Gateway）。

目前ORACLE利用透明网关可以实现和SQL SERVER、SYBASE、DB2等多种主流数据库的互联。

现在通过oracle访问sybase数据库，把配置oracle9i TRANSPARENT GATEWAY FOR SYBASE的步骤写成文档，供需要的网友参考！

配置TRANSPARENT GATEWAY FOR SYBASE步骤

1.oracle所在服务器上安装sybase client（或者在同一台server上安装oracle、sybase服务器）确保能够访问sybase数据库

2.安装TRANSPARENT GATEWAY FOR SYBASE选件，要用自定义安装。正确选择sybase的安装目录

3.选择一个sid字符串准备赋给sybase数据库。如：tg4sybs设置SYBASE的dll路径到环境变量PATH（这一步很重要）

4.修改初始化文件，默认的是：

ORACLE_HOME\tg4sybs\admin\inittg4sybs.ora

设置参数

HS_FDS_CONNECT_INFO

格式：HS_FDS_CONNECT_INFO= server_name. database_name[,INTERFACE= interface_file]

server_name. database_name是大小写敏感的。

INTERFACE可选

例子：如下

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

# This is a sample agent init file that contains the HS parameters that are
# needed for the Transparent Gateway for Sybase
#
# HS init parameters
#
HS_FDS_CONNECT_INFO=migration_serv.tax
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
#
# Environment variables required for Sybase
#
set SYBASE=d:\sybase

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

上例中

server_name是migration_serv

database_name是tax
