# 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
5.
配置oracle网络服务的listener,配置文件是:listener.ora
默认路径:ORACLE_HOME etworkadmin
加入如下
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME= gateway_sid)
(ORACLE_HOME= oracle_home_directory)
(PROGRAM=tg4sybs)
)
)
gateway_sid就是3选择的sid字符串
(本文来源于图老师网站,更多请访问http://m.tulaoshi.com/wangguan/)oracle_home_directory是ORACLE_HOME
tg4sybs若是SYBASE是特定的。如果是其他数据库,会不同。
例子如下:
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
(SID_DESC=
(SID_NAME=tg4sybs)
(ORACLE_HOME = D:oracleora92)
(PROGRAM=tg4sybs)
)
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
6.
停止监听
lsnrctl stop
重新启动监听程序
lsnrctl start
7.
配置oracle server的tnsnames.ora使其能够访问sybase
connect_descriptor=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST= host_name)
(PORT= port_number)
)
(CONNECT_DATA=
(SID= gateway_sid))
(HS=OK))
connect_descriptor是连接串,任取,一般为sybs
host_name:oracle server的name
port_number:oracle监听端口
gateway_sid就是3选择的sid字符串
(本文来源于图老师网站,更多请访问http://m.tulaoshi.com/wangguan/)例子如下:
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
sybs=
(DESCRIPTION=
(ADDRESS_LIST =
(ADDRESS=(PROTOCOL=TCP)(HOST= dw-server1)(PORT= 1521))
)
(CONNECT_DATA=
(SID= tg4sybs)
)
(HS=OK)
)
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
8.建立database link
如:
CREATE DATABASE LINK sybs CONNECT TO sa
IDENTIFIED BY prient
USING "SBYS" ;
即可访问sybase 数据库。
需要注意的是,sybase数据库的表名,字段名,如果是小写的,那么在oracle里访问的时候要加上双引号""
如:
SQL〉select "a" from "b"@sybs;
