Oracle Gateway + Microsoft SQL Server
Adamhuan发表于 2017-05-24 07:47:18
开始本文的前提是：
1. 有一个MS Windows的服务器
2. 该服务器上安装了MS SQL Server
从甲骨文的官方网站获取GATEWAY在MS Windows下的安装介质：
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win64soft-094461.html
安装过程是图形化的，一步步的下一步就好：
配置参数：
参数文件位于：
MS SQL Server：C:\product\11.2.0\tg_1\dg4msql\admin\initdg4msql.ora
样例文件：C:\product\11.2.0\tg_1\inventory\Templates\dg4msql\admin\initdg4msql.ora
由于安装过程中有着一块的设置，所以，在我的环境里，这一文件的状态如下：
# This is a customized agent init file that contains the HS parameters # that are needed for the Database Gateway for Microsoft SQL Server # # HS init parameters # #HS_FDS_CONNECT_INFO=[192.168.92.170]/MSSQLSERVER/THEWORLD HS_FDS_CONNECT_INFO="192.168.92.170;DATABASE=THEWORLD" HS_FDS_TRACE_LEVEL=debug #HS_FDS_RECOVERY_ACCOUNT=sa #HS_FDS_RECOVERY_PWD=【SA的口令】 HS_FDS_RECOVERY_ACCOUNT=RECOVER HS_FDS_RECOVERY_PWD=RECOVER
修改监听器配置文件：
位于：C:\product\11.2.0\tg_1\NETWORK\ADMIN\listener.ora
修改为：
# listener.ora Network Configuration File: C:\product\11.2.0\tg_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
( SID_LIST =
( SID_DESC =
(SID_NAME=dg4msql)
(ORACLE_HOME=C:\product\11.2.0\tg_1)
(PROGRAM=dg4msql)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.92.170)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
ADR_BASE_LISTENER = C:\product\11.2.0\tg_1
重启或重新加载监听器：
PS C:\Users\Administrator> lsnrctl stop LSNRCTL for 64-bit Windows: Version 11.2.0.1.0 - Production on 24-5月 -2017 14:31:33 Copyright (c) 1991, 2010, Oracle.

然后，在另外一台装了Oracle的服务器上配置TNSNAMES，以便于可以访问上面配置的SQL Server：
[oracle@oracle-me database]$ cd $ORACLE_HOME/network/admin
[oracle@oracle-me admin]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/network/admin
[oracle@oracle-me admin]$
[oracle@oracle-me admin]$ ls
listener.ora samples shrept.lst sqlnet.ora tnsnames.ora
[oracle@oracle-me admin]$
[oracle@oracle-me admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
LENKA =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = oracle-me)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = lenka)
)
)
dg4msql =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.92.170)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = dg4msql)
)
(HS=OK)
)
[oracle@oracle-me admin]$
测试一下：
[oracle@oracle-me admin]$ tnsping dg4msql TNS Ping Utility for Linux: Version 11.2.0.4.0 - Production on 23-MAY-2017 23:58:59 Copyright (c) 1997, 2013, Oracle. All rights reserved.

然后，创建DBLINK，并查询一下：
[oracle@oracle-me admin]$ ps -ef | grep ora_
