Oracle 配置transparent gateway连接sqlserver数据库(gateway安装在oracle服务器上)

因业务需求，需要配置oracle访问sqlserver数据，故配置gateway
oracle服务器： 192.168.6.10
sqlserver服务器： 192.168.6.16

一、Oracle数据库服务器配置
1、Oracle 数据库服务器信息

[oracle@db ~]$ uname -a
Linux db 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 10 22:19:54 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
[oracle@db ~]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.6.10 db

SQL> select name,dbid,created from v$database;

NAME DBID CREATED
--------- ---------- ---------
ORCL 1435632369 30-MAR-16

SQL> select * from v$version;
BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
PL/SQL Release 11.2.0.4.0 - Production
CORE 11.2.0.4.0 Production
TNS for Linux: Version 11.2.0.4.0 - Production
NLSRTL Version 11.2.0.4.0 - Production

2、在Oracle服务器上安装gateway（11gR2 gateway是单独的安装包：11.2.0.4.0 x64是第五个安装包）
安装过程默认选择$ORACLE_HOME，安装后在ORACLE_HOME下生成 dg4msql目录
[oracle@db ~]$ cd $ORACLE_HOME
[oracle@db db_1]$ ls
apex clone cv demo has j2ee ldap network opmn owm racg sqldeveloper timingframework xdk
assistants config db_orcl dg4msql hs javavm lib nls oracore patch rdbms sqlj ucp
bin crs db_orcl1 diagnostics ide jdbc log oc4j oraInst.loc perl relnotes sqlplus uix
ccr csmig dbs dv install jdev md odbc ord plsql root.sh srvm usm
cdata css dc_ocm emcli instantclient jdk mesg olap oui precomp scheduler suptools utl
cfgtoollogs ctx deinstall EMStage inventory jlib mgw OPatch owb psu slax sysman wwg

3、在安装界面配置sqlserver数据库相关信息，记录于文件initdg4msql.ora中
[oracle@db db_1]$ cd dg4msql/
[oracle@db dg4msql]$ ls
admin demo driver lib log
[oracle@db dg4msql]$ cd admin/
[oracle@db admin]$ ls
dg4msql_cvw.sql dg4msql_tx.sql initdg4msql.ora listener.ora.sample tnsnames.ora.sample
注意：默认的ora文件名字为initdg4msql.ora，可无需修改直接使用。
[oracle@db admin]$ cat initdg4msql.ora
# 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
#本实验环境中sqlserver服务器为192.168.6.16，sqlserver端口为1433，sqlserver中的数据库为orcl
HS_FDS_CONNECT_INFO=[192.168.6.16]:1433//orcl
# alternate connect format is hostname/serverinstance/databasename
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER

4、修改$ORACLE_HOME/network/admin下的tnsnames.ora和listener.ora，添加sqlserver实例信息

[oracle@db admin]$ pwd
/u01/app/oracle/product/11.2.0/db_1/dg4msql/admin
[oracle@db admin]$ cd ../..
[oracle@db db_1]$ pwd
/u01/app/oracle/product/11.2.0/db_1
[oracle@db db_1]$ cd network/admin/
[oracle@db admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = dg4msql) --此处SID_NAME切勿修改，务必与 initdg4msql.ora中名字保持一致
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(PROGRAM = dg4msql) --此处为固定的，切勿修改
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = db)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
ADR_BASE_LISTENER = /u01/app/oracle

[oracle@db admin]$ cat tnsnames.ora
#tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = db)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
dg4msql =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.10)(PORT = 1521))
)
(CONNECT_DATA =
(SID = dg4msql)
)
(HS=OK) #此处表示连接的非oracle数据库
)

[oracle@db admin]$ tnsping dg4msql
TNS Ping Utility for Linux: Version 11.2.0.4.0 - Production on 27-APR-2016 16:04:58

OK (10 msec)

5、在Oracle数据库服务器上创建db_link

create database link tg4msql connect to sa identified by sa
using '(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.10)(PORT = 1521))
)
(CONNECT_DATA =
(SID = dg4msql)
)
(HS = OK)
)';

二、sqlserver数据库服务器配置信息



C:\Users\Administrator>hostname

WIN-MIRBE4NEBAU

C:\Users\Administrator>ipconfig

Windows IP 配置

以太网适配器 本地连接:

连接特定的 DNS 后缀 . . . . . . . :

本地链接 IPv6 地址. . . . . . . . : fe80::b993:1b16:9593:34d2%11

IPv4 地址 . . . . . . . . . . . . : 192.168.6.16

子网掩码 . . . . . . . . . . . . : 255.255.255.0

默认网关. . . . . . . . . . . . . : 192.168.6.1





确认sqlserver 1433端口已开通：



如上显示表明已开通。

三：在oracle数据库上测试查看sqlserver orcl数据库的shenfen表





说明:（以下部分待验证）
如果gateway没有安装在$ORACLE_HOME下，而是安装在/u01/app/oracle/product/11.2.0/tg_1（$GATEWAY_HOME）下的话，需要使用$GATEWAY_HOME下的listener.log和tnsnames.ora。（具体待验证）
需先停止原Oracle数据库的监听OracleOraDb11g_home1TNSListener，再启动透明网关的OracleOraTg11g_home1TNSListener监听服务。（注：在安装透明网关后，系统服务里会多出一下名叫：OracleOraTg11g_home1TNSListener的监听服务，注意和原监听服务OracleOraDb11g_home1TNSListener的区别，这也是为什么前面要求在设置环境变更Path的时候要保证GATEWAY_HOME必须在原DB的前面。）
