第一步:需要去下载一个透明网管,相当于一个中间件(我们用的Oracle 11g,可能不同的数据库版本要安装不同的透明网管)#
需要的朋友请到我的百度云盘上下载

第二步:安装透明网关#
1、解压安装包后,点击setup.exe安装#
2、下一步(注:貌似一定要和Oracle数据库安装目录一致,第一次安装的时候,就和Oracle安装在不同地方了,最终百度很久发现,要和Oracle安装同一个位置)#
3、选择组建,选择SQL Server#
4、填写SQL SERVER的主机名和数据库名称#
5、开始安装#
6、安装完成后就退出,然后开始配置监听,下面是重点!!!!#
第三步:透明网关配置#
配置说明:#
本地Oracle安装目录:D:Oracleproduct11.2.0dbhome_1#
本地DBLink安装目录:D:Oracleproduct11.2.0dbhome_1#
SQL Server:账号:sa;密码:password;IP地址:127.0.0.1#
1、来到:D:Oracleproduct11.2.0dbhome_1dg4msqladmin;打开initdg4msql.ora
1 这个目录下可以看到以下initdg4msql.ora文件,上面在安装透明网关的时候有配置的要链接SQL SERVER数据的地址和数据库名称,在这里都可以体现:
配置文件:initdg4msql.ora#
1 # This is a customized agent init file that contains the HS parameters 2 # that are needed for the Database Gateway for Microsoft SQL Server 3 4 # 5 # HS init parameters 6 # 7 HS_FDS_CONNECT_INFO=[127.0.0.1]:1433//DEMO 注:连接其他的SQL Server可修改此处 8 HS_FDS_TRACE_LEVEL=OFF 9 HS_FDS_RECOVERY_ACCOUNT=RECOVER 10 HS_FDS_RECOVERY_PWD=RECOVER
检查一下HS_FDS_CONNECT_INFO是否是我们想要链接的地址,格式为:目标数据库的IP地址:端口//数据库名。SQL SERVER的默认端口是1433。#
配置文件:listener.ora.sample(localhost是监听的IP地址,这里我们连的是本地,127.0.0.1也是可以的)
1 # This is a sample listener.ora that contains the NET8 parameters that are 2 # needed to connect to an HS Agent 3 4 LISTENER = 5 (ADDRESS_LIST= 6 (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521)) 7 ) 8 9 SID_LIST_LISTENER= 10 (SID_LIST= 11 (SID_DESC= 12 (SID_NAME=dg4msql) 13 (ORACLE_HOME=D:Oracleproduct11.2.0dbhome_1) 14 (PROGRAM=dg4msql) 15 ) 16 ) 17 18 #CONNECT_TIMEOUT_LISTENER = 0
配置文件:tnsnames.ora.sample
1 # This is a sample tnsnames.ora that contains the NET8 parameters that are 2 # needed to connect to an HS Agent 3 4 dg4msql = 5 (DESCRIPTION= 6 (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521)) 7 (CONNECT_DATA=(SID=dg4msql)) 8 (HS=OK) 9 )
2、配置透明网关的监听,来到:D:Oracleproduct11.2.0dbhome_1NETWORKADMIN(开始配置这3个文件)
配置文件:listener.ora
1 # This is a sample listener.ora that contains the NET8 parameters that are 2 # needed to connect to an HS Agent 3 SID_LIST_LISTENER = 4 (SID_LIST = 5 (SID_DESC = 6 (SID_NAME = CLRExtProc) 7 (ORACLE_HOME = D:Oracleproduct11.2.0dbhome_1) 8 (PROGRAM = extproc) 9 (ENVS = "EXTPROC_DLLS=ONLY:D:Oracleproduct11.2.0dbhome_1inoraclr11.dll") 10 ) 11 (SID_DESC= 12 (SID_NAME=dg4msql) 13 (ORACLE_HOME=D:Oracleproduct11.2.0dbhome_1) 14 (PROGRAM=dg4msql) 15 ) 16 ) 17 18 LISTENER = 19 (DESCRIPTION_LIST = 20 (DESCRIPTION = 21 (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) 22 (ADDRESS = (PROTOCOL = TCP)(HOST = YRDLG5GS4G3ODYI)(PORT = 1521)) 23 (ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=1521)) 24 ) 25 ) 26 27 ADR_BASE_LISTENER = D:Oracle 28 29 #CONNECT_TIMEOUT_LISTENER = 0
1 这里需要注意的主要是一下几点: 2 PROGRAM为dg4msql:因为实例的配置文件在dg4msql目录下,就是上面的initdg4msql.ora文件所在的目录 3 SID_NAME为dg4msql:这个sid就是上面的文件名中的sid,initdg4msql.ora的sid为dg4msql 4 ORACLE_HOME就是我们透明网关的安装目录 5 ORACLE的监听端口是1521,我的oracle和透明网关是安装在同一台机器上的,所以透明网关的监听端口设置为1522。 6 一个initSID.ora文件就对应一个SID_DESC,可以根据想要链接的数据库来配置。
配置文件:sqlnet.ora
1 # sqlnet.ora Network Configuration File: D:Oracleproduct11.2.0dbhome_1 etworkadminsqlnet.ora 2 # Generated by Oracle configuration tools. 3 4 # This file is actually generated by netca. But if customers choose to 5 # install "Software Only", this file wont exist and without the native 6 # authentication, they will not be able to connect to the database on NT. 7 8 SQLNET.AUTHENTICATION_SERVICES= (NONE) 9 10 NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
配置文件:tnsnames.ora
1 # This is a sample tnsnames.ora that contains the NET8 parameters that are 2 # needed to connect to an HS Agent 3 ORCL = 4 (DESCRIPTION = 5 (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) 6 (CONNECT_DATA = 7 (SERVER = DEDICATED) 8 (SERVICE_NAME = orcl) 9 ) 10 ) 11 12 dg4msql = 13 (DESCRIPTION= 14 (ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=1521)) 15 (CONNECT_DATA=(SID=dg4msql)) 16 (HS=OK) 17 )
配置完之后,一定不要忘记重启监听!!!!!!一定不要忘记重启监听!!!!!!一定不要忘记重启监听!!!!!!
1 命令:lsnrctl reload
查看监听状态:
第四步:Oracle配置DBLink#
1、先查看哪些用户可以使用DBLink,没有则创建权限
1 SELECT * FROM user_sys_privs where privilege like upper('%DATABASE LINK%')
赋权限配置命令
1 如:grant create public database link to system ; 2 格式:grant create public database link to 用户名 ;
2、建立DBLink(用户要一定要权限才可以继续往下执行哦!没有的往上看,给用户配置权限)
1 查询dblink: 2 select * from dba_db_links; 3 4 删除dblink: 5 DROP DATABASE LINK [name];
1 create database link DBTEST1 2 connect to SA identified by "password" 3 using 'dg4msql'; 4 5 6 7 格式: 8 create database link DBLink名称 9 connect to SQL Server账户 identified by "SQL Server密码" 10 using 'SID';
搞定!!!!#
下面这个报错信息,QQ群问一个遍,很少人知道DBLink这玩意,百度上资料也很少,捣鼓一下午,终于搞定了
出现这个问题是因为这6个文件导致的!!!!!!
捣鼓一下午,问题找到是因为这6个文件配置出问题了,这次就不再叙述了,修改那个配置文件了,配置文件因人而异,剩下的自己百度去查吧~~~~好了,捣鼓一天了,洗洗睡了,拜~~
