Oracle GoldenGate学习之--基本概念和配置（3）
网站设计、成都网站设计的开发，更需要了解用户，从用户角度来建设网站，获得较好的用户体验。创新互联多年互联网经验，见的多，沟通容易、能帮助客户提出的运营建议。作为成都一家网络公司，打造的就是网站建设产品直销的概念。选择创新互联，不只是建站，我们把建站作为产品，不断的更新、完善，让每位来访用户感受到浩方产品的价值服务。
系统架构：
OGG基本配置（单向传输）
1、数据库配置（Source DB)
建立Tablespace： 11:58:56 SYS@ prod >create tablespace ogg_tbs 11:59:12 2 datafile '/u01/app/oracle/oradata/prod/oggtbs1.dbf' size 100m ; 建立ogg用户： 12:01:17 SYS@ prod >create user ogg identified by ogg default tablespace ogg_tbs temporary tablespace temp quota unlimited on ogg_tbs; User created. 用户授权： 12:01:39 SYS@ prod >grant connect,resource to ogg; Grant succeeded. 12:01:55 SYS@ prod >grant create session,alter session to ogg; Grant succeeded. 12:02:18 SYS@ prod >grant select any dictionary,select any table to ogg; Grant succeeded. 12:02:42 SYS@ prod >grant alter any table to ogg; Grant succeeded. 12:02:53 SYS@ prod >grant flashback any table to ogg; Grant succeeded. 12:03:03 SYS@ prod >grant execute on dbms_flashback to ogg; Grant succeeded. 在Database上启用附加日志功能： 12:19:26 SYS@ prod >select SUPPLEMENTAL_LOG_DATA_MIN from v$database; SUPPLEME -------- NO 12:20:53 SYS@ prod >alter database add supplemental log data; Database altered. 数据库应为归档模式： 12:21:10 SYS@ prod >archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination /dsk4/arch_prod Oldest online log sequence 78 Next log sequence to archive 80 Current log sequence 80 13:22:45 SYS@ prod >select force_logging from v$database; FOR --- NO 13:24:22 SYS@ prod >alter database force logging; Database altered. 13:24:30 SYS@ prod >select force_logging from v$database; FOR --- YES 建立用于传输测试的Table： 12:12:26 SCOTT@ prod >create table emp_ogg as select * from emp; Table created. 12:12:40 SCOTT@ prod >alter table emp_ogg add constraint pk_ogg primary key(empno); 注意：Oracle建议给所有要复制的表建立主键或唯一键
2、数据库配置（Target DB)
建立Tablespace： 12:07:50 SYS@ prod >create tablespace ogg_tbs 12:08:09 2 datafile '/u01/app/oracle/oradata/prod/oggtbs1.dbf' size 100m; 建立ogg用户： 12:08:47 SYS@ prod >create user ogg identified by ogg default tablespace ogg_tbs temporary tablespace temp quota unlimited on ogg_tbs; User created. 用户授权： 12:09:44 SYS@ prod >grant connect,resource to ogg; Grant succeeded. 12:10:06 SYS@ prod >grant create session ,alter session to ogg; Grant succeeded. 12:10:20 SYS@ prod >grant select any table,select any dictionary to ogg; Grant succeeded. 12:10:45 SYS@ prod >grant create table to ogg; 创建测试Table： 12:13:47 SCOTT@ prod >create table emp_ogg as select * from emp; Table created. 12:14:04 SCOTT@ prod >grant all on emp_ogg to ogg； Grant succeeded.
