oracle ogg 单实例单向简单搭建测试（oracle-oracle）

昨天突然接到消息说有一个线上的ogg出现了问题，看是否能修复，由于ogg以前玩的少，所以就加急搞了个测试环境，练习了一把

环境

db1,db2(单实例)
ip: 1*,1*
sid: orcl,ogg1
os: centos 6.5,centos 6.5
oracle version: 11.2.0.4,11.2.0.4

1 --可以创建ogg用户，也可以使用oracle用户

useradd -u 2100 -g oinstall -G dba ogg
passwd ogg

[ogg@DSI ~]$ vim .bash_profile
export LD_LIBRARY_PATH=/u01/app/oracle/product/11.2.0/db_1/lib
export ORACLE_SID=orcl
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/jdk/bin:$PATH
[ogg@DSI ~]$ source .bash_profile 

2 下载安装ogg

[root@DSI ~]# mkdir -p /u01/app/ogg 
[root@DSI ~]# chown -R oracle:oinstall /u01/app/ogg
[root@DSI opt]# unzip ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip 
Archive:  ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip
  inflating: fbo_ggs_Linux_x64_ora11g_64bit.tar  
  inflating: OGG_WinUnix_Rel_Notes_11.2.1.0.1.pdf  
  inflating: Oracle GoldenGate 11.2.1.0.1 README.txt  
  inflating: Oracle GoldenGate 11.2.1.0.1 README.doc 
[root@DSI opt]# tar -xvf fbo_ggs_Linux_x64_ora11g_64bit.tar -C /u01/app/ogg/
[root@DSI ogg]# chown -R oracle:oinstall /u01/app/ogg

解压成功之后，登录OGG测试

[oracle@DSI ogg]$ ./ggsci

##注意：如果LD_LIBRARY_PATH变量设置正确，会像上面演示一样正确进入命令行，如果提示找不到so文件，就需要查看LD_LIBRARY_PATH变量是否配置正确

3 源端创建OGG表空间和OGG用户---两个服务器都要做

SYS@ orcl > create tablespace ogg datafile '/u01/app/oracle/oradata/orcl/ogg01.dbf' size 50m autoextend on;
Tablespace created.
SYS@ orcl > create user ogg identified by ogg default tablespace ogg;
User created
SYS@ orcl >grant CONNECT, RESOURCE to ogg;
Grant succeeded.
SYS@ orcl >grant SELECT ANY DICTIONARY, SELECT ANY TABLE to ogg;
Grant succeeded.
SYS@ orcl >grant ALTER ANY TABLE to ogg;
Grant succeeded.
SYS@ orcl >grant FLASHBACK ANY TABLE to ogg;
Grant succeeded.
SYS@ orcl >grant EXECUTE on DBMS_FLASHBACK to ogg;
Grant succeeded.
SYS@ orcl >grant insert any table to ogg;
Grant succeeded.
SYS@ orcl >grant update any table to ogg;
Grant succeeded.
SYS@ orcl >grant delete any table to ogg;
Grant succeeded.
或者
grant resource,connect,dba to ogg;

打开数据库的附加日志和 force log
SYS@ orcl >select NAME,OPEN_MODE,FORCE_LOGGING,SUPPLEMENTAL_LOG_DATA_MIN from v$database;
NAME      OPEN_MODE           FOR SUPPLEME
--------- -------------------- --- --------
ORCL      READ WRITE           NO  YES
SYS@ orcl >alter database force logging;
Database altered.
SYS@ orcl >alter database add SUPPLEMENTAL log data;
Database altered.
SYS@ orcl >select NAME,OPEN_MODE,FORCE_LOGGING,SUPPLEMENTAL_LOG_DATA_MIN from v$database;
NAME      OPEN_MODE           FOR SUPPLEME
--------- -------------------- --- --------
ORCL      READ WRITE           YES YES
SYS@ orcl >alter system switch logfile;
---运行 OGG 支持 DDL 脚本
如果要让 OGG 支持 DDL 操作，还需要额外运行几个脚本，这些脚本是 OGG 带的而不是 ORACLE 带的，源端与目标端都需要
---SYS@ orcl >@/u01/app/ogg/marker_setup.sql
---SYS@ orcl >@/u01/app/ogg/ddl_setup.sql
---SYS@ orcl >@/u01/app/ogg/role_setup.sql
---SYS@ orcl >@/u01/app/ogg/ddl_enable.sql

ogg实例是刚搭建的新环境

alias ggsci="/u01/app/ogg/ggsci"

4 开始进行搭建

源 orcl
1 创建 OGG 的管理目录

GGSCI (DSI) 1> create subdirs
Creating subdirectories under current directory /u01/app/ogg

Parameter files                /u01/app/ogg/dirprm: already exists
Report files                   /u01/app/ogg/dirrpt: created

Stdout files                   /u01/app/ogg/dirout: created

2 建立测试表
SYS@ ogg >@/u01/app/oracle/product/11.2.0/db_1/rdbms/admin/utlsampl.sql
--实例orcl
SYS@ orcl> conn scott/*
Connected.
SCOTT@ orcl >create table emp_ogg as select * from emp;
Table created.
SCOTT@ orcl >create table dept_ogg as select * from dept;
Table created.
SCOTT@ orcl >alter table EMP_OGG add constraint PK_EMPNO_OGG primary key (EMPNO);
Table altered.
SCOTT@ orcl >alter table DEPT_OGG add constraint PK_DEPTNO_OGG primary key (DEPTNO);
Table altered.
--实例ogg
SYS@ ogg >conn scott/*
Connected.
SCOTT@ ogg > create table emp_ogg as select * from emp where 1=2;
Table created.
SCOTT@ ogg >create table dept_ogg as select * from dept where 1=2;
Table created.
SCOTT@ ogg >alter table EMP_OGG add constraint PK_EMPNO_OGG primary key (EMPNO);
Table altered.
SCOTT@ ogg >alter table DEPT_OGG add constraint PK_DEPTNO_OGG primary key (DEPTNO);
Table altered.

3 源端添加表级 TRANDATA

GGSCI (DSI) 2> DBLOGIN USERID ogg, PASSWORD ogg
Successfully logged into database.
GGSCI (DSI) 3> add trandata scott.emp_ogg
Logging of supplemental redo log data is already enabled for table SCOTT.EMP_OGG.
GGSCI (DSI) 4> add trandata scott.dept_ogg
Logging of supplemental redo log data is already enabled for table SCOTT.DEPT_OGG.
GGSCI (DSI) 5> INFO TRANDATA scott.*
Logging of supplemental redo log data is disabled for table SCOTT.BONUS.
Logging of supplemental redo log data is disabled for table SCOTT.DEPT.
Logging of supplemental redo log data is enabled for table SCOTT.DEPT_OGG.
Columns supplementally logged for table SCOTT.DEPT_OGG: DEPTNO.
Logging of supplemental redo log data is disabled for table SCOTT.EMP.
Logging of supplemental redo log data is enabled for table SCOTT.EMP_OGG.
Columns supplementally logged for table SCOTT.EMP_OGG: EMPNO.
Logging of supplemental redo log data is disabled for table SCOTT.SALGRADE.

4 配置 MGR 管理进程

GGSCI (DSI) 6> edit params mgr
PORT 7809
PURGEOLDEXTRACTS /u01/app/ogg/dirdat, USECHECKPOINTS
参数说明：
    PORT 7809： OGG 管理进程监控端口。
    PURGEOLDEXTRACTS：清除不需要的 trail 文件。
    /u01/app/ogg/dirdat： trail 文件存放位置。
    USECHECKPOINTS：使用检查点队列
GGSCI (DSI) 7> start mgr
Manager started.
GGSCI (DSI) 8> info mgr
Manager is running (IP port DSI.7809).

5 配置初始化数据进程

由于在创建测试表的时候，源端的测试表有数据，而目标端的测试表只有结构，没有数据，所以需要初始
化目标端的数据，所谓初始化，就是让目标端的数据和源端的数据在这个时间点是一模一样的， 所以初始化工
作并不需要一定使用 OGG，也可以使用 EXP、 EXPDP、 SQLLOAD 等其他工具
##使用 OGG 进行数据初始化， 下面在源端配置捕获进程 EINI_1

GGSCI (DSI) 9> ADD EXTRACT EINI_1, SOURCEISTABLE
EXTRACT added.
GGSCI (DSI) 10> INFO EXTRACT *, TASKS
EXTRACT    EINI_1    Initialized   2019-06-19 14:00   Status STOPPED
Checkpoint Lag       Not Available
Log Read Checkpoint  Not Available
                     First Record         Record 0
Task                 SOURCEISTABLE
GGSCI (DSI) 11> EDIT PARAMS EINI_1
EXTRACT EINI_1
SETENV (NLS_LANG=AMERICAN_AMERICA.AL32UTF8)
USERID ogg, PASSWORD ogg
RMTHOST 1*, MGRPORT 7809
RMTTASK REPLICAT, GROUP RINI_1
TABLE scott.EMP_OGG;
TABLE scott.DEPT_OGG;
参数介绍：
    EXTRACT EINI_1：说明这是 EXTRACT 进程，名字是 EINI_1
    SETENV：环境变量，一定要设置和数据库字符集一样，否则可能会乱码
    USERID：数据库 OGG 用户
    PASSWORD：数据库用户 OGG 的密码
    RMTHOST：目标端地址，如果在/etc/hosts 文件里已经设置解析，可以写主机名
    MGRPORT：目标端 MGR 管理进程监听的端口
    RMTTASK REPLICAT：目标端 REPLICAT 应用进程的组和名字
    TABLE：源端要初始化数据的表的名字

编辑好捕获进程 EINI_1 后， 还需要在目标端配置 REPLICAT 应用进程，名字要和源端的捕获进程 EINI_1 里面 RMTTASK REPLICAT 参数配置的一样，
也就是还需要在目标端配置 RMTTASK REPLICAT RINI_1

目 ogg
[oracle@ogg ~]$ alias ggsci="/u01/app/ogg/ggsci"
[oracle@ogg ~]$ ggsci
GGSCI (ogg) 1> create subdirs

Creating subdirectories under current directory /u01/app/ogg

Parameter files                /u01/app/ogg/dirprm: already exists
Report files                   /u01/app/ogg/dirrpt: created
Checkpoint files               /u01/app/ogg/dirchk: created
Process status files           /u01/app/ogg/dirpcs: created
SQL script files               /u01/app/ogg/dirsql: created

Extract data files             /u01/app/ogg/dirdat: created
Temporary files                /u01/app/ogg/dirtmp: created
Stdout files                   /u01/app/ogg/dirout: created
目标端
GGSCI (ogg) 2> edit params mgr
PORT 7809
PURGEOLDEXTRACTS /u01/app/ogg/dirdat, USECHECKPOINTS
GGSCI (ogg) 3> start mgr
Manager started.
GGSCI (ogg) 4> info mgr
Manager is running (IP port ogg.7809).

7 配置目标端 REPLICAT 进程

GGSCI (ogg) 5> EDIT PARAMS RINI_1
REPLICAT RINI_1
SETENV (NLS_LANG=AMERICAN_AMERICA.AL32UTF8)
ASSUMETARGETDEFS
USERID ogg, PASSWORD ogg
DISCARDFILE /u01/app/ogg/dirrpt/RINIaa.dsc, PURGE
MAP scott.*, TARGET scott.*;

参数介绍：
    REPLICAT RINI_1：说明这是 REPLICAT 应用进程，名字叫 RINI_1
    SETENV：语言变量，同捕获进程 EINI_1
    ASSUMETARGETDEFS：告诉 OGG 目标端和源端需要同步的表的结构完全一致，不需要 OGG 去检查表的结构，包括
    表名、字段名、字段类型、字段长度等，如果目标端和源端同步的表的结构不一样，需要使用 SOURCEDEFS 参
    数，详见 OGG 官方文档。
    USERID、 PASSWORD：同捕获进程 EINI_1 参数介绍
    DISCARDFILE： 错误信息存放位置及命名规则
    MAP：源端捕获的表的名字
    TARGET：目标端同步的表的名字，可以不在同一 SCHEMA。

8 初始化数据

配置好目标端的应用进程 RINI_1 后， 就可以启动源端的捕获进程进行捕获数据了，而目标端的应用进程 RINI_1 不需要手动去启动，也就是说目标端 RINI_1 进程不需要管

GGSCI (DSI) 12> START EXTRACT EINI_1

10 源端和目标端配置 OGG 的检查点

此步骤不是必须的，但是为了让 OGG 网络中断、服务器宕机、掉电等在突发情况也能正确断点续传， ORACLE 建议配置 OGG 的检查点队列。
源端和目标端都需配置

12 源端配置 PUMP 传输进程

##此步骤也是非必须的，如果不配置传输进程， OGG 会通过 EXTRACT 进程传输 TRAIL 队列文件，但是和检查点队列一样，为了保证断点续传 ORACLE 建议配置 PUMP 传输进程

至此 简单的单实例单向同步已经完成

注明：此文档跟网上有些文档类似，因为临时的原因，在我以前下载的资料里面找的pdf进行测试，发现是一个很早的pdf，找不到原文链接---

这里的实验测试完全真实有效~~

后面会测试：修改表的同步，新增表的同步，双向同步，以及切换等

其他mgr，等一些命令参数，官网或者网上有大部分的资料，这里不做列举，因为还没研究这些（~~~）
