源、执行-GoldenGate 单向DDL同步-by小雨

本篇文章笔者在北京喝咖啡的时候突然想到的...今天就有想写几篇关于源、执行-的文章，所以回家到之后就奋笔疾书的写出来发布了

       接着昨天的试验，这里用ogguser作为理管户用，用stat作为步同数据户用。

    
1. 源库和目标库ogguser户用都予赋dba角色和执行utl_file的权限：

     

       [oracle@dd1 ~]$ sqlplus / as sysdba
 
  SQL*Plus: Release 11.2.0.3.0 Production on Tue Apr 16 16:15:18 2013
 
  Copyright (c) 1982, 2011, Oracle.  All rights reserved.
 
 
  Connected to:
  Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
  With the Partitioning, OLAP, Data Mining and Real Application Testing options
 
  SQL> grant dba to ogguser;
 
  Grant succeeded.
 
  SQL> grant execute on utl_file to ogguser;
 
  Grant succeeded.

     

    2. 辑编源库全局参数件文
 
  [oracle@dd1 ogg11]$ cd $ORACLE_BASE/ogg11
  [oracle@dd1 ogg11]$ ggsci
 
  Oracle GoldenGate Command Interpreter for Oracle
  Version 11.1.1.1.2 OGGCORE_11.1.1.1.2_PLATFORMS_111004.2100
  Linux, x64, 64bit (optimized), Oracle 11g on Oct  4 2011 23:49:46
 
  Copyright (C) 1995, 2011, Oracle and/or its affiliates. All rights reserved.
 
 
  GGSCI (dd1) 1> edit param ./GLOBALS
 
  ggschema ogguser
 
3. 启用DDL持支设置（只要在源库设置）
 
  [oracle@dd1 ogg11]$ sqlplus / as sysdba
 
  SQL*Plus: Release 11.2.0.3.0 Production on Tue Apr 16 16:21:35 2013
 
  Copyright (c) 1982, 2011, Oracle.  All rights reserved.
 
 
  Connected to:
  Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
  With the Partitioning, OLAP, Data Mining and Real Application Testing options
 
  执行脚本marker_setup.sql：
  SQL> @marker_setup.sql
 
  Marker setup script
 
  You will be prompted for the name of a schema for the GoldenGate database objects.
  NOTE: The schema must be created prior to running this script.
  NOTE: Stop all DDL replication before starting this installation.

  option
 
 
  SQL> alter system set recyclebin=off scope=spfile; ##如果是10g，要需重启数据库，这里是11g，无需重启
 
  System altered.
 
  数据库开始强制日记：
  SQL> alter database force logging;
 
  Database altered.
 
  确认源库已处于归档模式，并启用附加日记和强制日记：
  SQL> select log_mode,supplemental_log_data_min,force_logging from v$database;
 
  LOG_MODE     SUPPLEME FOR
  ------------ -------- ---
  ARCHIVELOG   YES      YES
 
  执行脚本ddl_setup.sql：
  SQL> @ddl_setup.sql
 
  GoldenGate DDL Replication setup script
 
  Verifying that current user has privileges to install DDL Replication...
 
  You will be prompted for the name of a schema for the GoldenGate database objects.
  NOTE: For an Oracle 10g source, the system recycle bin must be disabled. For Oracle 11g and later, it can be enabled.
  NOTE: The schema must be created prior to running this script.
  NOTE: Stop all DDL replication before starting this installation.
 
  Enter GoldenGate schema name:ogguser ##入输ogguser
 
  You will be prompted for the mode of installation.
  To install or reinstall DDL replication, enter INITIALSETUP
  To upgrade DDL replication, enter NORMAL
  Enter mode of installation:INITIALSETUP
 
  Working, please wait ...

  执行脚本role_setup.sql：
  SQL> @role_setup.sql
 
  GGS Role setup script
 
  This script will drop and recreate the role GGS_GGSUSER_ROLE
  To use a different role name, quit this script and then edit the params.sql script to change the gg_role parameter to the preferred name. (Do not run the script.)
 
  You will be prompted for the name of a schema for the GoldenGate database objects.
  NOTE: The schema must be created prior to running this script.
  NOTE: Stop all DDL replication before starting this installation.
 
  Enter GoldenGate schema name:ogguser
  Wrote file role_setup_set.txt

  Grant this role to each user assigned to the Extract, GGSCI, and Manager processes, by using the following SQL command:
 
  GRANT GGS_GGSUSER_ROLE TO <loggedUser>
 
  where <loggedUser> is the user assigned to the GoldenGate processes.

4. 清除上一次试验环境

     

      源库：
  GGSCI (dd1) 38> delete extract einikk
 
  GGSCI (dd1) 38> delete extract eorakk
  2013-04-16 17:30:46  WARNING OGG-01753  Cannot unregister EXTRACT EORAKK from database because no database login was provided. You can manually unregister this group later with the UNREGISTER EXTRACT <GROUP NAME> LOGRETENTION command. Issue DBLOGIN first.
  Deleted EXTRACT EORAKK.
 
  GGSCI (dd1) 2> stop manager
  Manager process is required by other GGS processes.
  Are you sure you want to stop it (y/n)? y
 
  Sending STOP request to MANAGER ...
  Request processed.
  Manager stopped.
 
  目标库：
  GGSCI (kf2.calvin) 10> delete replicat rinikk
  Deleted REPLICAT RINIKK.
  GGSCI (kf2.calvin) 17> dblogin userid system ,password calvin
  Successfully logged into database.
 
  GGSCI (kf2.calvin) 18> delete CHECKPOINTTABLE SYSTEM.GGCHKPTABLE
  This checkpoint table may be required for other installations.  Are you sure you want to delete this checkpoint table? y
 
  Successfully deleted checkpoint table SYSTEM.GGCHKPTABLE.
 
  GGSCI (kf2.calvin) 19> delete replicat rorakk
  Deleted REPLICAT RORAKK.
 
  GGSCI (kf2.calvin) 1> stop manager
  Manager process is required by other GGS processes.
  Are you sure you want to stop it (y/n)? y
 
  Sending STOP request to MANAGER ...
  Request processed.
  Manager stopped.、

    
5. 源库和目标库建立测试户用，并授予权限

     

      SQL> create user stat identified by stat default tablespace testdata quota unlimited on testdata;
 
  User created.
 
  SQL> grant connect,resource,dba to stat;
 
  Grant succeeded.

     

    6. 对源库和目标库进行配置

     

      源库和目标库配置理管进程：
  GGSCI (dd1) 3> info all
 
  Program     Status      Group       Lag           Time Since Chkpt
 
  MANAGER     STOPPED
 
 
  GGSCI (dd1) 5> view params mgr
 
  -- this is configuration of this manager process
  PORT 7809
 
  GGSCI (dd1) 6> start manager
 
  Manager started.
 
 
  源库设置：
  GGSCI (dd1) 2> dblogin userid ogguser@test1,password ogguser
  Successfully logged into database.
 
  GGSCI (dd1) 3> add extract test1,tranlog,begin now  ##添加extract进程
  EXTRACT added.
 
 
  GGSCI (dd1) 4> add exttrail /data/oracle/ogg11/dirdat/lt,extract test1 ##添加extrail
  EXTTRAIL added.
 
  GGSCI (dd1) 5> edit params test1       ##辑编参数
  extract test1
  userid ogguser@test1, password ogguser
  rmthost 192.168.130.171, mgrport 7809
  rmttrail /data/oracle/ogg11/dirdat/lt
  ddl include mapped objname stat.*;
  table stat.*;
 
 
  GGSCI (dd1) 6> info all
 
  Program     Status      Group       Lag           Time Since Chkpt
 
  MANAGER     RUNNING                                          
  EXTRACT     STOPPED     TEST1       00:00:00      00:03:56
 
 
  目标库设置：
  GGSCI (kf2.calvin) 5> edit params ./GLOBALS  ##辑编全局参数件文
  GGSCHEMA ogguser
  CHECKPOINTTABLE ogguser.checkpoint
 
  GGSCI (kf2.calvin) 1> dblogin userid ogguser@test2,password ogguser
  Successfully logged into database.
 
  GGSCI (kf2.calvin) 3> add checkpointtable ogguser.checkpoint ##添加checkpoint表
 
  Successfully created checkpoint table OGGUSER.CHECKPOINT.
 
 
  GGSCI (kf2.calvin) 4> add replicat test2,exttrail /data/oracle/ogg11/dirdat/lt,checkpointtable ogguser.checkpoint ##添加replicat进程
  REPLICAT added.
 
 
  GGSCI (kf2.calvin) 5> edit params test2   ##设置参数
  replicat test2
  ASSUMETARGETDEFS
  userid ogguser@test2,password ogguser
  discardfile /data/oracle/ogg11/dirdat/test2_discard.txt,append, megabytes 10
  DDL INCLUDE MAPPED
  DDLERROR DEFAULT IGNORE RETRYOP
  map stat.*, target stat.*;
 
 
 
  源库开启extract进程，并检查info和report是否正常：
  GGSCI (dd1) 1> start extract test1
 
  Sending START request to MANAGER ...
  EXTRACT TEST1 starting
 
 
  GGSCI (dd1) 2> info all
 
  Program     Status      Group       Lag           Time Since Chkpt
 
  MANAGER     RUNNING                                          
  EXTRACT     RUNNING     TEST1       00:00:00      15:44:19
