大家好，欢迎来到IT知识分享网。

OGG12C安装与配置

ogg12.2.0.1 仍旧可以支持oracle 11.2.0.4，但是需要打补丁17030189，且舍弃了一些参数。针对oracle11.2版本，个人建议还是用早期版本

 

注意点：保证捕获开始点和初始化数据加载点 数据的一致。

实验一概述

此实验以配置Integrated extract和Integrated replicate方式进行配置

环境：

         ogg版本：121210_fbo_ggs_Linux_x64_shiphome.zip

         oracle版本：11.2.0.4

         操作系统：RHEL6.5×64

2台服务器安装好数据库软件及实例，实例名可以不一样。此实验使用相同的ORACLE_SID

环境变量: vim ~oracle/.bash_profile

#export ORACLE_OWNER=oracle

#export ORACLE_TERM=xterm

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=/u01/app/oracle/product/11.2.0.4/dbhome_1

export ORACLE_SID=zytk

export LANG=en_US

export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK

export PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=/u01/app/oracle/ogg:$OR:$ORACLE_HOME/lib:/lib:/usr/lib

export EDITOR=/usr/bin/vim

export NLS_DATE_FORMAT=’yyyy-mm-dd hh24:mi:ss’

 

trail文件最好单独磁盘，以使得对系统影响最小。trail磁盘大小=每小时日志量*trailfile保存时间*0.4

完整捕获及重演模式消耗的是SGA中的内存，需要配置

1、安装OGG软件（源端、目标端）

此实验OGG软件安装在oracle用户下。

解压软件，运行runInstall.sh脚本。相比较之前版本，省略了create subdirs,且mgr可在安装过程中配置。

 

 

 

 

software location:修改为OGG的安装路径

2、建立OGG用户，并赋权限（源端和目标端）

[oracle@ogg1 ogg]$ sqlplus / as sysdba

SQL> create tablespace tbs_ogg datafile ‘/OracleData/zytk/tbs_ogg01.dbf’ size 10M autoextend on next 10M;

SQL> create user ogg identified by ogg default tablespace tbs_ogg;

SQL> grant dba to ogg;

 

3、数据库配置，打开辅助日志（源端和目标端）

[oracle@ogg1 ogg]$ sqlplus / as sysdba

SQL> alter database force logging;

SQL> alter database add supplemental log data;

 

SQL> select log_mode,supplemental_log_data_min,force_logging from v$database;

LOG_MODE         SUPPLEMENTAL_LOG FORCE_

———————— —————- ——

ARCHIVELOG                YES                YES

 

SQL> alter system set  enable_goldengate_replication=true scope=both; —（源端即可）

SQL> alter system switch logfile;

 

SQL> EXEC DBMS_GOLDENGATE_AUTH.GRANT_ADMIN_PRIVILEGE(‘ogg’);

 

alter system set UNDO_RETENTION=86400;  —-非必须，但有利于数据捕获应用

4、OGG源端配置

可选：一般出于安全考虑建议使用别名登录

创建登录别名,创建后可以用【dblogin useridalias 别名】进行登录

[oracle@ogg1 ogg]$ ./ggsci

GGSCI (ogg1.localdomain) 2>  add credentialstore

GGSCI (ogg1.localdomain) 3>  alter credentialstore add user ogg alias oggalias

 

4.1 GLOBALS全局配置

此实验未用到

 

4.2 MANAGER进程配置

[oracle@ogg1 ~]$ cd $GG_HOME

[oracle@ogg1 ogg]$ ./ggsci

GGSCI (ogg1.localdomain) 2> stop mgr !

GGSCI (ogg1.localdomain) 4> edit params mgr

PORT 7809

DYNAMICPORTLIST 7840-7914

AUTOSTART ER *

AUTORESTART ER *, RETRIES 3, WAITMINUTES 5, RESETMINUTES 60

–USERIDALIAS oggalias

USERID ogg, PASSWORD ogg

PURGEOLDEXTRACTS  /u01/app/oracle/ogg/dirdat/*, USECHECKPOINTS, MINKEEPDAYS 7

LAGREPORTHOURS 1

LAGINFOMINUTES 3

LAGCRITICALMINUTES 5

 

MANAGER进程参数配置说明：

PORT：指定服务监听端口；默认端口为7809

DYNAMICPORTLIST：动态端口：可以制定最大256个可用端口的动态列表，当指定的端口不可用时，管理进程将会从列表中选择一个可用的端口，源端和目标段的Collector、Replicat、GGSCI进程通信也会使用这些端口；

COMMENT：注释行，也可以用–来代替;

AUTOSTART：指定在管理进程启动时自动启动哪些进程；

AUTORESTART：自动重启参数设置：本处设置表示每3分钟尝试重新启动所有EXTRACT进程，共尝试5次；

PURGEOLDEXTRACTS：定期清理trail文件设置：本处设置表示对于超过3天的trail文件进行删除。

LAGREPORT、LAGINFO、LAGCRITICAL：

定义数据延迟的预警机制：本处设置表示MGR进程每隔1小时检查EXTRACT的延迟情况，如果超过了30分钟就把延迟作为信息记录到错误日志中，如果延迟超过了45分钟，则把它作为警告写到错误日志中。

USERIDALIAS:需要使用ADD CREDENTIALSTORE

           ALTER CREDENTIALSTORE ADD USER ogg ALIAS oggalias

 

4.3 EXTRACT进程配置

此处实验以INTEGRATED EXTRACT方式，而非经典模式。

该模式需要配置数据库streams_pool_size的值

 

GGSCI (ogg1.localdomain) 9> edit params ext1

EXTRACT ext1

dynamicresolution

–SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)

–SETENV (ORACLE_HOME = ‘/u01/app/oracle/product/11.2.0.4/dbhome_1’)

–SETENV (ORACLE_SID = ‘zytk’)

USERID ogg, PASSWORD ogg

TRANLOGOPTIONS INTEGRATEDPARAMS (MAX_SGA_SIZE 164)

LOGALLSUPCOLS

UPDATERECORDFORMAT COMPACT

EXTTRAIL ./dirdat/lt

TABLE zytk.*;

 

TRANLOGOPTIONS INTEGRATEDPARAMS (max_sga_size 300, _LOGMINER_READ_BUFFERS 128, parallelism 2)   —也可以设置并行度

 

GGSCI (ogg1.localdomain) 13> dblogin userid ogg, password ogg

Successfully logged into database.

GGSCI (ogg1.localdomain as ogg@zytk) 14> register extract ext1 database

Extract EXT1 successfully registered with database at SCN 1017765

GGSCI (ogg1.localdomain as ogg@zytk) 15> ADD EXTRACT ext1, INTEGRATED TRANLOG,BEGIN now

GGSCI (ogg1.localdomain as ogg@zytk) 16> ADD EXTTRAIL ./dirdat/lt, EXTRACT ext1

 

参数说明：

4.4 DATAPUMP进程配置

GGSCI (ogg1.localdomain as ogg@zytk) 19> edit params extdp1

EXTRACT extdp1

USERID ogg, PASSWORD ogg

RMTHOST ogg2.localdomain, MGRPORT 7809, KEYNAME securekey2

RMTTRAIL /u01/app/oracle/ogg/dirdat/rt

—- PASSTHRU 

TABLE zytk.*;

 

PASSTHRU  —如果源和目标端数据定义一致，则添加该参数

 

GGSCI (ogg1.localdomain as ogg@zytk) 22>  ADD EXTRACT extdp1, EXTTRAILSOURCE /u01/app/oracle/ogg/dirdat/lt, BEGIN now

GGSCI (ogg1.localdomain as ogg@zytk) 23> ADD RMTTRAIL /u01/app/oracle/ogg/dirdat/rt, EXTRACT extdp1

4.5 启动进程

—-mgr启动后，由于配置了autostart参数，其他extract进程也会随之启动，如果未启动查原因

GGSCI (ogg1.localdomain as ogg@zytk) 92> start mgr

 

5、OGG目标端配置

5.1 GLOBALS配置

5.2 MANAGER进程配置

 

5.3 REPLICAT进程配置

Integrated Replicat Mode

GGSCI (ogg2.localdomain) 3> edit params ./GLOBALS

CHECKPOINTTABLE ogg.checkpoint

GGSCI (ogg2.localdomain) 3> exit

[oracle@ogg2 ogg]$ ./ggsci

GGSCI (ogg2.localdomain as ogg@zytk) 1> dblogin userid ogg, password ogg

GGSCI (ogg2.localdomain as ogg@zytk) 2> add checkpointtable ogg.checkpoint

 

GGSCI (ogg2.localdomain) 10> edit params rep1

REPLICAT rep1

DBOPTIONS INTEGRATEDPARAMS(parallelism 2)

dynamicresolution

USERID ogg, PASSWORD ogg

ASSUMETARGETDEFS

MAP zytk.*, TARGET zytk.*;

 

GGSCI (ogg2.localdomain) 13> add replicat rep1 integrated exttrail ./dirdat/rt , checkpointtable ogg.checkpoint

REPLICAT (Integrated) added

 

暂时别启动进程

6、加载原始数据到目标端

此可以通过数据库本身的expdp、rman备份还原方式来完成，也可以通过ogg的初始数据加载方法进行，此实验用expdp方法实现。

SQL>  select current_scn from v$database;

CURRENT_SCN

———–

    1041649

[oracle@ogg1 ~]$ expdp zytk/zytk directory=dmp dumpfile=zytk01.dmp schemas=zytk flashback_scn=1041649

把导出的文件拷贝到目标端，进行还原

[oracle@ogg2 ~]$ impdp zytk/zytk directory=dmp dumpfile=zytk01.dmp schemas=zytk

—-table_exists_action=truncate

7、启动目标端进程

启动目标端进程，并测试

GGSCI (ogg2.localdomain) 10> start replicat rep1,aftercsn  1041649

 

至此:12c单向复制已经完成

 

实验二 配置DDL、SEQUENCE支持

在实验基础上，先停止所有进程，注意停止进程时判断下进程是否完成。

由于使用的是Integrated extract和Integrated replicat模式，不使用基于触发器的DDL捕获。

 

1 基于NATIVE 的DDL配置

1.1 源端

GGSCI (ogg1.localdomain) 3> edit params ext1

 

EXTRACT ext1

dynamicresolution

–SETENV (NLS_LANG=AMERICAN_AMERICA.ZHS16GBK)

–SETENV (ORACLE_HOME = ‘/u01/app/oracle/product/11.2.0.4/dbhome_1’)

–SETENV (ORACLE_SID = ‘zytk’)

USERID ogg, PASSWORD ogg

TRANLOGOPTIONS INTEGRATEDPARAMS (MAX_SGA_SIZE 164)

DDL INCLUDE ALL, EXCLUDE OBJNAME ogg.*

LOGALLSUPCOLS

UPDATERECORDFORMAT COMPACT

EXTTRAIL ./dirdat/lt

TABLE zytk.*;

 

1.2 目标端

GGSCI (ogg2.localdomain) 1> edit params rep1

REPLICAT rep1

DBOPTIONS INTEGRATEDPARAMS(parallelism 2)

dynamicresolution

ASSUMETARGETDEFS

DDL INCLUDE ALL, EXCLUDE OBJNAME ogg.*

MAP zytk.*, TARGET zytk.*;

                         

DDLOPTIONS MAPSESSIONSCHEMA SRC1 TARGET DST1  —如果一致可省略

2 基于触发器的DDL配置

一般用于经典模式的EXTRACT和REPLICAT模式

2.1 数据库配置

[oracle@ogg1 ~]$ cd $GG_HOME

[oracle@ogg1 ogg]$ sqlpluls / as sysdba

SQL> @marker_setup.sql;    —-输入OGG用户，此为ogg

SQL> @ddl_setup.sql;        —-输入OGG用户

SQL> @role_setup.sql;       —-输入OGG用户

SQL> GRANT GGS_GGSUSER_ROLE TO ogg;

SQL> @ddl_enable.sql;

SQL> @?/rdbms/admin/dbmspool.sql;   —-优化，可选

SQL> @ddl_pin ogg;

 

2.2 源端

[oracle@ogg1 ogg]$ ./ggsci

GGSCI (ogg1.localdomain) 1> edit params ./GLOBALS

GGSCHEMA ogg

—replicat需要检查表

—CHECKPOINTTABLE ogg.chkpoint

 

EXTRACT参数：

DDL INCLUDE OBJNAME SRC.* INCLUDE OBJNAME SRC1.*

GETTRUNCATES

 

2.3目标端

REPLICAT参数：

DDLOPTIONS MAPSESSIONSCHEMA SRC TARGET DST

 

 

实验三 配置双活模式

基于实验二基础上完成

先关闭OGG所有进程，然后进程相关配置修改。

1、源端

新增REPLICAT进程,修改原EXTRACT进程

1.1 新增REPLICAT进程

GGSCI (ogg1.localdomain) 3> edit params ./GLOBALS

GGSCI (ogg1.localdomain as ogg@zytk) 2> add checkpointtable ogg.checkpoint

 

GGSCI (ogg1.localdomain) 10> edit params rep2
