简介

由于业务系统要与大数据平台进行对接，需要将Oracle DB的数据同步到异构数据库上，故选用也不得不用上了Goldengate方案

然鹅，OGG在RAC上的HA配置一直众说纷纭，我搜索了下发现多数为single node的配置。几经探索，在这里将OGG在RAC的HA配置整理起来，为需要的伙伴提供一点思路

半部分数据已进行脱敏。

环境信息

源端数据库信息

HOSTNAME	IP	DB/schema
dbdc1	10.0.24.131 (scan:10.0.24.135\136\137)	CTCN/POS
dbdc2	10.0.24.132 (scan:10.0.24.135\136\137)	CTCN/POS

源端数据库版本：Oracle DB 12.1.0.1 RAC (SE)
OGG版本：OGG-12.2.0.1
计划的OGG VIP：10.0.24.138
目标端：OGG for bigdata
目标端地址：10.18.0.41

安装OGG

配置ACFS，mount到/u01/ogg

配置oracle用户环境变量

[root@dbdc1 ogg]#  ~oracle/.bash_profile 

新增

export OGG_HOME=/u01/ogg/gg

PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$OGG_HOME

export LD_LIBRARY_PATH=$ORACLE_HOME/lib

创建目录并设置权限

[root@dbdc1 ogg]# mdkir /u01/ogg/gg

[root@dbdc1 ogg]# chown -R oracle:oinstall /u01/ogg

下载OGG 12.2.0.1 安装包并上传

[root@dbdc1 ogg]# ls -lh /u01/software/V100692-01.zip

-rw-r--r-- 1 oracle oinstall 454M Sep  9 14:25 /u01/software/V100692-01.zip

解压

[root@dbdc1 software]# unzip V100692-01.zip -d ogg

使用oracle用户，通过X11安装

[oracle@dbdc1 Disk1]$ pwd

/u01/software/ogg/fbo_ggs_Linux_x64_shiphome/Disk1

[oracle@dbdc1 Disk1]$ ./runInstaller

指定安装位置为ACFS的挂载点/u01/ogg/gg
完成安装

配置数据库

开启数据库级别日志补充

[oracle@dbdc1 ~]$ export ORACLE_SID=CTCN1

[oracle@dbdc1 ~]$ sqlplus / as sysdba

SQL> ALTER DATABASE FORCE LOGGING;

Database altered.

SQL> ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;

Database altered.

SQL> ALTER SYSTEM ARCHIVE LOG CURRENT;

System altered.

SQL> col open_mode for a10

SQL> col FORCE_LOGGING for a10

SQL> SELECT name,open_mode,force_logging,supplemental_log_data_min FROM v$database;

NAME                OPEN_MODE  FORCE_LOGG SUPPLEMENTAL_LOG_DATA_MI

--------------------------- ---------- ---------- ------------------------

CTCN             READ WRITE YES    YES

在dbdc1为OGG单独创建TNS

这一步并不是必要的，如果OGG只负责一个database，那么可以不配置TNS

由于我这里的案例是要为多个instance做extract，因此每个extract连接不同的database，就要用到TNS

CTCN_OGG =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.24.136)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = CTCN)

    )

  )

创建OGG管理用户及其表空间

SQL> create tablespace ogg datafile '+ASM_DAT1' size 1M autoextend on maxsize 10G;

Tablespace created.

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

User created.

SQL> grant connect,resource,dba to ogg;

Grant succeeded.

配置OGG

设置OGG全局参数

[oracle@dbdc1 ~]$ cd /u01/ogg/gg/

[oracle@dbdc1 gg]$ ggsci

GGSCI (dbdc1) 1> EDIT PARAMS ./GLOBALS

GGSCHEMA ogg

Source端，OGG设置，配置管理进程

GGSCI (dbdc1) 2> EDIT PARAM MGR

PORT 7809

AUTOSTART ER *

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

LAGREPORTHOURS 1

PURGEOLDEXTRACTS /u01/ogg/datdir/*,USECHECKPOINTS,MINKEEPDAYS 1

GGSCI (dbdc1) 8> DBLOGIN userid ogg@CTCN1_OGG, password ogg

Successfully logged into database.

创建checkpoint表

GGSCI (dbdc1 as ogg@CTCN1) 9> add checkpointtable ogg.ggs_checkpoint

Successfully created checkpoint table ogg.ggs_checkpoint.

添加跟踪对象，pos下所有表

GGSCI (dbdc1 as ogg@CTCN1) 11> ADD TRANDATA pos.*

...

...

配置extract

源端是双节点RAC，此处设置参数THREADS 2

配置extract

ADD EXTRACT ext_pos1,TRANLOG,BEGIN NOW,THREADS 2

指定extract的trail位置

ADD EXTTRAIL /u01/ogg/datdir/po, EXTRACT ext_pos1 MEGABYTES 50

配置extract参数

源端是双节点RAC，此处设置参数 TRANLOGOPTIONS DBLOGREADER 

GGSCI (dbdc1 as ogg@CTCN1) 5> EDIT PARAMS ext_pos1

EXTRACT ext_pos1

USERID ogg@CTCN_OGG, PASSWORD ogg

TRANLOGOPTIONS DBLOGREADER

EXTTRAIL /u01/ogg/datdir/po

TABLE pos.*;

查看

[oracle@dbdc1 datdir]$ ll -h

total 1.2M

配置投递进程，设置本地trail

GGSCI (dbdc1) 1> ADD EXTRACT DP_pos1 EXTTRAILSOURCE /u01/ogg/datdir/po

EXTRACT added.

为投递进程DP_pos1 设置远程trail目标

GGSCI (dbdc1) 2> ADD RMTTRAIL /data/ogg_app/dirdat/po, EXTRACT DP_pos1

RMTTRAIL added.

配置DP_pos1参数文件

GGSCI (dbdc1) 3> edit param DP_pos1

EXTRACT DP_pos1

USERID ogg@CTCN_OGG, PASSWORD ogg

RMTHOST 10.18.0.41, MGRPORT 7809
