GoldenGate现在是业内成熟的数据容灾与复制产品;GoldenGate是一种基于日志的结构化数据复制方式,它通过解析源数据库在线日志或归档日志获得数据的增删改变化(数据量只有日志的四分之一左右),再将这些变化应用到目标数据库,实现源数据库与目标数据库同步、双活。
目标在linux系统下安装Oracle;利用GoldenGate 实现数据同步;可复制DML和DDL操作
环境如下:本环境目标端是源端的克隆;步骤请参考第8篇
源端 | 目标端 | |
操作系统 | linux6.5 | linux6.5 |
IP | 192.168.1.235 | 192.168.1.221 |
数据库版本 | 11.2.0.4.0 | 11.2.0.4.0 |
GoldenGate版本 | 11.2.1.0.1 | 11.2.1.0.1 |
useradd -u 1003 -g oinstall -G dba ogg passwd ogg
source /home/oracle/.bash_profile # or export ORACLE_BASE=/u01/app export ORACLE_HOME=$ORACLE_BASE/oracle export ORACLE_SID=ora221 export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin/data/ogg export NLS_LANG=AMERICAN_AMERICA.UTF8 export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH alias sqlplus=‘rlwrap sqlplus‘ alias ggsci=‘rlwrap ggsci‘
mkdir -p /data/ogg chown -R ogg:oinstall /data/ogg
unzip fbo_ggs_Linux_x64_ora11g_64bit.tar.zip tar -xvf fbo_ggs_Linux_x64_ora11g_64bit.tar -C /data/ogg
create tablespace tsp_ogg datafile ‘/data/oracle/data/ogg01.dbf‘ size 100M autoextend on;
create user ogg identified by ogg default tablespace tsp_ogg; grant dba to ogg; GRANT CREATE TABLE,CREATE SEQUENCE TO OGG;
alter system set log_archive_dest_1 = ‘LOCATION=/data/arch‘ scope = spfile; shutdown immediate; startup mount alter database archivelog; alter database open;
还需要开启 force log 和 supplemental log
alter database force logging; alter database add SUPPLEMENTAL log data;
最后查询结果如下:
SQL> select NAME,OPEN_MODE,FORCE_LOGGING,SUPPLEMENTAL_LOG_DATA_MIN from v$database; NAME OPEN_MODE FOR SUPPLEME --------- -------------------- --- -------- ORA235 READ WRITE YES YES
@marker_setup.sql @ddl_setup.sql @role_setup.sql @ddl_enable.sql
在11.2.0.4.0版本;需要设置
ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION = TRUE SCOPE=BOTH;
只有commit之后的日志信息才会被Capture进程捕获,未提交的事务OGG不会捕获。
