此次试验是为了某省电力公司OGG初始化模拟演练。演练过程分为两篇博客记录全过程。第一篇是安装配置，主要介绍OGG在源端和灾备端都是双节点RAC下的配置。第二篇是OGG初始化，使用rman恢复灾备端数据库，启用OGG复制进程追加日志。
环境介绍：
Source Target
| OS:Enterprise Linux Server release 5.7 OGG: 11.2.1.0.1 ORACLE: 11.2.0.4 RAC 双节点 172.16.228.101 node1 172.16.228.102 node2 OGG路径 node1 /goldengate | OS:Enterprise Linux Server release 5.7 OGG 11.2.1.0.1 ORACLE: 11.2.0.4 RAC 双节点 172.16.228.103 node3 172.16.228.104 node4 OGG路径 node3 /goldengate |
Source系统设置
1.在node1解压缩ogg安装包
| # su - oracle [oracle@node1 ~]$ cd /goldengate/ [oracle@node1 goldengate]$ unzip /tmp/ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip [oracle@node1 goldengate]$ tar xvf fbo_ggs_Linux_x64_ora11g_64bit.tar |
2.在bash_profile中添加OGG_HOME
| su - oraclecdvi .bash_profile export ORACLE_HOSTNAME=node1 export ORACLE_SID=PROD1 export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 export ORACLE_UNQNAME=PROD export OGG_HOME=/goldengate export TNS_ADMIN=$ORACLE_HOME/network/admin export ORACLE_TERM=xterm export PATH=/usr/sbin:$PATH export PATH=$ORACLE_HOME/bin:$PATH:$OGG_HOME export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib: export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib export EDITOR=vi export LANG=en_US export NLS_LANG=american_america.AL32UTF8 export NLS_DATE_FORMAT='yyyy/mm/dd hh34:mi:ss' |
3.创建OGG应用目录,该操作需要在OGG_HOME路径下
| cd $OGG_HOME [oracle@node1 goldengate]$ ggsci GGSCI (node1) 1> CREATE SUBDIRS |
4.数据库开启归档模式
| 查看是否为归档模式archive log list;开启归档模式# srvctl stop database -d prodSQL> startup mount;SQL> alter database archivelog;SQL> shutdown immediate;# srvctl start database -d prod |
5.开启数据库级别日志补充
| sqlplus / as sysdba SQL> ALTER DATABASE FORCE LOGGING; SQL>ALTER DATABASE ADD SUPPLEMENTAL LOG DATA; SQL>ALTER DATABASE ADD SUPPLEMENTAL LOG DATA(PRIMARY KEY, UNIQUE,FOREIGN KEY) COLUMNS; SQL>ALTER SYSTEM ARCHIVE LOG CURRENT; SELECT SUPPLEMENTAL_LOG_DATA_MIN, SUPPLEMENTAL_LOG_DATA_PK, SUPPLEMENTAL_LOG_DATA_UI, SUPPLEMENTAL_LOG_DATA_FK, SUPPLEMENTAL_LOG_DATA_ALL FROM v$database; SUPPLEME SUP SUP SUP SUP -------- --- --- --- --- YES YES YES YES NO |
Oracle11.2.0.4版本所需参数
SQL> ALTER SYSTEM SET ENABLE_GOLDENGATE_REPLICATION = TRUE SCOPE=BOTH;
6.创建测试用户
| sqlplus / as sysdba SQL >CREATE USER snow IDENTIFIED BY snow DEFAULT TABLESPACE USERS; SQL >GRANT CONNECT, RESOURCE TO snow; SQL >conn snow/snow SQL >CREATE TABLE t1 (id INT PRIMARY KEY, name VARCHAR2(10)); |
7.创建OGG管理用户oggadmin及其表空间goldengate
| sqlplus / as sysdba SQL >select name from v$datafile; SQL >CREATE TABLESPACE goldengate DATAFILE '+DATA' SIZE 100M AUTOEXTEND ON; SQL >CREATE USER oggadmin IDENTIFIED BY oggadmin DEFAULT TABLESPACE goldengate; SQL >GRANT dba TO oggadmin; |
8.添加角色
| cd $OGG_HOME sqlplus / as sysdba SQL >@/goldengate/role_setup Enter GoldenGate schema name:oggadmin GRANT GGS_GGSUSER_ROLE TO oggadmin; |
9.安装sequence支持
| cd $OGG_HOMEsqlplus / as sysdbaSQL> @sequence.sqlSQL> GRANT EXECUTE ON oggadmin.updateSequence TO oggadmin;SQL> ALTER TABLE sys.seq$ ADD SUPPLEMENTAL LOG DATA (PRIMARY KEY) COLUMNS; |
10.设置全局参数
| cd $OGG_HOME ggsci GGSCI> EDIT PARAMS ./GLOBALS GGSCHEMA oggadmin |
Target系统设置
11.在node3解压缩ogg安装包
| # su - oracle [oracle@node3 ~]$ cd /goldengate/ [oracle@node3 goldengate]$ unzip /tmp/ogg112101_fbo_ggs_Linux_x64_ora11g_64bit.zip [oracle@node3 goldengate]$ tar xvf fbo_ggs_Linux_x64_ora11g_64bit.tar |
12.在bash_profile中添加OGG_HOME
| su - oracle cd vi .bash_profile export ORACLE_HOSTNAME=node3 export ORACLE_SID=PROD1 export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 export ORACLE_UNQNAME=PROD export OGG_HOME=/goldengate export TNS_ADMIN=$ORACLE_HOME/network/admin export ORACLE_TERM=xterm export PATH=/usr/sbin:$PATH export PATH=$ORACLE_HOME/bin:$PATH:$OGG_HOME export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib: export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib export EDITOR=vi export LANG=en_US export NLS_LANG=american_america.AL32UTF8 export NLS_DATE_FORMAT='yyyy/mm/dd hh34:mi:ss' |
13.创建OGG应用目录,该操作需要在OGG_HOME路径下
| cd $OGG_HOME [oracle@node1 goldengate]$ ggsci GGSCI (node1) 1> CREATE SUBDIRS |
14.数据库开启归档模式
| 查看是否为归档模式 archive log list; 开启归档模式 # srvctl stop database -d prod SQL> startup mount; SQL> alter database archivelog; SQL> shutdown immediate; # srvctl start database -d prod |
15.创建测试用户
| sqlplus / as sysdba SQL >CREATE USER snow IDENTIFIED BY snow DEFAULT TABLESPACE USERS; SQL >GRANT CONNECT, RESOURCE TO snow; SQL >conn snow/snow SQL >CREATE TABLE t1 (id INT PRIMARY KEY, name VARCHAR2(10)); |
