一、安装oracle数据库,配置远程桌面 (略)
源 和 目标 环境都如下:
(1) 数据库
(2)监听
(3) TNSNAME 文件配置
tnsname.ora 文件内容,后面很多配置基于这个配置:
##CDB YUNGG = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.180)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = yun) ) ) ##PDB YUNGGXC = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.180)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = xiaochong) ) )
二、 解压安装glodengate软件
以下步骤,通过oracle用户执行
(1) 创建安装目录:
(创建源端安装目录)
mkdir -p /u01/app/oracle/product/ogg_src
(创建目标端安装目录)
mkdir -p /u01/app/oracle/product/ogg_trg
(2) 修改oracle用户环境变量
vim ~/.bash_profile
#添加如下内容 (源和目标端的路径不同,这里以源端为例): export OGG_HOME=/u01/app/oracle/product/ogg_src export PATH=$OGG_HOME:$PATH export LD_LIBRARY_PATH=$OGG_HOME:$LD_LIBRARY_PATH
使之生效:
source ~/.bash_profile
(3)解压安装包(root)
(4) 图形界面安装 (源端安装,目标直接拷贝安装好的文件目录即可)
将安装文件目录拷贝到目标端,这样目标端就可以免安装了
[oracle@yun@oggp:ogg_src]scp -r * oracle@192.168.56.180:/u01/app/oracle/product/ogg_trg/
(5)测试
登录GGSCI
三、准备
1. 流程图:
2. 创建数据库用户
此用户为glodengate管理用户,在12C的容器数据库环境下,需要在CDB库下创建。
create tablespace goldengate datafile size 8M autoextend on; create user c##goldengate identified by goldengate default tablespace goldengate; grant dba to c##goldengate; exec dbms_goldengate_auth.grant_admin_privilege('c##goldengate');
测试连接:
这里容易错误的地方:
(1)在CDB环境中创建公共用户,需要以C##或c##开头,且PDB中不能用有剔除C##后相同的用户名。
(2)赋权需要在CDB和PDB都要执行
(3)如果需要指定表空间,必须在CDB和所有PDB中创建相同的表空间。不然会报如下错误。
ORA-65096,ORA-65048,ORA-00959
Warning: PDB altered with errors.
有一点不明白:删除了pdb里重复的用户,重启创建公共用户,重启系统后,pdb中公共用户失效。
如下: C##OGG 用户,而重新定义的用户C##OGGP是没有问题的
SQL> show pdbs CON_ID CON_NAME OPEN MODE RESTRICTED ---------- ------------------------------ ---------- ---------- 2 PDB$SEED READ ONLY NO 3 XIAOCHONG READ WRITE NO SQL> select username,common,con_id from cdb_users where username like '%OGG%'; USERNAME COMMON CON_ID C##OGG YES 1 C##OGGP YES 1 C##OGGP YES 3 SQL> alter session set container=xiaochong; Session altered. SQL> select username,common,con_id from cdb_users where username like '%OGG%'; USERNAME COMMON CON_ID C##OGGP YES 3
3. 修改源库日志模式 并 开启附加日志
(1)修改:
修改归档(略)
SQL> alter database force logging;
Database altered.
SQL> alter system set enable_goldengate_replication=true;
System altered.
---开启附加日志
SQL> alter database add supplemental log data;
Database altered.
(2)查询
--确认开启数据库级附加日志
SQL> select supplemental_log_data_min from v$database; SUPPLEMENTAL_LOG_DATA_MI ------------------------ YES
--确认已经开启归档
SQL> archive log list Database log mode Archive Mode Automatic archival Enabled Archive destination USE_DB_RECOVERY_FILE_DEST Oldest online log sequence 52 Next log sequence to archive 54 Current log sequence 54
四、配置
1. 配置全局参数 (源端,目标端都配置)
GGSCI (oggp) 1> edit param ./GLOBALS ##添加如下内容: GGSCHEMA C##GOLDENGATE
2. 配置Manager
(1)源端:
(2)目标端(因为是指向拷贝文件的,默认没有运行,需要开启)
2. 配置local extract
(1)配置参数
连接CDB,注意test为用户,t1为表名,后面以分好结尾。
(2)开启表级附加日志
(3) 添加进程
容器数据库必须是集成模式(integrated)
(3)注册PDB
(4)添加tail文件
(5)开启进程
(6)测试
将T表插入一条记录后,
GGSCI (oggp as C##goldengate@yun/CDB$ROOT) 18> stats ext exttest Sending STATS request to EXTRACT EXTTEST ... Start of Statistics at 2019-06-13 15:42:07. Output to ./dirdat/ex: Extracting from XIAOCHONG.TEST.T to XIAOCHONG.TEST.T: *** Total statistics since 2019-06-13 15:41:21 *** Total inserts 1.00 Total updates 0.00 Total deletes 0.00 Total discards 0.00 Total operations 1.00 *** Daily statistics since 2019-06-13 15:41:21 *** Total inserts 1.00 Total updates 0.00 Total deletes 0.00 Total discards 0.00 Total operations 1.00 *** Hourly statistics since 2019-06-13 15:41:21 *** Total inserts 1.00 Total updates 0.00 Total deletes 0.00 Total discards 0.00 Total operations 1.00 *** Latest statistics since 2019-06-13 15:41:21 *** Total inserts 1.00 Total updates 0.00 Total deletes 0.00 Total discards 0.00 Total operations 1.00
End of Statistics.
3. 配置data Pump
(1) 配置参数
(2) 添加进程
(3) 添加trail文件
(4) 开启进程
(5) 测试
GGSCI (oggp) 6> stats ext dptest Sending STATS request to EXTRACT DPTEST ... Start of Statistics at 2019-06-13 16:01:46. Output to ./dirdat/dp: Extracting from XIAOCHONG.TEST.T to XIAOCHONG.TEST.T: *** Total statistics since 2019-06-13 15:57:31 *** Total inserts 1.00 Total updates 0.00 Total deletes 0.00 Total discards 0.00 Total operations 1.00 *** Daily statistics since 2019-06-13 15:57:31 *** Total inserts 1.00 Total updates 0.00 Total deletes 0.00 Total discards 0.00 Total operations 1.00 *** Hourly statistics since 2019-06-13 15:57:31 *** Total inserts 1.00 Total updates 0.00 Total deletes 0.00 Total discards 0.00 Total operations 1.00 *** Latest statistics since 2019-06-13 15:57:31 *** Total inserts 1.00 Total updates 0.00 Total deletes 0.00 Total discards 0.00 Total operations 1.00 End of Statistics.
4. 目标端配置checkpoint table
5. 配置replicat
(1)配置参数
(2)添加进程
(3)开启进程
(4)测试
GGSCI (oggs as c##goldengate@yun/XIAOCHONG) 51> stats rep reptest Sending STATS request to REPLICAT REPTEST ... Start of Statistics at 2019-06-13 17:03:39. Replicating from XIAOCHONG.TEST.T to XIAOCHONG.TEST.T: *** Total statistics since 2019-06-13 17:03:35 *** Total inserts 2.00 Total updates 0.00 Total deletes 0.00 Total discards 0.00 Total operations 2.00 *** Daily statistics since 2019-06-13 17:03:35 *** Total inserts 2.00 Total updates 0.00 Total deletes 0.00 Total discards 0.00 Total operations 2.00 *** Hourly statistics since 2019-06-13 17:03:35 *** Total inserts 2.00 Total updates 0.00 Total deletes 0.00 Total discards 0.00 Total operations 2.00 *** Latest statistics since 2019-06-13 17:03:35 *** Total inserts 2.00 Total updates 0.00 Total deletes 0.00 Total discards 0.00 Total operations 2.00 End of Statistics.
最终测试: 自行测试即可。
