OGG12实时同步oracle到mysql基础配置
系统环境
1.源库Oracle
Redhat 6.4
Oracle 11.2.0.4 RAC
IP：192.168.118.119
Ogg: Version 12.1.2.1.0
2.目标库Mysql
CentOS 6.5
Percona Server 5.7.17
IP：192.168.106.91
Ogg: Version 12.2.0.1.170221
------------------------------------------------------------------------------------------
Oracle源库配置
1.配置提取进程参数
GGSCI (cktsdb1) 8> view params ex3
extract ex3
tranlogoptions dblogreader
dynamicresolution
userid oggadmin,password oggadmin123
exttrail dirdat/xs
table test.t1;
GGSCI (cktsdb1) 9> add extract ex3,tranlog,begin now,threads 2
EXTRACT added.
GGSCI (cktsdb1) 10> add exttrail dirdat/xs,extract ex3 megabytes 5
EXTTRAIL added.
2.配置投递进程参数
GGSCI (cktsdb1) 13> view params dp3
extract dp3
passthru
dynamicresolution
userid oggadmin,password oggadmin123
rmthost 192.168.106.91,mgrport 7809
rmttrail dirdat/xs
table test.t1;
GGSCI (cktsdb1) 15> add extract dp3 exttrailsource dirdat/xs
EXTRACT added.
GGSCI (cktsdb1) 16> add rmttrail dirdat/xs,extract dp3
RMTTRAIL added.
3.配置define文件
因为是异构，所以define作为2个数据库这间表的关系映射
GGSCI (cktsdb1) 1> edit params t1
defsfile dirdef/t1.prm
userid oggadmin,password oggadmin123
table test.t1；
生成define文件
[oracle@cktsdb1 ogg]$ ./defgen paramfile dirprm/t1.prm

table test.t1;
Retrieving definition for TEST.T1.

4.复制define文件到Mysql数据库主机
[root@cktsdb1 ogg]# scp dirdef/t1.prm 192.168.106.91:/home/mysql/dirdef
[email protected]'s password:
t1.prm 0% 0 0.0KB/s --:-- ETA
t1.prm 100% 1182 1.2KB/s 00:00
------------------------------------------------------------------------------------------
Mysql目标库配置
1.创建源库对应的表t1
mysql> create table t1(id int,name varchar(10),primary key(id));
Query OK, 0 rows affected (0.03 sec)
show tables
+----------------+
| Tables_in_test |
+----------------+
| dep |
| emp |
| t1 |
+----------------+
2.创建目录create subdirs
[mysql@cqgs_ywjk ~]$ unzip GOLDENGATE\ V12.2.0.1.170221\ FOR\ MySQL_Linux-x86-64.zip
[mysql@cqgs_ywjk ~]$tar -xvf ggs_Linux_x64_MySQL_64bit.tar
[mysql@cqgs_ywjk ~]$ ./ggsci

GGSCI (cqgs_ywjk) 1> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER STOPPED
GGSCI (cqgs_ywjk) 3> create subdirs
Creating subdirectories under current directory /home/mysql
Parameter files /home/mysql/dirprm: created
Report files /home/mysql/dirrpt: created
Checkpoint files /home/mysql/dirchk: created

3.配置启动mgr
GGSCI (cqgs_ywjk) 5> edit params mgr
PORT 7809
dynamicportlist 7840-7914
autorestart extract *,retries 5,waitminutes 7
purgeoldextracts ./dirdat/*,usecheckpoints,minkeepdays 10

accessrule,prog server,allow
GGSCI (cqgs_ywjk) 7> start mgr
Manager started.
GGSCI (cqgs_ywjk) 8> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
4.配置checkpoint table
GGSCI (cqgs_ywjk DBLOGIN as root) 14> edit params ./globals
CHECKPOINTTABLE test.checkpoint
登陆
GGSCI (cqgs_ywjk) 13> dblogin SOURCEDB test,userid root
Password:
Successfully logged into database.
由于Ogg默认是找/tmp/mysql.sock
ln -s ln -s /mysql/Percona/data/mysql.sock /tmp/mysql.sock /tmp/mysql.sock
GGSCI (cqgs_ywjk DBLOGIN as root) 16> add checkpointtable test.checkpointtab
Successfully created checkpoint table test.checkpointtab.
GGSCI (cqgs_ywjk DBLOGIN as root) 16> info checkpointtable test.checkpointtab
查看Mysql可以看到checkpointtab等表被添加
mysql> use test
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> show tables;
+-------------------+
| Tables_in_test |
+-------------------+
| checkpointtab |
| checkpointtab_lox |
| dep |
| emp |
| t1 |
+-------------------+
5.配置复制进程
GSCI (cqgs_ywjk DBLOGIN as root) 43> edit params rep1
replicat rep1
sourcedefs dirdef/t1.prm
TRAGETDB test,userid root,password root1234
reperror default,discard
discardfile dirrpt/rep4.dsc,append,megabytes 50
map test.t1, target test.t1;
GGSCI (cqgs_ywjk DBLOGIN as root) 28> add replicat rep1,exttrail dirdat/xs,checkpointtable test.checkpointtab
6.修改从源数据库复制过来的define文件权限
[root@cqgs_ywjk dirdef]# chown -R mysql:mysql t1.prm
数据测试
1.初始化数据
a.两边数据清空。
b.文本导入导出
c.使用ogg direct load方式
2.启动复制进程
GGSCI (cqgs_ywjk DBLOGIN as root) 44> start rep1
Sending START request to MANAGER ...
REPLICAT REP1 starting
GGSCI (cqgs_ywjk DBLOGIN as root) 45> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
REPLICAT RUNNING REP1 00:00:00 00:00:01
3.启动抽取和投递进程
GGSCI (cktsdb1) 8> start ex3
Sending START request to MANAGER ...
EXTRACT EX3 starting
GGSCI (cktsdb1) 9> start dp3
Sending START request to MANAGER ...
EXTRACT DP3 starting
GGSCI (cktsdb1) 16> info all
Program Status Group Lag at Chkpt Time Since Chkpt
