使用GoldenGate实现MySQL到Oracle的数据实时同步
step 1: 配置mysql
修改配置文件my.ini
#for goldengate
log-bin = "C:/mysql/logbin/logbin.log"
binlog-format = ROW
log-bin-index = "C:mysqllogindex"
binlog_cache_size=32m
max_binlog_cache_size=512m
max_binlog_size=512m
添加数据库用户ggs，具有DBA权限
step 2: 在mysql服务器上安装配置GoldenGate
创建mgr.prm
PORT 7809
DYNAMICPORTLIST 7840-7914
STARTUPVALIDATIONDELAY 5
PURGEOLDEXTRACTS C:oggdirdat*, USECHECKPOINTS, MINKEEPDAYS 7

创建抽取进程参数ext1.prm
--ext1.prm
EXTRACT ext1

ADD EXTRACT ext1, tranlog, begin now
ADD EXTTRAIL C:oggdirrptex, EXTRACT ext1, megabytes 100
创建传播进程参数dp1.prm
--dp1.prm
EXTRACT dp1

添加抽取进程dp1
ADD EXTRACT dp1, EXTTRAILSOURCE C:oggdirdatex
ADD RMTTRAIL d:oggdirdatex, EXTRACT dp1, MEGABYTES 100
step 3: 配置defgen
创建defgen参数
--defgen.prm
defsfile C:oggdirdefdefgen.prm
sourcedb test@localhost:3306, userid ggs,password 123
table test.test1;
生成defgen文件
defgen paramfile C:oggdirprmdefgen.prm
将C:oggdirdef目录下的文件defgen.prm拷贝到目标端的相应目录下，即目录.dirdef下。
step 4: Oracle环境准备
创建数据库用户
create tablespace ggs datafile '......' size 200m;
create user ggs identified by 123 default tablespace ggs;
grant dba to ggs;
step 5: 在Oracle服务器安装配置GoldenGate
创建mgr参数
--mgr.prm
PORT 7809
DYNAMICPORTLIST 7840-7914
STARTUPVALIDATIONDELAY 5
PURGEOLDEXTRACTS d:oggdirdat*, USECHECKPOINTS, MINKEEPDAYS 7

创建复制进程参数rep1.prm
--rep1.prm
replicat rep1
sourcedefs D:oggdirdefdefgen.prm
userid ggs,password ggs
reperror default,discard
discardfile D:oggdirrptrep1.dsc,append,megabytes 50
dynamicresolution
map test.test1, target test.test1;
添加复制进程
dblogin userid ggs password 123
add checkpointtable chkpnttab
add replicat rep1,exttrail D:oggdirdatex, checkpointtable chkpnttab
