Use GoldenGate to synchronize data from MySQL to Oracle in real time

Step 1: Configure mysql
Modify the configuration file my. ini
# For goldengate
Log-bin = "C:/mysql/logbin. log"
Binlog-format = ROW
Log-bin-index = "C: \ mysql \ logindex"
Binlog_cache_size = 32 m
Max_binlog_cache_size = 512 m
Max_binlog_size = 512 m

Add Database User ggs with DBA permission

Step 2: install and configure GoldenGate on the mysql server

Step 3: Configure defgen
Create defgen Parameters
-- Defgen. prm
Defsfile C: \ ogg \ dirdef \ defgen. prm
Sourcedb test @ localhost: 3306, userid ggs, password 123
Table test. test1;

Generate the defgen File
Defgen paramfile C: \ ogg \ dirprm \ defgen. prm

Copy the file defgen. prm under the C: \ ogg \ dirdef directory to the target directory. \ dirdef.

Step 4: Prepare the Oracle environment
Create a database user
Create tablespace ggs datafile '... 'size 200 m;
Create user ggs identified by 123 default tablespace ggs;
Grant dba to ggs;

Step 5: install and configure GoldenGate on the Oracle server
Create mgr Parameters
