One-way replication from ORACLE to mysql through goldengate

Source: Internet
Author: User
One-way replication environment from ORACLE to mysql using goldengate: I use the VBOX virtual machine, a host that has installed the ORACLE database and GOLDENDGATE. The other one only installs the ORACLE database. Configure the database environment, goldengate users, and install goldengate. For more information, see blog. csdn. netq947817003articledeta.

Environment: I use the VBOX virtual machine, a host that has installed the ORACLE database and GOLDENDGATE. The other one only installs the ORACLE database.

1. Install MYSQL to install the MYSQL database client: [root @ bys2 ~] # Mount/dev/cdrom/mnt/cdrom/
Mount: block device/dev/cdrom is write-protected, mounting read-only
[Root @ bys2 ~] # Rpm-qa mysql
[Root @ bys2 ~] # Cd/mnt/cdrom/
[Root @ bys2 cdrom] # yum-y install mysql
Install the server
[Root @ bys2 cdrom] # yum-y install mysql-server
[Root @ bys2 cdrom] # rpm-qa mysql *

After exiting, use [oracle @ bys2 mysqlogg] $ mysql-u root-p for the login test. Then, confirm that you can log on using the root user and password.
If you cannot log on, you can refer to: http://blog.csdn.net/q947817003/article/details/13295099

2. Install OGG-FOR-MYSQL
[Oracle @ bys2 ~] $ Tar-xvf ggs_Linux_x86_MySQL_32bit.tar-C/u01/mysqlogg/
[Oracle @ bys2 mysqlogg] $ pwd

3. Configure the target OGG. First, plan that the PORT started by the target database is 7810. MYSQL sets the table TEST5 of the oggtest database to be synchronized,
The ORACLE source uses the TEST5 table of user TEST5.
1. Configure the MGR process GGSCI (bys2.oel.com) 4> edit params mgr
PORT 7810
PURGEOLDEXTRACTS./dirdat, USECHECKPOINTS, MINKEEPDAYS 10

GGSCI (bys2.oel.com) 2> edit params./globals
Eckpointtable oggtest. chktab
2. log on to and configure the replicat process GGSCI (bys2.oel.com) 1> dblogin sourcedb oggtest, userid root
Password:
Successfully logged into database.
Run these two commands:
Add checkpointtable oggtest. chktab
Add replicat repmysql, exttrail/u01/mysqlogg/dirdat/my, checkpointtable oggtest. chktab

Edit configuration file
Edit params repmysql
The content of the -- MAPS statement is as follows:
Replicat repmysql
Sourcedefs./dirdef/to_mysql.def
Handlecollisions
Assumetargetdefs
Applynoopupdates
Sourcedb oggtest, userid root, password 123456
Discardfile./dirdat/repmysql. dsc, append, megabytes 50
Map test5.test5, target oggtest. test5;
4. Configure the source database-do not use the PUMP method. 1. The MGR process has been configured. Configure the extract process to perform the following operations in sequence:
Add extract extmysql, tranlog, begin now

Location of the target file -- here, note that rmttrail refers to the path of the target file.
Add rmttrail/u01/mysqlogg/dirdat/my, extract extmysql

Edit params extmysql
Write Data in the open edit window
Extract extmysql
Userid ogg, password ogg
Rmthost 192.168.1.213, mgrport 7810
Rmttrail/u01/mysqlogg/dirdat/my
Table test5.test5;
2. generate an object definition file on the source database and copy the file to GGSCI (node1.example.com) 21> edit params defgen under ogg/dirdef of the target database (MYSQL ).

Defsfile./dirdef/to_mysql.def
Userid ogg, password ogg
Table test5.test5;

[Oracle @ bys001 ogg] $./defgen paramfile./dirprm/defgen. prm
[Oracle @ bys001 dirdef] $ pwd
/U01/ogg/dirdef
[Oracle @ bys001 dirdef] $ ls
To_mysql.def
[Oracle @ bys001 dirdef] $ scp to_mysql.def 192.168.1.213:/u01/mysqlogg/dirdef
To_mysql.def 100% 912 0.9KB/s

5. When initializing the data and opening the initialization data of both processes, create the corresponding user and table.
Create the TEST5 table of the oggtest database in the target MYSQL database,
The ORACLE source uses the TEST5 table of user TEST5.

The statement used to create users and tables in the replicel database is as follows:
Run create user test5 inentified by test5 as the DBA user;
Grant connect, resource to test5;
Conn test5/test5
Create table test5 (aa int primary key );
The statement used in MYSQL is as follows: -- the first step has been executed.
Mysql> create database oggtest;
Mysql> use oggtest;
Mysql> grant all privileges on *. * to 'root' @ '% 'identified by '123 ';
Mysql> grant all privileges on *. * to 'ogn' @ '% 'identified by 'ogn ';
Mysql> flush privileges;
Mysql> use oggtest
Mysql> create table test5 (aa int primary key) engine = innodb;

The statements used to open a process are roughly as follows:
Start mgr
Start extract extmysql or start extmysql
Start replicat repmysql or start repmysql
The status of both processes is as follows:
Source end:EXT1 EXT3 PUMP3 REP2 is used to configure other replication operations. Do not worry about ORACLE-MYSQL replication.

MYSQL:

Submit twice in the ORACLE database. In MYSQL, The chktab, audit_ts column, and last_update_ts column are all updated. It may be that ORACLE and MYSQL are not on the same host and the time is not synchronized. The update time on both ends is inconsistent.
