GoldenGate学习之--异构平台同步(到Oracle)
如图所示:源端采用Mysql库,目标端采用Oracle库
一、OGG安装配置(源端)
1、OGG下载
[oracle@ogg ogg_ms]$ uname -a

二、配置
源端:mysql库配置

三、OGG同步配置
源端:Mysql库配置

附录:解决方法(参考网络文档)
GoldenGate的官方文档明确表示,GoldenGate需要将MySQL的日志格式(binlog_format)设置为ROW,其他两种格式(MIXED or STATEMENT)是不支持。
########################################################################官方描述如下:
binlog_format: This parameter sets the format of the logs. It must be set to the value of ROW, which directs the database to log DML statements in binary format. Any other log format (MIXED or STATEMENT) causes Extract to abend.
########################################################################
但是MySQL在版本5.1.5之前是不支持ROW和MIXED格式(MySQL 5.1.5引入ROW,5.1.8引入MIXED)
#### 官方描述如下:
Support for row-based logging was added in MySQL 5.1.5. Mixed logging is available beginning with MySQL 5.1.8. In MySQL 5.1.12,MIXED become the default logging mode; in 5.1.29, the default was changed back to STATEMENT for compatibility with MySQL 5.0.
########################################################################
目前客户的MySQL版本是5.0.6-beta版:
D:\MySQL Server 5.0\bin>mysql -u root -p
Enter password: *****
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 111 to server version: 5.0.6-beta-nt-log
Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the buffer.
mysql> select version();
+-------------------+
| version() |
+-------------------+
| 5.0.6-beta-nt-log|
+-------------------+
1 row in set (0.02 sec)
这个版本是不支持binlog_format=ROW,所以安装好GolenGate后,启动抽取进程时,进程abend
########################################################################下面是出错信息:
2014-09-16 16:55:16 ERROR OGG-00146 VAM function VAMRead returned unexpected result: error 600 - VAM Client Report <CAUSE OF FAILURE : STATEMENT or MIXED level logging found so abending
WHEN FAILED : While reading log event from binary log
WHERE FAILED : MySQLBinLog Reader Module
CONTEXT OF FAILURE : No Information Available!>
因此如果想要采用GoldenGate来实现MySQL的数据实时同步,需要将MySQL版本升级到5.1.5以上.
四、目标端ogg配置

由于源端extract进程异常,数据不能同步,问题未解决,欢迎指导,待续...
问题解决:
更换mysql-5.5.12的版本,目前Golden Gate 版本不支持mysql-5.6
GGSCI (ogg) 1> edit param ext_1
配置/etc/my.cnf文件:
# binary logging is required for replicationlog-bin=/var/lib/mysql/mysql-binlog-bin-index=/var/lib/mysql/mysql-bin.index# binary logging format - mixed recommended#binlog_format=mixedbinlog_format=row
并编辑extract进程组配置文件
GGSCI (ogg) 1> edit param ext_1
extract ext_1
setenv (MYSQL_HOME=”/var/lib/mysql”)
tranlogoptions altlogdest /var/lib/mysql/mysql-bin.index
sourcedb test@localhost:3306,userid root,password oracle
exttrail ./dirdat/e2
dynamicresolution
gettruncates
table test.test2;
启动extract 进程
