附錄：解決方法（參考網絡文檔）
GoldenGate的官方文檔明確表示，GoldenGate需要將MySQL的日志格式（binlog_format）設置為ROW，其他兩種格式（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：http://dev.mysql.com/doc/refman/5.1/en/binary-log-formats.html
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.
########################################################################
目前客戶的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)
這個版本是不支持binlog_format=ROW，所以安裝好GolenGate后，啟動抽取進程時，進程abend
########################################################################下面是出錯信息：
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來實現MySQL的數據實時同步，需要將MySQL版本升級到5.1.5以上.
四、目標端ogg配置
配置MGR GGSCI?(rh6.cuug.net)?4>?edit?params?mgr port?7809 dynamicportlist?7800-8000 autorestart?extract?*,waitminutes?2,resetminutes?5 ~ GGSCI?(rh6.cuug.net)?5>?start?mgr Manager?started.

? ?由于源端extract進程異常，數據不能同步，問題未解決，歡迎指導，待續...
問題解決：
更換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：
[java]?view plaincopyprint?并編輯extract進程組配置文件
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;
啟動extract 進程
[java]?view plaincopyprint?仍然失敗，以下為ogg日志：
[root@ogg ogg_ms]# tail ggserr.log
[java]?view plaincopyprint?
重新刪除extract進程組，重新添加
[java]?view plaincopyprint?extract進程，啟動成功！
查看日志：
-bash-4.1$ tail? ggserr.log
[java]?view plaincopyprint?總結
