2014-09-26 17:24:56 ERROR OGG-01668 Oracle GoldenGate Capture for MySQL, ext_1.prm: PROCESS ABENDING.

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：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.

########################################################################

目前客户的MySQL版本是5.0.6-beta版：

D:MySQL Server 5.0bin>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

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.

GGSCI (rh6.cuug.net) 6> info mgr

Manager is running (IP port rh6.cuug.net.7809).

配置replicat进程组：

[oracle@rh6 ogg]$ ./ggsci

Oracle GoldenGate Command Interpreter for Oracle

Version 11.2.1.0.1 OGGCORE_11.2.1.0.1_PLATFORMS_120423.0230_FBO

Linux, x86, 32bit (optimized), Oracle 11g on Apr 23 2012 08:09:25

GGSCI (rh6.cuug.net) 1>

GGSCI (rh6.cuug.net) 1> edit param rep_1

replicat rep_1

sourcedefs /u01/ogg/dirdef/defgen.prm

userid ogg,password ogg

reperror default,discard

discardfile /u01/ogg/dirrpt/rep_1.dsc,append,megabytes 50

dynamicresolution

map test.test2, target test.test2;

GGSCI (rh6.cuug.net) 1> add replicat rep_1,exttrail /u01/ogg/dirdat/e2

REPLICAT added.

启动mgr和replicat进程：

GGSCI (rh6.cuug.net) 3> start mgr

Manager started.

GGSCI (rh6.cuug.net) 4> info all

Program Status Group Lag at Chkpt Time Since Chkpt

MANAGER RUNNING

REPLICAT STOPPED REP_1 00:00:00 00:00:34

GGSCI (rh6.cuug.net) 5> start replicat rep_1

Sending START request to MANAGER ...

REPLICAT REP_1 starting

GGSCI (rh6.cuug.net) 6> info all

Program Status Group Lag at Chkpt Time Since Chkpt

MANAGER RUNNING

REPLICAT RUNNING REP_1 00:00:00 00:00:00

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 replication

log-bin=/var/lib/mysql/mysql-bin

log-bin-index=/var/lib/mysql/mysql-bin.index

# binary logging format - mixed recommended

#binlog_format=mixed

binlog_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GGSCI (ogg) 2> start ext_1

Sending START request to MANAGER ...

EXTRACT EXT_1 starting

GGSCI (ogg) 3> info all

Program Status Group Lag at Chkpt Time Since Chkpt

MANAGER RUNNING

EXTRACT ABENDED EXT_1 00:00:00 72:19:40
