报错现象：

ERROR  OGG-03517  Conversion from character set zhs16gbk of source columnADDRESS to character set UTF-16 oftarget column ADDRESS fa

iledbecause the source column contains a character that is not availablein the target character set.

解决方案：

1）错误日志下方找到故障产生的队列文件和RBA号，为后天定位故障发生所在的事务

Reading./dirdat/yd000003234, current RBA 189904087, 131 records,m_file_seqno = 3234, m_file_rba = 189904087

2）通过logdump工具，检查这个SQL所在的事务，用Logdump:

./logdump

Logdump46 >open ./dirdat /yd000003234 <--上一步获取

CurrentLogTrail is /home/oracle/OGG_Target/./dirdat/yd000003234

Logdump47 >ghdr on

Logdump48 >detail data on

Logdump49 >usertoken on

Logdump50 >ggstoken detail

Logdump51 >pos 189904087 <--上一步获取

Logdump51 >n

Logdump211 >pos 189904087

Readingforward from RBA 189904087

Logdump212 >n

说明：这里已经确定这个出问题的字段是DBTEST.USERINFO表。

3）通过配置文件中对应的表进行相关配置，重启进程即可

MAPDBTEST.USERINFO,TARGET DBTEST.USERINFO,COLCHARSET(PASSTHRU,ADDRESS);

报错现象：

OGG-03533 Conversion from character set zhs16gbk of source column ADDRESS tocharacter set UTF-8 of target column ADDRESS faile

dbecause the source column contains a character 84 at offset 24 thatis not available in the target character set.

解决方案：

在参数文件中加入以下参数，并重启进程

REPLACEBADCHARESCAPE

报错现象：

Theerror message:ERROR OGG-15051 Java or JNIexception:oracle.goldengate.util.GGException: Kafka Handler failed toformat and process operation: table=[DBTEST.USERINFO], oppos=00000054270047517956, tx pos=00000054270044951614, opts=2019-04-04 11:00

解决方案：

1）修改参数文件kafka.props

如果文件中有gg.handler.kafkahandler.format.pkUpdateHandling参数，则修改为delete-insert；如果为没有gg.handler.kafkahandler.format.pkUpdateHandling参数则新添加：

gg.handler.kafkahandler.format.pkUpdateHandling=delete-insert

2）保存退出后重启进程
