1、IP限制因其的目标端拒绝源端进程
源端告警：view report ext_1
ERROR OGG-01201 Error reported by MGR : Access denied.

目标端告警: view report mgr

WARNING OGG-00936 Oracle GoldenGate Manager for Oracle, mgr.prm: Access denied (request from 172.41.176.102, rule #0).
解决：
可以看到是目标端mgr主动拒绝了源端extract启动replicat进程repinit。
后进过查询资料，这是由于GoldenGate 12.2的新特性导致的，要想可以通过远程启动目标端的replicat进程，需要在mgr配置文件中增加参数如下：
执行
GGSCI (custom04) 3> EDIT PARAMS MGR
添加
ACCESSRULE, PROG *, IPADDR 172.41.176.102 ALLOW
注意：IPADDR 后面IP是根绝Report mgr 面的IP填写
2、命令“MAP”未以分号结尾
源端告警：view report ext_1
ERROR OGG-00396 Command "MAP" not terminated by semi-colon
解决：
在目标服务器执行下面语句：
GGSCI (custom04) 3> EDIT PARAMS RINI_1
修改MAP命令，最后添加一个分号;
MAP marvin.*,TARGET mvschema. *;
3、无法打开检查点文件
源端警告 ：view report ext_1

4、数据库操作失败：无法连接到 ODBC
源端警告 ：view report ext_1

解决：在目标服务器执行如下语句
GGSCI (custom04) 3> EDIT PARAMS RINI_1
修改TARGETDB 为ODBC的连接字符串名称
将原配置
TARGETDB EMP USERID sa, PASSWORD sa123456
修改为
TARGETDB Oracle USERID sa, PASSWORD sa123456
5、目标端未有同样表结构的数据表存在，导致无法进行数据同步
利用OGG进程数据初始化源端警告：view report ext_1
OGG-01194 EXTRACT task RINI_1 abended : Table mvschema.MARVIN does not exist in target database
原因：是由于目标端未有同样表结构的数据表存在，导致无法进行数据同步
解决：
1、源端获取建表DDL
SET SERVEROUTPUT ON
SET LINESIZE 1000
SET FEEDBACK OFF
set long 999999
SET PAGESIZE 1000
EXECUTE DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'STORAGE',false);

use EMP
go
CREATE TABLE [MVSCHEMA].[EMP_OGG] ( [EMPNO] numeric(4,0), [ENAME] VARCHAR(10), [JOB] VARCHAR(9), [MGR] numeric(4,0), [HIREDATE] DATE, [SAL] numeric(7,2), [COMM] numeric(7,2), [DEPTNO]numeric(2,0), CONSTRAINT "PK_EMPNO_OGG" PRIMARY KEY ([EMPNO])) 6、未指定数据源
源端告警：view report EORA_1
ERROR OGG-00041 Data source not specified.
ERROR OGG-01668 PROCESS ABENDING.
解决：
GGSCI (custom04) 3> EDIT PARAMS EORA_1
添加参数
EXTRACT EORA_1
7、不支持操作，因为“enable_goldengate_replication ”复制未设置为true
源端告警：VIEW REPORT EORA_1
ERROR OGG-02091 Operation not supported because enable_goldengate_replication is not set to true.

8、Oracle重做线程数（2）与检查点线程数（1）不同
源端告警：VIEW REPORT EORA_1

ERROR OGG-01668 PROCESS ABENDING
解决：
GGSCI (custom04) 3> delete extract EORA_1
Deleted EXTRACT EORA_2.

解决：
这个是访问不到asm上的日志 抽取文件要加参数
TRANLOGOPTIONS DBLOGREADER

解决：
是由于PUMP进程参数文件中RMTTRAIL参数投递目标端Trail文件存放路径配置错误重新添加PUMP目标端Trail文件存放路径

修改目标端VAL字段可为NULL即可.

11、目标端数据已存在，唯一约束导致新的insert报错
目标端告警：

解决方法：
参考链接：https://blog.csdn.net/u013820054/article/details/46740687
1.跳过当前事务
2.尝试加入 handlecollisions 参数解决该问题
3.尝试手动修复 target 上的数据
4.尝试加入REPERROR 参数 ignore这个错误
可以忽略掉重复数据的插入而其他类型的报错则abend
REPERROR (DEFAULT, ABEND)
REPERROR (-1, IGNORE)
当前采用的是第四种解决方法：
GGSCI (custom04) 3> edit params repl
添加如下：
REPERROR (DEFAULT, ABEND)
REPERROR (-1, IGNORE)
重启复制进程即可.....
12、SQL Server代理服务未启动
问题：
WARNING OGG-05265 Oracle GoldenGate Capture for SQL Server, EORA.prm: The SQL Agent on server WIN10 is not running. SQL Server CDC requires that the SQL Agent be running to capture change records.
解决
启动SQL Server 代理（MSSQLSERVER）

目标端不存在Delete记录，说明源端该记录并未同步到目标端，并且该表不存在附加日志
解决方法：
1、在参数中添加HANDLECOLLISIONS 当target端缺失delete 、update数据时，target端 自动处理，然后开启
2、停止replicat进程，先将要同步的表mapexclude，然后将在目标端上重新初始化此表，保证源和目标上此表的数据是一致，然后再在replicat进程中将表重新map,启动进程。
网上资料：HANDLECOLLISIONS是我们使用goldengate过程中常有的一个REPLICAT参数，该参数依赖于主键或唯一索引处理冲突数据，常用于初始化阶段。对于无主键或唯一索引的表无法处理冲突，且可能导致重复记录。注意打开此参数则所有数据错误不管reperror如何配置均不再写discard文件，即所有数据冲突信息被默认规则处理，没有任何日志(则会忽略error mapping数据错误，而且不会报告到discard文件)，因此日常复制不建议使用该参数；可予以考虑的特殊场景为只需新增数据，无需复制历史数据。
使用HANDLECOLLISIONS的几个场景：
1、target丢失delete记录(missing delete)，忽略该问题并不记录到discardfile
2、target丢失update记录(missing update)
更新的键值是主键=》 update转换成INSERT ，默认情况下插入记录不完整
更新的键值是非主键=》 忽略该问题并不记录到discardfile
3、重复插入已存在的主键值到target表中，这将被replicat转换为UPDATE现有主键值的行的其他非主键列情景1 target丢失delete记录(missing delete) ：
2018-09-18 17:26:19 ERROR OGG-00551 Database operation failed: Couldn't connect to sqlserver2012. ODBC error: SQLSTATE 37000 native database error 4060. [Microsoft][ODBC SQL Server Driver][SQL Server]无法打开登录所请求的数据库 "mark"。-登录失败。
这种错误提示非常的坑，不能按照字面意思去解决这个问题，无论修改odbc里面dsn的登陆还是sqlserver里面的授权都没用，而实际上在GGSCI里面同样的操作是没有问题的。
而解决这个问题的方法很简单：
打开Microsoft SQL Server Management Studio，在安全性->登录名->选择NT AUTHORITY/SYSTEM->右键->属性->服务器角色->勾选sysadmin就可以了
产生这个问题的原因在于GoldenGate的 manager(mgr)服务是以服务的方式运行的，在windows下是SYSTEM账户运行的，而SYSTEM账户可能没有权限访问Sql server数据库
另外一个是我们一般安装Sql server都选的混合模式，所以建立ODBC连接都是使用的集成账户登录

这是因为目标端mgr进程未开启，开启目标端mgr进程，并重启源端mgr进程
