1、执行job验证同步情况

查看结果，显示BONUS与SALGRADE在两节点同步不成功，如下图：

2、查看report报告，发现如下：

Table has no keys defined.    --预判错误因为缺少主键约束

Comparison terminated with errors.

3、为BONUS与SALGRADE添加主键

SQL>select CONSTRAINT_NAME,INDEX_NAME,TABLE_NAME fromuser_constraints;

--检查约束，BONUS与SALGRADE未发现添加主键信息

CONSTRAINT_NAME                INDEX_NAME                     TABLE_NAME

------------------------------------------------- ------------------------------

FK_DEPTNO                                                     EMP

PK_DEPT                        PK_DEPT                        DEPT

PK_EMP                         PK_EMP                         EMP

SYS_C002941                    SYS_C002941                    TCUSTMER

SYS_C002942                    SYS_C002942                    TCUSTORD

SQL>alter table BONUS add constraint PK_ename primarykey(ename);    --为BONUS添加主键

Table altered.

SQL>alter table SALGRADE add constraint PK_GRADE primarykey(grade); --为SALGRADE添加主键

Table altered.

4、执行job验证同步情况

如下图可知，同步检验成功：
