解决goldengate复制进程应用缓慢一例

前段时间配置的oracle10g-->11g的gg，到目前为止应用都还正常，没什么问题，今天测试了下大批量更新的应用情况,具体操作如下：
源库：
create table m_order_test5 as select * from m_order_info where 1=2;
insert into m_order_test5 select * from m_order_info;
commit;
m_order_info 表主键、约束都有，新建的表m_order_test5没有任何主键和约束，实验到此，主库和目标库同步都没什么问题，然后就是大批量的更新操作：
update m_order_test5 set link_name='mordertest5';
commit;
之后到目标观察发现一直没有应用过去，相关日志如下：

这里用到了oracle的隐藏参数作为提示，具体产生原因主要是这张新建的表没有任何主键和约束，oracle默认是all column作为key来处理的，并且在目标库也没有最新的statistics，所以oracle自己在处理这样的表的时候就加上了这个隐藏参数提示，最直接的后果就是全表扫描，逻辑读非常高：
具体解决办法如下：
在目标库停掉replicate进程，操作系统里简单的stop命令是停不下来的，我的做法是，在数据库里查询到相应的操作系统进程编号，然后kill掉：
GGSCI (trptdb) 34> info all
Program Status Group Lag at Chkpt Time Since Chkpt
MANAGER RUNNING
REPLICAT ABENDED REP1 00:00:00 00:51:39
然后在目标库m_order_test5表上增加了一个主键：
alter table M_ORDER_TEST5 add constraint M_ORDER_TEST5_pk primary key (order_id);
alter table M_ORDER_TEST5 enable primary key ;
收集下统计资料：
SQL> exec dbms_stats.gather_table_stats('mynet_app','M_ORDER_TEST5');

PL/SQL procedure successfully completed
最后启动replicate进程，又开始欢快的跑起来了：

sda 1.00 0.00 8.00 0 8

最后后续的dml操作也一并应用完毕了。最后提醒大家一下，对于gg来说，最好不要使用create table a as select * from b这样的ddl语句来创建表，会导致2端数据不一致！
记录一下~
