关于DB2 HADR就不做多的解释了，和oracle的DataGuard类似
这里记录一下平时实验的一个快速部署手册
CentOS6.5 x64位

192.168.122.102 kvm111
目录准备

安装db2-略
创建测试库
db2 create db hadb01
下面新增一些数据，只在主库添加：
db2 connect to hadb01
db2 "create table t1(id int)"
db2 "insert into t1 values(1)"
db2 "insert into t1 values(2)"
db2 "create table t2(id int)"
db2 "insert into t2 values(1)"
db2 "insert into t2 values(2)"
开启归档模式
主库和备库都操作
先修改归档参数，做离线备份，重启数据库后，手工测试归档

standby端的数据库通过primary端的数据库恢复来,恢复后必须是roll forward-pending状态，restore中不能使用without rolling forward，启动备库之前先确定这个状态
