这是一个CSDN Oracle开发版块里，网友问过的一道题
题如下
create table A_TEST
(
PAYOUT_ITEM_CODE VARCHAR2(30) not
null,
FORMULA_DET VARCHAR2(1000)
)
create table B_TEST
(
ELEMENT_ID VARCHAR2(5) not null,
NAME VARCHAR2(41)
)
求写oracle多个字符替换（有测试数据）

如果我们的SQL Server要保证高可用性，那么可以采用故障转移群集。最简单的故障转移群集是两台服务器，一台做活动的服务器，另一台做备用服务器，这就是AP模式的Cluster。另外一个模式就是AA模式，也就是两台服务器都是运行SQL Server实例。
SQL Server不像Oracle一样有RAC，所以不可能说两台服务器同时运行同一个实例，想 ......
