Oracle HA双机主备基于共享存储模式并利用keepalived管理实现高可用
HA概述HA(High Available)即由两台计算机组成并对外提供一组相同的服务，也叫做一主一备模式。正常情况下由主服务器提供服务，备服务器处于待机备用，备机可以随时接替主服务器的工作。也就是当主服务器宕机或所提供的服务不可用时，备用服务器会主动激活并且替换主服务器继续提供服务，这时主服务器上的服务资源包括网络(IP)、存储、服务(Web/数据库)就会转移到备机接管，从而提供不间断的服务。基于此，便可以将服务器的宕机时间减少到最低，对业务实现不中断或短暂中断。
由一组计算机(多台)组成一个整体并向用户提供相同的网络资源或服务，这种模式叫做HA集群(High Available Cluster)。
Oracle HA
Oracle HA高可用，又叫做双机热备，一般用于关键性业务。
Oracle双机热备模式
常用的有Data Guard、RAC(Real Application Clusters)、基于HA软件实现的双机热备。
作用和区别
lData Guard采用重做日志复制技术，对主业务数据进行实时的异步同步备份，有一主一备、一主多备模式，一般常用于容灾(异地备份、灾难恢复)；存储独立、数据完整备份；备机可以做数据分析、报表统计等；主备自由切换，能实现自动快速故障转移；备用角色强制转换为主用角色会破环Data Guard架构；设计复杂、维护难度大
lRAC多个实例同时运行，无主备概念，有集群负载功能，其中某一台down机，不影响整体服务，不存在故障切换时间，可以提供高性能服务；存储共享，由ASM管理存储；硬件成本低；设计简单、维护难度大
lHA双机热备可以提供高可用性，保证业务的持续稳定运行，可以实现自动快速故障转移，存在短暂的切换时间(10-30s)。一般用于关键性业务；存储共享；有商业的HA方案，也可以使用开源的高可用软件keepalved、heartbeat搭建实现HA方案；设计复杂、维护难度小

Oracle软件安装步骤
1、 同时在主备上安装Oracle数据库软件，数据库的安装目录和环境变量保持一致
2、 仅在主服务器上建立数据库实例(主服务器上挂载共享存储并使用DBCA新建库)
3、 主服务创建数据库实例后，将主库上的控制文件、参数文件(SPFILE)、以及密码文件传输到备用服务器上相应的目录
l备用服务器DB2
##创建对应的数据库文件目录
# su - oracle
$ mkdir /u01/app/oracle/admin/HMODB
$ mkdir /u01/app/oracle/admin/HMODB/{adump,dpdump,pfile}
$ mkdir /u01/app/oracle/flash_recovery_area/HMODB
##密码文件
$ scp oracle@hmdg-db1:/u01/app/oracle/product/11.2.0/db_1/dbs/orapwHMODB /u01/app/oracle/product/11.2.0/db_1/dbs/orapwHMODB
##SPFILE参数文件
$ scp oracle@hmdg-db1:/u01/app/oracle/product/11.2.0/db_1/dbs/spfileHMODB.ora /u01/app/oracle/product/11.2.0/db_1/dbs/spfileHMODB.ora
##控制文件，仅需要将位于非共享存储的数据目录下的控制文件传输到其他磁盘或目录位置下
$ scp oracle@hmdg-db1:/u01/app/oracle/flash_recovery_area/HMODB/control02.ctl /u01/app/oracle/flash_recovery_area/HMODB/control02.ctl
$cp /u01/app/oracle/flash_recovery_area/HMODB/control02.ctl /home/oracle/rman/HMODB/control03.ctl在备用服务器上启动数据库
1、 主服务器上关闭数据库实例
2、 主服务器上卸载共享存储
3、 备服务器上挂载共享存储
4、 备服务器上启动监听
5、 备服务器上启动数据库实例
注意：不要同时挂载共享存储启动数据库实例，否则会导致数据不一致

##关闭数据库监听

##挂载/dev/sdb1共享存储到/oradta下
# mount /dev/sdb1 /oradata/
##启动数据库监听

$ export ORACLE_SID=HMODB

READ WRITE HMODB PRIMARY再次手动切换步骤
由于安装数据库实例时，创建了多个控制文件，并且这些控制文件都保存在不同的磁盘上，在主备进行切换的时，位于非共享存储的控制文件需要手动进行同步。这是由于在关闭数据库实例时Oracle同时将当前数据库状态信息记录到控制文件中，在没有启动数据库实例的备机就无法同步自身的其他的控制文件。这时就需要使用共享存储里的控制文件进行恢复。
1、 在DB2关闭正在运行数据库实例
##DB2:
$ sqlplus / as sysdba
SQL> shutdown immediate
# umount /oradata/ 2、在DB1上进行恢复启动数据库实例
##DB1：
# mount /dev/sdb1 /oradata/
$ export ORACLE_SID=HMODB
$ sqlpus / as sysdba
SQL> startup nomount
SQL> alter database mount;
SQL> alter database open;
如果控制文件在不同的磁盘目录，那么就需要执行这一步恢复控制文件
$ rman target /
RMAN> restore controlfile from '/oradata/HMODB/control01.ctl'; 启动数据库监听
$ lsnrctl start
或者直接只有操作系统的cp、scp等命令进行拷贝恢复
$ cp /oradata/HMODB/control01.ctl /u01/app/oracle/flash_recovery_area/HMODB/control02.ctl
SQL> SELECT NAME,OPEN_MODE,NAME,DATABASE_ROLE FROM V$DATABASE;
NAME OPEN_MODE NAMEDATABASE_ROLE
--------- -------------------- --------- ----------------
HMODB READ WRITE HMODB PRIMARY主备服务SSH密钥配置
配置oracle用户的ssh密钥，用于主备通过oracle身份自动检测对方的数据共享存储状态。在keepalived脚本管理中自动检查对方的挂载状态，并在主备切换的过程中，待接管的服务器等待对方umount共享存储之后，正常启动数据库实例。（如果主服务异常关机或网络中断，不需要等待对方umount存储，主服务器异常关机时keepalived会即时检测到并自动切换到备机上）
$ ssh-keygen -t rsa -b 2048
$ ssh-copy-id -i ~/.ssh/id_rsa.pub oracle@hmdg-db2
$ ssh-keygen -t rsa -b 2048
$ ssh-copy-id -i ~/.ssh/id_rsa.pub oracle@hmdg-db1 添加主备防火墙互通规则

4、启动数据库到nomount状态，并恢复控制文件
5、启动数据库实例到open状态
6、启动数据库监听，切换完成
注意：如果使用系统命令手动切换，应该要保证正在运行oracle服务的主节点先正常关闭，并且卸载共享存储之后，再启动备用节点的oracle服务(即不能同时挂载共享存储)
