- 启动RAC
手工启动按照HAS, cluster, database的顺序启动，具体命令如下：
- 启动HAS(High Availability Services)，必须以root用户
[root@orcl-1 ~]# crsctl start has
CRS-4124: Oracle High Availability Services startup failed.
CRS-4000: Command Start failed, or completed with errors.
报错原因是因为11g的一个bug，重新开一个窗口执行/bin/dd if=/var/tmp/.oracle/npohasd f=/dev/null bs=1024 count=1
[root@orcl-1 ~]# crsctl start has
CRS-4640: Oracle High Availability Services is already active
CRS-4000: Command Start failed, or completed with errors.
以上has启动命令需要在每个节点分别执行
- 启动集群（cluster）
[root@orcl-1 ~]# crsctl start cluster -all --所有节点同时启动
CRS-5702: Resource 'ora.evmd' is already running on 'orcl-1'
CRS-5702: Resource 'ora.crsd' is already running on 'orcl-1'
或者只启动指定节点的
[root@orcl-1 ~]# ./crsctl start cluster -n orcl1 orcl2 --两个节点同时启动
- 启动数据库,oracl用户执行srvctl命令（假设数据库名为ORCL）：
[root@orcl-1 ~]# srvctl start database -d orcl ---启动所有节点上的实例
PRCC-1014 : orcl was already running
或者每个节点登录数据库后再执行
SQL>startup
[root@orcl-1 ~]# srvctl status asm ---查看ASM状态
ASM is running on orcl-1,orcl-2
[root@orcl-1 ~]# crs_stat -t -v ---查看集群资源状态（oc4j、gsd默认服务是禁用的）
