+ORCL_DATA1/orcl/d启动节点应用程序后，启动 ASM 实例。最后，启动 Oracle 实例（和相关服务）以及企业管理器数据库控制台。
$ export ORACLE_SID=orcl1
$ srvctl start nodeapps -n rac1
$ srvctl start asm -n rac1
$ srvctl start instance -d orcl -i orcl1
$ emctl start dbconsole
 
使用 SRVCTL 启动/停止所有实例
启动/停止所有实例及其启用的服务。我只是觉得有意思就把此步骤作为关闭所有实例的一种方法加进来了！
$ srvctl start database -d orcl
$ srvctl stop database -d orcl
 
 
启停止监听
hostb$lsnrctl start listener_hostb
hostb$lsnrctl stop listener_hostb备份votning diskdd if=voting_disk_name of=backup_file_name
