[Oracle19C ASM管理] ASM服务的启停
自动方式启停
crsctl stat res -t 查看ASM服务的状态，it's ok that ora.ons和ora.diskmon是OFFLINE

停止ASM服务
crsctl stop has
has = High Availability Service
[grid@centos7-19c.localdomain:/home/grid]$crsctl stop has
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'centos7-19c'

CRS-2793: Shutdown of Oracle High Availability Services-managed resources on 'centos7-19c' has completed
CRS-4133: Oracle High Availability Services has been stopped.
开启ASM服务
crsctl start has
[grid@centos7-19c.localdomain:/home/grid]$crsctl start has
CRS-4123: Oracle High Availability Services has been started.
手动方式启停ASM
grid用户下关闭监听，因为监听只是运行在grid用户，和oracle用户没有关系
lsnrctl stop
[grid@centos7-19c.localdomain:/home/grid]$lsnrctl stop

这时查看crsctl stat res -t , 可以看到listener已经OFFLINE。

--------------------------------------------------------------------------------
进入Oracle用户停止数据库
[oracle@centos7-19c.localdomain:/home/oracle]$sqlplus / as sysdba
SQL*Plus: Release 19.0.0.0.0 - Production on Mon Feb 13 21:08:28 2023

切换回grid用户，可以看到数据库已经停止
[grid@centos7-19c.localdomain:/home/grid]$crsctl stat res -t

在grid用户下， 使用sqlplus / as sysasm 链接， 使用shutdown immediate关闭ASM服务
[grid@centos7-19c.localdomain:/home/grid]$sqlplus / as sysasm
SQL*Plus: Release 19.0.0.0.0 - Production on Mon Feb 13 21:11:55 2023

SQL> shutdown immediate;

ASM instance shutdown
目前只剩ora.cssd， ora.evmd是开启状态的。使用crsctl stop has关闭他们
[grid@centos7-19c.localdomain:/home/grid]$crsctl stop has
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'centos7-19c'
CRS-2673: Attempting to stop 'ora.evmd' on 'centos7-19c'
CRS-2677: Stop of 'ora.evmd' on 'centos7-19c' succeeded
CRS-2673: Attempting to stop 'ora.cssd' on 'centos7-19c'

CRS-2793: Shutdown of Oracle High Availability Services-managed resources on 'centos7-19c' has completed
CRS-4133: Oracle High Availability Services has been stopped.
手工启动ASM
手工关闭ASM后，grid用户使用crsctl start has 启动。
[grid@centos7-19c.localdomain:/home/grid]$crsctl start has
CRS-4123: Oracle High Availability Services has been started.
切换到oracle用户启动数据库服务，
[grid@centos7-19c.localdomain:/home/grid]$su - oracle

然后切回grid，crsctl stat res -t 可以看到所有服务都已启动。
