Oracle 19C RAC停止：
一般Oracle 19C RAC管理的工具分成：对Oracle 实例管理的是srvctl和对集群管理的crsctl工具。
Oracle 19C RAC的关闭：
1.使用oracle用户（在Oracle 19C RAC集群的其中一个节点操作）：
[oracle@rac01 19.3.0]$ cd /u01/app/oracle/product/19.3.0/db_1/bin/
[oracle@rac01 bin]$ ./srvctl stop database -d cxmtdb
[root@rac01 ~]# /u01/app/19.3.0/grid/bin/crsctl stop crs

2.crsctl验证
[root@rac01 ~]# /u01/app/19.3.0/grid/bin/crsctl stat res -t
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4000: Command Status failed, or completed with errors.
[root@rac02 /]# /u01/app/19.3.0/grid/bin/crsctl stat res -t
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4000: Command Status failed, or completed with errors.
3.使用root用户关闭操作系统（在Oracle 19C RAC集群中的2个节点都需要做操作）：
[root@rac01 /]# init 0
[root@rac02 /]# init 0
4.关闭共享存储
二 Oracle 19C RAC的启动：
1.启动共享存储的操作系统
2.打开操作系统（在Oracle 19C RAC集群中的2个节点都需要做操作）
3.使用root用户（在Oracle 19C RAC集群中的2个节点都需要做操作）：
[root@rac01 ~]# /u01/app/19.3.0/grid/bin/crsctl start crs
[root@rac02 ~]# /u01/app/19.3.0/grid/bin/crsctl start crs
查看集群服务的启动状态：
[root@rac01 ~]# /u01/app/19.3.0/grid/bin/crsctl stat res -t
[root@rac02 ~]# /u01/app/19.3.0/grid/bin/crsctl stat res -t
4.使用oracle用户（在Oracle 19C RAC集群的其中一个节点操作）：
[root@rac01 ~]# su - oracle
[oracle@rac01 ~]$ /u01/app/oracle/product/19.3.0/db_1/bin/srvctl start database -d cxmtdb
5.使用Oracle用户进行登录测试：
[oracle@rac01 ~]$ sqlplus / as sysdba
