common problem
1. Safe shutdown sequence
- Overall cluster shutdown
# 关闭数据库实例
srvctl stop database -d racdb
srvctl status database -d racdb
# 关闭Grid群集
/u01/app/12.2.0/grid/bin/crsctl stop cluster -all
- A node of the cluster is down
# 关闭数据库实例
srvctl stop database -d racdb -i racnode01
srvctl status database -d racdb -i racnode01
# 关闭Grid群集
/u01/app/12.2.0/grid/bin/crsctl stop cluster
2. Oracle RAC prohibits automatic startup
# crs软件关闭自动启动
crsctl disable crs
# 关闭数据库的自动启动
srvctl disable database -d racdb
