使用 crsctl check cluster 可快速確認叢集核心服務是否正常運行：
[grid@rac02 ~]$ crsctl check cluster CRS-4537: Cluster Ready Services is online CRS-4529: Cluster Synchronization Services is online CRS-4533: Event Manager is online
[grid@rac02 ~]$ srvctl status database -d racdb Instance racdb1 is running on node rac01 Instance racdb2 is running on node rac02
[grid@rac02 ~]$ srvctl status instance -d racdb -i racdb1 Instance racdb1 is running on node rac01
檢查 VIP、網路、GSD、ONS、eONS 等節點級資源：
