RAC: Real Application Cluster (Real Application Cluster) is widely used. As an Oracle Database Cluster Environment, RAC has a complete set of management knowledge. Here I will demonstrate the restart process of rac.

1. Check the node information and running status before restarting.
You can use srvctl status database-d database name // to view node Information
Crs_stat // view node status
The data node is composed of two instances and runs on different nodes. The status is OK.
2. First shut down the database
Srvctl stop database-d database name
3. Close the connected nodes respectively.
Log on to the corresponding server, and enter the following command to close the node.
Srvctl stop nodeapps-n Node 1/node 2
4. Restart the database
After some data operations are completed, enable the database by using the srvctl start database-d database name.
Under normal circumstances, each node will automatically get up. Let's check if it doesn't get up automatically and we will restart it manually.
Crs_stat-t view status
