Establish Oracle11g RAC in linux (2)

1. Test IP address occupation configured for the network before installation

Go to windows, run cmd, and run the ping command to verify whether the network segment is occupied.

Note: You can use any CIDR block. Make sure that the CIDR block is not occupied by other devices.
