After the invalid record is removed, runcluvfy checks and continues to install everything normally through. OUI.
It is because of invalid records in/etc/hosts that the RAC Installation check fails. remind you to install the RAC file carefully.

  • 10g rac Installation notes
  • When localhost. localdomain is missing in hosts, the listener startup time is too long.
  • A single Nic is bound with multiple IP addresses, leading to errors such as TNS-12542
  • IP = FIRST
  • Use PXE to brush XD
