本文主要是介绍oracle exadata x8-2 crs有报错PRVG-12885，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

PRVG-12885

处理办法：

Output from

        # dcli -l root -g dbs_group ip addr list | grep ib

shows that all MTU sizes are 65520

Output from

        #  ifconfig -a

shows that the MTU size for the loopback interface was 16436

临时办法：

Set the mtu size of loopback to 65520 on each of the RAC nodes
#ifconfig lo mtu 65520

参考：

RAC addnode.sh gives PRVG-12885 error when MTU size of 65520 is involved (Doc ID 2091782.1)

PRVG-12885 : ICMP packet of MTU size "65520" does not go through subnet (Doc ID 2165823.1)
