Afrer adding  the followings in rac 2 nodes of $grid_home/network/admin/sqlnet.ora:

TCP.INVITED_NODES=(10.0.6.176,10.0.6.178,192.168.168.100,10.0.6.177,10.0.6.179,192.168.168.101,10.0.6.180,10.0.1.237,10.0.2.50,10.0.6.73,10.0.6.155,10.0.6.156,10.0.6.157,10.0.6.158,10.0.6.159,10.0.6.126)

TCP.VALIDNODE_CHECKING=yes

restart listener and apply white list;(INVITED_NODES includes vip,public ip,privite ip,scan ip of rac)

and remote host in INVITED_NODES:10.0.6.126 can connect rac 2 nodes via tnsnames.ora,but cannot connect scan_ip via tnsnames.ora,and tnsping also report error ,cannot connect ORA-12547: TNS:lost contact

what reason?

Howdy, Stranger!
