原因：
metalink說(shuō)明：Client is able to resolve all Fully Qualified Domain Name (FQDN) SCAN and VIP name but not short ones(without domain name) as its in different domain;

even though FQDN names were specified during Grid Infrastructure setup, due to bug 9150053 by default DBCA set database parameter local_listener to short node VIP name

while database is created.
因此只要把數(shù)據(jù)庫(kù)實(shí)例參數(shù)local_listener內(nèi)的host改為vip的IP地址即可

解決辦法：
rac1:
SQL> show parameter local_listener

NAME                     TYPE     VALUE
------------------------------------ ----------- ------------------------------
local_listener                 string     (DESCRIPTION=(ADDRESS_LIST=(AD
                         DRESS=(PROTOCOL=TCP)(HOST=rac1
                         -vip)(PORT=1521))))
SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.2.111)(PORT=1521))))' scope=both sid='orcl1';
SQL> alter system register;

rac2:
SQL> show parameter local_listener

NAME                     TYPE     VALUE
------------------------------------ ----------- ------------------------------
local_listener                 string     (DESCRIPTION=(ADDRESS_LIST=(AD
                         DRESS=(PROTOCOL=TCP)(HOST=rac2
                         -vip)(PORT=1521))))
SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.2.112)(PORT=1521))))' scope=both sid='orcl2';
SQL> alter system register;
