再次尝试手动启动本地监听器：
cdfy740a@root[/]su - oracle
$ lsnrctl start listener_cdfy740a

启动依然失败。
检查监听器配置文件：
$ cat listener.ora
# listener.ora.cdfy740a Network Configuration File: /oracle/app/oracle/product/11.1.0/db_1/network/admin/listener.ora.cdfy740a
# Generated by Oracle configuration tools.
LISTENER_CDFY740A =
? (DESCRIPTION_LIST =
? ? (DESCRIPTION =
? ? ? (ADDRESS = (PROTOCOL = TCP)(HOST = vip1)(PORT = 1521))
? ? ? (ADDRESS = (PROTOCOL = TCP)(HOST = 10.107.64.1)(PORT = 1521)(IP = FIRST))
? ? ? (ADDRESS = (PROTOCOL = TCP)(HOST = 10.107.64.3)(PORT = 1521)(IP = FIRST))
? ? )
? )
在监听配置文件中，vip1和10.107.64.1是两个重复的地址，手动将10.107.64.1所在行去掉之后，监听即可正常的??动。
之后恢复节点2的HACMP服务，Oracle RAC随即恢复正常。
另外，还发现客户的监听日志已经被填得很大，大概在1.6GB左右，过大的监听日志文件也会导致监听器不稳定，这里将两个节点的监听日志进行了重命名操作。
