晚上接到电话，客户的一套核心Oracle RAC数据库连接不上，连接时报无监听程序，客户的Oracle RAC版本为11.1.0.6，平台为AIX 6.1.05，使用了IBM HACMP 5.5.0.8。 当我远程过去的时候，发现节点2已经没有任何oracle用户的进程，且concurrent的vg没有激活，HACMP的服务也offline。 另一个节点Oracle的实例是正常的，且有部分服务器进程依然在工作，但是本地监听器出现了故障，导致新的连接无法连接到实例，通过crs_stat -t看到两个实例的监听也都是OFFLINE状态。 在节点上并没有发现有LISTENER进程，且手动杀掉了所有的服务器进程，在oracle用户下启动监听时收到以下的报错： $ lsnrctl start listener_cdfy740a LSNRCTL for IBM/AIX RISC System/6000: Version 11.1.0.6.0 - Production on 20-NOV-2014 20:09:09 Copyright (c) 1991， 2007， Oracle.
