Oracle RAC Database 11.1.0.6监听故障案例


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

10.107.64.1是该节点的vip地址，下面是RAC环境的hosts配置：

10.107.64.1    vip1
10.107.64.2    vip2
10.107.64.3    cdfy740a
10.107.64.4    cdfy740b
172.201.201.1  prv1
172.201.201.2  prv2

手动停掉该节点的nodeapps服务：

cdfy740a@root[/oracle/app/11.1.0/crs/bin]./srvctl stop nodeapps -n cdfy740a

成功停止后，VIP在主机层面已经消失：

之前使用lsnrctl status listener_cdfy740a查看监听器状态时也收到Connection refused的错误。

查看主机层面已经成功绑定了VIP地址：

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。
