心跳长时间missing，导致2节点被驱逐当发现一个集群其中一个节点宕机，比如+ASM2在集群里offline，immediate，要重新拉起来所要做的步骤一、停干净当前宕机节点集群/oragrid/app/11.2.0/grid/bin/crsctl stop crs -f 二、ps -ef |grep d.bin ----查看集群是否停干净，grep d.bin是因为有很多集群资源都是这个结尾的，例如 ohasd.bin,mdns... 阅读详情

AI摘要

国庆巡检时发现Oracle 11g RAC数据库alert日志有异常重启信息。通过分析数据库告警日志、crs及ocssd日志、节点2系统日志，发现节点之间心跳通信异常致节点2重启。经查询，此为11.2.0.3版本的bug，当前生产环境版本11.2.0.4受影响，需打对应补丁修复。

一、背景

在国庆期间巡检的时候，发现数据库alert日志中出现了异常重启的信息，当即对该报错进行分析处理。

二、处理过程

（1）数据库告警日志分析

通过crs日志可以看出，在14:50:31开始出现节点之间通信失败报错，随后节点2发生了重启。

（3）查看节点2系统日志

节点2系统日志：

系统日志无异常报错。

三、故障原因分析

根据日志信息可以看到，是由于节点之间心跳通信异常，导致节点2发生了重启，根据日志中的关键信息：

2024-10-05 14:50:45.484:
[cssd(10595)]CRS-1607:Node nxybj2 is being evicted in cluster incarnation 587229053; details at (:CSSNM00007:) in /u01/app/11.2.0/grid/log/nxybj1/cssd/ocssd.log.
2024-10-05 14:50:47.994:
[cssd(10595)]CRS-1625:Node nxybj2, number 2, was manually shut down

在mos上查询该报错，通过查询到的结果分析，该报错为bug：
