oracle11.2.0.4 rac asm启动故障

Posted 2020-11-03

现场人员反映一套库启动失败，集群资源启动失败，发截图和日志过来分析

分析日志后发现： ASM没有启动 OCR等不能启动

问题1：

第二个报错提示： 大概心跳网络有问题

问题2：

ping验证私有网络没有问题

问题1很明显，Oracle rac asm方式，OCR存放在asm里面，启动之前确保asm实例启动

由于服务器重启后没把asm实例带起来。我们必须手工启动asm实例

sqlplus /? sysasm startup 启动asm实例后我们启动集群相关资源 [[email protected] ~]# crsctl start has [[email protected] ~]# crsctl start crs [[email protected] ~]# crsctl check crs CRS-4638: Oracle High Availability Services is online CRS-4537: Cluster Ready Services is online CRS-4529: Cluster Synchronization Services is online CRS-4533: Event Manager is online 启动实例资源等 crsctl start cluster –all

验证登陆节点1登陆正常

总结：现场人员rac启动顺序不熟悉，Oracle grid root用户命令混用
