1. 生产环境注意调整以下参数：
  1. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
  1. + 1.节点间滚动添加UDEV磁盘
  1. + 2.ASM 内存大小
  1. + 3.POWER_LIMIT别弄太大
  1. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

  1. 实验环境
  1. --系统环境:Centos 6.10
  1. --数据库：Oracle 11g RAC
  1. --磁盘绑定：udev
  1.  
  1. 实验目的
  1. --存储空间不足，需要给磁盘组DATA加一块磁盘
  1.  
  1.  
  1. 准备工作
  1.     1.检查各个节点database、asm及grid日志是否有错误信息
  1.  
  1.  
  1.     2.检查各个节点服务状态(切换到grid用户)
  1.       --列出数据库名
  1.         [grid@node2 ~]$ srvctl config database 
  1.         RacNode
  1.         [grid@node2 ~]$
