这里证明create asm spfile会自动修改spfile在gpnptool对应的profile里面的配置,无需人工干预

重启crs
为了使得asm使用新的磁盘组中的spfile文件

[root@xifenfei ~]# crsctl stop crs
[root@xifenfei ~]# crsctl start crs

至此ocr/votedisk/asm spfile所在磁盘组修改名称完成,因为该库是一个单节点的rac,如果是两个或者更多节点的rac可以实现不停机的情况下进行(分步重启节点).该处理过程和11.2 rac完全相同,未有任何的改变

  • ORACLE 12C RAC hub AND leaf 相互转换
  • oracle 12.1 RAC的ocr磁盘组异常恢复
  • OCR/Vote disk 维护操作
  • 安装 ORACLE 12C 单节点RAC
  • has a disk HB, but no network HB—-traceroute不通导致
  • crfclust.bdb文件过大处理
  • 公有云安装19c rac遇到问题—169网段udp异常
  • oracle rac 12.2 执行root.sh报CLSRSC-400
  • 修改11.2 RAC 的 SCAN IP
  • 一次 CRS-1013: ASM 磁盘组中的 OCR 位置不可访问 故障分析
  • RAC维护命令
  • 因asm sga_target设置不当导致11gr2 rac无法正常启动

此条目发表在ORACLE 12C,Oracle RAC分类目录，贴了ORACLE 12C,oracle rac标签。将固定链接加入收藏夹。
