Node 'rac2' configured role is 'hub'
这里实现了ORACLE 12C RAC的leaf和hub 角色相互转换,在转换的过程中需要转移确认集群和ASM均为flex mode,如果参考相关文档完成转换
ORACLE 12C RAC修改ocr/votedisk/asm spfile所在磁盘组名称
今天看着我这个单节点的12C rac,突然觉得ocr所在的磁盘组叫做+DG_SYS有点不舒服，想改成+SYS_DG。处理方法是先把ocr/votedisk/asm spfile迁移到已经存在的asm中,然后修改磁盘组名称,最后迁移到新名称磁盘组中(本次处理流程+DG_SYS—>+DATA—>+SYS_DG)

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
验证+DG_SYS磁盘组未被使用

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
