适用于

  • 适用于 Oracle ( SCO ) 4.x 的 SnapCenter 插件
  • Oracle Real Application Cluster ( RAC )

问题

在 SnapCenter 中注册的每个基于 Oracle RAC 的数据库(即使在 RAConeNode 配置中也是如此)都是指主机组,而不是单个主机引用。
要使主机处于维护 [1] 状态,可以选择首选主机,以便在主机脱机或正在维护时进行备份。
 
但是,如果通过将多节点 RAC 数据库更改为 RACONENode 数据库而使主机组最终只包含一个主机条目,并且首选主机列表仅包含一个节点,则在初始发现期间会为正确的主机选择 nolonger ,并且备份失败:

ERROR: Job Failed:

Preferred hosts are not found or could be in maintenance mode. Configure preferences for resource
