ORA-15412: 操作在磁盘组string 上不兼容在appliance模式下。
这个错误出现是因为,在Oracle ASM(应用程序与服务器管理器)中,存在不兼容的操作发生在磁盘组上,而要求这些操作在Oracle ASM Appliance模式下完成。
Oracle ASM Appliance模式是由CRS配置的Oracle ASM实例组成,该实例维护和管理所有Oracle数据库及其文件。
常见案例
1)尝试在具有实例的磁盘组上运行操作,该操作在Oracle ASM Appliance模式下不受支持。
2)尝试使用实例来创建或管理磁盘组,而此操作在Oracle ASM Appliance模式下不受支持。
一般处理方法及步骤
1)确认所有操作均在Oracle ASM Appliance模式下执行;
2)检查日志以定位冲突;
3)从Oracle ASM中删除磁盘组;
4)访问在磁盘组上执行的其他操作,比如更改磁盘组设置;
5)确保所有操作在Oracle ASM Appliance模式下完成;
6)重新创建磁盘组;
7)确保所有操作在Oracle ASM Appliance模式下完成;
8)如果仍然遇到错误,尝试使用srvctl命令更改磁盘组的状态。
