ORA-01883: overlap was disabled during a region transition ORACLE 报错 故障修复 远程处理

文档解释

ORA-01883: overlap was disabled during a region transition

Cause: The region was changing state and the overlap flag was disabled.

Action: Please contact Oracle Customer Support.

ORA-01883错误指示覆盖(overlap)在高可用性数据库(RAC)的数据库域之间的转换时被禁用。

这意味着在将一个数据库域归还到RAC集群中运行时,尝试在另一个数据库域上发出的请求将被抑制,直到将数据库域归还到RAC集群中运行。

官方解释

ORA-01883错误指示RAC集群中的域之间的转换时,禁用了覆盖(overlap)。这意味着,除非域重新加入RAC集群,否则在重新加入RAC集群之前,所有请求都将被抑制。

常见案例

这种情况通常发生在数据库域管理员(DBA)在RAC集群中关机或重新启动数据库域时出现。此时,RAC会阻止这个域访问其他数据库域,以使数据库保持一致性,并且该域被视为失败的。

正常处理方法及步骤

如果计算机重新加入RAC集群,那么在重新加入RAC集群之前,所有请求都将被抑制。一旦数据库域被重新归还RAC集群,就可以重新启用覆盖(overlap),并且以前被抑制的请求也将被处理。
