ORA-29937: 域索引无法被系统管理

它是由于一个索引维护错误，导致无法创建或管理索引对象。

官方解释

ORA-29937: domain index cannot be system-managed

Cause: A system-managed index could not be created or managed on the specified object.

Action: First, execute DROP INDEX to drop the index, if one exists. Then grant proper privileges to the owner of the index, if it is to be system-managed.

常见案例

ORA-29937: domain index不能被系统管理，出现这个问题的常见情况是由于要创建的域索引不是属于系统表的，但是用户没有权限创建新索引。

一般处理方法及步骤

1、检查要创建索引所属对象是否是系统表，如果是，则切换到sys用户，则可以创建索引：create index ON sys.table ()。

2、检查是否给要创建索引的表拥有权限：给要创建索引的表授予create index权限：grant create index to

3、如果仍然是ORA-29937，则可能需要检查一下有没有其他存在的index，如果有可能是其他index被加到表上，导致无法创建新的index：drop index ；这样就可以删除存在的index，然后再次尝试创建新的index。
