ORA-28015: Account unlock attempted on read-only database but a conflicting account lockout on the primary exists
Cause: An attempt to unlock an account on a read-only database was prevented, because the account was previously marked as locked on the primary database. All attempts to unlock the account on the read-only database will be prevented as long as the overriding “account locked” condition exists at the primary database.
Action: If this database is part of a Data Guard configuration, perform the account unlock action on the primary database. If this database is read-only, then set the database to read/write and perform the account unlock action.
ORA-28015说明在尝试解锁只读数据库上的账户时发生了冲突,因为主数据库上存在着另一个已锁定的账户。
当在更新数据库文件时,您可能会遇到 ORA-28015 错误。它表示,您正在尝试解锁只读数据库上的账户,但在主数据库上存在着另一个已锁定的账户,因此不能完成解锁。这通常是由于主数据库和只读数据库使用相同的用户ID所引起的。
以下是最常见的导致 ORA-28015 错误的实例:
1. 您在主数据库上创建了账户 A,并将其添加到只读数据库,但尚未解锁此账户。
2. 您登录到只读数据库,尝试解锁账户 A,但该账户在主数据库上仍处于锁定状态,因此 ORA-28015 错误发生。
如果您遇到了 ORA-28015 错误,您可以通过以下步骤解决此问题:
1. 连接到主数据库
2. 使用 ALTER USER 语句以解锁用户账户
3. 连接到只读数据库
4. 重试之前的操作,以尝试在只读数据库上解锁用户账户
