ORA-02850: File is closed ORACLE 报错 故障修复 远程处理

文档解释

ORA-02850: File is closed

Cause: A file upon which an asynchronous I/O operation is to be performed has already been closed by the package.

Action: This is a programming error.

ORA-02850是一个在使用文件时引发的错误。 它的全文消息是“文件关闭”,用于指出数据库会话试图访问时已关闭。

官方解释

常见案例

正常处理方法及步骤

1.确保文件能够正常访问:确保与文件相关联的会话拥有文件打开所需的权限并且文件不存在于只读模式,或者已Forbid状态。

2.如果文件在实际使用中也可能被关闭,则需要在尝试访问此文件之前检查文件的状态:如果文件已关闭,则必须重新打开,然后才能进行安全操作。

3.在访问该文件时为它保留正确的模式:文件的可用模式取决于使用此文件的会话的权限。

4.确保文件在使用时安全有效:如果文件在使用中被连续关闭,则需确保文件在另一会话结束时可以重新打开。
