ORA-02087: object locked by another process in same transaction ORACLE 报错 故障修复 远程处理

文档解释

ORA-02087: object locked by another process in same transaction

Cause: A database link is being used in the cluster database environment that loops back to the same instance. One session is trying to convert a lock that was obtained by the other session.

Action: Get the more restrictive lock first. For example, if session 1 gets a share lock and session 2 gets an exclusive lock on the same object, get the exclusive lock first. Or, simply use the same session to access the object.

这是Oracle中一个常见的错误,它表示一个数据库对象已被同一个事务中的另一个进程锁定。

官方解释

ORA-02087: 表示请求的对象已由同一事务的另一个进程锁定。

常见案例

ORA-02087 错误通常发生在多进程环境中,例如该进程正在使用所请求的数据库对象,而别的进程也正在尝试访问它,从而导致发生错误。

正常处理方法及步骤

1.确定具体哪个进程正在使用该数据库对象(包括表上的锁定),按照以下步骤查询:

SELECT s.sid, s.serial#, s.username, s.program

FROM v$session s

WHERE s.program LIKE ‘%Object%’;

2.终止正在运行的进程 ($$kill),如果有必要可以查看V$LOCKED_OBJECT视图来确认进程是否真的被锁定了:

SELECT o.owner, o.object_name, o.object_type

FROM v$locked_object o;

3.重新尝试执行SQL,这样应该不会再次发生ORA-02087了,也不会影响其它进程的执行。
