ORA-46075: Already attached to a lightweight user session ORACLE 报错 故障修复 远程处理

文档解释

ORA-46075: Already attached to a lightweight user session

Cause: The current database session is already attached to a lightweight user session.

Action: Detach from the current lightweight user session before attaching to the new lightweight user session.

ORA-46075:已被附加到轻量级用户会话

错误说明

ORA-46075指的是Oracle错误,表示有一个已被附加到轻量级用户会话的操作被发现。因此,这意味着正在尝试连接到Oracle数据库的会话已经附加到用户会话。这通常发生在当你试图重新连接到Oracle服务器时,并且你已经是轻量级会话的一部分。

常见案例

这种错误通常发生在以下类型的情况:

• 当一个正在使用某些类型的应用程序(如Oracle SQL *Plus)尝试重新连接时,该应用程序可能会发出“ORA-46075已被附加到轻量级用户会话”错误消息。

• 尝试在“SQL*Plus”中使用“CONNECT”语句将当前会话转换为“轻量级用户会话”时,也可能会发生此错误。

解决方法

要解决此错误,您需要确保您不会尝试重新连接到已附加到轻量级用户会话的会话,也就是说,您不应该在这种情况下使用“CONNECT”语句,因为它会导致“ORA-46075”错误。您可以使用“ALTER SESSION SET CURRENT_SCHEMA”语句将TNS会话转换为轻量级用户会话,而无需重新连接。

另一种解决方案是,首先断开与轻量级用户会话关联的会话,然后再重新连接。要断开会话,可以使用下面的SQL语句:

ALTER SYSTEM DISCONNECT SESSION ”;

就是您正在使用的会话ID。一旦您断开了会话,您就可以使用CONNECT语句重新连接。此外,你也可以重新启动 Oracle 数据库,以避免出现此错误。
