本文介绍了解决SQLPlus中出现'Connected to an idle instance'错误的方法。该错误通常发生在Oracle数据库环境中，当ORACLE_SID和ORACLE_HOME环境变量与数据库启动时使用的不匹配时出现。文章提供了检查背景进程中的ORACLE_SID和ORACLE_HOME并与当前会话进行比较的方法来定位问题。

关于sqlplus中出现"Connected to an idle instance"问题的处理：

该问题在如下文章中有解释：
How to Check the Environment Variables for an Oracle Process (文档 ID 373303.1)

如下是从该文章中摘录：

The most used application of this document is when dealing with the "Connected to an idle instance" scenario for a bequeath sysdba connection.
This error indicates that ORACLE_SID and ORACLE_HOME in the current session do not match the same environment variables that were used when the database is started (ORACLE_SID and ORACLE_HOME are the strings used to uniquely identify the shared memory segment of the instance when a connection is done).
Check the ORACLE_SID and ORACLE_HOME of the background process and compare them with the ones in the current session to find the mismatch.
