问题描述

我最近开始研究oracle数据库.通常，我有很多sqlplus窗口可以打开到不同的oracle数据库.从一个sqlplus会话切换到另一个sqlplus会话时，如何查看每个sqlplus会话的当前会话详细信息?任何帮助，我们将不胜感激！

I have very recently started to work on oracle databases. Generally I have many sqlplus windows open to different oracle databases. When switching from one sqlplus session to another, how can i view the current session details for each sqlplus session ? Any help is greatly appreciated!

推荐答案

看看这个 (c) Tanel Poder .您可以从glogin.sql运行它(因此这些设置将在每次连接时更新，或者只是手动运行.请注意host title命令-它更改带有会话信息的sql * plus控制台窗口标题-对于许多应用程序非常有用窗户同时打开.

Take a look at this one (c) Tanel Poder. You may either run it from your glogin.sql (so these settings will update each time you connect, or just run it manually. Notice host title command - it changes your sql*plus console window title with session information - extremely useful with many windows open simultaneously.
