SQLPlus Worksheet is a bit different from the other DBA Management Pack modules. It's essentially a command-line application dressed up in a GUI interface.
SQLPlus Worksheet, like SQL*Plus and Server Manager, allows you to execute SQL statements and view the results. Its display is divided into two panes.
The upper pane is where you enter and edit your SQL statements. The lower pane is where you view the results from executing those statements.
Instead of entering a semicolon or a forward-slash to have a statement executed, you click a lightning-bolt icon instead.
The following simulation shows you how to start SQLPlus Worksheet, execute a simple query, and then exit the application.
