The Messages dialog box has these components:
Measure execution time for SQL statements – enables or disables the ability of Interactive SQL to measure the time it takes for a statement to execute. When this option is enabled (which is the default), the time appears in the Messages pane.
Show separate Messages pane – lets you specify where information from the database server appears. By default, messages appear on the Messages tab in the Results pane. If you select this option, database server information appears in a separate Messages pane in the Interactive SQL window.
Default number of lines in Messages pane – lets you specify the initial height (in lines) of the Messages pane. The default is 7 lines.
