The Spool menu item saves all output to a specified file. Server Manager continues to save the output of your worksheet until you choose Stop Spooling from the menu.
The Write Log menu item writes the current contents of your worksheet's output pane to a specified file. The output pane contains the last 32 KB of output and the last 100 lines of text. The actual amount may vary by operating system.
Any text that has scrolled out of the output pane is also written to the file. However, if you have used the Clear Lines Off Top menu item to clear any lines from the output pane, those lines are not written to the file.
The Write Selection menu item writes any text you have selected to a specified file. You can select text from the input or output pane.
Additional Information: Server Manager appends a file extension, such as .log or .txt, to the name of each file created by the Spool, Write Log, and Write Selection commands. These file extensions are operating system-dependent. Refer to your operating system-specific Oracle documentation for information about the file extensions for your system.
